Spybot - hpsebc08.exe and msdirectx.sys

I have come across a virus that Symantec could not detect (as of March 21, 2005). The symptoms are:

- cannot open Word or Excel
- machine hangs up
- Symantec crashes
- regedit and task manager closes immediately

By using the rename trick (copy regedit.exe and rename it to regedit.com), I was able to open the registry and check out what is in the Run key.

Under these two keys:

HKLM\SOFTWARE\Windows\Microsoft\CurrentVersion\Run
HKLM\SOFTWARE\Windows\Microsoft\CurrentVersion\RunOnce

Is the value IPOT USB Service DRV32 which runs the file hpsebc08.exe. The file is hidden and located under c:\Windows\System32. If you do a search for hpsebc08, you'll also find a Prefetch file (.pf).

Symantec does pick up another file that it drops, msdirectx.sys, which is detected as the generic "hacktool.rootkit". This virus attempts to connect to an outside server using IP address 140.123.176.237 with port 19899.

I submitted a virus sample to Symantec and they have provided a rapidrelease definition, so the next public update should be able to detect this spybot variant.

Thanks for the detailed writeup! I made a couple rules for VirusScan Enterprise to block creation &/or execution of files by those names.

We aplicated these task:

1. reboot and press F8 and select safe mode
2. login as administrator
3. edit Regedit and find all keys IPOT USB Service DRIVER and delete
3.a Always remember backup of you Regedit (the Murphys law)
4. save and close Regedit
5. find in the System root System32, "hpsebc087.exe" the virus hidden like a system file of the operating system and delete.
6. scanning manually wiht your antivirus.
7. execute Microsoft anti-spyware.
8. Windows Update.
9. finally you can call to the "FROGMENGROUP"

I had another variant of this virus. In my case the executable file was compaq.exe. All the other parameters were the same: the register keys, the msdirectx.sys, the .pf file and the file was in System32 directory.

I had to use the WinXP CD to enter with the recuperation console in order to can delete the compaq.exe file. When I made it the computer return to function like usual.

I hope this help people with the same virus as us. Bye.

Thanks for the write-up on this. I was able to use process explorer to suspend and kill the process. I couldn't delete the exe though, for some reason. Updating my symantec defs and rebooting allowed auto-protect to detect it on bootup. I had also killed the process and deleted all the reg keys that start it on boot. Not sure if this contributed to it's removal or not.

Also, when I tried to access c$ or use remote assistance on the infected computer, it denied access until the virus was removed, even though I have local admin rights on it. Also, it was blocking vpc32.exe from running as well. Not sure exactly all this thing is doing, but it seems to be an example of how bad viruses/spyware can get. I think it could get much worse than this.

It's been several days, but I have only been able to find one antivirus company that can give a description about this virus - even Symantec's web site turns up zero results.

Sophos - W32.SDBot.WH Description

There we go, it's called W32.SDBot.WH.

For those of you struggling with an infected computer, here is a cleaning routine you can put to use. Copy this text into a batch file (i.e. whcleaner.bat):

pskill.exe hpsebc08.exe

pause

reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /v "IPOT USB Service DRV32" /f
reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce /v "IPOT USB Service DRV32" /f
reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx /v "IPOT USB Service DRV32" /f
reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices /v "IPOT USB Service DRV32" /f

pause

del %SystemRoot%\System32\hpsebc08.exe

pause


Then download the pskill utility at SysInternals.com (and extract the exe from the zip file), and place it in the same directory as the batch script. Double-click the script, and kill the virus.

I didn't bother with trying to remove msdirectx.sys because antivirus/antispyware already detects it.

I have a msdirectx.sys but there is no hpsebc08.exe. The runonce does not have any funny programs.

I have created an empty msdirectx.sys so it can not load. Is my computer semisafe?

I did not like McAfee to much. Trend Micro found the virus
for me.In my case the program was called sdkcore.exe.

I searched the registry for both compaq.exe (found around 12 extra instances) and msdirectx.sys (found 4 extras) that were there as well as the runservices/run keys.

Its gone now though.

I was looking at Symantec's writeup on W32.Mytob.AD@mm and noticed they mentioned <b>directx.sys</b> as <a href="http://securityresponse.symantec.com/avcenter/venc/data/hacktool.rootkit.html">Hacktool.Rootkit</a>;.

<i>Hacktool.Rootkit is used to install backdoors on systems. They are made up of a variety of programs and scripts that break into systems and attempt to hide evidence of the intrusion. Attackers use these kits to gain Administrator or Superuser access on vulnerable systems.</i>

Big picture: so now a mass-mailing worm has been enhanced with a rootkit sidekick. There'll undoubtedly be more where that came from.

this virus pretty sux. my norton only pick up the msdirectx.sys but not the .exe file. Just delete all msdirect.sys files first, it doesnt affect the system. This virus crashes the norton altogether. in my case it is called systeminfos.exe . i suppose the name might be quite different in different computers. but it was named "compaq service driver : systeminfos.exe" in the same registry entry mentioned by others . Just search and delete all entries associated with the infected .exe file. Also delete if u find any in :
c:windows
c:windowssystem32
c:windowsprefetch
