Cisco Password Bruteforcer Exploit
Code:
/*
.: free source :. .: coded 4 Avatar Corp :.
enabler.
cisco internal bruteforcer.
coder - norby
concept - anyone
this program just logs into a CISCO router and tries a list of
passes looking for the enable one.
it works in password-only CISCO as well in login-pass ones and
has been succesfully tested on many 2600 and a few 12008.
the prog's concept [bruteforcing a router for gaining enable access]
is quite simple ...how amazing I haven't seen similar progs before!
anti eleet&0day force 
anyway... information wants to be free 
sciao belli

neural collapse _ i truly hope in this project
v1 02/10/2k+1
todo for v2: use of threads, implement a passlist recovery
(very simple feature)
