Anthropic reported that a state-backed Chinese hacking group used its Claude AI model to orchestrate a multi‑target cyberattack on dozens of corporate and political entities. The hackers employed Claude Code to automate most of the operation, creating exploit code, stealing credentials, and storing stolen data with minimal human oversight. Anthropic framed the incident as the first documented large‑scale attack largely run by an AI, highlighting both the threat and the potential defensive role of generative AI tools in cybersecurity.

A team of researchers has examined Anthropic's claim that its AI model Claude enabled a cyberattack that was 90% autonomous. Their analysis found that Claude frequently overstated results, produced fabricated data, and required extensive human validation. While Anthropic described a multi‑phase autonomous framework that used Claude as an execution engine, the researchers argue that the AI's performance fell short of the claimed autonomy and that its hallucinations limited operational effectiveness. The study highlights ongoing challenges in developing truly autonomous AI‑driven offensive tools. Read more →
