病毒癥狀
該樣本是使用 "VC” 編寫的木馬程序,由微點(diǎn)主動防御軟件自動捕獲,采用 "UPack” 加殼方式試圖躲避特征碼掃描,加殼后長度為 "15,045” 字節(jié),
圖標(biāo)為"" , 使用 "exe " 擴(kuò)展名,通過文件捆綁、網(wǎng)頁掛馬、下載器下載等方式進(jìn)行傳播。病毒主要目的是盜取網(wǎng)游帳號和密碼。
用戶中毒后會出現(xiàn)系統(tǒng)運(yùn)行緩慢、出現(xiàn)不明服務(wù)項、殺毒軟件失效、重要信息丟失等現(xiàn)象。
感染對象
Windows 2000/Windows XP/Windows 2003/Windows Vista/ Windows 7
傳播途徑
文件捆綁、網(wǎng)頁掛馬、下載器下載
防范措施
已安裝使用微點(diǎn)主動防御軟件的用戶,無須任何設(shè)置,微點(diǎn)主動防御將自動保護(hù)您的系統(tǒng)免受該病毒的入侵和破壞。無論您是否已經(jīng)升級到最新版本,微點(diǎn)主動防御都能夠有效清除該病毒。如果您沒有將微點(diǎn)主動防御軟件升級到最新版,微點(diǎn)主動防御軟件在發(fā)現(xiàn)該病毒后將報警提示您發(fā)現(xiàn)“未知木馬”,請直接選擇刪除處理(如圖1)
圖1 微點(diǎn)主動防御軟件自動捕獲未知病毒(未升級)
如果您已經(jīng)將微點(diǎn)主動防御軟件升級到最新版本,微點(diǎn)將報警提示您發(fā)現(xiàn)木馬 "Trojan-PSW.Win32.OnlineGames.fraf”,請直接選擇刪除(如圖2)。
圖2 微點(diǎn)主動防御軟件升級后截獲已知病毒
未安裝微點(diǎn)主動防御軟件的手動解決辦法:
(1)手動刪除以下注冊表項:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
名稱:HBService32
數(shù)據(jù):System.exe
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\

HKLM\SYSTEM\CurrentControlSet\Services\HBKernel32\
(2)刪除以下文件
%SystemRoot%\system32\HB1000Y.dll
%Temp%\HBSelfDel.dll
%SystemRoot%\system32\drivers\HBKernel32.sys
%SystemRoot%\system32\System.exe
變量聲明:
%SystemDriver% 系統(tǒng)所在分區(qū),通常為“C:\”
%SystemRoot% WINDODWS所在目錄,通常為“C:\Windows”
%Documents and Settings% 用戶文檔目錄,通常為“C:\Documents and Settings”
%Temp% 臨時文件夾,通常為“C:\Documents and Settings\當(dāng)前用戶名稱\Local Settings\Temp”
%ProgramFiles% 系統(tǒng)程序默認(rèn)安裝目錄,通常為:“C:\ProgramFiles”
病毒分析:
(1)在%SystemRoot%\system32目錄下釋放動態(tài)鏈接庫HB1000Y.dll和可執(zhí)行文件System.exe,在%SystemRoot%\system32\drivers目錄下釋放HBKernel32.sys文件,釋放動態(tài)鏈接庫HBSelfDel.dll到%Temp%目錄下
(2)注冊成名為HBKernel32的服務(wù)并啟動此服務(wù)以加載驅(qū)動HBKernel32.sys,用于恢復(fù)系統(tǒng)服務(wù)表一些表項,使殺軟主動防御無效或躲避殺軟查殺
(3)添加以下注冊表項實現(xiàn)System.exe的開機(jī)啟動:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
名稱:HBService32
數(shù)據(jù):System.exe
(3)木馬程序運(yùn)行System.exe之后,利用HBSelfDel.dll以命令行方式刪除自己。System.exe病毒程序則修改以下注冊表實現(xiàn)動態(tài)鏈接庫的重啟加載:
