The story
Anthropic has limited the rollout of its Claude Mythos Preview model after its autonomous vulnerability exploitation capabilities triggered a 4.5% sell-off in U.S. cybersecurity stocks. The restriction follows an accidental data leak on March 27 that revealed the model’s advanced offensive security potential before its official announcement. CEO Dario Amodei acknowledged the unprecedented cybersecurity risks posed by the system, which can independently identify and exploit software flaws. Financial markets reacted sharply between April 7 and April 11 as investors priced in the threat of AI-automated attacks rendering current defense tools obsolete. Cybersecurity experts have expressed divided opinions on whether Mythos represents a net positive for defensive security or an unmanageable escalation risk. Anthropic stated the limited preview aims to gather safety data while preventing widespread misuse of the dual-use capability.
