Windows · attack.mitre.org · ATT&CK Enterprise v19.2
<p>Detects adversarial archiving of files prior to exfiltration by correlating execution of compression/encryption utilities (e.g., makecab.exe, rar.exe, 7z.exe, powershell Compress-Archive) with subsequent creation of large compressed or encrypted files. Identifies abnormal process lineage involving crypt32.dll usage, command-line arguments invoking compression switches, and file write operations to temporary or staging 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:Security | EventCode=4688 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=7 | DC0016 Module Load |
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 |
|---|---|
ArchiveExtensions | List of file extensions treated as suspicious when created outside of expected paths. |
ProcessAllowlist | Known business processes permitted to use compression/encryption utilities. |
FileSizeThresholdMB | Minimum file size for flagging archive creation to reduce noise from benign small compressions. |
