With multiple benchmarks confirming that at least one frontier model can autonomously execute an end-to-end compromise, cybersecurity experts are warning that companies have to pick up the pace in securing their attack surfaces and adopting AI-speed defenses. On Sept. 2, consulting firm Booz Allen became the latest organization to confirm that a frontier model — Anthropic’s Mythos 5 — can act as a fully autonomous hacker and compromise a production-grade enterprise network. The company also released a metric, dubbed the Cyber Weapon Index (CWI), to benchmark a model’s capabilities, pairing the ability to find and exploit vulnerabilities with the ability to execute and attack a target.

Full report : Frontier AI models have already demonstrated they can autonomously — and in some cases, inadvertently — conduct end-to-end compromises, but the situation will become more urgent very soon.
