title: Suspicious Use of Procdump
id: 5afee48e-67dd-4e03-a783-f74259dcf998
description: Detects suspicious uses of the SysInternals Procdump utility by using a special command line parameter in combination with the lsass.exe process. This way we're also able to catch cases in which the attacker has renamed the procdump executable.
