這隻鴿子提示：中招後，貼日誌（zhì）求助的日子即將結束！做好係統（tǒng）基礎安（ān）全（quán）防（fáng）護是（shì）每個（gè）用（yòng）戶的當務之急（jí）。“基礎（chǔ）安全防（fáng）護”絕不（bú）僅僅是（shì）打幾個補丁的（de）問（wèn）題。熟悉一兩個性能（néng）好的安全軟件（jiàn）的使用也是必（bì）要的。否（fǒu）則，中招後（hòu），你（nǐ）自（zì）己（jǐ）就著急吧！

這隻（zhī）鴿子的（de）要害是（shì）c:\windows\winlogon.dll。如果（guǒ）想辦法禁止這個dll加載運行，鴿子的文（wén）件全部（bù）可見圖1

這隻鴿子（zǐ）的要害是這（zhè）個c:\windows\winlogon.dll。
如果用SSM禁止c:\windows\winlogon.dll加載運（yùn）行，則這隻（zhī）鴿子（zǐ）的文件全部（bù）可見。
這（zhè）是Movgear.exe中捆綁的一隻灰鴿子（Movgear.exe樣本（běn）來自安全12公裏）。winlogon.exe的MD5值為（wéi）：2de9f62c2b405e16cb66773747cf0f2d。

一、自Movgear.exe中提取winlogon.exe並將其植入係統後，autoruns、HijackThis、SREng日誌中均無任何異常發現。
winlogon.exe釋放（fàng）的文（wén）件有：
1、c:\windows\winlogon.exe
2、c:\windows\winlogon.dll
3、c:\windows\winlogonKey.dll
這（zhè）兩個dll插（chā）入IE瀏覽器進程。
即使不打開IE瀏覽器，IceSword的（de）進程列表中依（yī）然可見iexplore.exe。
c:\windows\winlogonKey.dll動態跟蹤（zōng）所有應（yīng）用程序進（jìn）程（一旦開啟，立（lì）即插入。）
注意：即（jí）使顯示隱藏文件，用WINDOWS的資源管理器（qì）也看不到灰鴿（gē）子釋放的這（zhè）三個文件。用IceSword才能（néng）看到。
二、注冊表改動包括（kuò）：
1、在（zài）HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
添加（jiā）：winlogon.exe（指向（xiàng）c:\windows\winlogon.exe）
2、在HKEY_USERS\.DEFAULT\Software\Microsoft\Internet Explorer\Extensions\CmdMapping
添加：
"{92780B25-18CC-41C8-B9BE-3C9C571A8263}"=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,\

5、在（zài）HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Explorer\CabinetState
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\
添加：

三（sān）、進行上述觀察後，重啟係（xì）統（tǒng）。
重啟後，卡巴斯基報警（我的卡（kǎ）巴斯基為啟動（dòng）加載）：發現灰鴿子。但卡（kǎ）巴斯（sī）基僅僅將c:\windows\winlogon.dll刪除（chú）；c:\windows\winlogon.exe和c:\windows\winlogonKey.dll卡巴斯基並不報毒（dú）。汗！！卡巴斯（sī）基越來越不爭氣（qì）了另外發現（xiàn）其（qí）winlogonKey.log文（wén）件。文件（jiàn）內（nèi）容為：

#?>.?:4?74;
四、查（chá）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（de）服務項（xiàng）：winlogon.exe
2、重啟係統。用IceSword找到並刪除鴿子釋放（fàng）的那三個（gè）文件。
4、清理（lǐ）注（zhù）冊表（刪除鴿子（zǐ）添加的（de）注冊（cè）表（biǎo）項）。

10月31日更新（xīn）
