Iron Group is an advanced persistent threat (APT) actor first observed in late 2016 or early 2017, widely believed to be state-sponsored and operating from China. While the group possesses capabilities consistent with cyber-espionage and data theft, their operational history predominantly reveals a focus on financially motivated cybercrime, particularly through cryptocurrency mining and ransomware deployment. This dual operational nature, combining state-sponsored backing with cybercrime-for-profit activities, distinguishes Iron Group. They are also known by the aliases Iron Cyber Group and Rocke. Their activities have included deploying a variety of malware to infect systems across multiple platforms, engaging in large-scale cryptojacking operations, and using destructive malware disguised as ransomware for data exfiltration and deletion.
