S0059: WinMM describes [WinMM](https://attack.mitre.org/software/S0059) is a full-featured, simple backdoor used by [Naikon](https://attack.mitre.org/groups/G0019). (Citation: Baumgartner Naikon 2015)

Executive priority

S0059: WinMM is an official MITRE ATT&CK software. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.

Technical view

Security teams should validate S0059: WinMM by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (Windows), and available local telemetry before making detection or mitigation decisions.

Likely telemetry

  • Official ATT&CK relationships and object metadata
  • Network, endpoint, and security-tool telemetry

Detection direction

  • Validate whether S0059: WinMM appears in your detection coverage and tabletop scenarios.
  • Use the object to align executive risk language with SOC, incident response, and detection engineering work.
  • Do not treat ATT&CK relationship context as attribution without corroborating evidence.

Mitigation priorities

  • Map the object to existing controls and identify missing telemetry or response ownership.
  • Prioritize mitigations that reduce exposure on the listed platforms and tactics.
  • Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits

Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.

This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

Generated from the cited source records. This long-tail analysis has not been individually reviewed by a named human.

Treat this object as behavior context, not an attribution claim. Validate the related groups, software, data sources, and mitigations against official ATT&CK relationships and your own telemetry before making control-coverage decisions.

ATT&CK relationship table

Techniques used

This mirrors the MITRE pattern of making group, software, campaign, and technique relationships scannable. Relationship notes come from mirrored ATT&CK relationship text when available.

6 rows
DomainIDNameRelationship / procedure
EnterpriseT1057Process Discovery

WinMM sets a WH_CBT Windows hook to collect information on process creation.[1]

EnterpriseT1083File and Directory Discovery

WinMM sets a WH_CBT Windows hook to search for and capture files on the victim.[1]

EnterpriseT1082System Information Discovery

WinMM collects the system name, OS version including service pack, and system install date and sends the information to the C2 server.[1]

EnterpriseT1008Fallback Channels

WinMM is usually configured with primary and backup domains for C2 communications.[1]

EnterpriseT1071.001Web ProtocolsSub-technique

WinMM uses HTTP for C2.[1]

EnterpriseT1033System Owner/User Discovery

WinMM uses NetUser-GetInfo to identify that it is running under an “Admin” account on the local system.[1]

G0019: Naikon

Naikon is assessed to be a state-sponsored cyber espionage group attributed to the Chinese People’s Liberation Army’s (PLA) Chengdu Military Region Second Technical Reconnaissance Bureau (Military Unit Cover Designator 78020).[1] Active since at least 2010, Naikon has primarily conducted operations against government, military, and civil organizations in Southeast Asia, as well as against international bodies such as the United Nations Development Programme (UNDP) and the Association of Southeast Asian Nations (ASEAN).[1][2]

While Naikon shares some characteristics with APT30, the two groups do not appear to be exact matches.[3]
