Why Anthropic’s Mythos Is Sparking Global Alarm

Anthropic PBC has said its new artificial intelligence tool, Mythos, is so good at finding vulnerabilities in software and computer systems that it can’t be released to the general public. The AI giant released Mythos to a limited number of carefully chosen parties because if a tool this powerful fell into the wrong hands, Anthropic says, it could help attackers more easily steal data or disrupt critical infrastructure.

That risk was underscored when a small group of unauthorized users in a private online forum gained access to Mythos, according to a person familiar with the matter and documentation viewed by Bloomberg News.
