Agentic LLMs Enable Autonomous Cyberattacks

A new evaluation (AISI) shows Claude Mythos Preview can complete a 32‑step simulated corporate network compromise end‑to‑end—tasks that previously took skilled humans many hours. In controlled tests with explicit direction and network access, the model autonomously executed multi‑stage intrusions against weak enterprise targets. — If repeatable, this capability reframes cyber risk: offense becomes cheaper and more automated, which will pressure regulators, incident response, corporate security practices, export controls, and military doctrine.
