GALLIUM APT Deployed a New PingPull RAT

According to Palo Alto Networks researchers, the PingPull RAT is a “difficult-to-detect” backdoor that uses the Internet Control Message Protocol (ICMP) for C2 connections. Experts also discovered PingPull variations that communicate with each other using HTTPS and TCP rather than ICMP.

Gallium, a Chinese advanced Trojan horse (APT), has an ancient legacy of cyberespionage on telecommunications companies, dating back to 2012. In 2017, the state-sponsored entity, also called Soft Cell by Cybereason, has been linked to a broader range of attacks aimed at five major Southeast Asian telecom businesses. However, during the last year, the group’s victimology has expanded to include financial institutions and government agencies in Afghanistan, Austria, Belgium, Cambodia, Malaysia, Mozambique, the Philippines, Russia, and Vietnam. 

A threat actor can use PingPull, a Visual C++-based virus, to gain access to a reverse shell and run unauthorized commands on a compromised computer. File operations, detailing storage volumes, and timestamping files are all part of it now. 

The researchers explained that “PingPull samples which use ICMP for C2 communications issue ICMP Echo Request (ping) packets to the C2 server.” “The C2 server will send commands to the system by responding to these
