I registered for PWB last October, after initial excitement, the terror of covering all pre-requisite started. So like almost everyone else I bought books. a lot of books. I learned python and web app development (udacity), I learned C and socket programming, Linux ASM, various tuts on security tube, Exploit-exercise.com etc

Now I am back and I want my OSCP. But before I sign up for the labs again there is one "little" topic which  I need to cover. Priv escalation! There are tons of resources abt exploitation but I can't for the life of me, find tutorial or books for priv esc. I would really appreciate some pointers regarding that. Hopefully that should minimize the pain in the labs this time around.

Cheers!
 

Best way to practice privilege escalation is to do it. Get a hold of vulnerable virtual machines like Kioptrix and De-ICE and root them. The PWB labs are also a great place to practice privilege escalation. The labs are for you to learn and make mistakes, so take advantage of that.

You may want to read this thread too (I originally made a typo in the title "eXcalation" as oppose to "eScalation")
