Earlier this month, Jay Radcliffe, a computer security professional who is also diabetic, showed how an attacker could remotely control insulin pumps to deliver too much or too little insulin to the individual wearing the device. “My initial reaction was that this was really cool from a technical perspective,” Radcliffe told the Associated Press. “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.” He noted that many other medical devices that use wireless communication and allow for remote-control access could have the same vulnerabilities.
