A security researcher who is diabetic has identified flaws that could allow an attacker to remotely control insulin pumps and alter the readouts of blood-sugar monitors. As a result, diabetics could get too much or too little insulin, a hormone they need for proper metabolism.

Jay Radcliffe, a diabetic who experimented on his own equipment, shared his findings with The Associated Press before releasing them Thursday at the Black Hat computer security conference in Las Vegas.

“My initial reaction was that this was really cool from a technical perspective,” Radcliffe said. “The second reaction was one of maybe sheer terror, to know that there’s no security around the devices which are a very active part of keeping me alive.”

Increasingly, medical devices such as pacemakers, operating room monitors and surgical instruments including deep-brain stimulators are being made with the ability to transmit vital health information from a patient’s body to doctors and other professionals. Some devices can be remotely controlled by medical professionals.

Although there’s no evidence that anyone has used Radcliffe’s techniques, his findings raise fears about the safety of medical devices as they’re brought into the Internet age. Serious attacks have already been demonstrated against pacemakers and defibrillators.

I hear their next competition will be to see who can use a wifi nursery monitor to electrocute an infant.
