Hacking Webpage Exploit

Hacking Webpage Exploit
Getting the Password File Through FTP

Ok well one of the easiest ways of getting superuser access is through
anonymous ftp access into a webpage. First you need learn a little about
the password file...

root:User:d7Bdg:1n2HG2:1127:20:Superuser
TomJones:p5Y(h0tiC:1229:20:Tom Jones,:/usr/people/tomjones:/bin/csh
BBob:EUyd5XAAtv2dA:1129:20:Billy Bob:/usr/people/bbob:/bin/csh

This is an example of a regular encrypted password file. The Superuser is
the part that gives you root. That's the main part of the file.

root:x:0:1:Superuser:/:
ftp:x:202:102:Anonymous ftp:/u1/ftp:
ftpadmin:x:203:102:ftp Administrator:/u1/ftp

This is another example of a password file, only this one has one
little difference, it's shadowed. Shadowed password files don't let you
view or copy the actual encrypted password. This causes problems for the
password cracker and dictionary maker(both explained later in the text).
Below is another example of a shadowed password file:

root:x:0:1:0000-Admin(0000):/:/usr/bin/csh
daemon:x:1:1:0000-Admin(0000):/:
bin:x:2:2:0000-Admin(0000):/usr/bin:
sys:x:3:3:0000-Admin(0000):/:
adm:x:4:4:0000-Admin(0000):/var/adm:
lp:x:71:8:0000-lp(0000):/usr/spool/lp:
smtp:x:0:0:mail daemon user:/:
uucp:x:5:5:0000-uucp(0000):/usr/lib/uucp:
nuucp:x:9:9:0000-uucp(0000):/var/spool/uucppublic:/usr/lib/uucp/uucico
listen:x:37:4:Network Admin:/usr/net/nls:
nobody:x:60001:60001:uid no body:/:
noaccess:x:60002:60002:uid no access:/:
webmastr:x:53:53:WWW Admin:/export/home/webmastr:/usr/bin/csh
pin4geo:x:55:55:PinPaper Admin:/export/home/webmastr/new/gregY/test/pin4geo:/bin/false
ftp:x:54:54:Anonymous FTP:/export/home/anon_ftp:/bin/false

Shadowed password files have an "x" in the place of a password or sometimes
they are disguised as an * as well.

Now that you know a little more about what the actual password file looks like
you should be able to identify a normal encrypted pw from a shadowed pw file.
We can now go on to talk about how to crack it.
Cracking a password file isn't as complicated as it would seem, although the
files vary from system to system. 1.The first step that you would take is to
download or copy the file. 2. The second step is to find a password cracker and
a dictionary maker. Although it's nearly impossible to find a good cracker there
are a few ok ones out there. I recomend that you look for Cracker Jack, John the
Ripper, Brute Force Cracker, or Jack the Ripper. Now for a dictionary maker or
a dictionary file... When you start a cracking prog you will be asked to find
the the password file. That's where a dictionary maker comes in. You can download
one from nearly every hacker page on the net. A dictionary maker finds all the
possible letter combinations with the alphabet that you choose(ASCII, caps,
lowercase, and numeric letters may also be added) . We will be releasing our
pasword file to the public soon, it will be called, Psychotic Candy, "The Perfect
Drug." As far as we know it will be one of the largest in circulation. 3. You then
start up the cracker and follow the directions that it gives you.
