What it detects

This rule identifies execution of the Dumpert process dumper by matching a known Dumpert.dll string in the command line or a specific MD5 hash. Dumping process memory is commonly used to access credentials, including from lsass.exe. It relies on Windows process creation telemetry with command-line content and process image hash values.
