RE: [Full-disclosure] Tool Release - Tor Blocker

The purpose of this module is not to increase the security of your
server, but to allow you to prosecute hackers after the 
fact. If your server has a remotely exploitable vulnerability and you
block Tor nodes, you can still be hacked from any 
other IP address on the Internet.

The only difference is that blocking Tor force the attackers to use a
non-anonymized IP address, which can (at least 
theoretically) be traced back to them. I have doubts that this really
makes a difference in practice.

No see this, and the first sentence is where I think you're wrong. Tor
isn't such an age old thing, I guess the point all breaks down to how
many 'haxors' - that are tor users as well - would not use or be able to
use at least a couple of hops when communicating with the target. In my
opinion, whoever used tor in this case and rooted the webserver in
question probably knew the fact that he needed to go through some hops
and hide his identity - and if there wasn't tor (or in practice, maybe
before he ever used tor) he would have just set up non logging proxies
on a few hosts, or use a public proxy that was in china - if there
wasn't more money involved than (people help me out with this one)...
$5000(?), Jason still couldn't catch the hacker, so blocking tor
globally won't help the problem more than it hurts privacy towards legit
tor users.



Blacklisting IP addresses is no substitute for actually fixing the
vulnerabilities on your servers.

Right.
