Researchers have devised an attack that forces Apple’s Safari browser to divulge passwords, Gmail message content, and other secrets by exploiting a side channel vulnerability in the A- and M-series CPUs running modern iOS and macOS devices.

iLeakage, as the academic researchers have named the attack, is practical and requires minimal resources to carry out. It does, however, require extensive reverse-engineering of Apple hardware and significant expertise in exploiting a class of vulnerability known as a side channel, which leaks secrets based on clues left in electromagnetic emanations, data caches, or other manifestations of a targeted system. The side channel in this case is speculative execution, a performance enhancement feature found in modern CPUs that has formed the basis of a wide corpus of attacks in recent years. The nearly endless stream of exploit variants has left chip makers—primarily Intel and, to a lesser extent, AMD—scrambling to devise mitigations.

    Title

    can force MacOS and IOS browser_s_

    First paragraph

    forces Safari

    Of course it’s fucking Safari. Yes it is the default browser and wrapper that apps will leverage, but Safari is not plural. Be better, ars tech.

    iLeakage

    No. I’m not calling it that. Stop trying to force catchy names, researchers. Because historically, you suck at it as a profession.

      The exploit works on any browser on an iPhone or iPad…

        Because Apple are pieces of shit which force Safari to underpin any Web interaction on those devices, which wouldn’t be such a problem if mobile Safari were worth a damn.

        But you’re right and it’s a valid point. I did miss that sentence on initial read and had forgotten about that problem. Thanks for the reminder!

          It also said this hasn’t actually ever been exploited. So, looks like they’ll collect the bounty and move on. Bugs are bugs.

            Cha-ching! Good for those researchers, get that bag. It’s much better than finding out the other way.

            I’m still not calling it iLeakage though. They’ll have to make do with the well-deserved cash.

      Stop trying to force catchy names, researchers.

      From someone who works regularly with vulnerability management, it’s actually needed.

      Vulnerabilities have really boring numbers and it’s difficult for humans to discuss them in a meaningful way. I believe the first vulnerability to get a “name” was heartbleed, the theory being that with a name people would take it seriously and discuss it properly. Given the severity of this vulnerability, it probably got a name but since it’s being patched by the vendors affected, it was probably not needed.

      Heartbleed was needed because individual web sites had to update their software immediately or have their traffic intercepted.

        Yeah, I hear you, fair point. I can’t recall CVE numbers off the top of my head either.
        Heartbleed was also a great name, whereas iLeakage is… a choice.

        I’ll probably be referring to it as ‘the latest Safari security failure’, hopefully they can ensure that description stays relevant for a few weeks.
