This lecture offers a new spin on social engineering - by staring with fundamental psychological flaws in the human brain, and discussing how they can be exploited. Also known as "hacking in meat space". The second part of this lecture covers physical security, with illustrative animations of how locks and lockpicking work. Defenses against lockpicking are discussed. Finally the third part of this lecture discusses various techniques attackers can use against your systems once they have physical access. This includes hacking over power lines (physical access to just power sockets), USB/PS2/LAN commercial tools, and building automation control systems network hacking.
