Overview

In our last Memory Forensics Skillbuilder webcast (https://t.co/xZjSMoi9Sc), we used WinDbg to examine a user-mode process dump and recover contents of heap memory. A fantastic use case for data recovery and activity reconstruction. But picture this scenario: your SOC alerts you that suspicious files were found on one of your domain controllers, to include lsass.dmp. Knowing attackers love user-mode process dumps too, we suspect this may be evidence of credential harvesting. In this second episode of MFS, we use WinDbg to identify in-memory patching and enumerate compromised credentials, all from this rogue lsass.dmp.
