What it detects

This rule detects ProcDump invoked with the accept eula and full memory dump flags which the NetSupport actor used through a renamed binary to capture process memory including LSASS and this matters because full memory dumps of running processes are a common credential access technique and the renamed binary reflects deliberate evasion of image name detections.
