這只鴿子提示：中招后，貼日志求助的日子即將結(jié)束！做好系統(tǒng)基礎(chǔ)安全防護(hù)是每個用戶的當(dāng)務(wù)之急。“基礎(chǔ)安全防護(hù)”絕不僅僅是打幾個補丁的問題。熟悉一兩個性能好的安全軟件的使用也是必要的。否則，中招后，你自己就著急吧！

這只鴿子的要害是c:\windows\winlogon.dll。如果想辦法禁止這個dll加載運行，鴿子的文件全部可見圖1

這只鴿子的要害是這個c:\windows\winlogon.dll。
如果用SSM禁止c:\windows\winlogon.dll加載運行，則這只鴿子的文件全部可見。
這是Movgear.exe中捆綁的一只灰鴿子（Movgear.exe樣本來自安全12公里）。winlogon.exe的MD5值為：2de9f62c2b405e16cb66773747cf0f2d。

一、自Movgear.exe中提取winlogon.exe并將其植入系統(tǒng)后，autoruns、HijackThis、SREng日志中均無任何異常發(fā)現(xiàn)。
winlogon.exe釋放的文件有：
1、c:\windows\winlogon.exe
2、c:\windows\winlogon.dll
3、c:\windows\winlogonKey.dll
這兩個dll插入IE瀏覽器進(jìn)程。
即使不打開IE瀏覽器，IceSword的進(jìn)程列表中依然可見iexplore.exe。
c:\windows\winlogonKey.dll動態(tài)跟蹤所有應(yīng)用程序進(jìn)程（一旦開啟，立即插入。）
注意：即使顯示隱藏文件，用WINDOWS的資源管理器也看不到灰鴿子釋放的這三個文件。用IceSword才能看到。
二、注冊表改動包括：
1、在HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
添加：winlogon.exe（指向c:\windows\winlogon.exe）
2、在HKEY_USERS\.DEFAULT\Software\Microsoft\Internet Explorer\Extensions\CmdMapping
添加：
"{92780B25-18CC-41C8-B9BE-3C9C571A8263}"=dword:00002002
"{DEDEB80D-FA35-45d9-9460-4983E5A8AFE6}"=dword:00002002
"{FB5F1910-F110-11d2-BB9E-00C04F795683}"=dword:00002001
3、在HKEY_USERS\.DEFAULT\Software\Microsoft\Internet Connection Wizard
添加："Completed"=hex:01,00,00,00
4、在HKEY_USERS\.DEFAULT\Software\Microsoft\Internet Explorer\Toolbar\WebBrowser
添加：
"ITBarLayout"=hex:11,00,00,00,5c,00,00,00,00,00,00,00,34,00,00,00,1f,00,00,00,56,\

添加："Settings"=hex:0c,00,02,00,0a,01,ef,75,60,00,00,00
6、在HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Ext\Stats\

三、進(jìn)行上述觀察后，重啟系統(tǒng)。
重啟后，卡巴斯基報警（我的卡巴斯基為啟動加載）：發(fā)現(xiàn)灰鴿子。但卡巴斯基僅僅將c:\windows\winlogon.dll刪除；c:\windows\winlogon.exe和c:\windows\winlogonKey.dll卡巴斯基并不報毒。汗??！卡巴斯基越來越不爭氣了另外發(fā)現(xiàn)其winlogonKey.log文件。文件內(nèi)容為：

#?>.?:4?74;
四、查殺流程：
1、打開注冊表編輯器，展開HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
刪除灰鴿子的服務(wù)項：winlogon.exe
2、重啟系統(tǒng)。用IceSword找到并刪除鴿子釋放的那三個文件。
4、清理注冊表（刪除鴿子添加的注冊表項）。
