查看壳：
一、寻找OEP
1、一步直达法
（1）载入程序：
（2）不要运行，往下翻页，直到看到如下图的无效代码，有一个 JMP 跳转指令，对它下F2断点
（3）重新载入OD，F9运行，如图：
（4）成功到达OEP
2、堆栈平衡（ESP定律）
（1）载入OD：
（2）F8 运行，寻找第一次ESP寄存器改变的值为：0018FF6C ， 右键“数据窗口中跟随”
（3）给 0018FF6C 数据下硬件断点【PS：在调(Debug)中可找到 硬件断点查看硬件断点】
（4）和上述过程一样
3、利用应用程序调用的第一个API函数来定位OEP
（1）载入OD，和上述方法一样，不在赘述
（2）Ctrl + G 输入“GetVersion”，对它F2下断
（3）重新载入OD，F9执行，然后F8 执行到返回
（4）返回后，可以看到如下图所示，然后网上翻阅就可以看到OEP
二、IAT重建
使用的工具有 LoadPE 和 ImportREC
（1）OD中定位到 OEP 处，使用LoadPE工具dump为文件dumped[此时不可执行]，之后可以关闭LoadPE
（2）下面来 定位IAT的 起始位置 和 结束位置
由于很明显的找到了GetVersion 这个由系统动态链接库调用的函数，可以作为切入点
咦，看到了好多地址唉，可以点击"M"窗口看到他们是那个模块的动态链接库对吧
（PS：往往我们看这个可读性低，可以直接转换成 地址形式 查看）
转换成 如下：

00464698 00000000
可以看出来：IAT 起始位置是 00464000 结束位置是 00464698
计算的SIZE = 00464698 - 00464000 = 698（十六进制）
综上所述：RVA ：464000 - 400000(映像基址) = 64000
SIZE = 00464698 - 00464000 = 698OEP
OEP = 00445151 - 400000(映像基址) = 45151
（3）下面来使用 ImportREC 修复 IAT
--------- 填充数据（上述计算的）
111. 选中123.exe程序
222. 填充数据
333. 按下“Get Imports”
444. 出现一个无效的提示：
555. 点击"Show Invalid",然后做如下操作
666. 之后就没有了 无效的 提示了
777. 之后 "Fix Dump"，选中已经 Dump的文件，然后就可以修正文件了，之后会提示 sucessfully
888. 现在你可以执行修正后的文件 Dumped_.exe
现在查看一下，可以看到增加了一个区段：.mackt ,这就是刚才成功添加的区段
PS：这是对自己学习的总结，大神不要吐槽
， 如果能帮到 刚学习壳的朋友也很高兴
此文件 杀软会提示病毒软件：
123.zip
一、寻找OEP
1、一步直达法
（1）载入程序：
（2）不要运行，往下翻页，直到看到如下图的无效代码，有一个 JMP 跳转指令，对它下F2断点
（3）重新载入OD，F9运行，如图：
（4）成功到达OEP
2、堆栈平衡（ESP定律）
（1）载入OD：
（2）F8 运行，寻找第一次ESP寄存器改变的值为：0018FF6C ， 右键“数据窗口中跟随”
（3）给 0018FF6C 数据下硬件断点【PS：在调(Debug)中可找到 硬件断点查看硬件断点】
（4）和上述过程一样
3、利用应用程序调用的第一个API函数来定位OEP
（1）载入OD，和上述方法一样，不在赘述
（2）Ctrl + G 输入“GetVersion”，对它F2下断
（3）重新载入OD，F9执行，然后F8 执行到返回
（4）返回后，可以看到如下图所示，然后网上翻阅就可以看到OEP
二、IAT重建
使用的工具有 LoadPE 和 ImportREC
（1）OD中定位到 OEP 处，使用LoadPE工具dump为文件dumped[此时不可执行]，之后可以关闭LoadPE
（2）下面来 定位IAT的 起始位置 和 结束位置
由于很明显的找到了GetVersion 这个由系统动态链接库调用的函数，可以作为切入点
咦，看到了好多地址唉，可以点击"M"窗口看到他们是那个模块的动态链接库对吧
（PS：往往我们看这个可读性低，可以直接转换成 地址形式 查看）
转换成 如下：

00464698 00000000
可以看出来：IAT 起始位置是 00464000 结束位置是 00464698
计算的SIZE = 00464698 - 00464000 = 698（十六进制）
综上所述：RVA ：464000 - 400000(映像基址) = 64000
SIZE = 00464698 - 00464000 = 698OEP
OEP = 00445151 - 400000(映像基址) = 45151
（3）下面来使用 ImportREC 修复 IAT
--------- 填充数据（上述计算的）
111. 选中123.exe程序
222. 填充数据
333. 按下“Get Imports”
444. 出现一个无效的提示：
555. 点击"Show Invalid",然后做如下操作
666. 之后就没有了 无效的 提示了
777. 之后 "Fix Dump"，选中已经 Dump的文件，然后就可以修正文件了，之后会提示 sucessfully
888. 现在你可以执行修正后的文件 Dumped_.exe
现在查看一下，可以看到增加了一个区段：.mackt ,这就是刚才成功添加的区段
PS：这是对自己学习的总结，大神不要吐槽
， 如果能帮到 刚学习壳的朋友也很高兴此文件 杀软会提示病毒软件：
