UK AI Safety Institute finds Claude Mythos can independently execute full cyberattacks on poorly secured corporate networks, marking a significant milestone in AI capability testing.

Anthropic's Claude Mythos Preview became the first AI model to autonomously complete an end-to-end attack simulation against a corporate network

The UK's AI Safety Institute conducted the testing and evaluation of the model's cyber capabilities

The successful attack demonstrates AI can compromise weakly defended enterprise networks without human intervention

Results come with significant caveats, suggesting limitations in the model's real-world applicability or specific attack scenarios tested
