"The Breaking of CyberPatrol 4"

A couple of hackers decided to see how CyberPatrol's "sophisticated anti-hacker
security" actually measured up... it came up very short. :)

-----

Abstract

Several attacks are presented on the "sophisticated anti-hacker security" 
features of Cyber Patrol® 4, a "censorware" product intended to
prevent users from accessing Internet content considered harmful. Motivations, 
tools, and methods are discussed for reverse engineering in general and reverse 
engineering of censorware in particular. The encryption of the configuration 
and data files is reversed, as are the password hash functions. File formats 
are documented, with commentary. Excerpts from the list of blocked sites are 
presented and commented upon. A package of source code and binaries implementing 
the attacks is included.
