Deviant Ollam's talks are always first class. I also love this one, about physical pentesting in general:

This is one of my favourite talks ever. I couldn't have given less of a shit about the topic and wasn't expecting to watch more than 5 minutes of it. Nek minnut the video is ending and I wanted another hour of it haha.

Look for "This key is your key, this key is my key" by the same pair. It's basically that.
