Computer Systems and their Shortcomings
Well Psychotic wrote one of the most helpful unix text files in cyberspace but with the mail that we
received
after the release of our famous 36 page Unix Bible we realised that unix isnt for everybody so
we decided that we should write on another aspect of hacking.. Virtual Circuit and Psychotic is proud to
release, “Hacking Webpages With a few Other Techniques.” We will discuss a few various ways of hacking
webpages and getting root. We are also going to interview and question 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 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.
Thats 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, its shadowed.
Shadowed password files dont 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:
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 isnt 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 its nearly impossible to find a good cracker there
are a few ok ones out there. I recommend
that you look for Cracker Jack, John the Ripper, Brute Force
Cracker, or Jack the Ripper. Now for a dictionary
