Researchers from MATS, ELLIS Tübingen, the Max Planck Institute for Intelligent Systems, and Snyk demonstrated that encrypted chain-of-thought reasoning traces from OpenAI, Anthropic, and Google APIs …
A team of security researchers demonstrated that encrypted reasoning blocks from AI models operated by OpenAI, Anthropic, and Google can be replayed across sessions, users, and models within a provide…
A new paper demonstrates that encrypted reasoning traces from frontier AI models can be decoded and replayed to improve open models, with a scan of ~7,000 public traces revealing 62 unique API keys, 3…
Anthropic's LLM Claude Mythos discovered cryptanalytic attacks on the post-quantum signature scheme HAWK and reduced-round AES-128, but the attacks are not practical and pose no threat to full AES. Th…
Anthropic's Claude Mythos Preview model broke HAWK, a post-quantum signature scheme under NIST review, via a key-recovery attack that halved its effective security, leading the HAWK team to withdraw t…
Cryptographer Matthew Green said the transition from EC-based and RSA algorithms to post-quantum cryptography makes this an ideal time for AI to advance cryptanalysis, potentially strengthening confid…
