DET0146 Detection of Data Destruction Across Platforms via Mass Overwrite and Deletion Patterns

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
CommandPatternFocus on high-risk patterns in temporary directories or key system paths.
EntropyChangeRateOptional anomaly detection on overwritten files with high-entropy payloads.
