Winmine_XP.exe 코드 분석

|
By UINT Msg, WPARAM wParam
| velog.io
IDA는 실행파일을 기계어에서 사람이 읽을 수 있는 형태로 바꿔주는 도구이다. 이 IDA를 이용해 Winmine_XP.exe를 분석하겠다. IDA에 해당 실행 파일을 넣으면 다음과 같은 Graph View를 볼 수 있다. *Graph View: 함수 흐름을 블록 단위 그래프로 보여줌 F5를 눌러 디컴파일하면 다음과 같은 101줄의 코드로 변환되었다.

findKey shift + f12 找到一个flag{}字符串, 定位到关键函数, F5无效, 大概率是有花指令, 读一下汇编 这里连续push两个byte_428C54很奇怪, nop掉下面那个, 再往上找到函数入口, p设置函数入口, 再F5 LRESULT __stdcall sub_401640(HWND hWndParent, UINT Msg, WPARAM wParam, LPARAM lParam) { int v5; size_t v6; DWORD v7; int v8; int v9; CHAR *v10; CHAR v11[256]; char v12[7]; __int16 v13; char v14; char Str[253]; __int16 v16; char v17; CHAR v18[256]; CHAR String[4]; int v20; __int16 v21; CHAR Text[32]; struct tagRECT Rect; CHAR Buffer[100]; HDC hdc; struct tagPAINTSTRUCT...

进程的通信 - WM_COPYDATA

|
By WPARAM wParam, LPARAM lParam, UINT Msg
| CSDN
在Windows程序中，各个进程之间常常需要交换数据，进行数据通讯。其中使用SendMessage向另一进程发送WM_COPYDATA消息是一种比较经济实惠的方法。 WM_COPYDATA通信需要将传递的消息封装在COPYDATASTRUCT结构体中，在SendMessage消息传递函数时作为lParam参数传递 COPYDATASTRUCT的结构如下： typedef struct tagCOPYDATASTRUCT { ULONG_PTR dwData; DWORD cbData; PVOID lpData; } COPYDATASTRUCT, *PCOPYDATASTRUCT; 参数dwData 为自定义数据，按照自己习惯设置就好，不影响对象的传输； 参数cbData 表示传递数据的大小（以字节为单位 参数PVOID 表示传递的数据，是一个void*类型...

Windows.h 库函数的学习

By UINT Msg, WPARAM wParam, LPARAM lParam
| CSDN
句柄： 参考链接 1、FindWindow函数 该函数可以通过窗口类名或者窗口标题名来查找特定窗口句柄，返回值是窗口的句柄。 HWND FindWindowW( [in, optional] LPCWSTR lpClassName, [in, optional] LPCWSTR lpWindowName ); 微软windows.h API文档 这里可以用SPY++抓类名/窗口标题。 ​ ​ ​ ​ 抓目标窗口，这里就复制标题来抓句柄。 2、SendMessage函数 这个函数的功能是向句柄对应窗口发送指令 SendMessage function (winuser.h) - Win32 apps | Microsoft Docs LRESULT SendMessage( [in] HWND hWnd, [in] UINT Msg, [in] WPARAM wParam, [in] LPARAM lParam ); UNI 例子1- WM_CLOSE 代码 //摧毁窗口测试 void testHWND() { HWND window; //定义一个窗口句柄变量，用来储存窗口句柄...
