Claude Mythos Preview Is Everyone's Problem

Anthropic says its new Claude Mythos Preview can autonomously uncover thousands of serious software vulnerabilities, including in major operating systems and browsers.

The company is not releasing the model publicly and is limiting access to selected large tech firms for security scanning.

Anthropic says the capability could help defenders, but it also raises concerns about offensive cyber use and exploit development.

The stakes are high for infrastructure, banks, and government systems if powerful vulnerability-finding tools are misused.
