In one minute

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.

Who says so

Attribution is a judgment by the body named. It is shown here as attributed, not as proven fact.

  • MITRE ATT&CK page modified 31 July 2026

    Describes Mustang Panda as a China-based cyber espionage threat actor that has been conducting operations since at least 2012.[1]

  • ENISA and CERT-EU 15 February 2023

    Said commercial firms indicated that Mustang Panda is likely operating from the territory of China, and that recent operations of the six named groups focused mainly on information theft.[8]

  • CISA, FBI and partner agencies 14 May 2024

    Describe Mustang Panda as a group affiliated with the PRC that focuses on political espionage. The Canadian Cyber Centre and Japan's National Police Agency published the same text.[5, 6, 7]

  • CERT-EU February 2024

    Said Mustang Panda is attributed by reliable sources to China, in its yearly threat report for 2023.[9]

  • US Department of Justice 14 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]

  • CERT-EU 3 February 2025

    Described PlugX as allegedly deployed by China-backed hackers Mustang Panda and Twill Typhoon, when reporting the Justice Department announcement.[13]

  • CERT-EU 1 July 2026

    Called the group China-linked and described a June 2026 phishing campaign as possible, not confirmed.[14]

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.

Who does it target?

MITRE lists government, diplomatic and non-governmental organizations, think tanks, religious institutions and research bodies in the US, Europe and Asia. The Justice Department adds Chinese dissident groups, and the CISA-led guidance adds activist groups.

How does it get in?

MITRE and the CISA-led guidance describe phishing emails with decoy documents, archives or links, then a signed program that loads a malicious DLL. ENISA and CERT-EU also list watering hole attacks and infected USB drives.
