Semi-OT: responding to attempted breakins

2006-05-03 Thread Robert Huff

As a result of installing new bits on my system, and paying
attention to old ones, I've noticed several attempted break-ins
which I currently believe have been unsucessful.
As I have the appropriate log files, I'd like to contact the
administrators and ISPs for the systems involved.  Can someone
recommend a good response boilerplate - something that's concise,
informative, professional, friendly, and yet firm?

I'm sorry I can't. I did, however, want to interject my two cents
here ;-). From a non-professional (i.e. student) viewpoint, it's been my
experience that if I take the time to write a polite email, which
includes relevant bits from my log files, to the admin for the IP in
question asking them to look into it, they will usually take care of it.

I suppose the appropriate response to this sort of situation depends on
what your hosting. I run a web-server and SSH gateway for personal use,
so although extremely annoying, it wouldn't be any big loss for me if it
was cracked. 

I suppose you could always blacklist the domain in question, and see how
long it takes for anyone to complain ;-).\

I've been pretty religious about responsible reporting for about 6 
months now, reporting all ssh (and recently FTP) attacks to the 
originating ISP.


If I may, allow me to infer from your desire to be firm that you would 
like to cause the behaviour stop, and to give you a piece of advice.  I 
believe that you will be very unhappy if you are reporting for that 
reason.  The attacks, probes, tests, attempts - all of them - aren't going 
to stop, except by filtering those packets out through one mechanism (a 
firewall) or another (disconnecting your 'net connection).  You will end 
up bailing water with a teaspoon.
