Detects the creation of a scheduled task intended to masquerade as 'MicrosoftEdgeUpdateTask' using either schtasks.exe or PowerShell. The rule specifically monitors for tasks being registered in AppData/Roaming directories, which is a common indicator of persistence by malicious actors attempting to mimic legitimate Microsoft Edge update processes.

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.
