直接给出分析的总结吧。程序只是为了刷访问量，没有什么后门，也就隐藏了URL，用XXXX代理了。
程序运行后，你的电脑会访问 http://www.xxxxxxxx.com/tc/MMResult.asp
看代码

把自身复制到c:/windows/，会生成批处删本地目录运行程序。
killme.bat
echo off
sleep 100
del rundll322.exe
del killme.bat
cls
exit
程序的运行方式是 写注册表
software\microsoft\windows\currentversion\run
键值rundll32.exe
程序写的不好，要插入进程，那效果会好点。只要把他程序的URL修改一下这个木马就可以自己使用了 上一页 [1] [2] |
