#1 机器狗、auto木马群、磁碟机大混血(AtiSrv.exe)
机器狗、auto木马群、磁碟机大混血AtiSrv.exe
本周一款融合机器狗、auto木马群、磁碟机特点的病毒大范围爆发。其主文件名为：AtiSrv.exe
该病毒会迫使杀毒软件失效，安全模式加载、下载大量盗号木马、劫持浏览器、写入rootkits驱动进行自保护....
该病毒简单特征分析：
释放自身到启动文件夹随机加载：
%ALLUSERSPROFILE%\「开始」菜单\程序\启动\AtiSrv.exe 如图所示：
写入执行挂钩：
HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\ShellExecuteHooks
ffHADHAD1042.dll
HKCR\CLSID\{1133c611-c3b1-4626-bd63-6605ea0d3486}
c:\windows\system32\ffhadhad1042.dll

winsys8v.sys
HKCR\CLSID\{6167F471-EF2B-41DD-A5E5-C26ACDB5C096}
c:\program files\internet explorer\plugins\winsys8v.sys（该文件会同时写入BHO加载）
写入Appinit_dlls由于写入过多dll信息导致sreng无法检测到该项目。数据如下：
bauhgnem.dll,eohsom.dll,fyom.dll,sauhad.dll,ijougiemnaw.dll,taijoad.dll,lnaixnauhqq.dll
idtj.dll,vhqq.dll,atgnehz.dll,rsqq.dll,tsqc.dll,vauyiqvlnaix.dll,wQ.dll,fmxh.dll,cty.dll,pahzij.dll

ijougiemnaw.dll,wtwx.dll,jghf.dll,msd.dll,asj.dll,her.dll,awf.dll,
目的是为了安全模式也能加载，导致用户修复安全模式无效。如图所示：
后台联网下载木马程序：
1=http://iii.xxxxx.com/wm/1.exe
2=http://iii.xxxxx.com/wm/2.exe
3=http://iii.xxxxx.com/wm/3.exe
4=http://iii.xxxxx.com/wm/4.exe
5=http://iii.xxxxx.com/wm/5.exe
6=http://iii.xxxxx.com/wm/6.exe
7=http://iii.xxxxx.com/wm/7.exe
8=http://iii.xxxxx.com/wm/8.exe
9=http://iii.xxxxx.com/wm/9.exe
10=http://iii.xxxxx.com/wm/10.exe
11=http://iii.xxxxx.com/wm/11.exe
12=http://iii.xxxxx.com/wm/12.exe
13=http://iii.xxxxx.com/wm/13.exe
14=http://iii.xxxxx.com/wm/14.exe
15=http://iii.xxxxx.com/wm/15.exe
16=http://iii.xxxxx.com/wm/16.exe
17=http://iii.xxxxx.com/wm/17.exe
18=http://iii.xxxxx.com/wm/18.exe
19=http://iii.xxxxx.com/wm/19.exe
20=http://iii.xxxxx.com/wm/20.exe
21=http://iii.xxxxx.com/wm/21.exe
22=http://iii.xxxxx.com/wm/22.exe
23=http://iii.xxxxx.com/wm/23.exe
24=http://iii.xxxxx.com/wm/24.exe
25=http://iii.xxxxx.com/wm/25.exe
26=http://iii.xxxxx.com/wm/26.exe
27=http://iii.xxxxx.com/wm/27.exe
28=http://iii.xxxxx.com/wm/28.exe
与auto木马群勾结，写入盗号木马：
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run]
<mhuslmqi><C:\WINDOWS\hsmijpow.exe>
<AVPSrv><C:\WINDOWS\AVPSrv.exE>
<upxdnd><C:\WINDOWS\upxdnd.exe>
<Kvsc3><C:\WINDOWS\Kvsc3.exE>
<DbgHlp32><C:\WINDOWS\DbgHlp32.exe>
<SHAProc><C:\WINDOWS\SHAProc.exe>等
加载rootkits驱动进行自我保护：
[iCafe Manager / iCafe Manager][Stopped/Manual Start]
<\??\C:\DOCUME~1\papa\LOCALS~1\Temp\usbhcid.sys>
[Sc Manager / Sc Manager][Running/Manual Start]
<\??\C:\DOCUME~1\papa\LOCALS~1\Temp\usbcams3.sys>
[dohs / dohs][Stopped/Auto Start]
<\??\C:\DOCUME~1\papa\LOCALS~1\Temp\tmp3.tmp>
[fpids32 / fpids32][Running/Auto Start]
<\??\C:\WINDOWS\system32\drivers\msosfpids32.sys>
[msertk / msertk][Running/Auto Start]
<system32\drivers\msyecp.sys>
[msert / msert][Running/Auto Start]
<system32\drivers\mselk.sys>
写入ntsd劫持与破坏安全模式，导致杀软失效，如图所示：
详细劫持文件列表请见： 劫持文件列表.txt (1.83 KB)
该病毒的处理方法：
该病毒融合了目前多种流行病毒木马技术，破坏杀毒程序导致普通用户很难进行清理操作。建议用户对该病毒以注意日常防范为主，保持毒霸病毒库更新以及良好健康的上网习惯。
对于已经中此病毒的用户可以尝试在正常模式运行使用附件中的脚本Del_AtiSrv.bat后断电重启进入安全模式。
（注意：断电法有操作风险，请谨慎考虑是否采纳该方法。操作前务必备份重要资料以及文件。）
进入安全模式后运行附件中的Clean_IFEO.bat清除映像劫持，并运行金山清理专家清理恶意软件即可。如图所示：
