I opened a trouble ticket with a major ISP in the USA about a Smurf
originating at one of their customer nets targeted at me. I gave them the
URL about Smurfing just in case they never heard about it.
This is the email I got after 8 hours from their NOC:
***Note #1 03-20-1998 08:51:05 GMT Author: arsmith
More info. requested
Please send any samples along with the following info ASAP...
1. Is it presently still going on ?
2. Was your site used as a launching point for attacks on other entities ?
How does one send "samples" of a Smurf (I gave them the originating IPs,
destination IP, time, frequency, pkt size, etc.)? If this is how major ISPs
handle Smurf storms, we can expect much more congestion. It is as if the
ISP NOCs assume Smurf is Spam!

What he means is that you should probably include Smurfette as a sample.

When BBN's NOC handed one to our NOC yesterday, or was it the day before,
they sent a cut and paste of
o configuring their edge cisco to detect and log
o the log
which both documented the problem and, if our NOC did not have smurf clue,
gave a clue on how to track.
[ aside: it was tracked to the perp and stomped ]

Hi
I'm looking to put together a page with every NSP's networking utilites. I
have seen several traceroute, ping, BGP utility url posted here. Can
anyone repost or point me to a listing of those?
thanks

Last weekend we had one host on our network as the target of a smurf
attack. When I reported it to both our upstreams (UUNet and Time Warner
who reported it to MCI), we got two stories. MCI, whom I'm not even a
direct customer of started tracking the attack as soon as they were
informed. UUNet took an hour to get a security person on the phone who
then told me that there was nothing they could do, period.
My question is this: When will UUNet have security types on duty 7 days a
week, and will said people be clueful enough to track this sort of thing
down? I told the people at UUNet that we were under smurf attack, and
then I had to go through a 10 minute explanation of what a smurf attack
was and what it was doing. I would expect a worldwide NSP to keep up with
things like this, especially when a regional like myself can.
I had logged all ICMP traffic coming into our network via an access list,
and could give them all the information they needed to get to the
offending networks, so it's not like they had such a hard job ahead of
them.

If you call UUNet after hours, they have to page someone from security.
Depending on which grunt answers the phone, you may have to remind them
several times that you're experiencing a Dennial of Service ATTACK, and
that they NEED to page the on-call security person. Some of their first
level people are good, but some seem like they were just pulled in off the
street and handed a phone.

It's even funnier when you explain to the first level person that a host
on your network is being smurfed, and they act as if they know exactly
what you're talking about. Then they ask "Can you give me the address the
attack is coming from?" Then they admit they have no idea what smurf is.
Lately, UUNet's been very slow to track smurf attacks, claiming they can't
use DoStracker because it "does bad things to [their] routers". Having
never used it myself, I have no idea if this is true or just a line.
The best you can hope for is to get a security person on the phone and
have them put in a temporary filter.
UUnet and Alternet seem to carry a large amount of the smurf traffic as it
migrates
down the line, it would seem the responsible thing to do is have network
security
to track and log and trace source locations on its out of country backbones
where
these attacks stem from....need I get more clueful?
