Detecting Living-off-the-Land Attacks in OT Networks

This report enumerates malicious TTPs observed in post-compromise activity: encoded PowerShell execution, WMI-based remote execution, scheduled-task persistence, credential extraction via Volume Shadow Copy/NTDS.dit access, fileless in-memory execution, and event-log clearing — several of which are attributed to Volt Typhoon and VOLTZITE. The focus is on detection-evasion techniques and native-tool misuse enabling persistence, credential theft, and forensic anti-analysis.
