A China-backed crime ring tagged Bronze President launched a campaign targeting government officials in Europe, the Middle East, and South America leveraging PlugX malware – the backdoor popular among Chinese hacker gangs.
According to the researchers, the major objective of the threat group is espionage.
SOC Prime delivers Threat Hunting & Cyber Threat Intelligence for accelerated SOC operations, leveraging the benefits of a code-driven approach for scalable and effective security practices. The following Sigma-based rules released by SOC Prime’s Threat Bounty developers Wirapong Petshagun and Zaw Min Htun (ZETA) help security practitioners detect whether the systems were exposed to PlugX malware:
The detections are available for 26+ SIEM, EDR & XDR platforms, aligned with the MITRE ATT&CK® framework v.10.

The Bronze President criminal hacker group, aka Mustang Panda, HoneyMyte, Red Lich, Temp.Hex., TA416, and RedDelta, use closed- and open-source malicious software to compromise entities in a wide array of industry sectors since 2018. Among the tools that the threat actors use are both legitimate and malicious software such as Cobalt Strike, China Chopper, ORat, and RCSession.
The cluster’s Modus operandi suggests that it is either merely tolerated by the Chinese government or even tasked by it.
In Spring 2022, threat analysts from ESET released a detailed write-up on the cyberespionage campaign carried out by the Bronze President. The threat group used one of the PlugX versions tagged Hodur in attacks across East and Southeast Asia, Europe, and Africa, spreading it in a spear-phishing campaign.
The most recent campaign is characterized by the introduction of RAR archive files to distribute malware. When the victim opens a weaponized RAR file, a Windows shortcut (LNK) file that looks like a document is shown. Clicking on this “file” will execute the malware. The attacks were documented in June and July 2022.
