Subject: Fw: [Unpatched] The Bizex worm

there's more info at http://www.daemonology.net/ICQworm/worm.txt

It seems it uses the nearly 2 years!! old "icq downloads stuff to a known
location" vulnerability
http://www.derkeiler.com/Mailing-Lists/securityfocus/bugtraq/2002-07/0210.html

Recently made current by Arman Nayyeri, as you can see his post also
mentions icq as an attack vector
http://www.securityfocus.com/archive/1/348521

which they also use, effectively making this a worm that explots a zero day
vulnerability, no patch is available from eighter microsoft or icq, and
antivirus signatures are trivially defeated. So it's easy to make variants
to this virus

Shame on ICQ!

> Dear Unpatched subscriber,

> Today a new worm was discovered in the wild, called Bizex. Employing a
> multilayered attack, spread and infection approach it spreads through
> several vulnerabilities and exploits in multiple technologies such as
> email attachments, ICQ instant messaging and HTTP web pages. Some of
> these vulnerabilities are without patches from the vendor, raising the
> level of potential damage.
>
> Kaspersky is currently labelling this a global epidemic with more than
> 50.000 infections just among ICQ users.
>
> Likewise, implementing multiple layers of defense can help mitigate the
> threat posed by multilayered worms such as Bizek. The currently
> available BETA version of Qwik-Fix completely protects against the Bizek
> worm by mitigating the impact of several vulnerabilities it relies on.

> PivX Solutions are currently researching the potential impact of Bizex

>
> Microsoft Java virtual machine class loader
> ICQ SCM local file planting
> Microsoft Help CHM vulnerabilities
> ADODB Stream
> Internet Explorer Shell Folders
>
> Interestingly, the shell folder vulnerability was only recently

> It has been linked to websites that are anonymously registered to
