S0168: Gazer describes [Gazer](https://attack.mitre.org/software/S0168) is a backdoor used by [Turla](https://attack.mitre.org/groups/G0010) since at least 2016. (Citation: ESET Gazer Aug 2017)

Executive priority

S0168: Gazer 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 S0168: Gazer 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 S0168: Gazer 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.

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.

18 rows
DomainIDNameRelationship / procedure
EnterpriseT1547.004Winlogon Helper DLLSub-technique

Gazer can establish persistence by setting the value “Shell” with “explorer.exe, %malware_pathfile%” under the Registry key HKCU\Software\Microsoft\Windows NT\CurrentVersion\Winlogon.[1]

EnterpriseT1070.006TimestompSub-technique

For early Gazer versions, the compilation timestamp was faked.[1]

EnterpriseT1573.002Asymmetric CryptographySub-technique

Gazer uses custom encryption for C2 that uses RSA.[1][2]

EnterpriseT1547.001Registry Run Keys / Startup FolderSub-technique

Gazer can establish persistence by creating a .lnk file in the Start menu.[1][2]

EnterpriseT1071.001Web ProtocolsSub-technique

Gazer communicates with its C2 servers over HTTP.[1]

EnterpriseT1547.009Shortcut ModificationSub-technique

Gazer can establish persistence by creating a .lnk file in the Start menu or by modifying existing .lnk files to execute the malware through cmd.exe.[1][2]

EnterpriseT1070.004File DeletionSub-technique

Gazer has commands to delete files and persistence mechanisms from the victim.[1][2]

EnterpriseT1055.003Thread Execution HijackingSub-technique

Gazer performs thread execution hijacking to inject its orchestrator into a running thread from a remote process.[1][2]

EnterpriseT1055Process Injection

Gazer injects its communication module into an Internet accessible process through which it performs C2.[1][2]

EnterpriseT1105Ingress Tool Transfer

Gazer can execute a task to download a file.[1][2]

EnterpriseT1573.001Symmetric CryptographySub-technique

Gazer uses custom encryption for C2 that uses 3DES.[1][2]

EnterpriseT1546.002ScreensaverSub-technique

Gazer can establish persistence through the system screensaver by configuring it to execute the malware.[1]

EnterpriseT1553.002Code SigningSub-technique

Gazer versions are signed with various valid certificates; one was likely faked and issued by Comodo for "Solid Loop Ltd," and another was issued for "Ultimate Computer Support Ltd."[1][2]

EnterpriseT1033System Owner/User Discovery

Gazer obtains the current user's security identifier.[2]

EnterpriseT1564.004NTFS File AttributesSub-technique

Gazer stores configuration items in alternate data streams (ADSs) if the Registry is not accessible.[1]

EnterpriseT1027.013Encrypted/Encoded FileSub-technique

Gazer logs its actions into files that are encrypted with 3DES. It also uses RSA to encrypt resources.[2]

EnterpriseT1053.005Scheduled TaskSub-technique

Gazer can establish persistence by creating a scheduled task.[1][2]

EnterpriseT1480.002Mutual ExclusionSub-technique

Gazer creates a mutex using the hard-coded value `{531511FA-190D-5D85-8A4A-279F2F592CC7}` to ensure that only one instance of itself is running.[1]

G0010: Turla

Turla is a cyber espionage threat group that has been attributed to Russia's Federal Security Service (FSB). They have compromised victims in over 50 countries since at least 2004, spanning a range of industries including government, embassies, military, education, research and pharmaceutical companies. Turla is known for conducting watering hole and spearphishing campaigns, and leveraging in-house tools and malware, such as Uroburos.[1][2][3][4][5]
