What is hardware hacking?

Price (@pricemcdonald) recently gave a hardware hacking talk at BSides Indy. Which I had the pleasure to attend. I was fascinated by the content he provided for the talk and decided to have him on. Hardware hacking is not something we see too much, but it is out there. It's used in physical penetration tests and for other learning opportunities. Listening to Price you can tell he has a strong interest in the topic.
