hi ya

hey.. that's my idea too .. at least to provide level-1 
first defense against script kiddies ...
        move su, tar, make, gcc, mail, too ... very important

it wont necessarily discourage them... their script and
attack will be deposited ... but the scripts wont be able
to continue to "call home" for further info about what 
to do next... like d/l more attack codes etc

when that initial script does get installed on your box,
you better fix that pupppy asap before the come back in
again ... ( find out the exploit they used to gain access
in the first place )

one of the boxes ( that they didnt want touched ) did get
hit with the slapper wormlast week .. but it didnt do much
else since the binaries was missing
        - so now their boxes was updated/patched no matter
        how hard they prevented me from updating it...
        ( and in the process,,, printer services died..
        ( lpd got replaced w/ LPrng but that was fixable
        ( and no data loss due to [cr/h]acker etc

Bottom line, just have a tripwire installed/configured and you'll "have" them by dinner. Maybe they think "hey its 
so simple that they wont even see it or bother to remove it", who knows..

Assuming you have 'em. What then ? Sue them ? afaik they have to be
caught _in the act_ .A few days ago i saw a policeman searching a
windows machine for logs regarding Credit Card fraud. He searched in "My
Documents" and that was that. Well, i ask you gents.. how would that man
tell the difference between a "l33t h3x0r" DDOS-ing and a peaceful
BitchX user ? (both sittin' next to one another with putty sessions
open). 
About tripwire... i don't have the patience to setup tripwire on a P1
90Mhz 16Mb RAM. A guy gave a better idea on another list. Simply mv
wget,ftp,lynx and all regular progs used by skiddies sumplace else and
that would discourage them a bit (i find the situation rather amusing
myself).
