I just received a couple of infected messages.

The sender is listed as "agoodwin" and the subject relates to hose reels. If you see something like this, don't open it.

If you don't have virus protection, get some soon. Viruses like this can work even if you don't open the e-mail

Payload:
Large scale e-mailing: Spreads usingmIRC

Modifies files: Modifies autoexec.bat and HTML, HTT, HTM files
Distribution

Shared drives: Copies itself to the shared folder of KaZaA.

VBS.Pelic.Worm spreads using mIRC channels by adding a line to the Script.ini file.

If the worm is running, when you joining a chat channel, the script displays the message

hola , soy francisco , quieres tener todas las peliculas que quieras ver!

English translation: "Hello, I am Francisco. Do you want to have all of the films that you want to see?"

It then creates a file named C:\Windows\All_acces_videos.exe.vbs.

When the worm runs, it creates copies of itself as:

C:\Windows\autoexec.bat.vbs
C:\Program Files\KaZaA\My Shared Folder\Sex-free.exe.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Windows-xp-full-edition.exe.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Shakira-sex-anal.jpg.vbs
C:\Program Files\KaZaA\My Shared Folder\Mix-brazil.mp3.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Porto-seguro.mp3.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Asereje.mp3.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Quake 2.exe.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Half-life_complete_version.zip.vbs
C:\Windows\Quake2.exe.vbs
C:\Windows\all_acces_videos.exe.vbs
C:\Windows\kazaa\all_acces_videos.exe.vbs
C:\Windows\kazaa\sex_all.exe.vbs
C:\Windows\kazaa\quake2_full_version.exe.vbs

NOTE: These paths are hard-coded.

The worm searches for major antivirus programs and attempts to delete files in the program's folder.

The worm modifies Autoexec.bat by adding the lines:

@Start C:\windows\Quake2.exe.vbs>nul
cls

It then searches drives C, D, and E for mIRC scripts to infect. If mIRC is installed on any of these drives, the script modifies Script.ini to send a copy of the worm to other users via mIRC.

It creates the registry key

HKEY_CURRENT_USER\software\Legion\sistem

and adds the value

infected

If this value is set, the worm overwrites .html, .htt, and .htm files with its code.

The worm also alters the KaZaA sharing registry key

HKEY_CURRENT_USER\Software\Kazaa\LocalContent\Disa
bleSharing

which is set to

00000000

Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":

Turn off and remove unneeded services. By default, many operating systems install auxiliary services that are not critical, such as an FTP server, telnet, and a Web server. These services are avenues of attack. If they are removed, blended threats have less avenues of attack and you have fewer services to maintain through patch updates.
If a blended threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services.
Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
Configure your email server to block or remove email that contains file attachments that are commonly used to spread viruses, such as .vbs, .bat, .exe, .pif and .scr files.
Isolate infected computers quickly to prevent further compromising your organization. Perform a forensic analysis and restore the computers using trusted media.
Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.


NOTE: These instructions are for all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.


1. Update the virus definitions.
2. Run a full system scan, and delete all files that are detected as VBS.Pelic.Worm.

For details on how to do this, read the following instructions.

To update the virus definitions:
All virus definitions receive full quality assurance testing by Symantec Security Response before being posted to our servers. There are two ways to obtain the most recent virus definitions:
Run LiveUpdate, which is the easiest way to obtain virus definitions. These virus definitions are posted to the LiveUpdate servers one time each week (usually Wednesdays) unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, look at the Virus Definitions (LiveUpdate) line at the top of this write-up.
Download the definitions using the Intelligent Updater. Intelligent Updater virus definitions are posted on U.S. business days (Monday through Friday). They must be downloaded from the Symantec Security Response Web site and installed manually. To determine whether definitions for this threat are available by the Intelligent Updater, look at the Virus Definitions (Intelligent Updater) line at the top of this write-up.

Intelligent Updater virus definitions are available here. For detailed instructions on how to download and install the Intelligent Updater virus definitions from the Symantec Security Response Web site, click here.

To scan for and delete the infected files:
1. Start your Symantec antivirus program, and make sure that it is configured to scan all files.
Norton AntiVirus consumer products: Read the document How to configure Norton AntiVirus to scan all files.
Symantec enterprise antivirus products: Read the document How to verify a Symantec Corporate antivirus product is set to scan All Files.
2. Run a full system scan.
3. If any files are detected as infected with VBS.Pelic.Worm, click Delete.
