Abstract

Techniques for replacing ROM-based (Read-Only Memory) DLLs (Dynamic Link Libraries) in a Windows CE type embedded operating system such that the target DLL is replaceable by the hook DLL, and the target DLL is callable by the hook DLL but not callable directly by any other applications after loading of the hook DLL. The techniques enable replacement irrespective whether the hook DLL and the target DLL have the same name and irrespective of which DLL is loaded first. The techniques change the file name of the target DLL in a list of loaded DLL modules by a trusted program that executes in the full kernel mode.
