Anthropic blocks efforts to use AI to research weapons development and carry out cyber attacks | World News
Anthropic says it has blocked efforts to use its artificial intelligence models to carry out cyber attacks and research which could have led to the creation of biological weapons. The US company has published a lengthy report into AI misuse, including instances of malicious code and dangerous prompts it has discovered in its models. Between December 2025 and August 2026, Anthropic’s researchers identified misuse by “politically motivated individuals, state-sponsored groups seeking to spread propaganda, and spyware companies”. It blocked one request for Claude to help create a grant application for scientific funding into research to “create a new or enhanced biological property” of the chikungunya virus. The mosquito-borne virus triggers symptoms such as severe pain and fever, and the request sought to enhance mutations to make the virus more harmful. Anthropic said it could have been “used to make the pathogen more dangerous”.
