I recently started a YouTube series on hacking. With a main focus on reverse engineering and memory corruption. I'm currently on episode 0x5 and I currently release them biweekly.

I also record myself playing CTFs and I just created a video walkthrough of the pwnable 200 challenge from the 32c3 CTF: https://www.youtube.com/watch?v=wLsckMfScOg

Maybe it helps somebody.
