Thanks! :) The threat actor social engineering attacks are targeting normal business users, uers with role are technical in nature and tend not to follow these type of instruction, hence I exclude this group of privilege roles users.

PowerShell Self-Pwn Detection

Proofpoint highlights a social engineering tactic where users are tricked into running malicious PowerShell scripts, leading to malware infections. Despite needing user interaction, the attack's success relies on clever social engineering.

In AD environments, Timeroasting exploits NTP authentication to request password hashes of computer/trust accounts. If non-standard or legacy passwords are used, offline brute-forcing is possible. I've created a KQL query to detect such activities. #KQL #Timeroast
