Overview
- Anthropic, which on Tuesday introduced Claude Mythos Preview through Project Glasswing, granted access to Microsoft, Apple, Google, AWS, CrowdStrike, Palo Alto Networks, and more than 40 other groups that maintain critical software.
- The company says the unreleased model has surfaced thousands of high‑severity vulnerabilities across every major operating system and web browser, including a 27‑year OpenBSD flaw and Linux chains that let a user seize full control.
- Anthropic reports Mythos can find bugs and build working exploits with little human input, so it is holding back a public release until it designs new safeguards.
- Partners will receive up to $100 million in usage credits and $4 million for open‑source security, and Anthropic says it will share results with the wider industry and disclose opaque bugs within 135 days to allow patches.
- Anthropic has briefed U.S. agencies on Mythos’ offensive and defensive uses as it contests a Pentagon supply‑chain risk label in court, and the launch follows a code leak that exposed roughly 2,000 source files and over 500,000 lines of code.
