TA0003 · PERSISTENCE
Create or Modify System Process
Windows services, launch daemons, and systemd units created or hijacked for persistence.
Detect it with
Event ID 7045; new unit files in /etc/systemd/system; service binaries in unusual paths.
Why it matters on shift
Create or Modify System Process is one of the concrete ways adversaries achieve persistence. Recognising it in telemetry lets you name the technique in your ticket and pivot to what came before and after.
What to look for next
After persistence, the next tactic is usually Privilege Escalation. Search your telemetry for the transition before closing the ticket.
5 sub-techniques
How it shows up in practice
- T1543.001
Launch Agent
Adversaries may create or modify launch agents to repeatedly execute malicious payloads as part of persistence.
- T1543.002
Systemd Service
Adversaries may create or modify systemd services to repeatedly execute malicious payloads as part of persistence.
- T1543.003
Windows Service
Adversaries may create or modify Windows services to repeatedly execute malicious payloads as part of persistence. When Windows boots up, it starts programs or applications called services that perform background system functions.
- T1543.004
Launch Daemon
Adversaries may create or modify Launch Daemons to execute malicious payloads as part of persistence. Launch Daemons are plist files used to interact with Launchd, the service management framework used by macOS.
- T1543.005
Container Service
Adversaries may create or modify container or container cluster management tools that run as daemons, agents, or services on individual hosts.
