MINAKSHI DEBNATH | DATE: MAY 21,2025 Introduction: The Rise of Autonomous AI Agents In the rapidly evolving landscape of artificial intelligence, autonomous AI agents are transforming the way organizations manage cloud orchestration and DevSecOps. These intelligent agents can self-optimize, self-heal, and make decisions with minimal human intervention, leading to increased efficiency and scalability. However, this autonomy also introduces new cybersecurity challenges, as these agents can act unpredictably or be exploited by malicious actors. To address these risks, organizations must evolve their security strategies, particularly in the areas of red teaming and chaos engineering, to proactively identify and mitigate potential threats posed by autonomous AI agents. The Dual-Edged Sword of Autonomous AI in DevSecOps Autonomous AI agents are increasingly being integrated into DevSecOps pipelines to automate tasks such as vulnerability management, policy enforcement, and incident response. For instance, Opus Security has developed a platform that employs AI agents trained to discover known issues and suggest remediations, thereby reducing the noise level that legacy platforms typically generate. While these advancements offer significant benefits, they also expand the attack surface. AI agents with elevated privileges can be manipulated to perform unintended actions, leading to data breaches or system disruptions. Moreover, the complexity and opacity of AI decision-making processes make it challenging to predict and control their behaviour fully.   Red Teaming: Evolving to Address AI-Specific Threats Traditional red teaming focuses on simulating attacks to identify vulnerabilities in systems and networks. However, with the advent of autonomous AI agents, red teaming must adapt to address the unique characteristics of AI systems. AI red teaming involves simulating adversarial attacks on AI models to uncover weaknesses in their behaviour, data handling, and decision-making processes. Key differences between traditional and AI red teaming include: Broader Risk Scope:   AI red teaming addresses not only security vulnerabilities but also responsible AI issues such as fairness, bias, and hallucinations. Probabilistic Behaviour: Unlike traditional software, AI models exhibit probabilistic behavior, leading to varying outcomes under similar conditions. Dynamic Attack Surface:   AI systems continuously learn and adapt, requiring red teams to consider evolving threats and model drift. Organizations like Microsoft have emphasized the importance of understanding the system's capabilities and applications, highlighting that AI red teaming is not merely safety benchmarking but a proactive approach to uncovering real-world risks. Chaos Engineering: Stress-Testing AI Systems Chaos engineering involves deliberately introducing failures into a system to test its resilience. When applied to AI systems, chaos engineering can help identify how autonomous agents respond to unexpected inputs or environmental changes. This approach is crucial for understanding the limits of AI agents and ensuring they can handle real-world scenarios without compromising security or functionality. For example, by simulating network outages or data corruption, organizations can observe how AI agents adapt and whether they maintain compliance with security policies. Such testing helps in identifying potential points of failure and implementing safeguards to prevent AI agents from going rogue. Implementing Effective AI Red Teaming and Chaos Engineering To secure autonomous AI agents effectively, organizations should consider the following strategies: Develop Interdisciplinary Teams:   Combine expertise from cybersecurity, AI, and operations to create comprehensive red teaming exercises that address the multifaceted nature of AI systems. Adopt Continuous Testing:   Implement ongoing red teaming and chaos engineering practices to account for the dynamic nature of AI models and their environments. Utilize Advanced Threat Modeling:   Employ frameworks like MAESTRO to simulate attacks and assess vulnerabilities in AI agents, ensuring robust defense mechanisms are in place. Enhance Transparency and Explainability: Incorporate explainable AI (XAI) techniques to improve the interpretability of AI decisions, facilitating better monitoring and control. Implement Formal Verification Methods:   Use formal methods to verify AI agent behavior and ensure alignment with organizational goals and ethical standards. Conclusion: As autonomous AI agents become integral to cloud orchestration and DevSecOps, the importance of evolving red teaming and chaos engineering practices cannot be overstated. By proactively identifying and mitigating potential threats, organizations can harness the benefits of AI while safeguarding against the risks of agents going rogue. Embracing these advanced security measures will be essential in navigating the complex landscape of AI-driven operations. Citation/References: Vizard, M. (2025, March 3).

SHILPI MONDAL| DATE: AUGUST 22,2025 Introduction The rapid advancement of  artificial intelligence (AI)  and  machine learning (ML)  has created a new frontier in cybersecurity. While these technologies empower defenders, they have also been weaponized by cybercriminals to launch more sophisticated, scalable, and evasive attacks. This new era of  AI-augmented cybercrime  demands a fundamental shift in how organizations approach their digital defense, moving from traditional methods to AI-powered security strategies. The Rise of AI-Powered Cyber Threats AI has democratized advanced attack capabilities, allowing cybercriminals of varying skill levels to operate with unprecedented  scale and efficiency . AI-enabled attacks can automate the entire cyber kill chain, from reconnaissance to data exfiltration, reducing breakout times from days to minutes. These systems  learn and adapt  over time, creating attack patterns that are incredibly difficult for conventional security tools to detect. The economic incentive is clear: AI allows attackers to achieve a higher success rate with less effort, maximizing their return on investment. How Cybercriminals Weaponize AI and Machine Learning Hyper-Personalized Social Engineering and Phishing AI algorithms scrape public data from social media and professional networks to create  highly convincing, personalized phishing emails . These messages reference real projects, colleagues, or personal details, making them far more effective than generic scams. AI-powered chatbots can now engage victims in real-time conversations, building trust to steal credentials or deploy malware. Studies show AI-generated phishing emails can achieve a success rate comparable to those crafted by human experts. Sophisticated Deepfakes and Synthetic Media Using  Generative Adversarial Networks (GANs) , attackers create realistic fake audio, video, and images. This technology is used for executive impersonation to authorize fraudulent wire transfers, to spread disinformation, or to bypass identity verification systems. The sophistication is such that research indicates only  0.1% of people  can reliably distinguish deepfakes from real content. Evasive AI-Generated Malware AI can dynamically rewrite malicious code to  evade signature-based detection . Researchers have demonstrated that large language models (LLMs) can rewrite malware samples, causing AI-powered detection systems to classify them as benign in a majority of cases. This allows malware to adapt in real-time to its environment and persist undetected. Automated Vulnerability Discovery AI tools can automatically analyze codebases to find and exploit software vulnerabilities at a speed impossible for humans. Threat actors use LLMs to analyze public vulnerability reports (CVEs) and quickly develop functional exploits. Research shows AI agents can now autonomously exploit a significant percentage of critical vulnerabilities, drastically shrinking the window for defenders to patch systems. The AI Arms Race: Offensive vs. Defensive Applications Attackers’ Edge:   Cybercriminals exploit AI without ethical or regulatory limits, rapidly testing new techniques for maximum impact. Defenders’ Challenges:   Security teams must balance ethics, regulations, and complex integrations, slowing AI adoption. Defensive AI also needs quality data and validation before deployment.   Industry Trend:   Over 90% of AI security capabilities will come from third-party providers, easing adoption for organizations.   Defensive Strengths:   AI enhances detection, anomaly spotting, malware analysis, and vulnerability prediction. It automates monitoring and compliance, freeing experts to tackle high-priority threats. How to Fight Back: Defensive Strategies Deploy AI-Powered Security Solutions Fight AI with AI. Modern security platforms use  User and Entity Behavior Analytics (UEBA)  and AI-driven detection to establish a baseline of normal activity and flag subtle anomalies that indicate a breach. These systems can analyze vast amounts of data in real-time across endpoints, networks, and cloud environments to identify threats that would slip past traditional tools. Reinforce Foundational Cybersecurity Hygiene AI does not replace the basics. Robust defense still requires: Multi-Factor Authentication (MFA):  A critical barrier against AI-enhanced credential theft. Principle of Least Privilege:  Limiting user access to only what is necessary. Timely Patch Management:  Reducing the attack surface that AI scanners look for. Network Segmentation:  Containing the spread of any potential breach. Conduct AI-Specific Security Training Educate employees on the new threats posed by AI. Training should include: How to identify potential deepfakes and sophisticated phishing attempts. Implementing strict  verification protocols  for any unusual request, especially those involving financial transactions (e.g., a phone call to verify a wire transfer request received via email).   Develop and Test an AI-Aware Incident Response Plan Your incident response plan must account for the speed and adaptability of AI-augmented attacks. Conduct regular tabletop exercises that simulate these scenarios to ensure your team can contain and eradicate threats rapidly. Conclusion AI presents a dual-edged sword in cybersecurity. While it equips attackers with powerful new tools, it also provides defenders with the means to build more resilient and intelligent systems. The winning strategy is not to choose between AI and traditional methods, but to integrate them. By combining  AI-powered security platforms  with  strong foundational hygiene  and an  educated workforce , organizations can create a multi-layered defense capable of fighting back against the evolving threat of AI-augmented cybercrime.   Citations: Most common AI-Powered cyberattacks | CrowdStrike.

SWARNALI GHOSH | DATE: AUGUST 22, 2025 Introduction: Why You Should Care   APIs—short for Application Programming Interfaces—are the hidden highways behind the apps and services we use every day. From banking apps that ping your account balance to smart home devices that respond to voice commands, APIs connect systems and shape our digital world. But like any gateway, APIs can become a security weak spot. When hackers find flaws, they can slip through, expose private data, or disrupt services. Think of your favorite mobile app, the seamless online banking portal you use, or the smart home devices that adjust your thermostat with a simple voice command. The magic that makes all these digital experiences possible flows through a hidden network of digital gateways known as Application Programming Interfaces, or APIs. In today’s digital ecosystem, APIs act as silent enablers behind the scenes. They serve as communication bridges, allowing diverse software systems to exchange information, trigger actions, and work together seamlessly. When you check the weather on your phone, a weather app’s API is fetching data from a remote server. When you pay with PayPal on an e-commerce site, an API is securely transmits your payment details. But here’s the critical point every business leader, developer, and user needs to understand: Every API is a potential entry point for a hacker. If your front door is your login page, then APIs are all the side doors, back windows, and delivery chutes of your digital property. And attackers know it.   Why Are APIs Such a Lucrative Target?   APIs are targeted because they provide direct access to the valuable data and logic that power applications. Unlike a traditional website designed for human interaction, APIs are built for machine-to-machine communication. They are predictable, well-structured, and often process requests in high volume. This makes them perfect for automation—both for legitimate services and for malicious attacks. An attacker doesn't need to render a pretty webpage; they just need to find the right API endpoint, craft a malicious request, and see what data comes back. Having such an open channel for sensitive information makes it an irresistible target for attackers.   The Stakes: What Happens When APIs Fail   Recent research revealed how misconfigured APIs in corporate streaming systems allowed unauthorized access to sensitive livestreams—meaning team briefings or internal meetings could be exposed with minimal effort. This isn’t a fringe issue; less prominent platforms often rely on “security through obscurity” and lack robust safeguards. Pillars of API Security   Authentication & Authorization: OAuth 2.0 and JWTs (JSON Web Tokens) offer secure, token-based access, replacing risky practices like sharing passwords directly. Adopt Role-Based Access Control (RBAC) or even more dynamic Attribute-Based Access Control (ABAC) for granular permissions—e.g., approving transactions only within permitted limits. Avoid bearer tokens or API keys without expiration—they’re easily stolen or left lingering in code.   Encryption & Transit Security: Always use TLS/SSL encryption (HTTPS), preferably TLS 1.3, to protect data in flight from interception or tampering.   Gateways & Firewalls:   API Gateways act as your “digital bouncer,” validating requests, routing traffic, enforcing rate limits, and acting as a central control point.   Combine with a Web Application Firewall (WAF) for deeper traffic inspection. Services like LevelBlue + Akamai’s WAAP even add AI-driven detection, bot protection, and 24/7 expert support.   Input Validation & Schema Enforcement:   Never trust client input. Enforce positive security models (whitelisting expected formats/types) to reject any unexpected or malicious data.   Validate data type, length, range, and use schema libraries/frameworks like JSON Schema, Express-Validator, etc.   Rate Limiting & Throttling:   Prevent brute-force attacks or denial-of-service by limiting request rates using strategies like token buckets or sliding windows.   Inform clients properly—send a HTTP 429 Too Many Requests along with Retry-After, so API consumers know what’s happening.   Logging, Monitoring & Auditing:   Maintain comprehensive records that track which users accessed specific resources, at what time, and through which method. Track anomalies like repeated login failures, unusual spikes, or access patterns.   Use SIEM or analytics tools to detect and respond to threats in real time.   Secure Error Handling & Data Exposure Control:   Avoid verbose error messages that leak internal architecture details—keep it vague for end users, but log full context for devs.   Don’t expose excess data in responses: return only what’s necessary—no more.   Security Testing & Audits:   Conduct routine security reviews and penetration testing to identify weaknesses before attackers can exploit them. Use fuzz testing, parameter tampering checks, HTTP abuse tests, token validation checks, and injection testing to expose hidden flaws.   Integrate automated security scans into your CI/CD pipeline—so every code change is vetted before deployment.   Advanced Defenses: Service meshes can enforce mutual TLS (mTLS), zero-trust policies, and fine-grained controls between microservices—without code changes.   Threat Modelling, API Inventory Management, and robust Incident Response Planning are essential to managing evolving threats and ensuring preparedness.   Emerging Technologies: AI/ML offers dynamic threat detection by identifying anomalies in real time, while blockchain can enhance auditability and tamper-resistance. Building an Ironclad API Defense: A Multi-Layered Strategy   Protecting your APIs isn't about buying a single silver-bullet product. The goal is to foster a mindset where security takes priority and to apply layered protections at every level.   Shifting Security Left: Bake It In, Don't Bolt It On: Security cannot be an afterthought. Embed security practices throughout each phase of the software development lifecycle (SDLC). Design & Planning:  Use an API specification standard like OpenAPI to define exactly how your API should work. Tools can then automatically check for security anti-patterns before a single line of code is written. Development:  Train your developers on the OWASP API Security Top 10. Encourage peer code reviews focused specifically on security flaws like BOLA and data exposure. Testing:  Use dynamic application security testing (DAST) and static application security testing (SAST) tools that are specifically designed for APIs. Perform regular penetration tests that focus on business logic flaws, not just technical vulnerabilities.   Embrace Zero Trust: "Never Trust, Always Verify":  The old model of "trust but verify" is dead. Assume every request is malicious until proven otherwise. Strict Authentication:  Implement strong, standardized authentication like OAuth 2.0. Avoid rolling your own auth system. Fine-Grained Authorization:  Don't just check if a user is logged in. Check if this specific user has permission to access this specific resource on this specific endpoint. This is the ultimate defence against BOLA attacks. Validate Everything:  Treat all incoming data—whether in the body, headers, or query parameters—as untrusted. Enforce strict validation rules for type, size, format, and range. Know Your APIs: You Can't Protect What You Can't See:  Many organizations suffer from "shadow API" problems. These are old, forgotten, or undocumented APIs that are still running on servers, completely unmonitored. Strengthening security begins with building a thorough catalogue of every API in your environment. Use API gateways and management platforms to enforce consistency. Deploy tools that can passively discover APIs by analyzing network traffic, helping you find those hidden, risky endpoints.   Encrypt and Protect Data in Motion and at Rest: TLS Everywhere:  Use TLS across the board—ensure every API interaction runs over HTTPS (preferably TLS 1.2 or 1.3) with no exceptions. It encrypts data as it travels between the client and the server. Sensitive Data Handling:  Never store passwords in plain text. Implement robust hashing methods that are adaptive and include salting, such as bcrypt or Argon2. Consider encrypting especially sensitive data fields (like government IDs) even in your database.   Monitor, Analyze, and Adapt in Real-Time:  Because API attacks often involve probing business logic flaws, traditional signature-based firewalls can miss them. You need specialized protection. API Security Platforms:  Leverage modern solutions that use behavioral analysis. They learn the normal baselines of your API traffic—who calls what, how often, what the typical response looks like—and can instantly flag anomalies that indicate an attack in progress, like a sudden spike in 500 errors or a user accessing data at an impossible rate.   Call to Action: Stay Ahead, Stay Secure   API security isn’t a one-time checkbox—it’s a spectrum of practices that must evolve alongside threats. Every time you ship a new feature, run a deployment, or add an endpoint, ensure security checkpoints are part of the workflow.   Conclusion: APIs Are Your Business, Secure Them Like It APIs go beyond being mere technical tools—they serve as the backbone of digital transformation, shaping customer experiences and driving business innovation. Their security is not an IT problem—it is a core business imperative. A breach through an API can destroy customer trust, incur massive regulatory fines, and cause irreparable brand damage. By understanding the unique threats APIs face and implementing a proactive, layered security strategy rooted in Zero Trust and continuous monitoring, you can confidently unlock the power of APIs without leaving your digital gateways open to attackers.   Citations/References GeeksforGeeks.

SWARNALI GHOSH | DATE: AUGUST 19, 2025 Introduction: A Digital Petri Dish of Weak Habits   Credential stuffing isn't a flashy cyber-attack—but its consequences are real, rapid, and often invisible. In a world where recycled passwords are so commonplace, hackers leverage automated tools and stolen credentials to quietly infiltrate countless accounts. The result: A silent epidemic born from human convenience—and amplified by bot efficiency.   What Is Credential Stuffing—and Why It Works   At its core, credential stuffing is an automated replay attack: stolen username-password pairs from one breach are fed into other services in hopes of finding a match. This succeeds largely because password reuse is rampant—one source reports 81% of users reuse passwords across at least two sites, and 25% reuse the same password for most of their accounts. With tools like Selenium, OpenBullet, Sentry MBA, and voluminous “combo lists,” attackers attempt logins rapidly and at scale. Cybercriminals rely on automation platforms such as Selenium and credential-testing kits like OpenBullet or Sentry MBA, along with massive databases of stolen username-password combinations, to launch large-scale login attempts at high speed. With a success rate ranging from 0.1% to 2%, every million attempts can yield upwards of 20,000 compromised accounts.   A Growing Crisis Fueled by Data Leaks and Automation   Breach Fuel: Mountains of Stolen Credentials:   A study found 15 billion stolen login records from around 100,000 breaches.   In June 2025 alone, 16 billion credentials were exposed across 33 major incidents. According to Cybernews, an analysis of 19 billion exposed passwords collected between April 2024 and April 2025 revealed that just 6% were distinct, while a staggering 94% had been reused across multiple accounts.   Automation Makes It Cheap and Easy:   Attackers buy combo lists for pennies and employ bots, proxies, and CAPTCHA-solving services to mimic human behaviour and evade defences.   One report from ID Dataweb reveals a 50% increase in monthly credential stuffing attempts, 26 billion attempts per month.   Hard to Detect, Easy to Exploit:   Because these attacks leverage legitimate credentials, they often slip past traditional security measures. Bots mimic human-like patterns, evading rate limits and raising no alarms.   Real-World Impact: Financial & Data Fallout   Financial Losses Run Deep: Breaches linked to credential stuffing incidents carry a heavy financial toll, with the typical cost reaching as high as 4.81 million U.S. dollars.   Regulatory bodies like Australia’s APRA reported specific losses—for instance, AustralianSuper lost AUD 750,000 across several member accounts.   Catastrophic Breaches: An academic study revealed how reusing passwords in the breach of 23andMe in October 2023 led to the compromise of 5.5 million users, exposing genetic and personal data. Cybercriminals rely on automation platforms such as Selenium and credential-testing kits like OpenBullet or Sentry MBA, along with massive databases of stolen username-password combinations, to launch large-scale login attempts at high speed.   Chain Reaction Breaches: With so many credentials out there, one breach often seeds attacks across multiple platforms in a cyber-domino effect.   Why It's Still Rampant   Low technical bar, high yield: Attack tools and stolen credentials are cheap and accessible.   Slow detection timelines: On average, it takes organisations about 204 days to detect a breach caused by stolen credentials and an additional 73 days to fully contain it. Credential phishing & infostealers:  These fuel fresh credential dumps; phishing-delivered infostealers rose dramatically, leading to identity-based breaches accounting for 30% of intrusions.   Combating Credential Stuffing: Building a Secure Future   For Users: 1. Use unique, strong passwords (ideally with a password manager). 2. Activate multi-factor authentication (MFA) or passkeys. 3. Check if your credentials appear in breaches and update compromised passwords promptly.   For Organisations: Layers of Defence   A robust defence-in-depth approach includes:   Credential Screening at Sign-up/Login:  Block or reset accounts using previously breached credentials (e.g., via “EmailAge” risk scoring).   Adaptive MFA and Passkeys: Enforce additional verification only when needed; passkeys offer phishing resistance and seamless UX.   Bot Mitigation and Detection:  Fingerprint sessions, throttle rapid attempts, and deploy invisible challenges to disrupt automated attacks. Continuous Session Monitoring:  Watch for anomalies like impossible travel or escalation attempts, then terminate malicious sessions instantly.   Identity Threat Detection & Response (ITDR):  Leverage AI and behaviour analytics to detect credential abuse or identity attacks proactively.   Emerging Tech: Passkeys everywhere (FIDO2) reduce risk by making stolen passwords worthless. Browser attestation and invisible risk signals help verify trusted environments. AI-driven fraud prediction can anticipate attack spikes and pre-emptively tighten defences.   The Human Factor: Culture and Awareness   Strong technology isn't enough if password culture doesn't evolve. Research indicates that password reuse isn’t just a problem among everyday users—an estimated 92% of IT executives acknowledge repeating passwords across accounts. Public awareness campaigns and transparent breach notifications can shift the user mindset. After all, the weakest link often isn't the tool—but us.   Conclusion: Credential Stuffing—A Quiet Epidemic That Demands Our Attention   Credential stuffing is deceptively simple yet devastatingly effective. In an age defined by password reuse, attackers exploit human habits with the cold efficiency of bots. It's time for users, businesses, and regulators alike to treat this “silent epidemic” as the urgent crisis it is. For individuals: treat each password like a key—unique, strong, and never duplicated. For organisations: build layered, intelligent defences that disrupt automation without hindering legitimate users. Because in the digital age, security isn’t just about prevention—it’s about culture, vigilance, and evolving with the threat. Credential stuffing won’t vanish overnight, but with concerted effort, it can finally be contained.   Citations/References What is Credential Stuffing? | CrowdStrike.

SWARNALI GHOSH | DATE: AUGUST 13, 2025 Introduction The rise of Non-Fungible Tokens (NFTs) revolutionized how digital art is owned, sold, and valued. However, this transformation comes with growing cybersecurity challenges that artists, collectors, and platforms must navigate to safeguard digital art’s integrity. In this comprehensive exploration, we delve into vulnerabilities, legal gaps, protection strategies, and the future of NFT security. The rise of Non-Fungible Tokens (NFTs) has revolutionized the art world, enabling digital creators to monetize their work like never before. Yet, this breakthrough also introduces considerable challenges in cybersecurity. From phishing scams to smart contract vulnerabilities, artists and collectors face numerous threats in the NFT space. Protecting digital art requires a deep understanding of these risks and the best practices to mitigate them.   The Growing Importance of Cybersecurity in NFTs   NFTs are unique digital assets stored on blockchain networks, primarily Ethereum, Solana, and Polygon. While blockchain technology offers transparency and immutability, the surrounding infrastructure—wallets, marketplaces, and smart contracts—can be vulnerable to cyberattacks. According to a report by  Chainalysis , over $100 million worth of NFTs were stolen in phishing scams in 2022 alone. High-profile heists such as the Bored Ape Yacht Club (BAYC) Discord hack highlight the urgent need for better security measures.   The Illusion of Security: Ownership vs. Authenticity   An NFT verifies possession of its associated token, but not the actual artwork it represents. The token links to externally hosted content, which can be altered, removed, or replicated without the original artist's consent. The blockchain secures the token’s record, but not the artwork it points to.   Smart Contract Vulnerabilities: Manipulation at the Code Level   Security flaws in smart contracts are a real threat. For instance, researchers identified a critical "sleepminting" vulnerability that enables unauthorized transfer of NFTs. Their detection tool, WakeMint, found 115 instances of such flaws in over 11,000 real-world NFT contracts, achieving 87.8% precision. This highlights the critical importance of conducting thorough audits on smart contracts.   Centralization Risks: The Metadata Achilles' Heel   Many NFTs rely on centralized servers to store metadata (like images or descriptions). This creates single points of failure—content could be censored, tampered with, or lost over time. Instead, decentralized storage solutions like the InterPlanetary File System (IPFS) offer greater resilience, transparency, and control for creators and collectors.   Scams & Fraud: Cybersquatting, Rug Pulls, and IP Theft   The NFT space faces rampant financial and identity-related fraud:   Cybersquatting: Attackers create NFT collections that mimic popular originals. An analysis of 220,000 projects found 8,019 such collections, scamming over 670,000 victims for $59.26 million. Rug Pulls: NFT creators hype up projects only to disappear with investors’ funds. In one study, 37 rug pulls occurred within three months from the same creator, exposing repetitive fraudulent behaviour.   Unauthorized NFTs of Deceased Artists:  For example, following the tragic passing of digital artist Qinni, scammers minted her art without permission. Platforms are slowly introducing “verified artist” systems to address this, but comprehensive safeguards are still lacking. Platform Vulnerabilities: Unsolicited NFTs & Account Hijacks   Platforms like OpenSea have experienced serious security flaws. In 2021, vulnerabilities allowed malicious NFTs to hijack users’ accounts and wallets simply by being received. Users were urged to treat unsolicited NFTs with extreme caution.   Common Cybersecurity Threats in the NFT Space   Phishing Attacks and Social Engineering:  One of the most prevalent threats in the NFT ecosystem is phishing. Scammers impersonate legitimate platforms, sending fake emails or Discord messages to trick users into revealing private keys or connecting wallets to malicious sites. How to Avoid It: Never click on suspicious links. Verify official communication channels. Use hardware wallets for added security.   Smart Contract Exploits: Many NFT projects rely on smart contracts to automate sales and royalties. However, poorly coded contracts can contain vulnerabilities that hackers exploit to mint fake NFTs or drain funds. How to Avoid It: Audit smart contracts before investing. Use established NFT platforms such as OpenSea or Rarible for transactions. Research the project’s development team.   Fake NFT Listings and Counterfeits: Scammers often create counterfeit versions of popular NFTs, listing them on secondary markets at lower prices. Unsuspecting buyers may purchase fake assets, losing their funds. How to Avoid It: Verify NFT authenticity using blockchain explorers like  Etherscan . Check the official collection’s website and social media for verification.   Rug Pulls and Exit Scams: Some NFT projects are outright scams, where developers abandon the project after collecting funds from investors. How to Avoid It: Investigate the team’s credibility. Look for long-term project roadmaps. Avoid projects with anonymous developers.   Wallet and Exchange Hacks: Even if an NFT is secure, the wallet or exchange holding it can be compromised. Several centralized exchanges have suffered breaches, leading to massive NFT thefts. How to Avoid It: Use cold wallets (e.g., Ledger, Trezor) instead of hot wallets. Enable two-factor authentication (2FA) on all accounts. Legal Protections & Ownership Clarity   NFT ownership does not automatically convey copyright. Tokens may grant provenance, but artists often retain underlying rights—enforcement, however, remains complex. Cross-border enforcement, jurisdictional differences, and legal ambiguity present ongoing challenges. Additionally, U.S. regulators have urged new guidance to curb fraud and money laundering in NFT markets. Content Security: Watermarks, Metadata, and DRM   Protecting digital content demands more than blockchain security:   Watermarking & Metadata:  Embedding visible or invisible identifiers and licensing info can deter piracy or assist in enforcement, though they are not foolproof.   Digital Rights Management (DRM):  Enterprise-grade DRM integrated into marketplaces—such as Intertrust MarketMaker—offers robust content control, although interoperability remains challenging.   Best Practices for Artists and Collectors   Practical steps to strengthen security in the NFT space:   Due Diligence: Before investing, investigate the creators, review the project’s history, assess its rarity and utility, verify audit reports, and gauge the community’s perception.   Use Reputable Marketplaces: Stick to platforms with strong security reputations and verified procedures.   Avoid Blind-Signing Smart Contracts: Always review the permissions an NFT contract requests before approving any transaction.   Limit Unsolicited Interactions:  Reject NFTs or links from unknown senders; they could hide malicious code.   Spread Assets Across Wallets: To minimize total loss if one is compromised.   Use Hardware Wallets: These require physical confirmation and provide a strong defence against digital threats.   Ignore Suspicious Contact: Spam DMs or unsolicited offers may lead to scams.   Secure Wallet Access: Deploy encryption, multi-factor authentication (MFA), and consider cyber insurance covering blockchain assets.   Monitor Resources: Conduct regular audits and transaction oversight to detect anomalies early.   Emerging Tools & Innovations WakeMint: A solution developed to identify ‘sleepminting’ flaws in smart contracts before they can be exploited. Verified Artists Systems: Platforms like Twinci are rolling out identity verification akin to social media blue ticks to reduce fraud.   Standardization via EIPs: Building identity, authenticity, and blocklisting into NFT standards can strengthen ecosystem interoperability and security.   Cyber Insurance: Tailored policies now exist to protect wallets, platforms, and NFTs against hacking and fraud.   The Future of NFT Security   As the NFT market matures, security measures are evolving. Innovations like: Decentralized Identity Verification (e.g., ENS names for authentication) AI-Powered Fraud Detection (to flag suspicious transactions) Insurance for NFTs (some platforms now offer coverage against theft) will be essential in protecting digital artwork.   Conclusion   Protecting digital art within the NFT ecosystem is a multi-front battle. From smart contract flaws and centralized data vulnerabilities to sophisticated scams and legal ambiguities, the landscape demands a holistic approach. Security must be embedded from creation—across storage, legal frameworks, platform policies, and user practices. As tools and standards evolve—from WakeMint to decentralized storage and verified identity models—the ecosystem is strengthening. Yet, vigilance, education, and cooperation among creators, platforms, collectors, and regulators remain key. Ultimately, if the NFT marketplace is to mature beyond speculative hype, it must build robust, transparent, and resilient defences—so that digital art can truly thrive in a secure and trustworthy environment. The NFT space offers immense opportunities but is fraught with cybersecurity risks. By staying informed and adopting best practices, artists and collectors can protect their digital assets from theft and fraud. As blockchain security improves, the NFT ecosystem will become more resilient, ensuring a safer future for digital art ownership.   Citations/References Xiao, L., Yang, S., Chen, W., & Zheng, Z.

SHILPI MONDAL| DATE: JULY 30,2025 Introduction The field of  3D bioprinting  is revolutionizing medicine, offering the potential to create lab-grown organs, tissues, and implants tailored to individual patients. However, as this technology advances, so do the  cybersecurity risks  associated with it. Cyberattacks on bioprinting infrastructure could compromise patient safety, intellectual property, and even national security. This article explores the  emerging threats  to bioprinting systems, the potential consequences of cyber intrusions, and the  strategies needed to secure  this critical biomedical infrastructure. The Rise of Bioprinting and Its Cyber Vulnerabilities What is 3D Bioprinting? 3D bioprinting merges layer-by-layer fabrication techniques with biological materials to engineer living tissues and organs. Using bioinks—mixtures of cells, growth factors, and biomaterials—bioprinters construct complex biological structures layer by layer. Applications include:   Organ transplants  (e.g., kidneys, hearts) Drug testing models  (reducing animal testing) Personalized implants  (e.g., bone grafts, skin for burn victims).   Why is Bioprinting a Cybersecurity Target? Bioprinting relies on  digital workflows , including:   Medical imaging  (MRI, CT scans converted into 3D models) Automated printing systems  (controlled via networked software) Cloud-based data storage  (patient-specific genetic and biological data). These digital touchpoints create  entry points for hackers , who could: Alter organ designs  (leading to faulty implants) Steal proprietary bioink formulas  (valuable intellectual property) Disrupt biomanufacturing  (delaying life-saving treatments). Potential Cyber Threats to Bioprinting Infrastructure Data Manipulation in Digital Models Hackers could  modify 3D organ blueprints , leading to malformed tissues or non-functional organs. Example: A manipulated  heart valve design  could cause fatal complications post-transplant. Ransomware Attacks on Bioprinting Facilities Cybercriminals could  encrypt critical bioprinting files , demanding ransom to restore access. In 2021, a ransomware attack on  South Africa’s National Health Laboratory Service  paralyzed medical testing, showing how healthcare systems are vulnerable. Theft of Sensitive Biological Data Patient  genomic data  stored in bioprinting databases could be stolen and sold on the dark web. In 2020, a cyberattack on  Miltenyi Biotec  disrupted COVID-19 research, highlighting risks to biomedical data.   Sabotage of Bioprinting Equipment Attackers could  remotely alter printer settings , causing:   Overheating  (killing live cells in bioinks) Incorrect dosing  (toxic chemical releases) Mechanical failures  (ruining expensive bioprinted constructs).   Case Studies: Real-World Cyber Incidents in Biotech   The 2017 NotPetya Attack on Merck A  Russian-linked malware  attack disrupted Merck’s vaccine production, causing shortages of  Hepatitis B and HPV vaccines . Similar attacks could target  bioprinting facilities , delaying organ production. DNA-Based Malware in Synthetic Biology Researchers demonstrated that  malware could be encoded into synthetic DNA , potentially corrupting genetic databases used in bioprinting. Cyber Intrusions in Medical IoT Devices Insulin pumps and pacemakers have been hacked to deliver  lethal drug doses or electric shocks —raising concerns about  bioprinted organ control systems . Securing Bioprinting Infrastructure: Best Practices Implementing Zero-Trust Architecture Strict access controls  for bioprinting software and databases. Multi-factor authentication (MFA)  for all personnel. Encrypting Biological Data End-to-end encryption  for patient genomic data and organ blueprints. Blockchain-based verification  to prevent tampering with digital models. Air-Gapping Critical Systems Disconnecting bioprinters from the internet  when handling sensitive designs. Using standalone servers  for proprietary bioink formulations. Regular Cybersecurity Audits Penetration testing  to identify vulnerabilities. AI-driven anomaly detection  to spot unusual activity in bioprinting workflows. International Collaboration on Cyberbiosecurity The  WHO’s updated biosecurity guidelines  (2024) emphasize  cyber threats in high-containment labs , urging global cooperation. The Future: Ethical and Regulatory Challenges Who Owns a Bioprinted Organ? Legal ambiguity exists over  intellectual property rights  for bioprinted tissues. Should patients have full control over their  3D-printed organs , or do companies retain rights? Preventing Bioprinting Cyber Warfare Nations could weaponize  cyber attacks on bioprinting labs  to disrupt medical supply chains. The  U.S. Cyber-Biosecurity Nexus  report warns of  state-sponsored hacking  in synthetic biology. Standardizing Security in Bioprinting The  EU’s 2025 standardization workshop  aims to establish  cybersecurity protocols  for bioprinting. Conclusion As  3D bioprinting  advances, so must its  cybersecurity defenses . The stakes are high—compromised organs, stolen genetic data, and disrupted medical research could have  life-or-death consequences . By adopting  zero-trust frameworks, encryption, and international regulations , the biotech industry can safeguard this groundbreaking technology. The future of medicine depends not just on  printing organs , but on  protecting them  from cyber threats.

SWARNALI GHOSH | DATE: AUGUST 06, 2025 Introduction: The Evolution of Ransomware   Ransomware has long been one of the most feared cyber threats, crippling businesses, hospitals, and governments by encrypting critical data and demanding payment for its release. But in 2025, cybercriminals are no longer satisfied with just locking files—they’re now weaponizing reputational damage to force victims into paying. This shift has given rise to “ Reputationware ”, a more insidious form of ransomware where attackers don’t just hold data hostage—they threaten to expose it publicly unless their demands are met. From healthcare breaches that endanger patient lives to leaked corporate secrets that tank stock prices, the stakes have never been higher. This article explores how ransomware has evolved into a reputation-destroying weapon, the industries most at risk, and what organizations can do to protect themselves in this new era of cyber extortion. Ransomware is evolving. Once primarily a binary threat—encrypt files or pay—it has graduated into something far more insidious. The new variant, often called “ reputationware ,” focuses less on encryption and more on the public collapse of trust. Instead of—or alongside—file encryption, attackers are now holding reputations hostage. This article dives deep into how reputationware works, why it is emerging, real-world examples, and how individuals and enterprises can effectively respond.   What Is Reputationware ?   Reputationware refers to ransomware variants that emphasize exposure over encryption. Instead of—or in addition to—locking systems, attackers steal sensitive data and threaten public release unless demands are met. The "ransom" is not only restoring encrypted files, but also preserving trust, brand image, and legal compliance. The shift started as simple exfiltration in double‑extortion attacks. But it now stands on its own—pure data extortion without encryption, or worse, data tampering, manipulation, or misrepresentation to discredit the victim.   From Encryption to Extortion: The Rise of Double and Triple Extortion   Traditional ransomware attacks encrypt files and demand payment for decryption. But modern ransomware gangs have adopted double extortion—stealing data before encrypting it and threatening to leak it if the ransom isn’t paid. Now, some are taking it further with triple extortion, adding DDoS attacks or harassment campaigns to amplify the pressure.   How It Works   Data Theft Before Encryption:  Attackers exfiltrate sensitive files (customer records, financial data, trade secrets).   Public Shaming:  They create leak sites (like those run by LockBit, Qilin, and RansomHub) where stolen data is published incrementally to increase urgency.   Third-Party Pressure:  Some groups contact a victim’s clients, partners, or media to escalate reputational harm. Example:  In 2024, the Qilin ransomware group attacked a major NHS supplier, Synnovis, leading to patient harm and widespread media coverage. Even after negotiations, leaked data continued circulating, proving that paying doesn’t always stop exposure   Why Reputationware  Is More Dangerous Than Ever   The Psychological Warfare Factor:  Cybercriminals know that fear of reputational damage is often more compelling than operational disruption. A 2025 Sophos report found that 53% of victims paid less than the initial ransom demand, while 18% paid more, showing how negotiation tactics exploit panic.   Industries Most at Risk:  Some sectors are prime targets due to their reliance on public trust: Healthcare:  Patient data leaks can lead to lawsuits and regulatory fines. Legal & Financial Services:  Confidential client information is a goldmine for extortion. Technology & Manufacturing:  Intellectual property theft can destroy competitive advantage. Government & Education:  Public sector breaches erode citizen trust.    The Role of AI and Automation: Emerging groups like Fog and Anubis use AI-driven tools to automate data sorting, identifying the most damaging files to leak first. In some cases, attackers use AI to craft personalized blackmail messages specifically targeting company executives. Why the Shift Toward Reputation Extortion?   Encryption Is Noisy, Exposure Is Quiet, and More Effective:   Encryption alerts defenders; backups can help victims recover. But covert data exfiltration or reputational attacks bypass detection and leave no universal recovery options. Recent studies reveal that data theft is now part of 91% of ransomware incidents, shifting the focus of extortion toward damaging an organization's reputation.   Psychological Leverage Is Stronger:   Public embarrassment, regulatory penalties, and loss of customer trust can cause longer-term damage than a temporary system outage. Research from IBM and others emphasizes tactics like data tampering to sow doubt in a victim's internal systems—what’s worse than unrecoverable data is untrustworthy data.   Lowering Technical Barriers:   Pure exfiltration-based attacks often move faster, require less code sophistication, and avoid triggering encryption alarms. Reports from Dragos and SentinelOne describe “encryption-less extortion” and deceptive extortion, where attackers recycle or fabricate claims rather than actually encrypting files.   The Underground Economy of Reputationware   Ransomware-as-a-Service (RaaS) Boom:  Cybercriminals no longer need technical skills—they can rent ransomware tools from groups like DragonForce, Qilin, and LockBit. These affiliate programs take a cut of each ransom, incentivizing more attacks. Example: DragonForce’s AI-generated press releases taunt victims in real-time, adding humiliation to financial loss.   Dark Web Auctions for Stolen Data:  When victims decline to meet ransom demands, cybercriminals often resort to selling the stolen data on dark web marketplaces or offering it up to the highest bidder through underground auctions. In 2025, corporate espionage buyers are driving up prices for proprietary data.   Nation-State Collaboration:  North Korean hackers (like Moonstone Sleet) have been caught deploying ransomware, blending cybercrime with state-sponsored espionage. How Reputationware  Works: Anatomy of an Attack   Reconnaissance & Targeting:   Advanced actors research victims deeply—organizational hierarchies, regulatory omissions, sensitive relationships. Attackers are using AI-powered social engineering and deepfake technologies to craft realistic spear‑phishing campaigns, boosting infiltration success.   Initial Access & Credential Harvesting:   Early access methods include weak VPN credentials, brute‑force of remote access tools like AnyDesk or RDP. Once inside, attackers disable endpoint protections and spend time collecting data quietly.   Data Exfiltration and Tampering: Sensitive files are quietly siphoned off. In many cases, attackers go further: they subtly manipulate financial, legal, or clinical records to disrupt trust. Victims may receive ransom notes threatening manipulated data exposure unless paid, thereby undermining confidence in internal systems and audits. Public Exposure Threat: Unlike traditional ransomware that encrypts victims, reputationware groups threaten to publicly leak unless paid. Frequently, the ransom note asks victims to contact via Tor links without disclosing figures. If unpaid, sensitive data or claims are posted to leak sites. In some cases, attackers issue false claims—fabricating breach claims to maximize psychological pressure.   Real-World Incidents Illustrating Reputationware   Cl0p’s exploitation of Cleo Managed File Transfer:   Despite minimal file encryption, Cl0p extorted hundreds of victims through leaks of stolen data and threats alone.   BianLian’s transformation:   Once a double‑extortion actor, the group moved to pure data extortion—no encryption, only publishing sensitive victim data unless demands are met.   Babuk‑Bjorka and others: Publishing inflated or fabricated victim lists to amplify pressure, showing how deceptive claims serve as psychological weapons in reputationware  tactics.   Industry Trends: Reputationware  is Rising   Q1 2025 saw over 2,289 victims publicly claimed, a 126% year-over-year increase in published extortion incidents. Many of these were from groups like Cl0p and RansomHub using data leaks and reputation impact, often with little to no encryption. As noted in Dragos’s Q1 2025 industry analysis, encryption‑less extortion became more prevalent, and groups began relying on public exposure without encrypting files. Checkpoint and Palo Alto’s Unit 42 confirm increased activity around fabricated claims, tampering, and reputational threats across industries worldwide. Both IBM and Integrity360 have raised concerns about campaigns involving altered data, which erode trust, complicate recovery efforts, and intensify the pressure on victims during extortion attempts.   Who Is at Risk—and Why Reputationware Hurts More   High-impact sectors: Healthcare, professional services, finance, government, and IT:  Handling highly sensitive records that carry heavy consequences if leaked or manipulated. As of mid-2025, healthcare remains a top target due to legal and reputational exposure.   SMBs and mid-size businesses:   Small and medium businesses lack robust incident response plans and cybersecurity hygiene. In surveys, over 82% of SMB attacks result in disruption, and many businesses fail within six months of the incident. Reputationware  attacks can cause lasting damage to an organization’s public image, often making recovery nearly impossible.   Regulated industries: Data exposure triggers legal obligations under GDPR, HIPAA, or other data‑protection frameworks. Simply having breached systems—even without an operational blackout—can lead to fines, mandated disclosures, and loss of client trust. How to Defend Against Reputationware   Prevention: Harden Access & Patch Aggressively:   Implement multi-factor authentication, restrict remote access by geographic location, and establish strong password standards. Patch software promptly, particularly high-risk services such as VPNs, remote access tools, and file‑transfer systems.   Real-Time Monitoring & Data Loss Prevention (DLP):   Implement behavioural analytics, anomaly detection, and ADX (anti-data‑exfiltration) systems. These can detect unusual data movement or tampering attempts in real time, before exfiltration is complete.   Incident Preparedness & Trust Recovery Plans:   Don't rely solely on backups. Prepare for scenarios of tampered or leaked data. Develop communication and legal response protocols to mitigate reputational damage if exposure occurs.   Employee Training & AI Literacy:   Educate employees on evolving phishing threats, especially AI-generated or deepfake impersonation. Run ongoing training sessions and simulated exercises to raise awareness and reduce the risk of insider-driven security incidents.   Threat Intelligence & Leak-Site Monitoring:   Subscribe to threat‑intelligence feeds tracking leak‑site postings, fabricated claims, or group activity. Early detection of mentions on data‑extortion platforms may allow containment.   Conclusion: Reputationware  is the Ransomware Era’s New Weapon   As ransomware continues to evolve in 2025, reputationware  has emerged as a potent successor to classic encryption-based extortion. By threatening exposure, manipulation, or false claims, attackers can inflict long-term reputational and legal harm on organizations, often without ever locking a file. Defences must evolve, too. Organizations must combine technical controls with behavioral analytics, executive awareness, and legal readiness. In today’s threat environment, protecting your data means protecting your reputation, and staying proactive is your best insurance. Ransomware has evolved from a technical nuisance to a reputational doomsday weapon. With AI, automation, and psychological manipulation, attackers are refining their extortion playbooks—and no industry is safe. The only way to fight back is through proactive defense, rapid response, and global cooperation. Because in 2025, it’s not just about getting your data back—it’s about surviving the aftermath.   Citations/References Rapid. (2025, July 22). Q2 2025 Ransomware Trends Analysis: Boom and bust.

SWARNALI GHOSH | DATE: AUGUST 04, 2025 Introduction   Cloud security has always been a cat-and-mouse game between defenders and attackers. In the past, misconfigured Amazon S3 buckets have been the primary culprits behind massive data leaks, exposing sensitive corporate and customer information. However, as organizations increasingly adopt Software-as-a-Service (SaaS) applications, a new threat has emerged: SaaS misconfigurations. These misconfigurations are now leading to data breaches, compliance violations, and unauthorized access at an alarming rate. Unlike traditional infrastructure, SaaS platforms—such as Microsoft 365, Google Workspace, Slack, and Salesforce—are often managed by non-IT personnel, increasing the risk of security oversights. This article explores why SaaS misconfigurations are becoming the new S3 bucket leaks, how they happen, real-world examples, and best practices to prevent them.   The Legacy of S3 Bucket Leaks   Years like 2017–2019 featured notable exposures of sensitive data via publicly misconfigured Amazon S3 buckets: voter records, API keys, customer documents, and more were left open to the internet due to human error or weak policies, even after AWS had warned about the risks for years. Organizations such as Accenture, Verizon, and even U.S. government contractors saw serious reputational and financial damage simply because their admins had S3 buckets with “public‑read” ACLs or missing encryption. These S3 data exposure events acted as early warnings, leading cloud providers to introduce features like "Block Public Access" settings and enhanced auditing capabilities. More importantly, they marked a turning point in cybersecurity awareness, highlighting how simple configuration errors could evolve into major public incidents.   Enter SaaS Misconfigurations: A New Frontier Today’s SaaS misconfiguration isn’t about forgetting to block an S3 bucket—it's about granting overly broad permissions, leaving default settings in place, or misrouting APIs within SaaS services like Microsoft 365, Salesforce, Google Workspace, Slack, and GitHub. CrowdStrike defines SaaS misconfiguration as “incorrect or insecure configuration of SaaS apps that can expose sensitive data, grant unintended access, violate compliance, or enable breaches”. This ranges from file-sharing links set to “public” by default, to lax admin console settings, disabled MFA, and APIs mapping data incorrectly between systems.   Why SaaS Misconfigurations Are the Next Big Security Risk   The Shift from IaaS to SaaS Security Challenges:  In the early days of cloud adoption, Infrastructure-as-a-Service (IaaS) security risks—like exposed S3 buckets—dominated headlines. Companies learned to lock down storage permissions, but now, SaaS applications have taken center stage. Unlike IaaS, where security is more centralized, SaaS platforms are often managed by multiple departments (HR, Marketing, Sales), leading to inconsistent security policies. A Salesforce admin might inadvertently expose customer data, or a Microsoft 365 user could share sensitive files publicly without realizing the risk.   The Complexity of SaaS Permissions:  SaaS applications offer granular sharing controls, but this flexibility can backfire. Common misconfigurations include: Overly permissive sharing settings (e.g., "Anyone with the link" access in Google Drive). Incorrectly configured OAuth apps that have excessive permissions. Guest access abuse in collaboration tools like Microsoft Teams or Slack. A 2023 report by Adaptive Shield found that 63% of organizations had at least one critical SaaS misconfiguration, with Microsoft 365 and Google Workspace being the most commonly misconfigured platforms.   Shadow IT and Unmanaged SaaS Sprawl: Many employees use unauthorized SaaS apps (Shadow IT) without IT oversight. A McKinsey study revealed that the average enterprise uses over 200 SaaS applications, with only 50% being managed by IT. Unmonitored SaaS apps increase the attack surface, making it easier for attackers to exploit weak configurations.   Anatomy: Five Most Common SaaS Misconfigurations   Permissions sprawl & excessive access:  Too many users, teams, or service accounts are granted admin or edit rights, violating least-privilege principles. Disabled or absent multi-factor authentication (MFA):  Accounts powered by single-factor logins are easier to compromise, especially mail or file-app admins, where the blast radius is high.   Misconfigured sharing or API endpoints:  In the Microsoft Power Apps incident, more than 1,000 apps were left viewable online, exposing 38 million records, including PII, because shared APIs defaulted to public unless locked down manually.   API misrouting across SaaS->SaaS or SaaS->on-prem:  LinkedIn analysis by cybersecurity experts shows insecure OAuth2 flows and wildcard permissions can redirect data to unintended parties, even without stolen credentials.   Failure to enable logging or anomaly detection:  Many SaaS platforms ship with audit tools turned off, meaning suspicious access or data exfiltration goes unflagged until post-incident.   Root Causes: Why These Occur So Often   User convenience over security:  Including enabling functionality fast without reevaluating default access settings.   Shared‑responsibility confusion: Business units think security is built in “because it’s SaaS,” while IT assumes security is someone else’s domain.   Poor user interface (UI) clarity:  Labels like “organization,” “public link,” or “internal only” get misinterpreted: e.g., Salesforce admin UI caused several PII leaks for community pages due to ambiguous language.   Lack of centralized governance:  Hundreds of SaaS tools in use, but only 5–7 under the security team's observance; the rest are purchased.   Consequences: At Scale, Not Just Embarrassment   Mass data exposure at scale: 38M records in Power Apps can trigger regulatory fines (GDPR, HIPAA, CPRA). Targeted phishing / lateral movement: Exposed directories, tenant lists, or backup keys (as in the Commvault breach) reveal footholds into SaaS ecosystems.   Brand risk and customer distrust:  Once customers learn their app/data is “public by default,” trust erodes. Unlike S3 buckets (typically backend infrastructure), SaaS UIs are often user-facing.   Why Current Gartner-Like Tools Aren’t Enough   Static vulnerability scanning (e.g., prem or container scanning) doesn’t cover SaaS config drift caused by role changes or license activations. Visibility tools built into SaaS apps (e.g., Google Workspace, Microsoft 365) often lack enforcement controls or drift alerts. AppOmni reports reveal that only 13 % of organizations actually use SaaS Security Posture Management (SSPM) tools, which are purpose-built to continuously detect IPs and apply guardrails.   Real-World Examples of SaaS Misconfigurations Leading to Breaches   Microsoft 365 Misconfiguration Exposes US Defence Data (2022): A misconfigured Microsoft 365 SharePoint instance led to the exposure of sensitive US military documents, including contracts and personnel details. The files were accessible via public links without authentication.   Slack Workspace Leaks Employee and Customer Data (2023):  A publicly accessible Slack workspace allowed unauthorized users to join and scrape internal communications, customer support tickets, and API keys. The company only realized the breach after a security researcher reported it.   Google Drive Exposes Healthcare Records (2021):  A healthcare provider stored patient records in Google Drive with public sharing enabled, exposing thousands of medical files. The incident led to regulatory fines under HIPAA.   How Attackers Exploit SaaS Misconfigurations   Cybercriminals are increasingly targeting SaaS apps due to their widespread use and weak default settings. Common attack methods include:   Automated Scanning for Publicly Exposed Data:  Attackers use tools like GrayhatWarfare (formerly for S3 buckets) and GitHub dorking to find open SaaS documents, calendars, and databases.   Phishing via OAuth Apps: Malicious OAuth apps request excessive permissions (e.g., "Read all emails" in Microsoft 365). After gaining authorization, threat actors proceed to steal sensitive information or initiate ransomware attacks. Insider Threats via Overprivileged Users:  Employees with unnecessary admin rights can accidentally (or maliciously) expose data. A Salesforce admin might share a customer database externally without proper restrictions. Best Practices to Prevent SaaS Misconfigurations   Implement SaaS Security Posture Management (SSPM): Tools like Adaptive Shield, Obsidian Security, and AppOmni continuously monitor SaaS settings for misconfigurations.   Enforce Least Privilege Access: Regularly audit user permissions in SaaS apps. Remove unnecessary admin roles. Use role-based access control (RBAC).   Monitor and Restrict OAuth Apps: Review third-party app permissions monthly. Block high-risk OAuth scopes (e.g., full mailbox access).   Educate Employees on SaaS Security: Train staff on secure file-sharing practices. Implement Data Loss Prevention (DLP) policies to block sensitive data exposure.   Conduct Regular SaaS Security Audits: Use automated scanners to detect public-facing documents. Perform penetration testing on critical SaaS apps.   What Has Changed—and What Hasn’t? Richer default security tools:  Like Block Public Access for buckets or SSPM dashboards) exist, but people still leave them disabled or misinterpret them.   Threat actors are automated:  Just as automated scanners once scraped public S3 buckets, now bots scour SaaS tenants looking for open file links, API endpoints, or stale OAuth tokens.   Attack vectors have expanded:  A single misconfigured SaaS API can yield more access than a public S3 bucket ever could. Many files, mailboxes, backup sets, shared contacts, or AI model datasets may all be affected at once. In short, the actor mindset is the same—scan, find misconfiguration, download—but the tools and speed have changed significantly.   Conclusion: SaaS Security Can No Longer Be Ignored   While S3 bucket leaks remain a concern, SaaS misconfigurations are now a leading cause of cloud breaches. With remote work and SaaS adoption accelerating, organizations must shift their security focus to identity management, access controls, and continuous monitoring. By adopting SaaS Security Posture Management (SSPM) tools, enforcing least privilege access, and educating employees, businesses can mitigate these risks before attackers exploit them. The era of "set it and forget it" SaaS deployments is over—proactive security is the only way forward. The phrase “S3 bucket leak” once conjured images of someone leaving a data folder open on Amazon’s cloud. Today, “SaaS misconfiguration” is that evolving threat—often quieter, more complex, and potentially more damaging. Like S3 leaks before it, this problem isn’t going away. It can only be managed through a proactive security posture, automation, governance, and disciplined processes across the entire SaaS estate. You no longer need to scan buckets by hand. Instead, search for apps with “public data links enabled,” one-click admin consoles accessible outside secure zones, or APIs emitting sensitive PII to broad audiences. If your organization has heard “S3 buckets” as a risk in the past, it’s time to extend that caution to the hundreds of cloud apps your team depends on.   Citations/References Venkat, A.

ARPITA (BISWAS) MAJUMDER | DATE: AUGUST 01, 2025 Introduction: Love in the Time of AI   Imagine falling in love via video call—with someone who doesn’t exist. In the era of AI-generated media, romance scams have become frighteningly realistic, using deepfake videos and cloned voices to manipulate emotions and extract money. These are not mere catfishers—they are emotionally engineered fraudsters, powered by AI. A Dangerous Evolution in Scamming   What was once limited to text-based “catfishing” is now morphing into hyper-realistic emotional manipulation. Deepfake romance scams harness AI-generated video, voice, and chat tools to convincingly impersonate someone—and prey on victims’ hearts and wallets.   What Are Deepfake Romance Scams?   Deepfake romance scams are a modern evolution of traditional romance fraud: criminals deploy AI-generated videos, voices, profile images , and even chatbot conversations to impersonate romantic partners. They build trust, feign affection, and eventually request money under emotional pretexts, such as emergencies, investments, or travel. The emotionally intelligent fabric of these scams makes them harder to spot and vastly more believable.   How They Operate: Step by Step   Target Selection and Profiling:   Scammers often pre-screen targets—widowed or lonely individuals—via social media. In Hong Kong, one ring reportedly collected $46 million using deepfake romance scams.   Initial Contact: A deepfake persona—perhaps a model, actor, or digital nomad—initiates chat on dating sites or through direct messages. They may use stolen photos or AI-generated faces.   Relationship Building: Over days or weeks, the scammer sends affectionate messages, poems, or video calls that feel real—including real-time face-swapped AI. Over time, emotional trust becomes deep attachment.   Financial Requests: Once trust is gained, requests begin: travel funding, medical bills, fake emergencies, or investment opportunities. Victims have sent lavish amounts—some between £17,000 and £850,000.   Maintenance and Escalation: Scams can stretch for months or even years. Some perpetrators fabricate dramatic excuses: needing surgery, kidnapping, or legal trouble to extract more funds. Victims often experience significant debt and emotional trauma that may persist even after the scam ends. Why Deepfakes Make Romance Fraud More Potent   Ultra-realistic visuals and voices:  With just a few seconds of video or an image, scammers can create believable video calls or voice messages. In one case, an AI voice persuaded a finance worker in Hong Kong to transfer $25 million to a fake CFO.   Emotionally adaptive conversations:  Deepfake-enabled chatbots and AI (such as LLM tools) learn details about their targets—likes, names, interests—and adapt messaging dynamically, reinforcing a false bond.   Scalable personalization: Declared vulnerable ages and emotional states are targeted at scale, leveraging psychological triggers that encourage compliance.   Real Cases: Scams That Made Headlines   French woman & “Brad Pitt”:  Lost $850,000 over 18 months to AI-generated videos and texts from fake Pitt.   Nikki MacLeod (Scotland): A 77-year-old retired lecturer sent £17,000 to a fake offshore worker named “Alla Morgan,” convincing her via AI video.   Lisa Nock (UK): Fooled by a fake Dr. Chris Brown over 2½ years, handing over her monthly disposable income (~£40/month) and even being asked for £40 million.   Paul Davis (UK): Received AI-generated video from “Jennifer Aniston” that professed love, then sent Apple gift cards (~£200).   In each case, emotional manipulation combined with AI-made media made detection extremely difficult.   Why These Scams Are Growing   AI tools are now accessible:  Anyone can generate realistic deepfakes using open-source tools or web-based services. Public trust: Impersonating a public figure or injecting emotional intimacy significantly lowers victims’ skepticism.   Low legal risk:  Scammers often operate abroad, hide behind anonymized comms, and exploit legal gray areas. Victims may be too embarrassed to report.   Why These Scams Are So Effective Psychological manipulation: Deepfake technology enables empathetic, tailored messaging, making victims feel uniquely understood.   Lower barrier to entry: Accessible AI tools allow scammers to create believable deepfakes with minimal technical skill.   Limited detection tools: While detection research like DeepRhythm or WaveVerify exists, most victims lack access and awareness.   Rapid scale: Hybrid operations using AI and human oversight allow scammers to run thousands of concurrent tailored cases.   Impact: Emotional, Financial, Psychological   Victims face: Severe financial losses, sometimes life-altering (hundreds of thousands). Emotional devastation: grief, shame, depression, loss of trust. Lingering trauma, with many struggling to rebuild confidence.   Detection & Defense Measures Human Awareness Still Crucial:   As automated detection tools lag, human intuition and skepticism are more effective—especially during video calls. Weird eye movements, lip-sync issues, or frozen frames can be red flags.   Technological Aids: Tools like Vastav AI use metadata, image forensics, and confidence scoring to flag deepfake content. Some GAN-based systems report detection accuracy above 95%.   Platform Policy & Regulation: Several jurisdictions have enacted or proposed deepfake legislation: The U.S. TAKE IT DOWN Act mandates the removal of non-consensual deepfake imagery within 48 hours. The FBI and financial institutions issue regular alerts on romance fraud, including tactics involving AI and celebrity impersonation.   How to Protect Yourself   Verify their identity: Reverse-image search profile photos. Request a live video call with movement tests—turn heads, change expression. Realistic deepfakes struggle with dynamic motion.   Trust your instincts: Be suspicious of declarations of love within days or financial appeals under emotionally urgent contexts. Ask for consistent social media activity; new or inconsistent profiles are red flags.   Be cautious of financial requests: Never send gift cards or money to strangers online. Scammers prefer payments that are nearly impossible to reverse.   Use detection tools where possible: Tools like Vastav AI analyze metadata, heatmaps, confidence scores to flag deepfakes.   Report suspicious behavior: Contact law enforcement and report online scams to authorities such as the FBI's IC3. Broader Implications: Beyond Individual Victims   Financial fallout: Scams like this fuel global fraud, contributing to losses projected into the tens of billions annually.   Regulatory urgency: The EU's AI Act (2024) takes a strong risk-based approach, while tools like the proposed Digital India Act aim to address AI misuse.   Corporate risk management: Organizations must train staff to spot deepfake calls in business contexts—executive impersonation is now a major threat.   The Road Ahead: Trends & Challenges   AI sophistication will only increase:  Voice, video, photo and chat bots will become more lifelike and harder to detect. Detection tech must scale: Passive screening, real-time verification, and forensic watermarking will be essential.   Education is critical:  Widespread awareness campaigns can arm older and vulnerable adults against emotional manipulation.   Meanwhile, cross-sector collaboration between law enforcement, tech platforms, and financial regulators is vital to prepare for scams that increasingly blend emotional trust and synthetic intimacy. Conclusion: Love Isn’t Real Unless Verified Deepfake romance scams are the confluence of cutting-edge AI and emotional manipulation. They blur the line between virtual affection and cybercrime—leading to real financial and emotional damage. As these scams become more personalized, widespread, and technologically convincing, vigilance is your best defense. Protect yourself by verifying identities, resisting rapid emotional escalation, and asking questions. No matter how real it feels—it’s always worth confirming it's real.   Citations/References How romance scammers use deepfakes to deceive victims | McAfee AI Hub . (n.d.).

ARPITA (BISWAS) MAJUMDER | DATE: JULY 31, 2025 Introduction   In today’s rising tide of cyber‑threats, organizations are increasingly turning to cybersecurity war games—structured simulations pitting offense against defense—to sharpen their digital resilience. Known as Red Team vs. Blue Team exercises , these realistic drills immerse both sides in a battle of tactics, tools, and insight. Rather than summarizing, this article steps through each phase, explains real‑world examples, unpacks benefits and challenges, and explores emerging trends. Origins: From Military Strategy to Cybersecurity Practice Military roots: The concept originates in military exercises where Red Teams represented adversaries and Blue Teams friendly forces. The transition to cyber came naturally in the digital era. Historic precedents: Notable exercises such as the U.S. “Eligible Receiver 97” demonstrated the power of simulated cyberattacks and led to the establishment of U.S. Cyber Command. International evolution: NATO’s ongoing Locked Shields war game is now a flagship event, challenging national Blue Teams to defend critical infrastructure against simulated Red Team assaults. Defining Red Team and Blue Team Red Team:  Composed of skilled ethical hackers, attackers whose goal is to simulate real adversaries. They use penetration testing, phishing, exploitation, and even physical breach attempts to probe vulnerabilities.   Blue Team: The defenders. Internal security staff are dedicated to detecting, responding to, and mitigating attacks in real time using SIEMs, firewalls, threat hunting, and incident response protocols.   Roles & Objectives Red Team (Offensive Adversaries) Real‑world simulation:  Red Teams emulate the resources, tactics, techniques, and procedures (TTPs) used by sophisticated threat actors—from nation‑states to advanced persistent threat groups.   Goal‑oriented infiltration:  They breach systems using penetration testing, social engineering, phishing, credential theft, lateral movement, and stealth persistence—all under “red‑teaming” rules of engagement to avoid collateral damage.   Creative persistence: Only one successful exploit counts—even after dozens of failed attempts. This mirrors the mindset of actual attackers, honing unpredictability and persistence.   Blue Team (Defensive Guardians) Continuous detection and response: Blue Teams monitor logs, network traffic, and system alerts to spot anomalies in real‑time and execute incident response protocols. Hardening & remediation:  Based on Red Team findings, Blue Teams enhance defences, update configurations, apply patches, improve logging, and refine policies.   Structure of a Cybersecurity War Game Phase I: Planning & Rules of Engagement White Team governance: A neutral White Team sets the scope: boundaries, timelines, off‑limits assets, escalation paths, safety protocols, legal oversight, and ethics. Phase II: Reconnaissance & Attacks Red Team plays adversary:  Using OSINT, spear‑phishing, physical intrusion, or malware deployment based on MITRE ATT&CK or Cyber Kill Chain frameworks.   Blue Team monitors live:  Logs, intrusion detection systems, and alerts are scrutinized for signatures, suspicious behavior, unusual access, or lateral movement. Phase III: Engagement & Response Real‑time detection vs stealth attacks: Blue Teams strive to detect beachheads, eliminate persistence, and contain lateral spread. Red Teams test both stealth (“surgical”) and broad (“carpet‑bombing”) tactics to evaluate coverage gaps.   Phase IV: Debrief & Purple Teaming Detailed debrief:  Both sides join forces in a Purple Team session to unpack what worked, what failed, and how defenses can be improved collaboratively.   Metrics & lessons learned:  KPIs (e.g. time to detect, number of compromised hosts, coverage of MITRE ATT&CK tactics) will be evaluated. Recommendations feed into real‑world risk mitigation planning.   Purple Teaming: Bridging the Divide Purple Teaming integrates Red and Blue efforts, converting confrontational exercises into a collaborative learning environment. Real‑time feedback and joint planning accelerate remediation and improve detection mechanisms on the fly. Tools & Technologies in Use Red Team Engines: Metasploit , Kali Linux , Burp Suite , Empire , Wireshark , social engineering toolkits—used to simulate advanced attacker TTPs. Blue Team Arsenal: Splunk , Snort , OSSEC , SIEM platforms , firewalls, antivirus, threat‑hunting toolkits, and log analysis systems. Benefits of Red vs. Blue Exercises Realistic, adversarial testing:  By using live TTPs, organizations get exposure to attack styles and detect blind spots in people, processes, and systems.   Crisis‑ready incident posture: Exercises sharpen response behaviour under simulated pressure and stress conditions. Damage, disruption, or exfiltration are controlled but instructive.   Compliance & resilience building:  Regular exercises feed regulatory requirements (e.g., SOC‑2, ISO 27001) and support business continuity plans. Cross‑pollination of expertise: Purple teaming blends offensive insights with defensive improvements, ensuring mitigation tactics evolve to meet current threats. Real‑World Case Studies NATO’s Locked Shields: A flagship annual exercise run by NATO’s Cooperative Cyber Defense Centre of Excellence (CCDCOE) since 2010. Blue Teams from multiple nations defend against a Red Team simulating critical infrastructure assaults. The competition includes scoring and even legal‑media scenarios. In one year, the U.S. Blue Team finished 12th out of 19, with teams from the Czech Republic and Estonia outperforming them. Attacks included drone control hijacking and simulated air‑base sabotage—realistic and chaotic environments for training. Tri‑Sector Cyber Defense Drill (U.S., 2024): Companies across telecom, finance, and energy collaborated with CISA and government agencies in a multi-sector war game. Red and Blue Teams from different sectors cooperated, testing cross‐sector resilience, coordination, and incident response. This emphasised real‐world interdependencies.   Eligible Receiver 97: An early DOD scenario simulating Red Team intrusion into critical infrastructure and military command systems. Widely regarded as the founding moment behind the creation of U.S. Cyber Command.   Why These Exercises Matter: Benefits & Insights   Identifying Hidden Vulnerabilities: Simulating realistic threats exposes security gaps—technical, procedural, or human—that routine audits might miss. Improving Incident Response: Blue Teams sharpen real‐time detection and reaction under pressure, reducing the impact of real breaches.   Communication & Teamwork: Exercises foster cross‑team coordination and communication, breaking silos between IT, security, and leadership. Enhancing Security Awareness: Employees gain an understanding of phishing, social engineering, and broader threat landscape through exposure to actual simulations.   Compliance & Audit: Organizations improve audit readiness by demonstrating active testing and incident preparedness. Challenges & Pitfalls Resource Intensive: Designing, staffing, and running exercises demands planning, expertise, and tools—which may be expensive. Scope Creep: Without tight boundaries, exercises risk spiraling beyond manageable scale, overwhelming teams. Fatigue Effects: Repetitive drills without recovery can exhaust staff and reduce effectiveness.   Emerging Trends & the Future of War Games Automation & AI‑Driven Simulations:  Generative AI tools can now craft realistic phishing campaigns, simulate advanced persistent threat behavior, and scale scenarios beyond manual capabilities. Cyber Ranges: Virtual training environments like the DoD’s National Cyber Range Complex replicate large-scale, mixed Red/Blue/Gray environments at scale—from dozens to thousands of endpoints.   Ransomware Simulations: Events like Semperis’ ransomware war games simulate realistic chaos and multi-faceted disruption—requiring Blue Teams to adapt in near‑real time under unpredictable conditions.   Best Practices for Organizations Establish Clear Goals & Rules Up Front:  Define what systems, tactics, and boundaries are in play. Document Every Phase: Meticulous record‑keeping of reconnaissance, attack vectors, detection timelines, and responses.   Facilitate Purple Team Debriefs:  Ensure Red and Blue Teams collaborate post‑exercise—share lessons learned and remediation plans. Rotating Scenarios: Alternate internal and external threats, phishing vs. network vs. physical breaches. Regular Cadence: Move from periodic standalone Red Team engagements toward more continuous Blue Team operations integrated into a living security strategy. Conclusion Red Team vs. Blue Team cybersecurity war games are not mere drills—they are lifelike simulations of adversary tactics, designed to push both offense and defense to discover weaknesses, refine capabilities, and build resilience. Combined with Purple Team collaboration and increasingly enriched by AI and scalable cyber ranges, these exercises form the cutting edge of proactive defense. For modern organizations serious about staying ahead of evolving threats, structured war-game discipline is indispensable.   Citations/References Team, K. C., Theron, D., & Team, K. C.

ARPITA (BISWAS) MAJUMDER | DATE: JULY 30, 2025 Introduction: Trust, But Verify   Virtual Private Networks, or VPNs, promise encrypted tunnels, hidden IP addresses, and enhanced privacy. Yet for all their marketing appeal, VPNs are not foolproof shields—they offer only partial protection. Understanding where VPNs fall short is crucial to avoid a false sense of security.   VPNs Are Network Tools, Not Complete Security Solutions   VPNs serve as network routing tools, not comprehensive cybersecurity guards: They only protect data from your device to the VPN server. After exit, traffic is subject to the destination’s security measures like HTTP. Using a provider shifts trust from your ISP to them. If the provider logs or mishandles your data, privacy can collapse.   Leaks: DNS, WebRTC, Split-Tunnel — Hidden Privacy Gaps   Even with VPN connected, your traffic may still leak: DNS leaks can expose domain requests to your ISP, especially in split-tunnel setups or on Windows via Smart Multi‑Homed Named Resolution. WebRTC leaks let JavaScript reveal your true IP despite VPN activity, affecting many browsers. VPN configurations may allow local traffic to bypass encryption entirely if misconfigured.   Technical Vulnerabilities & Protocol Weaknesses   Many VPN protocols and clients harbor security risks: Outdated protocols such as PPTP and some L2TP/IPsec implementations are riddled with flaws and easily exploitable. Client software bugs have been found in popular enterprise clients (e.g. Cisco AnyConnect), leading to privilege escalation, code execution, and remote compromise. VPN servers and implementations also face threats like DoS attacks and memory flaws that disrupt service or enable exploitation.   Shared-Server Threats: Don’t Ignore Your Neighbors When multiple users share a VPN server, one compromised connection can affect another: Attackers on the same server port can craft packets to intercept or manipulate your traffic—analogous to Wi-Fi packet attacks.   Malicious or Poorly Managed Providers   Not all VPN providers prioritize user privacy: Free VPN services often monetize user data, incorporate ad tracking, and even deploy malware. A provider claiming “no logs” may still retain data or be coerced to share it. Users trust these services implicitly, but many fail audits or have unclear policies.   Man-in-the-Middle (MitM) Attacks & Credential Theft   VPN environments remain vulnerable to network-layer compromise: An attacker controlling your network can launch MitM attacks, intercepting or modifying traffic even over a VPN. VPN credentials stolen via phishing or malware can give full network-level access to an attacker.   VPN Is All‑Or‑Nothing Access — Not Granular VPNs typically grant broad network access: When you share VPN credentials, access is seldom compartmentalized. A compromised account can expose your entire network. VPNs also don’t enforce endpoint health—devices connecting may be infected or insecure, compromising the network indirectly. Survivor Bias: Untimely Patched Flaws Become Attacks   Real-world breaches highlight the risk of delayed patching: The Pulse Secure VPN breach allowed attackers prolonged access to sensitive entities due to unpatched zero‑day vulnerabilities. Enterprise VPNs are prime APT targets; patch delays expose users for extended periods.   User Misconceptions and Overconfidence   Public perception often overstates VPN benefits: A Tom’s Guide survey found many users mistakenly think VPNs provide full anonymity, stop social media tracking, or protect from malware—only a minority understand limitations. Many also believe VPN encrypts virus protection, which it doesn’t.   Real-World Exploits: When VPNs Fail The Pulse Connect Secure breach, exploited via a zero-day, allowed persistent access to U.S. government and corporate systems for months. Even a recent ExpressVPN bug inadvertently exposed IP addresses over RDP traffic on Windows—patched swiftly but revealing how rapidly vulnerabilities can happen.   Best Practices: How to Get More from Your VPN   To avoid over-reliance on VPNs, adopt these safeguards: Choose reputable paid providers with independent audits, transparent no-log policies, and strong encryption. Use VPN clients with strong protocols (e.g., WireGuard, OpenVPN with AES‑256), and avoid PPTP or weak legacy options. Enable kill-switch functionality so traffic stops if the VPN disconnects. Test for leaks using DNS/WebRTC leak tools, especially after setup. Use multi‑factor authentication and rotate credentials to reduce abuse risk. Pair VPN with endpoint security: antivirus, phishing filters, zero-trust network access (ZTNA), and SASE frameworks.   Conclusion: VPNs Help—but Aren’t Enough   A VPN can enhance privacy and protect data in transit—but it does not guarantee full security. Many assume encrypted traffic equals invincibility, but leaks, client flaws, malicious providers, and outdated protocols all pose real risks. Treat your VPN as one layer in a multi‑layered security posture—not the entire total solution.   Citations/References Why your VPN may not be as secure as it claims .
