Briefing

A server’s EDR agent stopped reporting an hour ago. The image is cases/app-07/app-07.mem. On a healthy Windows host there is exactly one lsass.exe, a child of wininit.exe, running from System32.

windows.pstree prints the process tree with asterisks for depth, plus each process’s command line and image path.
