Anthropic said it had identified and disrupted attempts to use its AI model for “malicious activity” that could aid the development of biological weapons.

The disclosure, contained in the AI company’s latest threat intelligence report, adds to growing warnings from researchers and industry experts about the potential risks advanced AI systems could pose to humanity.

The concerns have sparked calls for stronger action, with US Senator Bernie Sanders urging a pause in the development of advanced AI systems and a ban on artificial superintelligence.

However, President Donald Trump has rejected such concerns, saying on Thursday that he was worried “if we don’t win AI, we’re going to be put in a very bad position.”

Anthropic published its latest threat intelligence report on Thursday, as AI companies increasingly release similar reports to highlight how they detect and disrupt attempts to misuse their models.

Google also said on Tuesday that an individual had attempted to use its Gemini AI tool to obtain a “complete, step-by-step technical guide” for synthesising weaponised biological agents.

Anthropic’s report said Claude had also been used by actors linked to a Russia-based cyber espionage campaign and an Iranian propaganda organisation.

The cases detected over the past eight months covered a range of activities, including fake dating apps, hotel Wi-Fi scams and surveillance tools designed to identify dissidents.

Anthropic also accused Chinese AI companies of attempting to replicate Claude’s capabilities.

The lengthy report detailed cases involving suspected state-sponsored groups, criminals, spyware vendors, propaganda organisations and politically motivated individuals who allegedly misused its technology.
