What it detects

This rule detects cmd.exe running host and network reconnaissance commands with output redirected to a temporary rad file, a collection pattern used by RansomHub affiliates staging SocGholish activity. Piping discovery command results into a randomized rad.tmp file for later exfiltration is an early hands-on-keyboard indicator.
