Linux · attack.mitre.org · ATT&CK Enterprise v19.2
<p>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.</p>

Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| auditd:SYSCALL | fork/clone/daemon syscall tracing | DC0021 OS API Execution |
| auditd:SYSCALL | execve of re-parented process | DC0032 Process Creation |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
TimeWindow | Maximum time between parent and child process creation and parent process termination |
ReparentingDetectionScope | Scope for detecting unexpected re-parenting to init/systemd |
ExecutableScope | Subset of monitored executables or services likely to abuse double-fork |
