04 复制删除行为IDA反汇编
（很久以前的学习记录，放到博客上来）
(IDA5.0版的不知道为何反汇编进去每一行被截断的景象，惨不忍睹......明明是个正版的。只好回来用拷过来的破解版，依然有一些叽里呱啦的问题，懒得管了，勉强能用。)
之前的一个拷贝自身到C盘下，并删除自身的exe文件（Reverse 01 中的），拖到IDA里反汇编：

.text:004012F2 retn
GetModuleFileNameA， GetShortPathNameA之类的函数不是重点，唯一值得推测的是004012D5 call ds:ShellExecuteA
百度查了一下exe文件删除自身的方法，CSDN上确实有谈论过，也有人指出用ShellExecute可以实现（这点更加让我觉得ShellExecuteA很有可能是删除文件本身的关键所在），用了其上的代码，并没有实现删除exe本身，只是闪现了黑窗口（打开后关闭了黑窗口），可能这个类病毒实现删除自己实在复制过自己到C盘下后，由C盘下exe文件删除了自己？
附CSDN上的代码（并未实现删除exe本身） ：
#include <windows.h>
#include <fstream>
using namespace std;
int main()
{
ofstream file;
file.open("1.bat");
file<<"del 1.exe"<<endl;
file<<"del 1.bat"<<endl;
file.close();
ShellExecute(NULL,"open","1.bat","",NULL,SW_SHOWNORMAL);
}
告辞。
