[QUOTE="Andy Ful, post: 625958, member: 32260"] I did some tests with fake PowerShell executable known as 'p0wnedShell'. I compiled it including original System.Management.Automation.dll . Tests were done with active default deny SRP to force ConstrainedLanguage mode. So, I copied original powershel.exe and custom made p0wnedShell.exe into whitelisted folder and run as standard user. [LIST=1] [*]The executable p0wnedShell.exe worked in FullLanguage mode, while powershell.exe worked in ConstrainedLanguage mode. [*]Both executables respected Registry settings: ExecutionPolicy and EnableScripts. [/LIST] So, the custom made executable, can bypass Language mode, but probably cannot bypass so easy, EnableScripts registry tweak. The Language mode solutions require original powershell.exe to work properly. [/QUOTE]
