Parent class: VirWare
Viruses and worms are malicious programs that self-replicate on computers or via computer networks without the user being aware; each subsequent copy of such malicious programs is also able to self-replicate. Malicious programs which spread via networks or infect remote machines when commanded to do so by the “owner” (e.g. Backdoors) or programs that create multiple copies that are unable to self-replicate are not part of the Viruses and Worms subclass. The main characteristic used to determine whether or not a program is classified as a separate behaviour within the Viruses and Worms subclass is how the program propagates (i.e. how the malicious program spreads copies of itself via local or network resources.) Most known worms are spread as files sent as email attachments, via a link to a web or FTP resource, via a link sent in an ICQ or IRC message, via P2P file sharing networks etc. Some worms spread as network packets; these directly penetrate the computer memory, and the worm code is then activated. Worms use the following techniques to penetrate remote computers and launch copies of themselves: social engineering (for example, an email message suggesting the user opens an attached file), exploiting network configuration errors (such as copying to a fully accessible disk), and exploiting loopholes in operating system and application security. Viruses can be divided in accordance with the method used to infect a computer:- file viruses
- boot sector viruses
- macro viruses
- script viruses
Class: P2P-Worm
P2P Worms spread via peer-to-peer file sharing networks (such as Kazaa, Grokster, EDonkey, FastTrack, Gnutella, etc.). Most of these worms work in a relative simple way: in order to get onto a P2P network, all the worm has to do is copy itself to the file sharing directory, which is usually on a local machine. The P2P network does the rest: when a file search is conducted, it informs remote users of the file and provides services making it possible to download the file from the infected computer. There are also more complex P2P-Worms that imitate the network protocol of a specific file sharing system and responds positively to search queries; a copy of the P2P-Worm is offered as a match.Read more
Platform: Win32
Win32 is an API on Windows NT-based operating systems (Windows XP, Windows 7, etc.) that supports execution of 32-bit applications. One of the most widespread programming platforms in the world.Description
Technical Details
This worm spreads via file-sharing networks. The worm itself is a Windows PE EXE file approximately 1274KB in size.
Installation
Once launched, the worm causes the following error message to be displayed:
On repeated launched, the worm will cause the error message below to be displayed:
When installing, the worm copies itself to the Windows root directory as "microsoftscanreg.exe":
%Windir%microsoftscanreg.exe
It then registers this file in the system directory, ensuring that the worm will be launched each time Windows is rebooted on the victim machine:
[HKLMSoftwareMicrosoftWindowsCurrentVersionRun] "Microsoft Scanreg" = "%Windir%microsoftscanreg.exe"
Propagation via P2P
The worm checks to see if Kazaa is installed on the victim machine, and creates the following folder:
%Windir%scanregfilekazaaMy Shared Folder
The worm then copies itself to this folder under the following names:
Age Of Mythology FR CRACK.exe Alcatraz Fr Crack.exe Allopass + audiotel Keygen 2003.exe Arx Fatalis FR CRACK.exe Battlefield 1942 FR Crack.exe Clone CD 5 keygen.exe Delphi 5 fr crack keygen.exe Delphi 6 fr crack keygen.exe Delphi 7 fr crack keygen.exe Dreamweaver MX keygen + crack by orran.exe Fire-Works MX keygen + crack by orran.exe Flash MX keygen + crack by orran.exe Madden NFL 2003 FR CRACK.exe Mafia Fr Nocd.exe Medieval Total War Fr Crack.exe Mega-Serial Microsoft Macromedia Borland Photoshop.exe Nero FR 6 keygen + crack.exe No One Lives Forever 2 FR CRACK.exe Office XP fr Activation crack keygen.exe Photoshop FR 7 keygen + crack by orran.exe Sim City 4 FR Crack by zorio.exe Unreal 2003 Fr Nocd.exe Visual Basic fr 6.00 crack keygen.exe Visual fr c++ crack keygen.exe Visual.net fr Activation keygen crack.exe Winace fr 4 keygen crack.exe Windows XP Activation fr home Pro keygen 2003.exe Windows XP fr home et pro SP1 crack.exe Winrar fr 3.X keygen.exe Winzip fr 8.X keygen crack.exe
The worm modifies the configuration of Kazaa in the system registry so the resources which are shared by default will include the folder created by the worm:
[HKCUSoftwareKazaaLocalContent] "DownloadDir" = "%Windir%scanregfilekazaaMy Shared Folder"
This means that other Kazaa users will be able to access these files.
