Swen/Gibe.F Worm - Some New Info (was RE: Web counter in the new Swen/Gibe.F worm)

LoL. Just found the worm even has a nice GUI! (I am
attaching a sample extracted resource of a dialog)

Once executed, it presents installation dialogs to the
users (with EULA and all) and installs as a legitimate
program/patch would install. It doesn't try to be
discreet in any way.

The malicious message to which this worm was attached
posed as a *very* convincing MS patch. 

The author probably thinks it's better to ask users
directly for info, posing as a legitimate program,
than try to be discreet in its function(See attached
text). This way it tries to exploit certain
assumptions that users have about
malware(sneaky,encryted,packed,no nice GUI :),etc). I
think lots of people, otherwise paranoid and careful,
will fall for this worm. Believe me, Swen *very*
convincingly upsets users' assumptions and this is its
biggest USP...

Hi,

Joe Stewart of Lurhq.com has made an interesting
discovery about the new
Swen/Gibe.F worm that started circulating today: 
When the worm infects
a new machine, it hits a Web counter.

The URL of the counter is:



http://ww2.fce.vutbr.cz/bin/counter.gif/link=bacillus&width=6&set=cnt006

If this URL wraps in your email reader, here's a
shorter version:

   http://tinyurl.com/nufo

At 2:30 EST, the counter is about 615,000.

Here's a bit more about the worm:

   http://news.com.com/2100-7349_3-5078696.html

The server log entries for this counter might prove
interesting to virus
researchers.  These entries could provide data for
a statistical study
of computer worm transmissions.  Perhaps the
Vutbr.cz Web site would be
willing to go public with this information.

Is anyone storing sample virii somewhere for
analysis? Or do we have to 
wait for it to show?
