Subject: 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...
