手动删除文件
1. 删除 %SystemRoot%\system32\killdll.dll
2. 删除 %SystemRoot%\system32\updater.exe
3. 删除 %temp%\~Frm.exe
4. 删除 %temp%\_undelme.bat
5. 删除 %temp%\tmp.tmp
6. 用正常的asyncmac.sys,aec.sys,pcidump.sys替换被感染文件文件。
手动删除注册表
1、手动删除注册表项:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
名称:updater
数据:C:\WINDOWS\System32\updater.exe
2,手动删除注册表:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution
Options\
下属所有映像劫持
3,删除注册表:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AsyncMac
名称:ImagePath
数据:System32\DRIVERS\asyncmac.sys
4,删除注册表:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AsyncMac
名称:ImagePath
数据:System32\DRIVERS\aec.sys
5,删除注册表:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\pcidump
名称:ImagePath
数据:\??\C:\WINDOWS\System32\drivers\pcidump.sys
病毒分析:
1, 病毒建立进程快照,查找当前进程,并且获得系统目录 ,在该目录下建立文件
“C:\WINDOWS\system32\killdll.dll”,并以隐藏窗口的形式启动进程CmdLine =
“C:\WINDOWS\System32\rundll32.exe C:\WINDOWS\System32\killdll.dll killall”。
2,病毒文件获得临时文件路径%temp%,在该目录下释放文件%temp%\~Frm.exe,并以隐藏窗口的形式启动进
程执行之。
3,病毒文件删除文件“C:\WINDOWS\system32\killdll.dll”。
4,病毒获得系统目录路径,将病毒移动到系统目录下并重新命名为:“C:\WINDOWS\system32
\updater.exe”
5, 病毒创建驱动文件C:\WINDOWS\system32\drivers\pcidump.sys,创建服务项并修改修改注册表信息:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\pcidump
名称:ImagePath
数据:\??\C:\WINDOWS\System32\drivers\pcidump.sys
以服务的方式加载该驱动文件,并将建立驱动管道"\\.\pcidump",与驱动文件进行驱动通信,该驱动
的目的是进行通信修改“userinit.exe”文件,把临时文件“%temp%\~Frm.exe”注入到
C:\WINDOWS\System32\ userinit.exe,来实现开机启动,然后删除 pcidump.sys对应服务项。
6,病毒在临时文件路径下创建批处理文件%temp%\ _undelme.bat, 完成后运行该批处理文件,删除病毒
源程序和批处理自身。
7,“killdll.dll”获取自身权限信息并将自身权限提升为SeDebugPrivilege权限。建立进程快照,查找
进程名“CCenter.exe”是否存在, “CCenter.exe”瑞星杀毒软件的相关程序进程,如果存在,先将
C:\WINDOWS\system32\drivers\ asyncmac.sys文件删除之,并重新建立C:\WINDOWS\system32\drivers\
asyncmac.sys驱动文件,修改注册表,建立服务项。
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AsyncMac
名称:ImagePath
数据:System32\DRIVERS\asyncmac.sys
以服务的方式加载该驱动文件并将建立驱动管道"\\.\Killps_Drv",与驱动文件进行驱动通信。该驱动发
送控制码222004,结束相关的安全软件进程。完成后建立所有查找的安全软件的映像劫持。安全进程名称
为:"avp.exe"“safeboxTray.exe""360Safebox.exe"
"360tray.exe""antiarp.exe""ekrn.exe""RsAgent.exe""egui.exe""RavMon.exe""RavMonD.exe""RavTask
.exe""AAglvgp,gzg"
"RavStub.exe""RsTray.exe""ScanFrm.exe""Rav.exe""AgentSvr.exe""AAglvgp,gzg""QQDoctor.exe""McP
roxy.exe""McNASvc.exe"
"Mcshield.exe""rsnetsvr.exe""MpfSrv.exe""MPSVC.EXE""MPSVC3.EXE""IKQQta,gzg""IKQQta,gzg""kmai
lmon.exe""KavStart.exe"
"KPFW32.EXE""KVMonXP.KXP""KVSrvXP.exe"
"ccSetMgr.exe""ccEvtMgr.exe""defwatch.exe""rtvscan.exe""ccapp.exe"
"vptray.exe""mcupdmgr.exe""mcproxy.exe""mcshield.exe""MPFSrv.exe""mcsysmon.exe""mcmscsvc.exe
""mcnasvc.exe"
"mcagent.exe""mcshell.exe""mcinsupd.exe""bdagent.exe""livesrv.exe""vsserv.exe""xcommsvr.exe"
对应的映像劫持路径为:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image
File Execution Options\
然后删除驱动文件“C:\WINDOWS\system32\drivers\ asyncmac.sys”
8,调用命令行,禁用ESET NOD32的服务项,并结束相关进程:
"cmd /c sc config ekrn start= disabled"
"cmd /c taskkill /im ekrn.exe /f"
以及卡巴斯基的服务项,并结束之:
"cmd /c sc config avp start= disabled"
"cmd /c taskkill /im avp.exe /f"
以及McAfee的服务项,并取消该杀软的服务启动:
"cmd /c sc config McNASvc start= disabled"
"cmd /c sc config MpfService start= disabled"
"cmd /c sc config McProxy start= disabled"
"cmd /c sc config McShield start= disabled"
"cmd /c sc config mcmscsvc start= disabled"
"cmd /c sc config Mcshield start= disabled"
以及BitDefenderProfessional的服务项并取消该杀软的服务启动:
"cmd /c sc config XCOMM start= disabled"
"cmd /c sc config LIVESRV start= disabled"
"cmd /c sc config scan start= disabled"
"cmd /c sc config VSSERV start= disabled
9.C:\WINDOWS\System32\killdll.dll先将"C:\WINDOWS\System32\drivers\aec.SYS"文件删除之,并重新
建立C:\WINDOWS\System32\drivers\aec.SYS
修改注册表,建立服务项。
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AsyncMac
名称:ImagePath
数据:System32\DRIVERS\aec.sys
以服务的方式加载该驱动文件, “aec.sys”驱动文件恢复SSDT来解除安全软件建立的系统钩子, 然后删
除驱动文件“C:\WINDOWS\system32\drivers\aec.sys”
以隐藏方式取消瑞星安全软件进程和服务项的启动,内容为:
"cmd /c sc config RavTask start= disabled"
"cmd /c sc config RsScanSrv start= disabled"
"cmd /c sc config RavTray start= disabled"
"cmd /c sc config RsRavMon start= disabled"
"cmd /c sc config RavCCenter start= disabled"
删除注册表项:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run,使所有的应用
程序启动项无法启动,然后重新建立注册表启动项。
10. %temp%\~Frm.exe 文件建立注册表启动项,
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
名称:updater
数据:C:\WINDOWS\System32\updater.exe
以便到底自启动的目的,~Frm.exe获得临时文件路径,在该目录下释放文件%temp%\tmp.tmp,然后建
立"C:\WINDOWS\System32\svchost.exe"进程,对该进程进行写内存操作,并建立远程线程注入,以及将
用户的网卡地址发送到黑客指定的网站。访问指定网址,下载大量病毒程序并运行。
病毒创建文件:
%SystemRoot%\system32\killdll.dll
%SystemRoot%\system32\updater.exe
%SystemRoot%\system32\drivers\asyncmac.sys
%SystemRoot%\System32\drivers\aec.sys
%SystemRoot%\system32\drivers\pcidump.sys
%temp%\~Frm.exe
%temp%\tmp.tmp
%temp%\ _undelme.bat
病毒删除文件:
%SystemRoot%\system32\drivers\aec.sys
%SystemRoot%\system32\drivers\AsyncMac.sys
%SystemRoot%\system32\drivers\pcidump.sys
%temp%\ _undelme.bat
