Deprecated - Process Termination followed by Deletion

Last updated 14 days ago on 2025-12-11

About

Identifies a process termination event quickly followed by the deletion of its executable file. Malware tools and other non-native files dropped or created on a system by an adversary may leave traces to indicate to what occurred. Removal of these files can occur during an intrusion, or as part of a post-intrusion process to minimize the adversary's footprint.
