Who they are
MITRE ATT&CK describes Mustang Panda as a China-based cyber espionage threat actor operating since at least 2012. The US Department of Justice, citing court documents on 14 January 2025, says the PRC government paid the group to develop a version of PlugX. CERT-EU calls it China-linked.
Who they target
MITRE lists government, diplomatic and non-governmental organizations, think tanks, religious institutions and research bodies in the US, Europe and Asia. Justice adds Chinese dissident groups. The CISA-led guidance adds activist groups.
How they usually get in
Phishing emails with decoy documents, archives or links. MITRE says a signed program then loads a malicious DLL to install tools such as PlugX. ENISA and CERT-EU also list watering hole attacks and infected USB drives.
What stands out
The US took court-authorized action against one PlugX variant it ties to the group, deleting it from approximately 4,258 US computers. MITRE says a customized PlugX variant could spread over USB and take documents from air-gapped networks.
What to do first
Keep software updated and use phishing-resistant multifactor authentication. Then train staff to spot decoy documents and archives, and limit USB and removable media use.
Names
Public reports use several names for this activity.

US Department of Justice14 January 2025
Said a group of hackers sponsored by the PRC, known to the private sector as Mustang Panda and Twill Typhoon, used a version of PlugX, and that court documents say the PRC government paid the group to develop it.[3]
FBI (affidavit)unsealed with the 14 January 2025 announcement
Stated that it assesses Mustang Panda takes payment from the Chinese government in exchange for providing malware, including PlugX, and other computer intrusion services.[4]

Where sources differ
Sources differ on the start year. MITRE ATT&CK says the group has operated since at least 2012. The US Department of Justice affidavit says China-based state-sponsored hackers have used PlugX since at least 2014. ENISA and CERT-EU say the group was first observed in 2017 and has possibly been operating since at least 2014.
Sources also differ in strength on who stands behind it. MITRE says China-based. CERT-EU says China-linked and, in 2023, repeated that commercial firms indicated it likely operates from Chinese territory. The US Department of Justice goes further: citing court documents, it says the PRC government paid the group to develop a version of PlugX, and the FBI says it assesses the group takes payment from the Chinese government. No source opened names a specific Chinese agency.

How they get in
Techniques reported for this group, by MITRE ATT&CK tactic.
MITRE says the group used spearphishing attachments to deliver initial payloads, and the CISA-led guidance names spearphishing as its preferred way in.[1, 5]
Install updates promptly and set up phishing-resistant multifactor authentication, as the joint guidance lists first. The FBI also urges anti-virus and security updates to prevent reinfection by PlugX.
Run basic training on account phishing, email and web browsing security, including decoy documents and archive files that open a harmless document while something else runs.
Help the diplomats, researchers and senior staff who get targeted emails to spot lures built around their work.
