Re: Denial of service attacks apparently from UUNET Netblocks

I would not be surprised if the caller's phone number were logged, most
modern modem banks talk ANIS and DNIS, which if I'm remembering correctly
is basically caller ID.  I'm thinking of putting this on our POP, as there
doesn't seem to be an extra charge to get the data from the telco.

I would have to disagree, in Canada anyway, the telco charges extra for these features, andand while
the modemracks will support it few if any ISP are gonna spend the $$$ for it. 
Until of course they are attacked and loose business and then the VP's the cost
of NOT having it.

S'okay.  Have the feds subpoena UUNET for the connect logs for these
max'es.  UUNET keeps the logs and is capable, given the exact time of the
attack(s), of going through the logs, identifying exactly who it was, and
if it's one of their customers, giving the personal info to the feds.
If it's a reseller's customer, they can get the user info and forward it to
the reseller and inform the feds who they need to talk to for the personal
info.  Whoever it was is as good as nailed.

Unless it was a stolen account.  With more and more "naive" users coming
online, the chance of this kind of thing happening is greater and greater.
You can shut off the account.  Feds can visit the home of whoever owns the
account.  They can even be blocked from ever getting any account at any
ISP for life.  But if this possibility is fact, you won't have the perp
and they can attack again.

Now if the telco has records of all the phone calls you can find out where
the calls actually came from.  Maybe that's the perp.  Maybe not.

What is ultimately needed is some better real time detection of this kind
of thing sufficiently deployed so that it is present on all routers where
the exposure exists.  You may not catch the perp, but you might reduce the
damage it causes.

How to encourage this to be done is left as an exercise for the reader.
