Break Process Trees

An adversary may attempt to evade process tree-based analysis by modifying executed malware's parent process ID (PPID). If endpoint protection software leverages the “parent-child" relationship for detection, breaking this relationship could result in the adversary’s behavior not being associated with previous process tree activity.

how MITRE says to see it

Detection Strategy for Masquerading via Breaking Process Trees

  • Detects anomalous process execution patterns where a process's parent terminates quickly after process creation or is re-parented to 'init' (PID 1), often indicating double-fork or daemon-style detachment. These behaviors sever the parent-child relationship and obscure the execution origin in process tree analysis.
  • Detects execution patterns where a child process is detached from its original parent, often showing up under 'launchd' (PID 1) with no parent lineage. These breakages in the process tree are indicative of evasive techniques using `daemon()`, `fork()` or background execution flags.
