处理时间:2004-06-10

威胁级别:★★

中文名称:灾飞

病毒类型:蠕虫

影响系统:Win9x / WinNT

§ 病毒行为:

这是一个用FSG压缩,通过邮件传播的蠕虫病毒,同时该病毒还通过共享网络磁盘传播。病毒还会覆盖反病毒软件的可执行文件造成其不能使用。

1.病毒创建互斥体“_Hazafibb”,避免自身多次运行。

2.拷贝自身到%System%目录,文件名由八个随机字母组成,扩展名为.exe或.dll。

3.创建注册表键值:

HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\_Hazafibb

同时在注册表主键:

HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run

中添加键值:

"_Hazafibb"="%system%\\<随机字符>.exe"

以便该病毒在每次重启 Windows 时运行。

4.病毒搜索硬盘上共享的网络映射盘,拷贝自身到共享文件夹并命名为:

winamp 7.0 full_install.exe 或者 Total Commander 7.0 full_install.exe

5.随机打开一个web页面,地址从注册表以下主键中选取:

HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\TypedURLs

6.病毒会通过连接下面两个网址之一来确定用户是否联网:

www.google.com

www.microsoft.com

7.病毒会向下列网站发送大量HTTP Get请求,进行拒绝服务(DoS)攻击:

www.parlament.hu

www.virusbuster.hu

www.virushirado.hu

www.2f.hu

8.病毒阻止用户运行含有下面字符串的程序:

regedit

msconfig

task

这将直接造成中毒计算机的注册表管理器,系统配置实用程序,任务管理器等不能使用。

9.病毒搜索一些知名反病毒产品所在的目录,然后用自身覆盖其中的.exe文件。

10.病毒在扩展名为以下的文件中搜索Email地址,存储到%system%\\<8位随机字符>.dll中:

.htm,.wab,.txt,.dbx,.tbb,.asp,.php,.sht,.adb,.mbx,.eml,.pmr,

不过,搜索中会跳过包含了以下字符串的Email地址,避免向管理员,大网站和反病毒公司发带毒邮件,隐蔽自己:

admi,cafee,google,help,hotm,info,kasper,micro,msn,panda,sopho,suppor,syma,trend,

use,vir,webm,win,yaho

11.然后病毒使用自带的SMTP引擎向搜索到的Email地址发送邮件。邮件内容为英文,不过当Email的主机为以下时,信的内容使用当地语言:

.hu,.sp,.ru,.dk,.ro,.se,.no,.fi,.lt,.pl,.pt,.de,.nl,.cz,.fr,.it,.mx,.at

12.带毒邮件的特征为:

发件人:伪装成带有欺骗性得发件人

主题:空

附件:文件名由随机字符构成,后缀名为:.com, .exe,或者.pif。

正文:根据邮件地址的域名变化。

也就是说,邮件内容根据上面一点中所提到得域名不同而不同,如下之一:
