S0533: SLOTHFULMEDIA

SLOTHFULMEDIA is a remote access Trojan written in C++ that has been used by an unidentified "sophisticated cyber actor" since at least January 2017.[1][2] It has been used to target government organizations, defense contractors, universities, and energy companies in Russia, India, Kazakhstan, Kyrgyzstan, Malaysia, Ukraine, and Eastern Europe.[3][4]

In October 2020, Kaspersky Labs assessed SLOTHFULMEDIA is part of an activity cluster it refers to as "IAmTheKing".[4] ESET also noted code similarity between SLOTHFULMEDIA and droppers used by a group it refers to as "PowerPool".[5]

Executive priority

S0533: SLOTHFULMEDIA 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 S0533: SLOTHFULMEDIA 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 S0533: SLOTHFULMEDIA 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.
