T1625.001: System Runtime API Hijacking

Adversaries may execute their own malicious payloads by hijacking the way an operating system runs applications. Hijacking execution flow can be for the purposes of persistence since this hijacked execution may reoccur at later points in time.

On Android, adversaries may overwrite the standard OS API library with a malicious alternative to hook into core functions to achieve persistence. By doing this, the adversary’s code will be executed every time the overwritten API function is called by an app on the infected device.

Executive priority

T1625.001: System Runtime API Hijacking is an official MITRE ATT&CK technique. 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 T1625.001: System Runtime API Hijacking by reviewing the official ATT&CK relationships, mapped tactics (persistence), supported platforms (Android), and available local telemetry before making detection or mitigation decisions.

Likely telemetry

  • Official ATT&CK relationships and object metadata
  • Identity, privilege, and authentication events

Detection direction

  • Validate whether T1625.001: System Runtime API Hijacking 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.
