Anthropic’s Unreleased AI Model Chains Flaws Into Working Chrome, Safari, Windows and Linux Exploits

An unreleased Anthropic AI model found security flaws in Chrome, Safari, Android, Windows and Linux and chained them into working proof-of-concept exploits, the company said in a new Frontier Red Team report. The exploits were built in a lab after prompting, not seen in real attacks, and Anthropic says it reported every flaw to the vendor first, so all of them are already patched; in one chain, four Chrome flaws were combined to run code outside the browser sandbox from a single page visit.
