Can anybody outline exactly how this security hole works?  I've had a couple
of FTP and Web sites suggested and one seems to have a program that will break
the security on a PIC chip, but it has no source code, so I have no idea
what it's doing.

I assume that anybody who wishes to compromise the security on a PIC chip
for nefarious purposes already knows how to do it, so no cats will be let
out of the bag by divulging the general method here.
