What is this?
This is my walk though of how I broke into pWnOS v1.
pWnOS is on a "VM Image", that creates a target on which to practice penetration testing; with the "end goal" is to get root. It was designed to practice using exploits, with multiple entry points
Scenario
A company dedicated to serving Webhosting hires you to perform a penetration test on one of its servers dedicated to the administration of their systems.
It's a linux virtual machine intentionally configured with exploitable services to provide you with a path to r00t.
What do I need?
BackTrack 4 (Final)
pWnOS.vmdk

Notes
I had problems with the Debian OpenSSH/OpenSSL exploit, some times it would work, else it would be really slow or just cant find the correct exploit file. The method which I use, turns it into a offline attack, which makes it more stealthy as it will not log failed logins (e.g. /var/auth/auth.log. See here for reading it). It relies on the default path tho!
This is one method of getting in, the author did say that there is multiple ways in!
It took me a bit of work to also to get it to work with virtual box & static IP addresses.
That's all! See you.
