Anthropic published a threat-intelligence report describing how malicious actors tried to use Claude for cyber, surveillance, influence, scams, biological misuse, conventional weapons, and illicit distillation, and how Anthropic disrupted the operations and updated safeguards. The cases it covers span from December 2025 to August 2026, using Claude Haiku, Sonnet, and Opus models. As a result, Anthropic says safeguards were strengthened based on what was learned and intelligence was shared with authorities and industry partners where appropriate, while noting AI-fueled misuse has evolved since earlier reports.
