Security expert and diabetic Jerome Radcliffe has hacked into the wireless insulin pump he wears on his body around the clock to keep his blood sugar level stable. Radcliffe talked about the hack in a presentation at the Black Hat Security Conference, held in Las Vegas. He reportedly detailed how untraceable attacks could be launched against wireless insulin pumps, pacemakers and implanted defibrillators from a distance of half a mile. It's possible to hack any wireless medical device that's not configured properly, Tim Gee, principal at Medical Connectivity, told TechNewsWorld.
