Anthropic says Claude was misused in military and bioweapon attempts

Anthropic PBC said its Claude artificial intelligence model has been misused in attempts to develop a wide range of potential military applications, including kamikaze drone swarms, missile navigation systems and biological weapons. The company's disclosure describes misuse attempts rather than confirmed fielded weapons, and the summary does not state which actors were involved, when the attempts occurred, or whether any capability was achieved. Anthropic has separately published reports on Claude misuse across cyber, surveillance and weapons cases, making this the latest in a series of company-reported abuse findings rather than an independent verification.
