Anthropic's Mythos AI model, touted as a breakthrough in finding software vulnerabilities, has been replicated using public AI models like GPT-5.4 and Claude Opus 4.6 by researchers at Vidoc Security. This replication shows that the ability to discover serious security flaws is no longer confined to elite labs, making vulnerability discovery cheaper and more accessible. While Mythos can create detailed attack blueprints, public models can already identify critical bugs, signaling a shift in cybersecurity dynamics. The challenge now lies in validating and mitigating these findings as AI-driven cyber risks spread.
