Figuring out the Email-Worm Win32.Zafi.b

This is another just I just saw on the web and wanted to talk about what this little Worm does and what it’s known Aliases:

Email-Worm.Win32.Zafi.b (Kaspersky Lab) is also known as: I-Worm.Zafi.b (Kaspersky Lab), W32/Zafi.b@MM (McAfee), W32.Erkez.B@mm (Symantec), Win32.Hazafi.30720 (Doctor Web), W32/Zafi-B (Sophos), Win32/Zafi.B@mm (RAV), PE_ZAFI.B (Trend Micro), Worm/Zafi.B (H+BEDV), W32/Zafi.B@mm (FRISK), Win32:Zafi-B (ALWIL), I-Worm/Zafi.B (Grisoft), Win32.Zafi.B@mm (SOFTWIN), Worm.Zafi.B (ClamAV), W32/Zafi.B.worm (Panda), Win32/Zafi.B (Eset)

[ad#ad2-left]This worm spreads via the Internet as an attachment to infected messages, and also via local and file-sharing networks.
It is written in Assembler, and packed using FSG. It is 12800 bytes in packed form, and 33292 in unpacked form.

This Worm seems to be running through email and file sharing sites, One thing it tries to do is stop the process and deletes:
fvprotect.exe
winlogon.exe
jammer2nd.exe
services.exe

It attempts to detect antivirus program files on the computer and overwrite them with a copy of itself.

[ad#ad2-right]It also attempts to conduct DoS attacks on the following sites:

www.2f.hu
www.parlament.hu
www.virusbuster.hu
www.virushirado.hu

This seems to be a very big virus and can be removed with the use of Kapersky Virus removal tool for free for this type of virus. In order to prevent this virus in the future the user has to remember about not getting opening unknown documents or emails and not running any unkown program from an unknown file sharing.   Also remember you need to have an anti-virus  and also a firewall to protect yourself in the future.

Inside understanding of win32.netsky.q

Netsky.Q is a worm that spreads through e-mail. It is distributed as a 28,008 byte Win32 executable, compressed with PEtite, which drops a 23,040 byte DLL file. It also distributes itself inside ZIP archives.

I saw this on on the net and through we should talk about and let people know how you could get that the worm off your computer. It seems to be a self-replicating worm, it will continue to send out fake messages to people with the subject lines Like:
[ad#ad2-left]

  • Delivery Error
  • Delivery Failure
  • Delivery
  • Mail Delivery failure
  • Mail Delivery System
  • Mail System
  • Delivery
  • Delivered Message
  • Error
  • Status
  • Failure
  • Failed
  • Unknown Exception
  • Delivery Failed
  • Deliver Mail
  • Server Error
  • Delivery Bot

And with each message there is the reciepts email address at the end.  This worm seems to be spreading like wildfire today.   It is because people have not install

Microsoft Security Bulletin (MS01-020)

[ad#ad2-right]Now how do you get rid of it.  It seems that most of Anti-Virus software would get it done.  All you would need to do is scan for this virus with the latest updated virus databases and will go away.   According E-Trust Anti-Virus they say they can remove it.   This is a really old virus, according to my sources this was first seen in 2004.   In order to prevent this in the future I’d suggest installing a free anti-virus and using it.    This is one smart little worm according to CA IT.

If you have quite a few Desktops in your Office and want to update all of them to the newest patch all in one swoop, I’d suggest downloading Clone of Autopatcher and making an ISO image so you can go around to each computer and install the patches quickly and easily.  Prevent yourself from getting that virus and some others in the future.   This is a friendly tip for all those hard working IT workers.

Fix Shutdown Problems in Vista!

[ad]
In the Patch Tuesday update, Microsoft quietly released the patch to fix Windows Vista machine shut problems. This patch should of came sooner.

KB957388

Update for Windows Server 2008 and Windows Vista

Install this update to resolve a set of known application compatibility issues with Windows Server 2008. After you install this item, you may have to restart your computer.

This was not a critical update and it seems to resolve so many issues with compatibility.  One thing it seemed to fix on my system has been the shutdown time.  It is now quite fast, it would normally take me 2 to 3 mins to shutdown, now it does it in less than a Minute.   So if you’ve not installed this update please install it soon.   I would like to know if people are seeing the same thing I am.   I’ve found a great resource on fixing it if you are still having problem, it talks about how to check your system performance. Although this is been doing it lately with these programs not loaded or even running, they still seem to cause problems so now I get the feeling it has to do with legacy programs.  This should fix most of the problem with older programs.

Rumor is that Itunes will Remove DRM!

[ad#ad2-right]A report from last week brought to AppleInsider‘s attention by French technology site ElectronLibre asserts that it’s now “clear” Apple will spark new interest in its music store by removing DRM from tracks published by Sony, Universal and Warner on December 9th.

[Via Apple Insider]

Although, this is somewhat unlikely I’ve got my own theories on this.  You see If Apple did this tomorrow that would be a BIG deal, due to the fact that Microsoft will be releasing there patches on the same day.  I find it would be a momentous occasion.

[ad#ad2-left]I can only guess why and the guess is just a guess.  If Itune’s did remove there DRM the same time as Microsoft Patch Tuesday, I’d have to guess they will co-inside because of the difficulty of using the DRM, Digital Rights Management, on other products.  For example, Windows Media Player .  If Apple decided to approach Microsoft and come up with a way to make sure all DRM is stripped this would be the ideal situation.   Although this is highly unlikely, I’d have to think Apple wouldn’t wait till tomorrow to strip the DRM.  They know Microsoft schedule.  We will have to find out in the coming days.

Upcoming Patch Tuesday

[ad#ad2-right]I wanted to get prepared for the updates for this Tuesday and I thought I’d go through them and list what Microsoft said about each.   These are what’s been said on Technet and I am sure there will be more.   Each one of these don’t look to serious but I will post Tuesday if there is anything I’ve missed on this post.   As you might know this is not set in stone but just the direction of Microsoft for this Months Release.
