疾風病毒及其變種最新說明---使用不同的方法
疾風病毒及其變種最新說明---使用不同的方法
1. 疾風病毒至今有 Lovesan,Lovsan, Blaster,Msblast and Poza 的名字 各家AV命名不同
其他廠商對此病毒的不同稱呼如下：
DcomRPC.exploit,
W32.Blaster.Worm (Symantec) ,
W32/Blaster (CERT),
W32/Lovsan.worm (McAfee),
W32/Msblast.A (F-Secure) ,
Win32/Poza.Worm ,
WORM_MSBLAST.A (Trend)
2. 如何判斷已中疾風病毒
a. 在你電腦 X:\Windows\Systems32\的目錄下 有下列的檔案之一 Msblast.exe, Teekids.exe or Penis32.exe
b. 有重開機的訊息或畫面
c. 使用MS Word, Excel or Outlook. 有錯誤的訊息
d. svchost.exe 有錯誤的訊息
e. RPC Service Failure RPC錯誤的訊息
3. 疾風病毒攻擊的作業系統
Windows NT 4.0 Server
Windows NT 4.0 Terminal Server Edition
Windows 2000
Windows XP 32 bit Edition
Windows XP 64 bit Edition
Windows Server 2003 32 bit Edition
Windows Server 2003 64 bit Edition
4. 因為一直重開機 不能下載 Microsoft修正檔修正法
a. 移除網路線
b. 你需要一支 TFTP.EXE 的檔案 這檔案原始的在 \Windows\System32\dllcache 目錄中 將它 COPY至 \Windows\System32\的目錄中 (原TFTP.EXE已中毒了)
c. 接上網路線
d. 下載 Microsoft修正檔
確認「服務」裡面的「Cryptographic Services」有沒有啟動
沒有的話,啟動他....
f. 慣修正檔
Poza 開始掃瞄所有子網域，以尋找 TCP 135 埠為開啟狀態的電腦，接著隨機掃瞄幾個選擇的 B 級子網域 (255.255.0.0)。如果找到可開啟 TCP 135 埠的電腦，Poza 會利用之前提到的安全漏洞進行電腦，並在被感染的電腦上建立一個遠端控制的命令層。一旦成功入侵，Poza 會嚐試連結遠端電腦的 TCP 4444 埠。順利連結之後，Poza 會指示被感染電腦到遠端電腦下載透過 TFTP.EXE 執行 FTP 服務的 MSBLAST.EXE 檔案（檔案大小：6,176 bytes，採 UPX 自解壓縮方式封裝檔）。接著送出指令，執行被感染電腦中的 MSBLAST.EXE。
註：TFTP.EXE 是一項在 Windows 2000 之後版本的 Windows 作業系統中，預設安裝的一項工具軟體。此病毒蟲也會保持同時連結至其他 20 台被感染的電腦。
5. 如果你已經中疾風病毒
下載下列清除檔 清除後 再下載Microsoft修正檔 再慣修正檔

-------------------------------------
If program find next processes in memory:
Krn132.exe
WQK.exe
or any processes, infected by these viruses, it will try to
unhook virus hooks and patch needed processes to stop reinfection and then
stop them and delete/cure their files on hard drive and delete links to their
files from system registry and other startup places.
If program find that WQK.DLL library has been loaded by any processes
it will rename file of this library and will remove it after system reboot.

PC when program finish and start it the second time after reboot to clean your
system registry.
If program find any infected processes in memory it will start scan of
your hard drive (and all mapped network drives if you specify /netscan in
command line). It will check only infection by these viruses.
If you specify /s key in command line program will scan your hard drive
(and all mapped network drives if you specify /sn) in all cases.
If Win32.Elkern.c virus create memory mapping, program will disinfect
this memory area.
