Executive priority

S0182: FinFisher 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 S0182: FinFisher by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (Windows, Android), 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 S0182: FinFisher 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.

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.

22 rows
DomainIDNameRelationship / procedure
EnterpriseT1134.001Token Impersonation/TheftSub-technique

FinFisher uses token manipulation with NtFilterToken as part of UAC bypass.[1][5]

EnterpriseT1113Screen Capture

FinFisher takes a screenshot of the screen and displays it on top of all other windows for few seconds in an apparent attempt to hide some messages showed by the system during the setup process.[1][5]

EnterpriseT1547.001Registry Run Keys / Startup FolderSub-technique

FinFisher establishes persistence by creating the Registry key HKCU\Software\Microsoft\Windows\Run.[1][5]

EnterpriseT1685.005Clear Windows Event LogsSub-technique

FinFisher clears the system event logs using OpenEventLog/ClearEventLog APIs .[1][5]

EnterpriseT1497.001System ChecksSub-technique

FinFisher obtains the hardware device list and checks if the MD5 of the vendor ID is equal to a predefined list in order to check for sandbox/virtualized environments.[5]

EnterpriseT1574.001DLLSub-technique

FinFisher uses DLL side-loading to load malicious programs.[1][5] A FinFisher variant also uses DLL search order hijacking.[1][4]

FinFisher injects itself into various processes depending on whether it is low integrity or high integrity.[1][5]

EnterpriseT1548.002Bypass User Account ControlSub-technique

FinFisher performs UAC bypass.[1][5]

EnterpriseT1083File and Directory Discovery

FinFisher enumerates directories and scans for certain files.[1][5]

FinFisher creates a new Windows service with the malicious executable for persistence.[1][5]

EnterpriseT1027.016Junk Code InsertionSub-technique

FinFisher contains junk code in its functions in an effort to confuse disassembly programs.[1][5]

EnterpriseT1036.005Match Legitimate Resource Name or LocationSub-technique

FinFisher renames one of its .dll files to uxtheme.dll in an apparent attempt to masquerade as a legitimate file.[1][5]

EnterpriseT1140Deobfuscate/Decode Files or Information

FinFisher extracts and decrypts stage 3 malware, which is stored in encrypted resources.[1][5]

EnterpriseT1057Process Discovery

FinFisher checks its parent process for indications that it is running in a sandbox setup.[1][5]

FinFisher probes the system to check for antimalware processes.[1][4]

EnterpriseT1082System Information Discovery

FinFisher checks if the victim OS is 32 or 64-bit.[1][5]

EnterpriseT1027Obfuscated Files or Information

FinFisher is heavily obfuscated in many ways, including through the use of spaghetti code in its functions in an effort to confuse disassembly programs. It also uses a custom XOR algorithm to obfuscate code.[1][5]

EnterpriseT1574.013KernelCallbackTableSub-technique

FinFisher has used the KernelCallbackTable to hijack the execution flow of a process by replacing the __fnDWORD function with the address of a created Asynchronous Procedure Call stub routine.CitationFinFisher exposed
