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 to release, "
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 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 par t 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 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 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
