I love how he explained this topic and showed just how easy it can be. He has a great point that humans can be the greatest weakness. People talk to strangers they find things to relate to others. Whether this is a common dog breed/name, or it is you grew up in the same city and never knew. People have started to protect their emails or passwords, but when posting, tagging locations, and gossiping that is not something that I believe is thought about. Everyone believes cyber attacks start and end online and this brings a whole new perspective into this.
