Anthropic Investigates Unauthorized Access to Claude Mythos

Anthropic is investigating reports of unauthorized access to "Claude Mythos," a powerful and private artificial intelligence model ^[1][2]. The company kept the tool restricted because it can identify and exploit zero-day vulnerabilities across major operating systems and web browsers ^[1][3].

Reports suggest an unauthorized group successfully gained access to the restricted tool ^[3]. This incident has triggered significant cybersecurity concerns in Washington and among global security experts ^[2].

The potential exposure of a tool designed for exploit discovery represents a serious threat to digital infrastructure ^[1][2]. Anthropic has not yet confirmed the full extent of the reported data breach ^[2].
