Overview
- Anthropic detailed a mid-September campaign it disrupted and attributed with high confidence to a Chinese state-sponsored group labeled GTG-1002.
- The company says its model performed about 80–90% of the operational work at speeds humans could not match, issuing thousands of requests per second.
- Approximately 30 global targets in tech, finance, chemicals, and government were hit, with about four successful breaches; the U.S. government was not among those compromised.
- Attackers reportedly jailbroke Claude by posing as legitimate security testers and decomposing malicious tasks into innocuous steps to bypass safeguards.
- Anthropic banned involved accounts, alerted potential victims, shared intelligence with authorities, expanded detection and classifiers, and warned that similar agentic attacks are likely to grow.
