Moyun Technology

Moyun Technology (墨云科技) is a Beijing-based AI-driven cybersecurity company founded in 2017 by Liu Bing . It distinguishes itself from the mainstream defensive approach by specializing in offensive security—using AI to simulate hacker attacks and test the integrity of clients' IT defenses . Its flagship product is the Vackbot virtual hacker robot, which automates security attack detection and validation across the full chain from external networks down to individual functions .

The company positions itself as the only domestic vendor covering complete-chain automated security verification, and claims its approach can reduce external vulnerability reports by over 70% . It has been recognized by Gartner as a benchmark enterprise in both BAS (Breach and Attack Simulation) and SCA (Security Control Assessment) categories, and was selected for the 2022 Red Herring Global 100 . BlueRun Ventures led its Series A and has continued to back it through multiple subsequent rounds, with a strategic investment from CITIC Securities' Jinshi Investment announced in early 2023 .
