About the choice of distribution, you can pretty much use whatever you want. (I didn't use BackTrack, but I had to install some tools completely on my own, but that was just fun for me none the less.)
Ok,
I am almost down going through the videos. My goal was to have an idea of the course materials (what I call, the first pass).
I notice that all exploit development is done against 32 bits Windows XP or Vista.
So my question is: To get ready to the OSCE exam, do I need to learn:
1) Exploit development on 64 bits Windows OS?
2) Exploit development on Linux, Unix, *BSD?
I am planning on practicing these two points pretty soon anyway, but since I am focusing on the exam, I am trying to scope my study right now...
Thanks!
1) Unlikely.
2) Unlikely, but knowing how exploits works on almost all types of systems is a good idea :-)
