This really doesn't sit well with me on multiple fronts: "Company technicians were able to replicate Radcliffe's findings, confirming that a hacker could order the pump to dose insulin from a distance of up to 25 feet, Levy said. He said such attacks are difficult to pull off because they require specialized technical expertise and sophisticated equipment." Specialized technical expertise and sophisticated equipment? Based on what I just read from the product manual, this attack appears to be capable of being done with two HackRF's since none of the frequencies used by this device exceeds 2.4 Ghz. Is a HackRF really as "specialized" as what is being implied by the manufacturer? Further, I get it, I've used GNU Radio. It's not easy, but it's also not terribly difficult to pickup. Yes, if someone wanted to kill someone with an attack on an insulin pump like this, there are likely easier ways, but ultimately, for anyone that has any reasonable level of technical ability, developing an attack against the system isn't much of a barrier and would leave little trace - certainly none that would likely lead to a murder conviction in most jurisdictions. Further, once someone does develop an attack, if they then publish or sell that attack, it becomes instantly available to anyone. The other problem here of course is the statement about 25ft. Ultimately radio is radio and it's hard to make definitive statements pertaining to range since that'd dependent on the power of the transmitter and sensitivity of the receiver, both in control off the attacker in this kind of attack. Is the insulin pump actually somehow measuring with atomic clock precision the time it takes for a message to traverse the air from the remot and if it's longer than it takes to travel 25ft, cutting off communication? Doubtful.
