What it detects

This rule detects Task Manager being used to create a memory dump of the LSASS process, matching credential access observed after Ivanti appliance exploitation by Unit 42. Adversaries dump LSASS through the built-in Taskmgr interface to harvest credentials while avoiding known dumping tools which enables further lateral movement.
