Summary
Anthropic released Mythos Preview, an AI model designed to find and fix security vulnerabilities (weaknesses in software that attackers could exploit), and several US federal agencies are using it. However, CISA (the Cybersecurity and Infrastructure Security Agency, which is America's main government cybersecurity coordinator) reportedly does not have access to the tool, while other agencies like the Commerce Department and NSA do.
