What it detects

This rule flags process creation events where cmd.exe executes built-in del or erase commands to delete files. File deletion can help attackers remove artifacts created during intrusion activity or post-intrusion cleanup to reduce observable traces. The detection relies on Windows process creation telemetry, matching cmd.exe execution along with del/erase command-line substrings and optional flags such as -f, -s, and -q.
