  • •Chinese-speaking attackers used AI to breach 10 organizations.
  • •Over one million personal records were exposed during the attacks.
  • •The campaign is linked to Chinese intelligence operations.

From August to September 2026, Chinese-speaking attackers utilized the Cairn AI penetration testing framework to autonomously conduct 25 operations against at least 19 organizations. The attacks resulted in unauthorized access or data retrieval at 10 organizations, primarily in the semiconductor, defense, and civil society sectors. Attackers leveraged AI models Zhipu GLM and DeepSeek, requiring minimal input to execute complex tasks. Notable impacts included the exposure of over one million personal records and the creation of unauthorized administrator accounts. The campaign is assessed as intelligence collection linked to China, tracked as CL-STA-1238. The attackers operated from a server in Hong Kong and employed a customized version of Cairn, enhancing its capabilities with additional exploitation tools. This incident highlights the growing threat of AI-assisted cyber operations.
