Hack Causes Pacemakers To Deliver Life-Threatening Shocks (arstechnica.com) 72

Posted by BeauHD from the patient-safety dept.
An anonymous reader quotes a report from Ars Technica: Life-saving pacemakers manufactured by Medtronic don't rely on encryption to safeguard firmware updates, a failing that makes it possible for hackers to remotely install malicious wares that threaten patients' lives, security researchers said Thursday. At the Black Hat security conference in Las Vegas, researchers Billy Rios and Jonathan Butts said they first alerted medical device maker Medtronic to the hacking vulnerabilities in January 2017. So far, they said, the proof-of-concept attacks they developed still work. The duo on Thursday demonstrated one hack that compromised a CareLink 2090 programmer, a device doctors use to control pacemakers after they're implanted in patients. Because updates for the programmer aren't delivered over an encrypted HTTPS connection and firmware isn't digitally signed, the researchers were able to force it to run malicious firmware that would be hard for most doctors to detect. From there, the researchers said, the compromised machine could cause implanted pacemakers to make life-threatening changes in therapies, such as increasing the number of shocks delivered to patients. Rios and Butts were also able to use a $200 HackRF software-defined radio to hack a Medtronic-made insulin pump and make it withhold a scheduled dose of insulin. Medtronic has released a page that lists all the security advisories they have issued on the pacemakers and insulin pumps.

    It's not a gizmo no one cares about, all the products in the 80/90s had plenty of testing before shipping with just one firmware that wasn't updateable. These updates make manufacturers lazy and sometimes they push out something worse than the one that preceded it.

    No updates, much less need for security. I don't want stuff in me to use the internet in any fashion.

    • There are a lot of good reasons to have these devices connect remotely for firmware updates. For instance, the ability to recognize arrhythmia using signal detection has improved dramatically in the last 5-10 years. For defibrillators, that can be the difference between appropriate and inappropriate shocks where the machine misreads the rhythm. Same is true with pacing and other treatments for a pacemaker. I have a device like this, so I've read a lot about these hacks. I have a device from a different man

When you go to a hospital, you may get a choice between a traditional drip, dosage measured via drip rate, and the computerised equivalent, with 85 levels of menus, some with hundreds of entries, a 640 x 480 display filled with the programmers showing off how much crap they can cram into a 640 x 480 display, dozens of options and parameters to get wrong, beeps and bongs all night long, graphics and animations and a hidden flight simulator and a Tetris game as an

    In addition to using signed binaries, run a pair of wires to just beneath my skin.

    If it ever needs reprogramming, make a small incision and wire me up for the upgrade.

    Save the wireless things for less-consequencial things like reading the device's status. Even then, figure our some way to prevent an adversary from reading it unless he is rught up next to me for an extended period of time.

    Sure, you can hack a pacemaker and kill its wearer. You can also shoot him with a gun, poison him, bomb him, whatever. It is made even easier by the fact that people who wear pacemakers aren't usually at the peak of their shape.

    But like they say in obligatory xkcd [xkcd.com], most people aren't murderers.

    • You are right.

      Somebody is going to hack into the programming device in some doctor's office. Wait for the device to get turned on to update it's firmware, perform a man in the middle attack to load the firmware of the hacker's choice, which is designed to change the parameters of a specific pacemaker device in ways which will kill the patient, not right away, but later, say when the target is asleep.

      I'm thinking that if death of a target is your goal, there might be easier ways..

        You are right that this is useless if simple death of a target is your goal.

        OTOH, if you want to commit murder in a way that is hard to trace back to you, short of having a Death Note, this might be the next "best" thing.

      Most people aren’t swatters, either - but unfortunately a few think it’s funny. And those sorts of people seemed to be wired not to blame themselves when their “prank” goes very wrong [kansas.com].

      Here's why this line of reasoning fails:

      All it takes is one individual who will threaten to kill pacemaker users unless they get ONE MILLION DOLLARS *raises pinky to mouth*

      Is the threat real? Who knows? Probably just some guy in Romania making idle threats. Can a major company risk it?

Do you : 1) do make a plain sniper murder or do you 2) hack the re-programmer for the pace maker so that if it detects a specific patient it change the therapy to be deadly ,e.g. fail to deliver shock or do it at an irregular rate, but report to forensic the correct rate ?
