Defcon already delivered by exposing California’s FasTrak toll system for the security hole that it is, but that’s not nearly all that’s emerging from the Las Vegas exploitation conference. For starters, a plethora of medical device security researchers have purportedly figured out a way to wirelessly control pacemakers, theoretically allowing those with the proper equipment to “induce the test mode, drain the device battery and turn off therapies.” Of course, it’s not (quite) as simple as just buzzing a remote and putting someone six feet under, but it’s a threat worth paying attention to. In related news, a trio of MIT students who were scheduled to give a speech on how to hack CharlieCards to get free rides on Boston’s T subway were stifled by a temporary restraining order that the university snagged just before the expo. Don’t lie, you’re intrigued — hit up the links below for all the nitty-gritty.

Around 1.5 years ago, we got wind of researchers in the UK working up a battery-free pacemaker. Fast forward to now, and we’ve got yet another breakthrough in the field. Purportedly, a crew of Osaka University scientists have created the “world’s first optical pacemaker,” and in an article published in Optics Express, the team details how “powerful, but very short, laser pulses can help control the beating of heart muscle cells.” In theory, this discovery provides the means for dictating said cells within a controlled setting, which could help researchers “better understand the mechanism of heart muscle contraction.” As amazing as we’re sure this is to the science world, throwing “lasers” and “heart” into the same sentence just doesn’t elicit warm / fuzzy feelings.

While it should hardly come as a surprise given the near constant stream of hacking fears we hear about these days, researchers are now warning about a possible vulnerability to an especially important bit of technology: medical devices that control the human heart. As The Wall Street Journal reports, the concerns are mostly centered around so-called “programmers,” which are devices used to wirelessly communicate with the implanted defibrillator or pacemaker. Those devices are obviously only sold directly to physicians by a select group of companies but, as the researchers warn, it is at least conceivable that hackers could transmit the same radio signals using another device, allowing them to shut down the defibrillator or deliver a shock, or possibly even obtain a patient’s medical information. The researchers are quick to point out, however, that this is “theoretical risk, not an actual risk,” and they’re not recommending that anyone consider deferring an implantation or removing a defibrillator.

It turns out that 17-year-olds probably aren’t that good at studying electrical interference — and its effect on pacemakers — created by iPods. Unlike the data presented to the Heart Rhythm Society last year by a high-school student, which demonstrated the music player’s ability to interfere with heart-regulating devices, the FDA now says that the gadgets are completely safe for use. Researchers measured magnetic fields produced by four different models of Apple’s ubiquitous device, and found no reason why your grandmother can’t keep jamming to her South of Heaven reissue. Said FDA researcher Howard Bassen, “Based on the observations of our in-vitro study we conclude that no interference effects can occur in pacemakers exposed to the iPods we tested.” We hope the FDA will follow this up with a definitive study on the effects of boomboxes on hip implants.
