GoKawiilAnthropic says Claude blocked five bioweapon-related requests tied to state actors
Anthropic's latest misuse report covers activity from November 2025 to September 2026 and details five cases where users tried to get its Claude AI to assist with dangerous biological research, three involving viruses and two involving toxins. In one instance, a request framed as a civilian grant application to enhance the chikungunya virus's mutation rate and virulence was traced to a military facility, prompting Anthropic to intervene. The company says all the actors used anonymization tools and tried to bypass its regional access blocks, which cover countries including China, Russia, Iran and North Korea.
