Users in Houthi-Held Yemen Tried to Develop Advanced Weapons with AI, Anthropic Says
Anthropic said the group used Claude across three weapons programs and that it found no evidence of a working weapon.
- On Thursday, September 10, Anthropic published a threat intelligence report revealing Houthi rebels attempted to use Claude to develop missile guidance software across three weapons programs in Yemen.
- Operators used Claude "in place of human software engineers" between December 2025 and August 2026, splitting tasks across sessions to evade safety safeguards, according to the report.
- The weapons programs included a ballistic missile designed to reach ranges above 2,000 km. Anthropic also flagged three Iranian state-aligned accounts, a Russia-linked espionage operation, and blocked biological weapons efforts.
- A California judge ruled unlawful the Pentagon's decision to blacklist Anthropic as a supply chain risk over its refusal to strip safeguards from autonomous weapons.
- Researcher Jacob Coxon resigned on Tuesday, September 8, warning that "the people building AI earnestly believe that it could kill us all by the end of the decade." Alignment Science Lead Evan Hubinger estimates greater than 10% chance of human extinction.
