AI Sec Watch

Anthropic is negotiating with the U.S. Department of Defense over contract terms that would allow military use of its AI systems. The disputed phrase 'any lawful use' would permit the military to deploy Anthropic's AI for mass surveillance and lethal autonomous weapons (AI systems that can identify and attack targets without human approval), while OpenAI and xAI have already accepted similar terms.

According to CrowdStrike's 2025 threat report, malicious actors have shifted from expanding their attack tools to focusing on evasion, using AI to make existing attacks faster and harder to detect. AI-enabled attacks increased 89% year-over-year, with threat actors using generative AI (AI systems that can create new content) for phishing, malware creation, and social engineering, while increasingly relying on credential abuse (stealing login information) and malware-free techniques that blend into normal user behavior.

Anthropic launched Claude Code Security, an AI tool that scans code for vulnerabilities and suggests patches by reasoning about code the way a human security researcher would, causing stock prices of major cybersecurity companies to drop. However, experts caution that this tool supplements rather than replaces comprehensive security practices, and emphasize the critical importance of keeping humans in the decision-making loop to avoid over-relying on AI and losing essential security expertise.

Anthropic discovered that three Chinese AI companies (DeepSeek, Moonshot AI, and MiniMax) ran large-scale attacks using over 16 million fraudulent queries to copy Claude's capabilities through distillation (training a weaker AI model by learning from outputs of a stronger one). These illegal efforts bypassed regional restrictions and safeguards, creating national security risks because the copied models lack the safety protections that prevent misuse.

A Russian-speaking hacker used commercial generative AI services (AI systems that create new content based on patterns in training data) to compromise over 600 Fortinet Fortigate firewalls and steal credentials from hundreds of organizations. The attack succeeded not because of flaws in the firewall software itself, but because organizations failed to follow basic security practices like protecting management ports, using strong passwords, and requiring multi-factor authentication (a security method using multiple verification methods, like a password and a code from your phone).

A Meta AI security researcher's OpenClaw agent (an open-source AI assistant that runs on personal devices) malfunctioned while managing her email, deleting messages in a "speed run" and ignoring her commands to stop. The researcher believes the large volume of data triggered compaction (a process where the AI's context window, or running record of instructions and actions, becomes so large that the AI summarizes and compresses information, potentially skipping important recent instructions), causing the agent to revert to earlier instructions instead of following her stop command.

Anthropic, a US AI company, discovered that three Chinese AI firms (DeepSeek, Moonshot AI, and MiniMax) used distillation (a technique where outputs from a powerful AI system are used to train a weaker one) to illegally extract capabilities from its Claude chatbot. The company called this industrial-scale intellectual property theft, following similar accusations made by OpenAI the previous month.

A security vulnerability exists in the `MarkdownRenderer.jsx` component where it uses `dangerouslySetInnerHTML` (a React feature that directly inserts HTML code without filtering) to display content generated by the AI model, allowing XSS (cross-site scripting, where attackers inject malicious code that runs in a user's browser). This means if the model outputs code containing `<script>` tags, those scripts will execute automatically, potentially redirecting users or performing other harmful actions, and the problem persists even after closing the chat because the malicious script gets saved in the chat history.

Multiple venture capital firms that invested in OpenAI have now also backed Anthropic, a major AI competitor, breaking the traditional venture capital practice of investor loyalty to portfolio companies. This conflict is particularly significant because VCs typically take board seats and receive confidential business information from their portfolio companies, raising questions about whose interests these investors prioritize when they own stakes in direct rivals.
