   Anthropic Report Links Iran, Houthi Rebels to AI Use for Naval Targeting

   Anthropic disclosed in a 154-page security report that Iran used its Claude AI model to gather open-source intelligence to target US Navy ships in the Middle East and research vulnerabilities in shipborne systems. The company also found Houthi rebels in Yemen used the chatbot to assist in weapons development, including coding ballistic missile guidance systems and attempting to build hypersonic missiles. The report further identifies efforts to use the AI for espionage and biological weapons research.

   Why it matters

   This incident highlights the risk of large language models being repurposed for military intelligence and weapons engineering. It occurs amid heightened tensions in the Middle East involving Iranian-backed groups and US naval assets.

   What is confirmed

   • Iran used the Claude AI model to target US Navy forces in the Middle East.
   • Houthi rebels in Yemen used Claude to develop ballistic missile guidance systems and hypersonic missiles.
   • Anthropic released a 154-page security report detailing these AI abuses.

   Still unconfirmed

   • Users attempted to carry out biological weapons development using the AI.

   What to watch next

   • US Navy response to identified shipborne system vulnerabilities
   • Anthropic updates to safety filters regarding weapons engineering

   Anthropic Says Iran Used Claude AI to Target US Navy

   Anthropic reports that Iran and Houthi rebels utilized its Claude artificial intelligence model to conduct malicious cyber operations, build targeting material against United States Navy warships in the Middle East, and assist in weapons development. According to the company, users in Houthi-held Yemen also attempted to use the chatbot to develop advanced weapons, including building hypersonic missiles and coding ballistic missile guidance systems. The artificial intelligence firm disclosed these findings in a September 2026 report detailing various disruptions of bioweapons research and espionage attempts.

   Why it matters

   The misuse of commercial artificial intelligence models for military targeting and advanced weapons design highlights growing concerns over the proliferation of dual-use technologies by state and non-state actors. Anthropic's public disclosures reflect an increasing effort by technology companies to monitor and report how foreign actors exploit generative tools for espionage, cyber operations, and tactical military applications.

   What is confirmed

   • Anthropic reported that Iran and Houthi rebels used its Claude AI model to target U.S. Navy warships in the Middle East.
   • An Iran-linked group used Claude to track U.S. Navy ships and build targeting material from publicly available data.
   • Users in Houthi-held Yemen tried to develop advanced weapons and code ballistic missile guidance systems using the AI bot.
   • Anthropic blocked possible efforts to build biological weapons during the same monitoring period.

   Still unconfirmed

   • Diesel prices in the United States hit six dollars a gallon as Houthi rebels took the Red Sea port city of Mokha.

   What to watch next

   • Further official disclosures from technology firms regarding state-sponsored artificial intelligence exploitation
   • Additional regulatory responses or investigations concerning dual-use AI security controls
