最新Winrar 32位中国代理版爆破笔记

winrar中国代理版本每次运行都会弹出广告窗口，并且主窗口标题栏会有许可到期时间的提醒，爆破的目的是去掉这两项。

该方法非常理想，所以借鉴了一下，适合我这种菜菜来练习动手能力。

使用OD加载winrar，如图：

按F9键运行winrar软件，直到弹出主窗口和广告窗口时，按F12键暂停程序，此时点击OD上方的“K”按键或者点击"ALT+K"来查看程序调用的堆栈，查看一下窗口弹出前的函数调用情况，得到如下图所示：

这一步需要注意的是需要看到广告窗口正常弹出，没有其他提示再暂停程序然后查看堆栈，例如在调试时遇到的如下图：

下图只在我们正常看到广告页时才会到这一步。

右击最后一条调用如图所示，选择“显示调用”命令。

得到如下图的调用位置：

直接在该位置点击回车键或者F7步进调试，我们会得到下面的汇编代码段，这段内容包含我们想破解的两处，即去广告和去标题的许可过期提示，看代码注释就可以判断了。

其中在“DestroyWindow”这一处(这里有两处，分别代表关闭主窗口和广告窗口，不知道是哪个的话我们可以下断点测试一下)，应该是关闭窗口的操作，那么广告窗口应该就在它的上方，向上找相关调用，下断点调试肯定找到调用广告窗口的地方，判断出00AE1AB9位置的call WinRAR.00AA53A0这个函数调用，在这个位置向上找关键跳转，看看能否跳过这个函数调用，也可以直接nop掉该处的调用，找到00AE1AAE位置的跳转操作je short WinRAR.00AE1AB5，将其改为jmp 0x00AE1AF7直接跳过DestroyWindow函数，

另一处的修改我选择用Binary Ninja这款反编译工具来完成，因为这款软件的流程图排版比较合理容易分析，并且占用系统资源比较小，其右键"patch"功能在修改汇编代码方面相对比较优秀。

使用Binary Ninja加载winrar主程序后，按“G”键输入我们需要查找的地址，与OD的偏移地址不同，我们需要自己对应一下，00AE1520对应的是004E1520，直接查找该位置如图所示：

在上述代码中我们关注到有一处调用系统API函数IsWindowVisible(设置可见属性)的地方，即位置00AE1A4C处，这处如果调用起来的话就会使得标题栏对应的许可信息隐藏，那么我们在Binary Ninja中查找位置004E1A4C，得到如下图所示：

点选该位置所在的流程块的第一行即“push edi {var_18_13}”处，在左下角的“Cross References”窗口中可以看到两个地址跳转到它，分析之后我们判断可以将最早跳转的地址0x4e189a的汇编代码修改为“jmp 0x4e1a33”（在该位置右击-->"patch"-->"Edit Current Line",如图所示）

修改之后如下图：

完成这两步后保存好修改，然后我们运行一下winrar得到如图：这下可以软件可以安静的启动，没有广告弹窗和标题栏的许可过期提醒。

可是别高兴太早，我们将系统时间调至软件过期，重新启动winrar，还是会出现如下窗口，提示购买winrar许可。

重复运行、暂停、查看堆栈、查看调用、步进调试一系列操作我们会找到如下代码段，可以看到这段代码包含广告的链接地址http://ad.winrar.com.cn/show_2.html?L=7&bl=7&v=$Vpersonal&a=$A&src=pe001以及提醒许可过期需要重新购买的函数RarReminder。

完成修改后，点击鼠标右键，在弹出的菜单中依次选择“复制到可执行文件”-->“所有修改”-->“复制”。

然后在新窗口中右击选择“保存文件”即可保存修改。

整个世界彻底清净来，老衲要继续清修了^_^!!!!
