A little update for the news:
Aliases:VBS/VBSWG-X, VBS.HomePage, VBS.VBSWG2.D@mm, VBS/SST.gen@MM, 
I-Worm.Homepage, VBSWG.X, Home Page
Variants:    N/A
Attachments:    homepage.HTML.vbs
Discovered:    05/08/2001
Distribution:    High
Severity:    Moderate to Severe (may crash email servers)
Vulnerable:    Microsoft Windows; Microsoft Outlook
Profile Updated:    06:15 PM GMT 05/09/2001

Symptoms
One of four possible adult web sites is displayed as the default home page 
on the affected computer (omitted from description).

Infection
Once the infected attachment is executed Homepage drops a copy of itself 
into the Windows temporary directory as "HOMEPAGE.HTML.VBS."

As part of it's mass mailing routine, HomePage checks the following registry 
entry to see if it has already performed a mass mailing on the affected 
machine:


HKEY_CURRENT-USER\Software\An\Mailed

If the above value is set to 1 the worm has already performed a mass mailing 
on the affected machine. If the above value is NOT set to 1, Homepage sets 
the value and attempts to mass mail addresses within the Outlook Address 
book on the local machine, with the data noted above in the Description 
field. Once the mass mailing is completed, Homepage searches Microsoft 
Outlook Journal and Sent folders to delete emails with the subject of 
"Homepage", in an attempt to conceal it's mass mailing and presence on the 
affected machine.

If Microsoft Outlook or Windows Scripting Host (WSH) is not present on the 
system Homepage is unable to propagate.

After the mass mailing, Homepage attempts to change the default home page of 
Internet Explorer to one of four possible adult commercial web sites 
(omitted from description).

Payload
Mass mails addresses within the Microsoft Outlook address book. May be 
prolific enough to cause email servers to crash. Default home page of 
Internet Explorer may be change to one of four possible adult web sites.

Disinfection
Use updated antivirus software to remove this malware from an infected 
machine. Esafe has provided a free cleaning utility for Homepage.

While not recommended, users may attempt to manually remove this malware 
from their machine by doing the following:

Remove any occurrence of "HOMEPAGE.HTML.VBS" from all media.

Delete any emails with the subject "Homepage" or the "HOMEPAGE.HTML.VBS" 
attachment.
Perform a backup of the registry and then remove the registry key from 
Homepage if present, HKEY_CURRENT-USER\Software\An\Mailed.

Remove Windows Scripting Host from machines that do not require it for 
normal operations to lower the risk of infection from malware.
