Kothamine hidden PowerShell adds Defender exclusion for artifact paths
Detects the use of PowerShell to add an exclusion to Microsoft Defender. The detection looks for common obfuscation flags (Hidden, NonI, NoP, Bypass) in the command line and targets the MicrosoftEdgeUpdateCore executable or DLL for exclusion, which is a common persistence or evasion technique. It excludes parent processes known for administrative activity to reduce noise.
