Vundo.downloader - New IFRAME Trojan Horse
http://vil.nai.com/vil/content/v_129972.htm

This trojan was recently installed via an HTML page
that contained the Exploit-IframBO trojan. It is
believed that the exploit code may have been mailed to
a large number of email addresses. Accessing the
exploit file results in vulnerable Internet Explorer
web browsers executing download code, which downloads
and executed Vundo.dldr. Vundo.dldr is a small trojan
that simply connects to a specific IP address to
download and execute another file. The trojan author
has built this trojan to download and execute the
Vundo trojan.
