Trojan Horse, Worm
Systems Affected:

W32.Myparty@mm is a mass-mailing email worm. This worm is capable of spreading itself only between January 25, 2002, and January 29, 2002. However, it remains active on infected computers after this period of time.

It has the following characteristics:

Subject: new photos from my party!

My party... It was absolutely amazing!
I have attached my web page with new photos!
If you can please make color prints of my photos. Thanks!

Attachment: www.myparty.yahoo.com

The worm sends email to all contacts in the Windows address book and to email addresses that it finds in the Outlook Express inboxes and folders. In addition, the worm sends a message to the author so that the author can track the worm.

On Windows NT/2000/XP-based computers, the worm drops a backdoor Trojan that allows a hacker to control the system. Norton AntiVirus detects this as Backdoor.Myparty.

Finally, if the file name of the worm is Access.<any extension>, it may launch the Web browser to http:/ /www.disney.com. However, the worm does not contain code which can generate a file with the name Access.<any extension>, so it is highly unlikely that this will trigger.
