悠悠鸟影视论坛(uuniao)主站被挂网马中的木马分析

所属分类:lcx

这是一篇木马分析文章,这篇文章的内容紧接着:悠悠鸟影视论坛(uuniao)主站被黑,并被“黑客”植入网马挂马!


dd01.css 这个木马信息如下:

大小:24.5 KB (25,088 字节)

MD5:A43EAC1037D1EE14BD3F1FC632DF1EBC

加壳:UPX 0.89.6 - 1.02 / 1.05 - 1.22 -> Markus & Lazlo

直接脱壳:

File size       Ratio    Format   Name
--------------  -------  --------  --------
48640 

脱壳后:

大小:47.5 KB (48,640 字节)

MD5:BE8EA2ED75EB0E4914759CEA80524695

Unidentified Packer. *

木马运行后会首先检测主流杀毒软件,列表如下:

ASCII "avp.EXE"         //卡巴斯基杀毒软件
ASCII "egui.exe"        //Eset NOD32 Antivirus
ASCII "360rp.exe"       //360杀毒软件
ASCII "360sd.exe"       //360杀毒软件
ASCII "kavstart.EXE"    //金山毒霸杀毒软件
ASCII "RsTray.exe"      //瑞星卡卡上网安全助手
ASCII "RavMonD.exe"     //瑞星杀毒软件

并在临时文件目录创建六位随机数字名字的dll,在系统目录创建六位随机数字名字的exe。

并调用批处理进行自删除,具体的就不写了,在线程序行为分析结果见:

http://anubis.iseclab.org/?action=result&task_id=1dc9b871da00d8cf439efff55da61744d&format=html

上线地址:ad.ddnc.net:8832 --> 58.221.36.210 --> 江苏省南通市 电信

和之前的 huandan4.8866.org [58.221.36.212] 是同段服务器!

并且这个 IP 已经有很长时间挂马历史了,上了很多黑名单。

例如:http://www.kafan.cn/article-3462-1.html

挂马者有相当多免费域名,但端口无一例外都是:8832

挂马者至少拥有数台服务器,并且分工明确,一看就是专业挂马的,并且规模相当大。

这年头居然还专业挂马户,尼玛挂的还是国内的!不想活了!

那个谁有兴趣的话,去日了他服务器,把小马换成自己的,绝对超多肉鸡,黑吃黑不解释……

该木马检测主流杀毒软件的作用可以说一下吗

本站回复:

通过遍历进程判断杀毒软件,可以执行对应绕过方式,稍微高级一点的木马都有此功能。
