I agree about ³killing² any inbound traffic from the APNIC IP space. For
any of you who may not know (newbies) the APNIC is the Asia Pacific Network
Information Center and can be reached at: http://www.apnic.net That
organization is attempting to keep a ³handle² on the Asia-Pacific IP Space,
but unfortunately, time-after-time APNIC space is used to launch attacks.
At one time, I was working for Harris Corporation, and I was managing the
network of a large US Air Force installation. This was during the early
days of ³SNORT². The amount of ³crapola² coming out of the APNIC IP Space
was unbelievable. Once I set up a SNORT system and was able to pinpoint it,
I received permission from the Base Commander to BLOCK all of the APNIC
space at least ³inbound² anyway. At one time, I think APNIC IP Space was
responsible for more than 65% of the ³Internet NOISE² out there at any given
time. Take a look at the Internet Storm Center over at SANS and you¹ll see
what I mean: http://isc.sans.org
I hate to ³pick on² the APNIC, but most of the ³government-Sponsored²
hacking comes out of that region unfortunately. All we can do in the rest
of the world is be aware of it and take appropriate measures.

Coop

Subject: Re: Some new SSH exploit script?
All,
Similarly, I have a large number of hacktards trying to login as root on
my servers.
I also have no need for apnic space to talk to my servers, most of my
legitimate requests come from the US.
As such, I have a script that I wrote that I call killapnic, that goes
out to the web, retrieves the apnic space and ipfw's all of it.
I have had great success with this. While it doesn't stop the local
hackers, it does stop 95% of the cruft that comes my way.
I suppose if I could adapt my script to do both this, and nailing out 3
bad attempts from x ip. This seems trivial.
