<p>Adversary spawns command-line tools (e.g., del, cipher /w, SDelete) or scripts to recursively delete or overwrite user/system files. This may be correlated with abnormal file IO activity, registry writes, or tampering in critical system directories.</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 |
|---|---|---|
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=23 | DC0040 File Deletion |
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 |
|---|---|
TargetFilename | Filter file deletion activity to sensitive locations (e.g., %System32%, Documents, DB paths). |
ProcessCommandLine | Tune for aggressive overwrite flags (e.g., /w, /q, /s) or temp file overwrites. |
VolumeThreshold | Threshold of unique file deletions or modifications within time window. |
TimeWindow | Correlate rapid file delete/overwrite behavior from same process/user. |
