Injecting a DLL into Modern UI (aka Metro/Windows-App) App

Looks like Microsoft did learn (at least a little) the lesson from Sidebar Gadgets

When you try to inject a library into a Windows 8 Modern UI Metro application you will find that although the injection code works as expected, your DLL will NOT load, LoadLibrary will return FALSE and GetLastError will return ERROR_ACCESS_DENIED.

As Far as I can tell they failed to achieve what they were attempting maybe some more technical person may be able to read more into this (like Alan or Keetah)

Sidebar gadgets weren't vulnerable to DLL injections. They had cross site scripting issues that are a whole different beast.

The only thing Microsoft have achieved here is isolating processes in the modern UI, so that additional code can't be loaded into them and forced to run. A program attempting to do so will not crash, but rather be sent a passive aggressive "you can't do that!" message.

Of course, only an executable can inject code into another program. For this situation to occur the system is likely already compromised.

thanks, good explanation.
