VBS.Gaggle.E@mm

VBS.Gaggle.E is a variant of VBS.Gaggle.D. It is a mass-mailing worm that overwrites several files.

This worm can infect the following file types:

• .vbs
• .vbe
• .js
• .jse
• .hta
• .htm
• .html
• .php
• .shtm
• .shtml
• .phtm
• .phtml
• .mht
• .mhtml
• .plg
• .htx

The worm retrieves the email addresses from the files that have .hta, .htm, .html, .php, .shtm, .shtml, .phtm, .phtml, .mht, .mhtml, .plg, or .htx extensions. Then, it uses its own SMTP engine to send email to all the email addresses that it finds. The worm can also spread through ICQ, and some file-sharing networks.

The From field of the email is spoofed, the subject line and message vary, and the attachment is Filezip.zip.
