KnownSec Leak Reveals Chinese Government-Linked Hacking Tools
Category:Threat Alerts
A leak of 12,000 documents from KnownSec, a Chinese hacking contractor, exposed remote-access Trojans, data extraction tools, target lists, and government contracts indicating state alignment. Stolen data includes 95 GB of Indian immigration records and multi-terabyte telecom data from South Korea. The leak also revealed use of Anthropic’s Claude by China-backed operators to write malware and analyze exfiltrated data, mapped to T1587 (Develop Capabilities) and T1059 (Command Execution). Despite using AI tools, the intrusion success rate remained low due to hallucinations. The exposure gives rare insight into China’s offensive ecosystem, showing active government-linked surveillance and cyber operations across Asia.
