[vc] dll永久注入exe文件

舒默哦

说明：
就是把dll文件拉伸贴在exe文件后面，先执行dll，然后跳回主程序入口继续执行。(其实，dll想什么时候执行就什么时候执行，具体看需求)



遇到的问题：
这儿修复IAT表，不能是静态修复，因为计算机每次重启，系统dll映射到exe程序所在的地址都会变，IAT表必须动态修复。
修复IAT表需要用到"LoadLibraryA"和GetProcAddress两个函数，这两个函数存在于KERNEL32这个DLL中，
可以通过FS寄存器找到进程环境块PEB，得到kernel32的地址，找到GetProcAddress函数所在地址，再通过GetProcAddress找到LoadLibraryA的地址。



具体步骤：
1、分别加载exe和dll到内存
2、给exe添加新节
3、处理dll（拉伸dll和以及修复重定位表)
4、申请新内存(大小=exe文件大小+新节大小)
5、获取dll的入口函数的指针
6、构造ShellCode
7、修改程序入口，跳到ShellCode地址处执行
8、保存文件



实验测试文件用到了LoadPE.exe和test_dll.dll，最后输出的文件是newfile.exe。

test_dll.dll

结语：
newfile.exe能够在win10上运行，不能在win7上跑(32位和64位都失败)。
有低版本的编译器的老铁可以试一下，在支持win7的编译器上编译，然后在win7上跑看能不能跑得动

奇安信要拦截这个dll

纯学习一下吧，包装exe，典型的shellcode模式啊

我只想到这种，还有其他方式吗？还有种方法是把dll分离出exe，放到一个临时文件加载后删掉，这样可以不用修复重定位和IAT表
