<p>Use of nohup, disown, or AppleScript constructs to suppress process interrupts. Defender perspective: commands containing nohup or hidden background tasks (
osascript with persistent execution) correlated with processes surviving user logouts.</p>- Detects

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 |
|---|---|---|
| macos:unifiedlog | nohup, disown, or osascript execution patterns | DC0064 Command Execution |
| macos:unifiedlog | background process persists beyond user logout | 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 |
|---|---|
WatchedShells | Shells or interpreters where nohup/disown usage is suspicious, configurable to environment. |
PersistenceCorrelationWindow | Time window to correlate process continuation after logout with suspicious commands. |
