1. New serious vulnerabilities spiked around release of Claude Mythos Preview

Security researchers observed a spike in CVE-severity around Anthropic’s Claude Mythos Preview release, signaling emerging vulnerabilities tied to a new LLM rollout and ongoing security risks in modern AI models. The pattern, tracked in epoch.ai data insights and discussed on Hacker News, suggests that new model releases continue to expand the attack surface and demand stronger guardrails and rapid patching. This could influence enterprise risk management and prompt-guarded deployment strategies across AI workloads. Source-rss

2. Meta, Samsung strike $6.5B 2nm MTIA AI chip deal

Meta Platforms and Samsung Foundry will manufacture Meta’s MTIA AI chips on a 2nm process, signaling a strategic shift away from TSMC and toward tighter control of compute for AI and cloud workloads. The deal is aimed at boosting Meta’s computing capacity for AI by 2030 and reducing reliance on external GPU supply, illustrating a broader hardware verticalization trend among major AI players. The move underscores how hardware choices are shaping AI competitiveness and cloud strategy. Source-reddit

3. Repeat-the-Text Leak Reveals AI System Prompts in Production

Security researchers demonstrated a zero-skill attack that retrieves an AI agent’s system prompt by typing a simple trigger, with tests showing roughly 60-70% of deployed agents leaking internal details. The finding highlights guardrail exposure, tool access, and API routing weaknesses that adversaries can map and exploit in production AI systems. It underscores the urgent need for robust prompt containment and defense-in-depth for real-world agents. Source-reddit
