Anthropic confirmed it is investigating a report that a group gained unauthorized entry to its Claude Mythos model through a third‑party vendor portal. The breach, discovered via internet‑sleuthing tools and a developer portal, appears limited to exploratory testing rather than malicious exploitation. Anthropic’s Claude Mythos, released under the Project Glasswing preview, had been limited to a handful of trusted firms such as Amazon, Microsoft, Apple, Cisco and Mozilla, which used the model to identify hundreds of software flaws. The incident has revived concerns about AI‑driven cyber threats and the company’s recent designation as a supply‑chain risk by the U.S. Department of Defense. Read more →

Treasury Secretary Scott Bessent and White House chief of staff Susie Wiles joined the discussion, which the White House described as productive. While the Pentagon continues to challenge Anthropic’s models for military use, other agencies appear eager to explore the company’s technology for cybersecurity, AI safety and maintaining America’s lead in the AI race.
