A new report from Anthropic reveals that adversarial actors, including Iran-linked groups and Yemeni Houthis, have used the Claude AI model to target U.S. naval forces and develop missile guidance systems. The 154-page document details various instances of misuse, including intelligence gathering, cyberattacks, and biological research, by actors based in Russia, China, and other countries. Anthropic has taken measures to ban offending accounts and share threat intelligence with government authorities to disrupt these malicious activities.
