I think the other side is that the antisocial types won't have a lot of trouble
getting their hands on the code in any case, and it only takes a few of them
to wreak havoc.  The advantage of distributing the code is that it may shock
some users and system managers into defensive action; this cracking method
depends, after all, on the presence of stupidly chosen passwords.  At our
(UNIX) site we have taken the obvious precaution of tuning the password
mechanism to forbid passwords that can be found in the commonly available
on-line dictionaries.  All sites should, at a minimum, do likewise.  Forthwith.
