Windows · attack.mitre.org · ATT&CK Enterprise v19.2

<p>Detects adversarial archiving using built-in or third-party utilities (makecab, diantz, xcopy, certutil, 7z, WinRAR, WinZip). Correlates suspicious process creation events with command-line arguments for compression/encoding, followed by creation of archive files (.cab, .zip, .7z, .rar). Identifies anomalous loading of crypt32.dll for encryption operations or execution of diantz.exe to compress remotely staged files.</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.

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.

FieldDescription
SuspiciousExtensionsList of archive extensions considered high risk (.cab, .zip, .7z, .rar).
ProcessAllowlistKnown business utilities allowed to create archives without alerting.
FileSizeThresholdMBMinimum archive size threshold to filter out benign small compressions.
