Updated Date: 2026-05-13 ID: 30874d4f-20a1-488f-85ec-5d52ef74e3f9 Author: Bhavin Patel, Splunk Product: Splunk Enterprise Security

Description

Monitor for activities and techniques associated with maintaining persistence on a Windows system--a sign that an adversary may have compromised your environment.

Why it matters

Maintaining persistence is one of the first steps taken by attackers after the initial compromise. Attackers leverage various custom and built-in tools to ensure survivability and persistent access within a compromised enterprise. This Analytic Story provides searches to help you identify various behaviors used by attackers to maintain persistent access to a Windows environment.
