【逆向工具】使用x64dbg+spy去除WinRAR5.40(64位)广告弹框
|
1 学习目标
WinRAR5.40(64位)的弹框广告去除，由于我的系统为x64版本，所以安装了WinRAR(x64)版本。 OD无法调试64位的程序，可以让我熟悉x64dbg进行调试的界面。 其次是这玩意儿真是太蛋疼了，无休止弹广告。
1)偷梁换柱 修改汇编函数段首为返回值(本次逆向破解采用的方法) 2)NOP掉整个函数内容 3 涉及知识x64dbg工具快捷键与OD无异 F9：运行 bp CreateWindowExW：在x64dbg底部输入这行命令，对使用CreateWindowExW函数的位置断点。 CreateWindowExW：该函数创建一个层叠式窗口、弹出式窗口或子窗口。 参数： HWND CreateWindowEx( DWORD DdwExStyle, //窗口的扩展风格 LPCTSTR lpClassName, //指向注册类名的指针 LPCTSTR lpWindowName, //指向窗口名称的指针 DWORD dwStyle, //窗口风格 int x, //窗口的水平位置 int y, //窗口的垂直位置 int nWidth, //窗口的宽度 int nHeight, //窗口的高度 HWND hWndParent, //父窗口的句柄 HMENU hMenu, //菜单的句柄或是子窗口的标识符 HINSTANCE hInstance, //应用程序实例的句柄 LPVOID lpParam //指向窗口的创建数据 ); 4 实现流程【软件名称】：WinRar 【软件版本】：5.4 【外壳保护】：无 【操作系统】：Windows 10 既然是弹出窗口，首先要知道弹窗窗口的窗口类名，我使用的是VS2015里自带的工具Spy++ x64。
通过上诉步骤得到WinRAR的类名为RarReminder后，使用x64dbg工具载入WinRAR.exe。在命令的地方使用断点命令【bp CreateWindowExW】，在CreateWindowEx函数断下断点。F9运行到各个断点时观察广告窗口弹出的状态变化。
F9运行到出现RarReminder字样的地方，x64dbg这款工具还具备查看断点触发的次数的功能，通过【断点】选项卡看到断点共触发了30次才到这里。
在堆栈窗口在call指令的地方按回车键返回到用户层函数。
