Possible large botnet

["Pablo Esterban" <pablo_esterban () hotmail com>]

Seems to be a botnet forming with the help of exploiting the recent wmf flaw 
on the following site. AFAIK malware/adware is referencing this.

This injects a trojan connecting to 219.240.142.59 on port 44234

44234/tcp open     irc          Unreal ircd
47292/tcp open     irc          Unreal ircd
47296/tcp open     irc          Unreal ircd
54729/tcp open     irc-proxy    psyBNC 2.3.1

Channel stats list around 500 bots and around 1200 connected (may or may not 
be accurate), however if you poke around you will find 
http://219.240.142.59/usage/, containing some interesting links and info 
about when this most likely started.

The tcp stream below demos the login, and calling of 
http://219.240.142.59/ppp/mediax.dll. Stats for January list close to 90k 
hits on this particular file(!).
