<p>Detects suspicious custom compression/encryption routines through anomalous script or binary execution that produces high-entropy files without standard archiving utilities. Correlates script execution, memory API usage (bitwise ops, CryptoAPI calls), and creation of archive-like files with uncommon headers.</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:Security | EventCode=4688 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=10 | DC0035 Process 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 |
|---|---|
EntropyThreshold | Minimum entropy level that flags suspicious custom archives. |
AllowedProcesses | Known business processes performing encryption or compression. |
TimeWindow | Correlation timeframe between script execution and file creation. |
