Re: Hacking AS400

Satya,

Most of the AS/400 boxes I have audited contained default usernames and
passwords. When a new profile is created on OS/400, the default password
assigned is the profile name.

Combine this with the fact that ftp, telnet, pop services provide you with
useful information about existing profiles, and you will get a valid profile
on the os/400 quite easily. (It will give you a different error message if
the account exists but you tried logging in with a wrong password, than if
the profile does not exist on the system).

Shalom Carmel has written an excellent book on iSeries hacking and he has
also give presentations on blackhat (or will  give ...) about hacking
os/400. Google is still your best friend ...

Hope this helps
