Medtronic Pacemaker to Slash Heart Risks


Traditional practices must give way to the modern and the innovative. Medtronic Incorporated’s EnRhythm pacemaker has made the art of living easier for many former cardiac patients. The deaths,...

FDA, ICS-CERT issue warnings for medical device, hospital network security

Reports that medical devices implanted in patients or used for their treatment may have dangerous vulnerabilities are not new, but a new "safety communication" is focusing more attention on the issue. Ars Technica points out that the Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) group that works along with private industry to protect the nation's infrastructure issued its own alert alongside the FDA's, focusing on the many embedded devices that are protected only by hard-coded passwords.

The ICS-CERT message recommends restricting physical access to sensitive hardware, improved designs that are more resistant to potential attacks and increased network security. The FDA lists various vulnerabilities it's become aware of like network connected devices being infected by malware, mobile devices being targeted to access patient data, the previously mentioned hard-coded passwords issue and more. Going forward, the FDA is collecting reports of "adverse events" to determine if security has been compromised, and will issue new guidelines on mobile health technology later this year. We've seen examples of potential security solutions for pacemakers in the past, and the more connected healthcare devices become we're sure patients expect any potential vulnerabilities to be addressed as well.

Hacked Pacemaker Transmitters Could Turn Pacemakers to Literal Heartstoppers

Pacemakers save millions of lives, but a security researcher has shown that they can be used to kill on a massive scale as well. Speaking at the Breakpoint security conference, Barnaby Jack of IO Active reverse engineered a pacemaker transmitter – a device like this one used to monitor installed pacemakers – eventually enabling him to wirelessly deliver 830v shocks to a pacemaker using his laptop. Yikes.

Even worse, Jack warned that a hacked transmitter could control all pacemakers within 30ft. Aside from jolting people, the compromised device could also be used to read and write patient data or load infected firmware into a pacemaker. These infected firmware could even be made to jump and infect other pacemakers, extending a malicious attackers’ range and possibly resulting to mass murder. Jack says he demonstrated this flaw in order to warn pacemaker manufacturers to step up the security of their device. Let’s hope they do.

Fake jellyfish made from rat cells have a place in our hearts (video)

Fake jellyfish made from rat cells have a place in our hearts (video)

There's a whole sea of jellyfish out there ready to sting indiscriminately. So, why do we keep trying to make them? Scientists from Harvard and Caltech have a pretty good reason for creating fake jellies -- they hope to mend broken hearts by adapting their 'pumping' style of movement. Much like our own vital organ, the creatures are a mass of muscle adept at shifting fluid, meaning the research has several medical applications, such as bioengineered pacemakers for busted tickers. In creating the Medusoids, the team used a silicon scaffold coated in functional rat cardiac tissue, copying the muscle layout of a real jellyfish as best they could. When immersed in salt water and treated to bursts of current, the cells contract and cause the silicon sheet to move in a way eerily similar to the real thing. Next step for the team? An autonomous version that can move and potentially feed without their influence, of course. And, after seeing the little swimmers in action, we've certainly got palpitations. See what we mean after the break.

PSA: Pacemaker DJ app for BlackBerry PlayBook drops into the mix today

Pacemaker DJ app for BlackBerry PlayBook drops into the mix today

What started as hardware, back in 2008, has since been superseded by advances tablet-tech. Logical then that the team behind Pacemaker has remixed the idea for 2012. We've already had a sneaky peek at the PlayBook app, but that was back in beta-land. Today, it launches proper. The official unveiling will be at Barcelona's Sonar festival, but if you didn't get a ticket (or even if you did) you can get your hands on it today from BlackBerry App World for $19. A little more than Cut the Rope, sure, but small change compared to the original hardware's $850 price tag.
