Unusual Windows Path Activity

Unusual Windows Path Activity

edit

Identifies processes started from atypical folders in the file system, which may indicate malware execution or persistence mechanisms. In corporate Windows environments, software installation is centrally managed and it is unusual for programs to be executed from user or temporary directories. Processes executed from these locations can denote that a user downloaded software directly from the Internet or a malicious script or macro executed malware.
