<p>Creation or modification of files in directories known to be excluded from AV scanning (e.g., C:\Windows\Temp, Exchange server directories, or default AV exclusions). Defender perspective: correlate file creation with execution behavior or anomalous parent processes writing to excluded paths.</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=11 | DC0039 File Creation |
| WinEventLog:Security | EventCode=4663, 4670, 4656 | DC0055 File Access |
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 |
|---|---|
ExcludedPaths | List of directories excluded from scanning in the environment (customizable per organization). |
ProcessAllowlist | Legitimate processes typically writing to excluded paths to minimize false positives. |
