back to article BlackBerry claims it can do to ransomware what Apple did to its phones

While ransomware continues to extort factories, hospitals, schools, businesses, and ordinary netizens, BlackBerry reckons it can quickly rescue peeps from malware infections. The Canadian biz's days as the smartphone king long gone, with Apple making quick work of its hardware. And although it still licenses its name to a few …

      Haven't Sophos been doing this for a while so not first to market.

      I can't see how RIM haven't worked out the Blackberry brand has a little image issue with some tech folk.

    Sounds a bit like Volume Shadow Copies, or zfs snapshots. I presume there is something similar on Linux.

      Nah, any decent ransomware wipes shadow copies before encrypting.

        Only if it is run with an account that has sufficient privileges.

        Who lets end users have admin rights these days? (Actually, plenty, sadly...)

        Or doesn't remind users not to store their data on a network/cloud file server (where they definitely shouldn't have admin rights)?

        Standard users can't remove VSS snapshots.

      NILFS2

      It could also be NILFS2 snapshots. NILFS2 implements an approach where each file system change (checkpoint) can be (but does not have to be) treated as a snapshot, which allows a very fine-grained approach. If you combine this with sufficient LVM snapshots*, you would be able to roll back any file to any point in its history.

      *Take an LVM snapshot before the NILFS2 circular buffer overwrites itself, back it up, then repeat as necessary ad infinitum.

    Meh

    We can already do this (on desktops/servers)

    We can already do this (and I do) with versioned auto-backup. If anything happens I can roll back to 2:30 PM yesterday (or 1:49, or whenever) with a safe boot or boot disk. Of course if BB can actually make an all devices suite that's reliable, has almost no impact on running systems, and reliably easily restores - sure, why not?

    Odds are it'll be bloaty, fragile, overpriced Enterprisey crap, but I'm open to looking.

      Crap

      Rather like UEM then?

      Been hoping that'll start working properly for two years now but new bugs keep on appearing. Current one is not being able to activate Android 7.1 devices. Oh, and another one is not being able to get app updates on some phones.

      Plus it's Windows server software but for some reason they wrote it in Java, so it needs crazy amounts of RAM and is extra slow.

      The features sound great on paper, and if they worked (as described, all of the time) it would be fine.

      Very seriously considering ditching it.

    BB trying to stay relevant through scare tactics and trying to solve a problem that should not exist. If your system has been compromised that would warrant use of such software from BB, then you were not doing enough to prevent compromise or performing adequate backups.

      You're missing the point. It's part of BlackBerry's enterprise management tools. So if you are already using that (and plenty of people are) then this is a handy addition.

      Put it another way. Does a mere backup system also manage mobile devices of all sorts, control access to information, and everything else that a decent enterprise management tool does? No.

    Sounds a bit like file versioning, something tried in various older file systems but noted to have overhead issues. It would have to be root-proof, though, or a privilege-escalating malware will simply find a way to wipe the versions as well.
