Anthropic blocks users over possible bioweapon research
Anthropic says it has blocked several users from its Claude AI platform this year after noticing activity resembling potential bioweapon research. The company spotted researchers circumventing geographic restrictions, obscuring their work's purpose, and tapping infrastructure linked to life sciences. In one case, a user sought Claude’s help drafting a grant for virus-modification research. Anthropic couldn't determine if the intent was malicious, but shut down access anyway.
- Anthropic blocked users after detecting suspicious biological research
- Some users hid locations using US-based systems
- Activity included drafting a grant for virus modification
- Company couldn't confirm if research aimed to cause harm
- Researchers tried to evade Claude's existing safety checks
