smurf attack

  • From: Jon Lewis
  • Date: Mon Dec 07 02:49:08 1998

FDT was on the receiving end of a roughly 1 hour smurf attack this
evening.  I'm told it was probably something to do with the takeover of
some gay related IRC channels and that the attack was not isolated to FDT.

This has me really thinking again that someone needs to start up a
blackhole BGP feed (similar to the MAPS RBL) for the purpose of annoying
smurf-amp networks into cleaning up their nets.

Below is a list of networks (assumed to be /24's for convenience) and the
number of unique IPs seen sending echo replies in each network during a 5
minute sample of the attack.  It should be noted, most of these networks are
likely to be far worse smurf amps than suggested by my numbers.  Now that I
think about it, it's obvious.  Both our T1's to the net were totally filled
by the attack, so lots of packets didn't get through.  I've clipped all the
nets showing only 1 host...but it's likely some of them really were smurf
amps.  The last one on the list, 200.130.98.0, for which I only saw 2 unique
addresses in my tcpdump now results in:

2 packets transmitted, 2 packets received, +47 duplicates, 0% packet loss

Anyway...if these are your networks, clean them up before you get
blackholed.  I'll go and feed this list through my script that registers
nets with www.powertech.no/smurf/ now.

These are the hosts that took part in flooding FDT with icmp echo replies. 
Being listed here does not imply that your network is a smurf amp, but might
help you track things down if you have smurf amp subnets.  Even if your
network only participated in a 1:1 ratio, you are listed here if you showed
up in the 5 minutes I logged.
