Several readers have sent in news of a presentation at the Black Hat security conference from a diabetic security researcher, Jerome Radcliffe, who is looking into the security of automated insulin pumps. While most of the headlines are sensationalist, referencing "lethal attacks from a half-mile away," Scott Hanselman breaks down the media reports and weeds out the inaccuracies, explaining that while this is a valid area of concern, diabetics don't need to cover themselves in tinfoil just yet. "Just to be clear, Jerome has not yet successfully wirelessly hacked an insulin pump. He's made initial steps to sniff wireless traffic from the pump. I realize, as I hope you do, that his abstract isn't complete. Hopefully a more complete presentation is forthcoming. I suspect he's exploiting the remote control feature of a pump. ... What Jerome has done, however, is posed a valid question and opened a door that all techie diabetics knew was open. It is however, an obvious question for any connected device. Anyone who has ever seen OnStar start a car remotely knows that there's a possibility that a bad guy could do the same thing."
