Dear Sir or Madam,
A new computer worm is attacking the computers around the world, the
serious problem is the most of the anti viruses cannot detect & clean
it... also the removal tool was not available on the Internet... other
serious problem presents when some of current anti viruses detect this
virus as other kind of virus (Worm 32 family) ... and usually these
antivirus delete the whole infected file (exe & autorun.inf ... ext)...
This virus infects computer, for instance by:
- Infecting the local hard disk drivers & executable applications
- Carrying himself on a removable medium such as a floppy disk, CD, or
USB drive.
- Sending himself over a local network or the Internet. This virus can
spread to other computers by infecting files on a network file system
or a file system that is accessed by another computer.
- Adding keys into Windows registry
This virus is mixture between worms, virus and maybe Trojan he is a
self-replicating computer program, attaches itself to existing
programs in the infected PC (modify files on a targeted computer). It
confused with computer worms. He can spread itself to other computers
without needing to be transferred as part of a host. And usually this
mixture of a computer worm and virus may be a Trojan horse too...
This virus blurring the line between viruses and worms (maybe Trojan
too) actually it is self-replicating Malware.
Description:
Nobody sure yet about the name of this new virus... Saturday, November
03, 2007 I submitted the virus exe file to "Virustotal" (Virustotal is
a service that analyzes suspicious files and facilitates the quick
detection of viruses, worms, Trojans, and all kinds of Malware
detected by antivirus engines) and I got these results:
Antivirus Result
AVG Worm/Generic.DKD
BitDefender Win32.Worm.P2P.VBT
CAT-QuickHeal Worm.AutoRun.tk
F-Secure Virus.Win32.AutoRun.tk
Ikarus Win32.Worm.P2P.VBT
Kaspersky Virus.Win32.AutoRun.tk
Panda Suspicious file
Sophos W32/Dawin-A
VBA32 Virus.Win32.AutoRun.tk
The manger antivirus engines give different name for this virus
(Malware) I think that means two things:
1- There is no specific name of this virus
2- Each antivirus engine handles this virus in a different way. And
does not detect the latest version of him (detects him as other kind
of virus - Worm 32 family)
Technical Details:
When executed, the virus drops file / component (a copy of itself)
"KB915865.exe" in all physical drives. That includes too all removable
drives, such as flash disks. It creates the folder "\MSOCache
\90000804-6000-11D3-8CFE-0150048383C9\" in drives it affects, and
drops a copy of itself as "KB915865.exe" This folder is set to Hidden
and System.
\MSOCache\90000804-6000-11D3-8CFE-0150048383C9\KB915865.exe
Also it drops an AUTORUN.INF file to automatically execute dropped
copies when the drives are accessed. The said file contains the
following strings:
[AutoRun]
open=.\MSOCache\90000804-6000-11D3-8CFE-0150048383C9\KB915865.exe .
shellexecute=.\MSOCache
\90000804-6000-11D3-8CFE-0150048383C9\KB915865.exe .
shell\Open\command=.\MSOCache
\90000804-6000-11D3-8CFE-0150048383C9\KB915865.exe .
shell=Open
open=.
This virus creates registry entries to enable its automatic execution
at every system startup.
Platform:
This worm affects systems running on Windows 98, ME, NT, 2000, XP, and
Server 2003.
Solution:
I wrote a specific removal tool for this virus (e-nil! Virus Cleaner),
it is free and available on my blog:
