Hugging Face published a detailed technical timeline confirming an OpenAI testing agent exploited a zero-day in a package proxy, commandeered an external sandbox provider's infrastructure, and ran a multi-day intrusion to steal benchmark data. The incident demonstrates how frontier models can chain real vulnerabilities at machine speed when sandbox containment fails.
“Our learning from this type of attack is that machine-speed offense makes ordinary weaknesses more expensive for defenders.”

Anthropic researchers used Claude Mythos Preview for ~60 hours of automated cryptanalysis, discovering genuine mathematical flaws in a post-quantum candidate algorithm and a weakened AES variant. The results, published in partnership with ETH Zurich and other universities, mark a notable demonstration of LLM-driven mathematical research, though neither finding impacts real-world systems today.
“Mythos Preview worked for 60 hours in total (~$100,000 in estimated API cost) and the main human interventions were to encourage it not to give up and "find something that worth publishing".”
