簡介
病毒別名:W32.Erkez.B@mm[NAV], I-Worm.Zafi.b[AVP], PE_ZAFI.B[Trend], W32/Zafi.b@MM[McAfee], Zafi.B[CA], W32/Zafi-B[Sophos]
處理時間:2004-06-10
中文名稱:災飛
病毒類型:蠕蟲病毒
影響系統:Win9x/WinMe/WinNT/Win2000/WinXP/Win2003
病毒行為
1.病毒創建互斥體“_Hazafibb”,避免自身多次運行。
2.拷貝自身到%System%目錄,檔案名稱由八個隨機字母組成,擴展名為.exe或.dll。
3.創建註冊表鍵值:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\_Hazafibb
同時在註冊表主鍵:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
中添加鍵值:
"_Hazafibb"="%system%\<隨機字元>.exe"
以便該病毒在每次重啟 Windows 時運行。
winamp 7.0 full_install.exe 或者 Total Commander 7.0 full_install.exe
5.隨機打開一個web頁面,地址從註冊表以下主鍵中選取:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\TypedURLs
6.病毒會通過連線下面兩個網址之一來確定用戶是否聯網
7.病毒會向下列網站傳送大量HTTP Get請求,進行拒絕服務(DoS)攻擊
8.病毒阻止用戶運行含有下面字元串的程式:
regedit
msconfig
task
這將直接造成中毒計算機的註冊表管理器,系統配置實用程式,任務管理器等不能使用。
9.病毒搜尋一些知名反病毒產品所在的目錄,然後用自身覆蓋其中的.exe檔案。
10.病毒在擴展名為以下的檔案中搜尋Email地址,存儲到%system%\<8位隨機字元>.dll中:
.htm,.wab,.txt,.dbx,.tbb,.asp,.php,.sht,.adb,.mbx,.eml,.pmr,
不過,搜尋中會跳過包含了以下字元串的Email地址,避免向管理員,大網站和反病毒公司髮帶毒郵件,隱蔽自己:
admi,cafee,google,help,hotm,info,kasper,micro,msn,panda,sopho,suppor,syma,trend,
use,vir,webm,win,yaho
11.然後病毒使用自帶的SMTP引擎向搜尋到的Email地址傳送郵件。郵件內容為英文,不過當Email的主機為以下時,信的內容使用當地語言:
.hu,.sp,.ru,.dk,.ro,.se,.no,.fi,.lt,.pl,.pt,.de,.nl,.cz,.fr,.it,.mx,.at
帶毒郵件特徵
發件人:偽裝成帶有欺騙性得發件人
主題:空
附屬檔案:檔案名稱由隨機字元構成,後綴名為:.com, .exe,或者.pif。
正文:根據郵件地址的域名變化。
也就是說,郵件內容根據上面一點中所提到得域名不同而不同,如下之一:
