CISA uses Anthropic Mythos for code audits

The U.S. United States — Cybersecurity and Infrastructure Security Agency (CISA) is using Anthropic's AI model Mythos to audit government software for vulnerabilities, according to three sources. The scanning, conducted by CISA's Attack Surface Evaluation team, has already uncovered a large number of bugs. This deployment comes amid a rocky relationship between Anthropic and the U.S. government, including a Pentagon blacklisting that was blocked by a judge, and a recent export ban on Mythos and Fable that was lifted after negotiations. The United States — National Security Agency has also been using Mythos since April. The event highlights government adoption of AI for cybersecurity despite regulatory tensions.
