Article note: Always fun to see what Trammel is up to. \r\nThis week: They've PoC'd a jailbreak that unlocks all the modes on cheap Airsense CPAP machines, because the only difference between Airsense CPAP, BiPAP, BiPAP-ST, and iVAPS units is firmware lock-outs, it's all the same hardware.\r\nThe strong suggestion is you shouldn't use it until the vendor and FDA weigh in, but it's amazing how much of tech's margins are pure bullshit.<\/div>

As infections from the ongoing COVID-19 pandemic continue to climb, hospitals around the world are struggling with a potentially fatal shortage of ventilators, the bedside machines that help patients breathe when they’re unable to do so on their own. Meanwhile, hundreds of thousands of lower-grade breathing devices known as continuous positive airway pressure machines sit idle in closets or warehouses because their manufacturers say they can’t perform the same life-saving functions.<\/p>\n

Security researcher Trammell Hudson analyzed the AirSense 10<\/a>—the world’s most widely used CPAP—and made a startling discovery. Although its manufacturer says the AirSense 10 would require “significant rework to function as a ventilator<\/a>,” many ventilator functions were already built into the device firmware.<\/a><\/p>\n

Its manufacturer, ResMed, says the $700 device solely functions as a continuous positive airway pressure machine used to treat sleep apnea. It does this by funneling air into a mask. ResMed says the device can’t work as a bilevel positive airway pressure<\/a> device, which is a more advanced machine that pushes air into a mask and then pulls it back out. With no ability to work in both directions or increase the output when needed, the AirSense 10 can’t be used as the type of ventilator that could help patients who are struggling to breathe. After reverse-engineering the firmware, Hudson says the ResMed claim is simply untrue.<\/p><\/div>
