<p>Processes invoking destructive commands (dd, shred, wipe) with raw device targets (e.g., /dev/sda, /dev/nvme0n1). Detect direct writes to disk partitions and abnormal superblock or bootloader modifications. Correlate shell execution with subsequent block device I/O.</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
TargetDevicesTune to exclude removable drives or test partitions commonly written by administrators.
EntropyThresholdDetects large blocks of pseudorandom data being written; may need tuning for backup/crypto workloads.
