What it detects
This rule detects a full memory dump of lsass.exe requested on the command line which APT41 performs with procdump to extract cleartext credentials and hashes. The dumped process memory is exfiltrated and parsed offline with Mimikatz. Detecting it exposes an active credential theft attempt against the LSA subsystem.
