Overview

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Characteristics

This VBScript virus code contains errors and some payloads will not be executed.  The virus code is encrypted and on executing the infected script, the virus will copy itself to the hard coded directory: c:\windows\alias.jpg.vbs .  It will also copy itself to random network drives as [random character]alias.jpg.vbs. Example Falias.jpg.vbs. The virus also attempts to copy itself to random IP sites. 

The following registry key will be added:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
  Run "Gnsys" = C:\windows\alias.jpg.vbs

VBS/Lucave contains mass mailing capabilities, IRC propagation and also utilizing the Windows Management Instrumentation (WMI), but this is not executed due to the error in the virus code.

Symptoms

The presence of the file alias.jpg.vbs in the hardcoded directory c:\windows or in the root directory on network drives.  

Method of Infection

Executing the infected VBScript .

Removal

Use current engine and DAT files for detection and removal.

Using File Filtering with WebShield SMTP for WindowsNT(not applicable for Solaris):
Within the Configuration console select content filtering.
Select Add.
Add a Description for the content filter rule such as VBSBlock.
Select Filter on Attachment File name.
Filter on .vbs
Select OK.

Additional Windows ME/XP removal considerations

* Office2000 Updates

* scriptlet.typelib/Eyedog vulnerability patch

* Outlook as an email attachment security update

* Exchange 5.5 post SP3 Information Store Patch 5.5.2652.42 - this patch corrects detection issues with GroupShield
