Chinese Hackers Use DNS-over-HTTPS for Linux Malware Communication

The particular threat actor was first documented back in September 2021 by Positive Technologies; however, the researchers only focused on the Windows toolkit.

A report published yesterday by Stairwell and shared with BleepingComputer describes a new Linux implant written in C++ that expands the threat actor's intrusion arsenal and, by extension, the attackers' indicators of compromise.

The link between ChamelGang and the new Linux malware is based on a domain previously associated with the threat actor and a custom privilege elevation tool observed by Positive Technologies in past ChamelGang campaigns.
