Port 27347 concerns

["Joshua Levitsky" <jlevitsk () joshie com>]

Has anyone here captured any of this traffic? It's come up last week, but I didn't see anyone actually say they had a 
sample of the traffic or a honeypot they let get infected. Someone has to have a sample or a log they can share that 
has more detail than just blocking the attacker.

If you look at the table below you will see this is something building that will explode soon. 11/01 - Saturday is low 
because it is a weekend and less machines are on. The 11/02 - Sunday stats will be low as well I believe. 10/25 and 
10/26 you can see the same weekend dip. 

If on 10/24 we have 389 sources, and on 10/31 there are 709 sources then we should be well over 1000 sources by next 
Friday. This trend is concerning me because it could become very bad rapidly. Just don't want us all to be caught off 
guard by whatever this is. Some people seem to think it's a SubSeven trojan that has the port number flipped from 27374 
to 27347, but if it is then someone has a delivery mechanism that is working very well if you look at the table below 
which goes from 7 hosts to 709 hosts on Friday.
