Rewterz Threat Alert – Double Dragon APT41, a Dual Espionage and Cyber Crime Operation

Severity

High

Analysis Summary

APT41 espionage operations against the healthcare, high-tech, and telecommunications sectors include establishing and maintaining strategic access, and through mid-2015, the theft of intellectual property.

APT41 is unique among tracked China-based actors in that it leverages non-public malware typically reserved for espionage operations in what appears to be activity that falls outside the scope of state-sponsored missions. Based on early observed activity, consistent behavior, and APT41’s unusual focus on the video game industry, we believe the group’s cyber crime activities are most likely motivated by personal financial gain or hobbyist interests.

Impact

Financial loss
