The revelations in Anthropic's threat intelligence report come after a former top researcher at the company warned of the risks of AI to humanity.
Image source, Reuters By Laura Cress , Technology reporter  and  Nardine Saad Published 11 September 2026, 03:46 BST Updated 5 hours ago Anthropic says it has identified and disrupted attempts to use its AI model for "malicious activity" which could support the development of biological weapons.
The findings, made in the firm's recent threat intelligence report, is the latest in a growing series of warnings from AI researchers and industry insiders about the technology's potential risks to humanity .
The warnings have prompted calls to action, with US Senator Bernie Sanders demanding a pause on advanced AI development and a ban on artificial superintelligence.
President Donald Trump has so far rejected such fears, saying on Thursday he was concerned "if we don't win AI, we're going to be put in a very bad position".
The company published its latest threat intelligence report , external on Thursday.
Such reports have become a regular feature across the AI industry as firms seek to demonstrate how they identify and disrupt attempts to misuse their models.
This includes Google, which wrote on Tuesday , external that a person had attempted to use its AI tool, Gemini, to obtain a "complete, step-by-step technical guide for synthesizing weaponised biological agents".
Claude, Anthropic's AI model was also used by actors linked to a Russia-based cyber espionage campaign and by an Iranian propaganda institution, according to its report.
The cases of concern detected over the past eight months ranged from fake dating apps and hotel Wifi scams, to surveillance built to identify dissidents.
Anthropic has also accused Chinese AI firms of trying to replicate Claude's capabilities.
The lengthy report lists cases in which suspected state-sponsored groups, criminals, spyware vendors, state propaganda institutions and politically motivated individuals misused its technology.
"Malicious use" of its Claude Haiku, Sonnet, and Opus models was disrupted between December 2025 and August 2026, it said.
None of the misuse cases involved Claude Fable or the powerful Mythos-class models, with the exception of one instance of distillation - the process for training smaller AI models using larger, more expensive models.
As well as detecting the use of its models for cyber and influence operations, surveillance, scams and fraud and weapon development, Anthropic said it had blocked scientists who used its AI in ways that could support biological weapons development.
The report highlighted "five case studies of actors using our models in ways that could support biological weapons development".

OpenAI has formed a new independent mathematics advisory group hosted at the Institute for Advanced Study in Princeton following a surge in automated problem-solving. The move arrives amid mounting academic scrutiny regarding the rapid pace of artificial intelligence in advanced mathematical research.
As debate intensifies over the rapid acceleration of artificial intelligence, OpenAI has proposed a comprehensive framework for international safety standards, focusing heavily on alignment research and recursive self-improvement. The move follows recent high-profile departures and escalating concerns from industry insiders regarding humanity's long-term control over advanced frontier models.
As Washington fiercely debates artificial intelligence oversight, Nvidia CEO Jensen Huang has emerged as President Donald Trump's top confidant, successfully pushing back against growing regulatory pressures. While rival tech executives advocate for government slowdowns, the head of the world's most valuable chipmaker is charting a rapid course for American tech supremacy.
