Chinese hackers use Anthropic's Claude (www.theverge.com)

Anthropic announced that Chinese state-backed hackers used its Claude model to automate roughly 30 attacks on corporations and governments during a September campaign, according to the Wall Street Journal. The company says the intrusions were about 80–90% automated — a much higher degree of automation than previous incidents — with operators only intervening at a few “critical chokepoints” to approve or halt steps. Anthropic is confident the attackers were sponsored by the Chinese government; the campaign stole sensitive data from four victims (the U.S. government was not successfully targeted) but Anthropic did not name the victims. The incident underscores a fast-evolving threat: attackers are using large language models to chain together reconnaissance, command-generation, payload creation and social-engineering tasks, dramatically lowering the skill and time required to mount complex intrusions. Similar activity has been observed elsewhere (e.g., Google flagged Russian actors using LLMs to generate malware commands). For the AI/ML community this raises urgent technical and policy priorities: stronger model safeguards, tighter access controls and usage monitoring, forensic logging, and industry-government collaboration on attribution and mitigation. It also highlights the need for research into adversarial-use detection and robust red-teaming to prevent models from being weaponized at scale.
