Critical EFI Code in Millions of Macs Isn't Getting Apple's Updates (wired.com) 91

Posted by msmash from the security-woes dept.
Andy Greenberg, writing for Wired:At today's Ekoparty security conference, security firm Duo plans to present research on how it delved into the guts of tens of thousands of computers to measure the real-world state of Apple's so-called extensible firmware interface, or EFI. This is the firmware that runs before your PC's operating system boots and has the potential to corrupt practically everything else that happens on your machine. Duo found that even Macs with perfectly updated operating systems often have much older EFI code, due to either Apple's neglecting to push out EFI updates to those machines or failing to warn users when their firmware update hits a technical glitch and silently fails. For certain models of Apple laptops and desktop computers, close to a third or half of machines have EFI versions that haven't kept pace with their operating system system updates. And for many models, Apple hasn't released new firmware updates at all, leaving a subset of Apple machines vulnerable to known years-old EFI attacks that could gain deep and persistent control of a victim's machine.

Apple does claim they make inroads into enterprises, but that is mainly forced because any company that wants to create an iOS app has to have at least one Mac to compile the code on.

      Except that the people who upgrade their Macs every year or two are few and far between. Apple knows this well. That said, TFA even mentions the EFI update failed on certain percentages of NEWER systems, like the 2-16 MacBook. To wit: " And three versions of the 2016 Macbook Pro had the wrong EFI version for their operating system version in 25% to 35% of cases, suggesting they too had serious EFI update failure rates."

      This doesn't sound nefarious to me, it sounds more like there's a hiccup in the update process, which thankfully doesn't render the system a brick when it fails. Naturally something that needs to be addressed though.

      For what it's worth, I'm happily working away on a 2011 iMac, which in the past 6 years has only had one problem, a failed hard drive. This was a recent, and certainly not unexpected failure. Anecdotal for sure, but this is the case for most people I know who own a Mac as well. It's also the reason they (and I) will purchase a new one when the time is right. I know it's trendy to blindly bash on Apple though.

      • For what it's worth, my posts are made from a 2010 Mac mini, which in the past seven years had its RAM upgraded twice (from 2GB to 8GB, then to 16GB) and hard drives upgraded twice too (from 320GB to 750GB, then dropped the optical drive to add an SSD).

        I second this!

        My newest Apple Computer is a 2012 nrMacBook Pro with a spinning-rust HD (that hasn't failed yet). It looks and works exactly the same as when I bought it in May, 2013.

        Out of all of my Apple-owning friends, I don't know any that are on the "Upgrade Treadmill" that Slashtards like to constantly allude to. One did just buy a 2017 MBP, but her previous MBP was a 2009 model, and the other recent Upgrader bought himself a 2016 MBP as a retirement gift. That replaced his 2007 MBP.

      You're buying Apple for an integrated hardware/software experience. It's their responsibility for keeping their hardware firmware up to date and secure.

      Microsoft doesn't have that responsibility in the PC realm. The downside is you have to do it yourself. The upside is that's between you and your mobo vendor, and you can do it without Microsoft's involvement.

      Our research focused on the Apple Mac ecosystem as Apple is in a somewhat unique position of controlling the full stack from hardware, through firmware, OS, and all the way up to application software and can be considered widely deployed.

      There's a fundamental difference there. Very few windows machines are eco-system controlled. i.e. There's a metric shitload of firmware updates out there for motherboards but in general they just don't get applied, because it's not a process that is automatically handled by a single vendor through a single update system.

    I guess you would say this is another example of Apple simply dropping support in a way most users won't notice. I would say many PC makers also stop doing bios updates as well after a few years. Not excusing either of this but it does appear to be something not exclusive to just Mac's.

    The length of time that some system has not been updated does not alone provide a good metric as to how secure it actually is or isn't. Its certainly a mistake to judge the invulnerability of some system just by when it was last updated, which seems to be what the article is doing.

    It was Microsoft who managed to brainwash the world into thinking that weekly/monthly updates are just some normal aspect of all computer systems. prior to then, it was not unusual for updates for professional OS's (SunOS, HPUX, Solaris, VMS etc) to be more like years apart.
    A high frequency of updates is absolutely necessary if you're running a fundamentally crappily-designed OS like Windows, but let's not paint all things with the same brush.

    That said, I do agree that Apple should release updates every time a new exploit (EFI or otherwise) is identified, which the article also clearly mentions just isn't happening.

  • I'm a little unclear why a bootloader would ever even be in a position to become 'critical'. Either it works, in which case the machine works and a real operating system takes over, or it doesn't, in which case the machine displays the ultimate in security and fails to deliver service to anyone, including malicious agents.

    If bootloaders are now written to somehow be remote-hackable, we have done something very wrong.
