Kremlin-backed actors used Anthropic’s Claude AI to program autonomous lethal drones, improve hacking and influence operations, and avoid detection, the company said Thursday.The report from the U.S.-based AI company is only the latest warning from firms, think tanks, and others that Russia, China, Iran and others are using made-in-America tools to attack targets around the world.Anthropic reports that a Russian “freelance” group known as GTG-27005 used Claude to build an AI model small enough to work on single-board computers but powerful enough to enable a drone to “select targets (including a ‘person’ target class) and issue detonation commands without a human in the loop.” The group also used Claude to create software to allow autonomous drones to communicate with one another to improve targeting, Anthropic’s report says. While the Russian group had not yet deployed the model to the field, they were “using real hardware-in-loop testing within their sessions,” according to the report. The company banned the group, incorporated the findings of the investigation into its safeguards, and shared details with industry groups. Anthropic also said it had spotted Chinese and Yemeni groups trying to use Claude to design conventional weapons, efforts that Anthropic said it disrupted.The report also detailed how foreign groups were using Claude in elaborate data theft and disinformation campaigns. It said its tools had been used to dig up information about targets, find vulnerabilities in their online accounts, create malware to bypass security and steal data, cover their tracks, and spread disinformation.“We’ve seen groups of actors use Claude to build networks of fake social media profiles and entire news sites,” the report said.
