RE: [Full-Disclosure] Re: Outbreak of a virus on campus

["David Hale" <ddh@xxxxxxx>]

  We have currently blocked connections to port to/from 7000 on the
following hosts:

130.74.82.206
131.234.100.43
193.87.20.31

  This seems to have contained the spread of the worm within our campus. 
The list of hosts was gathered with a snort signature of:

alert tcp $HOME_NET any -> any 7000 (msg:"agobot IRC traffic";
content:"weednet";classtype:bad-unknown; sid:71727; rev:1;)

  Until the block was in place we had shut down around 50 hosts (mainly on
our dorm network) that had been infected with the worm.
