Anthropic says it blocked state-sponsored attempts to use Claude for bioweapons research
Anthropic reported blocking approximately 35 state-sponsored attempts to use its Claude AI model for bioweapons research between November 2025 and September 2026. The company identified specific queries related to gain-of-function studies on viruses like chikungunya and bird flu, as well as research on lethal toxins. In response to these threats, Anthropic has implemented stronger safety protocols and restricted access to dual-use biological research in its latest models.
- ▪Anthropic identified about 35 distinct attempts by suspected state-funded actors to exploit Claude for bioweapons development.
- ▪Specific flagged activities included research on chikungunya virus transmission, bird flu adaptation to mammals, and orthopoxviruses.
- ▪The company noted that users employed anonymizing techniques to bypass regional blocking measures designed to restrict access in certain countries.
- ▪Anthropic has launched new models with enhanced safeguards that limit access to a wide range of dual-use biological research queries.
- ▪All suspect accounts were blocked by May 2026 for violating the company's Supported Regions Policy.
