Alleged Knownsec Data Leak

In late October 2025, a significant data leak allegedly exposed the internal operations of Knownsec, one of China’s leading cybersecurity firms. This research report analyzes the 12,000+ file dataset to reveal a company operating under a "civil-military fusion" model. Publicly, Knownsec acts as a commercial innovator. However, it secretly serves as a contractor for Chinese state agencies like the Ministry of Public Security.
