Module Name:
|
||
|
|
|
||
|
|
SuperChix76.cpp
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
Hook LoadLibrary and calls GetDeviceIdentifier which initializes wintrust.
|
||
|
|
|
||
|
|
This fixes the problem whereby the app will hang if they call
|
||
|
|
GetDeviceIdentifier from within a DllMain - which is an app bug.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.
