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

It has come to our attention that the majority of tor users are not actually
from china but are rather malicious hackers that (ab)use it to keep their
anonymity. We have released a tool to stop users from utilizing this tool to
protect their identity from prosecution by a designated systems
administrator. Otherwise this puts the administrator in responsibility for
any malicious actions caused by said user. Forensics is left with a tor exit
node.                                                              

Recently our servers were hacked by a tor user and we were unable to
prosecute due to not being able to trace the source as the user was using
this malicious piece of software to keep his/her anonymity. 
                                                                 
To mitigate most tor attackers we've written an apache module designed to
give tor users a 403 error when visiting a specific website.  We suggest all
administrators whom do not wish a malicious tor user to visit and possibly
deface their website to enable the usage of this module. This may not get
all attackers, but hopefully it raises the security bar just a little bit
more to safeguard ourselves from hackers.

Thanks.
