I don’t get why someone would want to spend the time creating a method of hacking something as important and life sustaining to some people as an insulin pump. To diabetics that rely on the insulin pump for their lives hacking it and changing the dose of insulin could kill them. At the Black Hat Security conference a man named Jay Radcliffe showed off this hack. He is a diabetic and depends on an insulin pump and a glucose monitor to live. Radcliffe says that he has reverse-engineered the proprietary wireless communication system between the glucose meter and the pump.
