Hacking Webpages
The Ultimate Guide
By Virtual Circuit and Psychotic

Well Psychotic wrote one of the most helpful unix text files in cyberspace but wi
th the mail that we recieved after the release of our famous 36 page Unix Bible w
e realised that unix isn't for everybody so we decided that we should write on an
other aspect of hacking..... Virtual Circuit and Psychotic is proud torelease, "
Hacking Webpages With a few Other Techniques." We will discuss a few various way
s of hacking webpages and getting root. We are also going to interview and quest
ion other REAL hackers on the subjects.

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 littleabout 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 par
t that gives you root. That's the main part of the file.

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

This is another example of a password file, only this one has one little differen
ce, 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
passwordfile:

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/uucicolisten: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 theyare disguised as an * as well.

Now that you know a little more about what the actual password file looks like yo
u should be able to identify a normal encrypted pw from a shadowed pw file. We ca
n now go on to talk about how to crack it.

Cracking a password file isn't as complicated as it would seem, although the file
s vary from system to system. 1.The first step that you would take isto download
or copy the file. 2. The second step is to find a password cracker and a diction
ary 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, B
rute Force Cracker, or Jack the Ripper. Now for a dictionary maker or a dictionar
y file... When you start a cracking prog you will beasked to find the the passw
ord file. That's where a dictionary maker comes in. You can download one from nea
rly every hacker page on the net. A dictionary maker finds all the possible lett
er combinations with the alphabet that you choose(ASCII, caps, lowercase, and num
eric letters may also be added) . We will be releasing our pasword file to the p
ublic 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 crack
er and follow the directions that it gives you.

The PHF Technique

Well I wasn't sure if I should include this section due to the fact that everybod
y already knows it and most servers have already found out about the bug and fixe
d it. But since I have been asked...
