What it detects

This rule flags process executions where python.exe is used to run a command line containing adidnsdump. Adidnsdump is used to enumerate or export DNS records, which can support reconnaissance of internal Active Directory integrated DNS. The detection relies on process creation telemetry including the image path and command line string contents.
