    Home security reminder. A lot of people are going away for Christmas which makes their homes easy pickings for burglars. For security reasons I strongly recommend leaving one of your children behind to construct a series of elaborate booby traps and defend your interests.

    Published part 1 of a short series on AppLocker internals, no bypasses, just how the technology actually works on Windows 10 1909 and maybe some silly tricks along the way.

    Released to go with my talk, a project which contains a C# client for almost every ALPC RPC server on Windows 7 through Windows 10 1909. Could be useful for EoP research, fuzzing etc.
