/*++ Copyright (c) 2000 Microsoft Corporation Module Name: HighVersionLie.cpp Abstract: This DLL hooks GetVersion and GetVersionEx so that they return a future OS version credentials. Notes: This is a general purpose shim. History: 02/08/2001 clupu Created 09/21/2001 rparsons Added VLOG on hooks per billshih. 10/17/2001 rparsons Fixed bugs in GetVersionExW and GetVersion. 11/27/2001 rparsons Modified the VLOGs so they display what we used for the API call. --*/ #include "precomp.h" IMPLEMENT_SHIM_BEGIN(HighVersionLie) #include "ShimHookMacro.h" BEGIN_DEFINE_VERIFIER_LOG(HighVersionLie) VERIFIER_LOG_ENTRY(VLOG_HIGHVERSION_GETVERSION) VERIFIER_LOG_ENTRY(VLOG_HIGHVERSION_GETVERSIONEX) END_DEFINE_VERIFIER_LOG(HighVersionLie) INIT_VERIFIER_LOG(HighVersionLie); APIHOOK_ENUM_BEGIN APIHOOK_ENUM_ENTRY(GetVersionExA) APIHOOK_ENUM_ENTRY(GetVersionExW) APIHOOK_ENUM_ENTRY(GetVersion) APIHOOK_ENUM_END DWORD g_dwMajorVersion; DWORD g_dwMinorVersion; DWORD g_dwBuildNumber; BOOL APIHOOK(GetVersionExA)( OUT LPOSVERSIONINFOA lpVersionInformation ) { BOOL bReturn = FALSE; if (ORIGINAL_API(GetVersionExA)(lpVersionInformation)) { LOGN(eDbgLevelInfo, "[GetVersionExA] called.
