    It’s a pity we gave in to the “ecosystem” play by these huge companies.. even if I jailbreak my iOS and never let it update.. Apple can easily detect the jailbreak and lock me out of anything iCloud, and iMessage and such. iPhone would be one glorious iPod touch after that.. :-(

    Seeing all these gives me the same energy of early days of jailbroken Android phones where one could become root and do whatever with the hardware… I stopped considering such tinkering because I got tired of finding those little tweaks and fixes on forums like xda every time something was updated. With the LLMs capable of automating that tool, I might find those old school way of mobile phones again…

      Vote with your wallet. Fuck them.

      You shouldn’t have to use LLMs to run your software.

      Give it another 6-12 months until the big AI shops shut those capabilities down and running local ones becomes cost prohibitive.

        Apple is too big for that. Hard regulation is the only way out right now. Maybe breaking them up too.

          No it's not. You can vote with your wallet right now. Nothing is stopping you.

            What if I want to vote against both Apple and Google but still be able to do my banking business?
          • ctoth 7 minutes ago
            I'm blind. Apple has explicitly said they wouldn't consider the "bloody ROI" of accessibility (will fund it no matter what). This is important to me. Software freedom is also important to me. What am I to do?
            • well_ackshually 2 minutes ago
              You grab an Android phone anyways because Android accessibility is very much on par or even better than whatever slop Apple is putting out with VoiceOver these days, and developers also somewhat care about it more on Android.

              You're also going to benefit from European mandates to have accessible mobile apps anyways, it's coming for free to you.

          • saghm 11 minutes ago
            Yes, I can vote with my wallet, but no, it doesn't make a difference. I've been voting with my wallet since day 1 by never buying an iPhone because of how closed it is, and unsurprisingly, this has done absolutely nothing to change how open the iPhone is.
            • righthand 1 minute ago
              If you did that then you probably made clear your reasons which probably created mindshare with others which probably has helped the EU open up the iPhone. Don’t be so defeatist because the outcome isn’t immediately apparent.
          • afavour 21 minutes ago
            But the alternative is another monopolistic tech giant. There is no viable third platform. So I agree with OP, the answer is breaking them up.

              There is no "viable third platform" because people don't vote against the two existing ones with their wallets.

              Can you name an example where a government succeeded in breaking up a monopoly, and the result was better for consumers? AT&T, IBM, and Microsoft were all "broken up", but it didn't make a difference for consumers. In every case, a competitor forced them to change their ways.

            Many things are stopping you. I see this response all the time as a counter to inappropriate behavior by monopolistic giant entities.

            It's the wrong way of thinking about the problem. The whole point is that they've gained too much market power for any individual to be able to stop them meaningfully, and that collective action using the power of government is the only way.

            Any argument that tries to talk people out of that is on the same side as the tech oligarchs, in my opinion.

        The loss of your purchase is insignificant compared to the money Apple and Google make from their walled gardens.

        Plus what other viable options are there in this duopoly?

        Apparently there’s a popular 3rd option in Asia but is there any support for western apps? And how are you going to convince a million other people to switch?

        I don't expect that to happen, but I do expect Apple et al to spend trillions of tokens hardening their platforms against users and red-teaming to find these sorts of holes before release.

      • neya 8 minutes ago
        > Vote with your wallet. Fuck them.

        Easier said than done. Because, "Apple can do no wrong" is the general public perception. Look at any wrongdoing by Apple - whether they were caught slowing down the phones, degrading cameras on purpose or even the lawsuit where they were caught spying on people's voice recordings. There will always be some NPC defending them as if the billion dollar corporation gives a shit about them.

        That or "Apple is the only pro-privacy company in the world" despite there being an active lawsuit against them for the exact opposite.

        So, I say: Vote with your wallet. Fuck them...and the fanboys.

        How are running local ones going to become cost prohibitive? Indications are that Nvidia has been channel stuffing (artificially inflating perceived demand), which suggests massive oversupply of GPUs.

    • tsunamifury 38 minutes ago
      We gave in because open source and hobbiests do not design good products and even worse shared systems, as much as they enjoy self-righteously declaring their values. And shared systems require trust, planning, and goal setting in a way no open system would ever build.

      1) They of course lack the resources

      2) Often lack professional displince across all skills required

      3) Mostly make for themslves or whats interesting, not whats needed.

      4) The release schedule is laughable at best.

      > even if I jailbreak my iOS and never let it update.

      Two things:

      a) Why the would you never want to update an OS in this day and age ?

      b) I understand the perspective of people insisting on wanting to be able to root their phone. But how about we take a step back and look at the reality of the 2026 security environment ? An environment where you have:

           - Increasing volumes of increasingly sneaky security exploits on one side
           - A phone with your 2FA apps, your banking apps, your email apps, your kids photos on the other
      
      Frankly. I want Apple to lock down my iPhone as much as possible in that context.

      If I want to be root, I can do so on my desktop or a cloud VM or whatever.

      But making root on a phone easy just seems like a recipe for disaster... if its easy for you, its easy for the bad guys too.

      • mort96 35 minutes ago
        > a) Why the would you never want to update an OS in this day and age ?

        Because updates break the jailbreak. If Apple actually had a sanctioned way to let you do what you want with the device you bought there would indeed be very little reason to not update.

        • mahboi 30 minutes ago
          Updates slow down your phone, eg Liquid Ass. Lots of people follow the rule of only running the OS that came with your iPhone.

          > Maybe your phone doesn't have banking and stuff on it

          I don't know where you live, but where I am most banks insist on proprietary 2FA via their own app. Only (some of) the fintechs allow TOTP.

          Yes you can get your codes via SMS, but I thnk we all know what a security mess SMS is. I would rather have the bank's proprietary app since at least everything will be going over HTTPS and also eliminates most of the vulnerabilities associated with SMS just by virtue of being an app.

          • tadfisher 15 minutes ago
            Passkeys are the standardized version of the bank's proprietary app. Well, except for the device attestation part, that won't happen on iPhones.

              My iPhone passcode was either unset or 2222 until like 2018. At times it was jailbroken af. It had messaging and stuff. I'm not one of those people who uses a phone to do tons of sensitive things like payments for some reason, I have a credit card. Wouldn't have been the end of the world if someone hacked it, and nobody did.
    • tw600040 31 minutes ago
      You do understand the reasons right? iCloud, iMessages etc are an interplay of software in your device, software in cloud and some networking. They have to work together. A jailbroken phone can have a tinkered iMessage app. Supporting tinkered / unsupported versions is more overhead / possible security risk. Why would you expect them to take on that?
      • jd3 24 minutes ago
        I agree with your point, though I can easily modify ~/Library/Messages/Attachments or ~/Library/Containers/com.apple.MobileSMS/Data on macOS, which is a platform similarly secure to an iPhone when you take sandboxing, sip, etc. into account. So Apple already supports macOS, which can be tinkered, no? I guess the argument is that by locking down iOS, a platform which was never open, they just never needed to handle that class of security risks which are introduced when customers have more freedom.

        I did actually discover a bug in iOS (related to photos which have failed to sync to icloud for the past four years) by investigating why there were over 23k empty folders in ~/Library/Containers/com.apple.photos.ImageConversionService/Data/tmp/, fwiw.

        • runjake 20 minutes ago
          You're right, but I could see Apple acting on iOS alone, just because of scale.

          There are some orders of magnitude more iOS/iPadOS devices than macOS devices.

          There's a bunch of ways we could debate ourselves about things Apple would or wouldn't do, but at the end of the day, Apple is going to do whatever is in it's best interest.

      • sersi 18 minutes ago
        My computer is jailbroken, I have sip disabled yet icloud and imessage work. So what makes my computer different from my phone?
      • tarpitt 14 minutes ago
        Who bears the security risk? The user.

        The only security risk for apple is a job security risk if the ecosystem lock-in is eroded.

  • jeroenhd 28 minutes ago
    Very cool demos, but now I'm interested to know: does enabling Lockdown mode help at all against these exploits? It'll theoretically protect against a lot of common attack vectors, but I'm curious about its real-life effectiveness.

      My favourite part from the first video is how much effort it took to drag up from the bottom of the screen to get back to the home-screen. This reflects my experience with how iOS handles touch gestures in general.. also super easy to accidentally activate "Reachability" mode!
      • ezfe 1 hour ago
        The reason they're having trouble is because they're in the simulator.

        Also, if reachability bothers you like it does me, you can disable it.

      Too huge attack surface. Good candidate for victim trust (who would not open a pdf file on an iPhone?).

      So pdf and images are the best vector for iPhones.

      Once you escape the parser you have to reach and escape the sandbox and from there reach the kernel.

    • aseipp 58 minutes ago
      Subverting the secure boot/upgrade chain would require a SecureROM exploit and presumably a compromise of the Secure Enclave, so the answer is almost certainly "no" (even prior major exploits from recent memory like usbliter8 are tethered and don't exploit the enclave; the last true untethered Jailbreak was iOS 9 or something.) An upgrade would fix it. The internet reporting claims this break they are showing in this video is untethered though, which is extremely rare on its own.
    • drum55 1 hour ago
      The videos sort of imply that these are userland rather than bootrom, whatever payload they have running is getting hit before first unlock, which isn't a lot of surface. They specifically say to not update which pretty much confirms where the attack surface is. Somewhere after the kernel starts but before the main user space is unlocked with the passcode.
    • easytiger 45 minutes ago
      Well the governments and supranational bodies who want to read your messages would be aghast at you having root on your phone.

  • ghm2180 1 hour ago
    Noob q: Does this(and most) hacks like this on the iphone likely rely on some kernel module — or what it talks to for executing code — being compromised to run arbitrary code execution? I dunno about ios but it seems from the videos that something that reads imessage attachments was compromised for privilege escalation.

    Like what im mean is an attack vector shaped similar to https://pepsipu.com/blog/2026-10-switch2-jailbreak-ns2jb/ i.e. they compromised `fs` module that did not protect against a buffer attack(in memmov)? My understanding is that most core kernel modules are difficult to attack directly because of XOM, PAC and CFI like protections make it impossible for anyone/thing, so most likely only indirect attacks like above can work in such situations — there is a lot of incentive for teams like apple to do everything possible to improve security so i assume only these kind of difficult to find vectors remain.

  • paxy 1 hour ago
    Man, sucks to see these "hacked" iPhones doing so many cooler things than my Apple-approved one.
    • vessenes 1 minute ago
      It’s a mix - for years I wanted root on my iPhones, just like you got on android. In practice, once I had it…? I never did much beyond installing Cydia.

      With today’s hardware I might have a different take - the 18 has more than enough hardware to be a laptop so maybe I’d use it for a docking mode. But my gut is I’d probably still want a laptop even then.

      To me the upshot is : billions of development, software and hardware, have gone into the platforms - it’s hard to quickly make them significantly better.

    • Zak 1 hour ago

            Who is saying this part?

            Asking for an open device does not mean supporting malicious hacking of others. This is the single biggest false equivalence used by Apple and the rest of the industry to keep a closed ecosystem and restrict users' control over stuff they paid for. And people continue perpetuating it for some reason.

              Nobody said exactly that, but your first comment pointed out how cool the capability is without acknowledging that it is trivial to exploit maliciously.

          I'm glad to confirm your suspicion. I like to have both a walled-garden phone and several open-platform computers. They do two completely different things for me.

          To be honest, I'd like my open computers to be even more open and hackable, with a secure boot path that doesn't involve any mysterious unpatchable embedded firmware or auxiliary CPUs, but we are slowly getting there with RISC V.

          • Waterluvian 1 hour ago
            I want the same kind of phone. But I reject the premise that it's impossible to have a deeply nested "De-wall this device yes I know what I am doing yes I confirm I'm about to really open myself to issues if I don't understand the implications" settings option without compromising the walled mode security.
          • gambiting 57 minutes ago
            The point is that no one forces you to jailbreak your iPhone. If you like the walled garden - great! Keep using it! But I've been in plenty of discussions where iPhone users are literally against jailbreaks at all and in any form.

              I want a device I can give the elderly in my family that they cannot be easily induced into doing insecure things on. If there were an unlockable iPhone and a locked iPhone I want to give them the latter. It’s not enough for me to tell them not to scroll to General and click seven times on About to activate developer mode. I would prefer to just give them a device that can’t do that.

              My own parents are still relatively young and my in-laws are sceptical enough of other people that it’s currently safe but it won’t be so forever.

        • cosmic_cheese 59 minutes ago
          Having control over one's device and allowing anything and everything to have free reign on said device are two different things.

          I'd love to have more control and customizability that the user can initiate, but random executables shouldn't be able to so much as sneeze without my permission. Third party software (yes, even the FLOSS variety due to issues such as supply chain compromises) must be treated as adversarial by default, anything less is foolishness.

        • bunderbunder 1 hour ago
          Earlier today on the thread about the google play store apocalypse I posted a comment saying that I like some things about life in Apple's walled garden. But I still upvoted the parent comment because it's true and it's funny.

          Also I'd happily jailbreak my iPhone and put an alternative OS on it to extend its lifespan. I'm a living human with nuanced opinions and I'm allowed to like more than one thing.

          But to jailbreak you need to stay on an older iOS version (because Apple patches the bugs enabling the jailbreaks). And that means you don't get security updates.

        • 2III7 57 minutes ago
          I converted to an iphone 13 mini (from the S24 Ultra) after being on Android since the release of the HTC Desire in 2010. I used to install custom roms and tweak everything on all of my Android phones which actually lead me to the iphone because I realized I wanted a phone without all the OE clutter and Google crap. The only clutter on the iphone is icloud which stays out of the way and doesn't annoy me with subscription messages. Also I don't have time to fuck around with modifying my phone. I just want everything to work without user intervention.

    Is it an exploit around the library that handles PDF parsing/opening? Can someone explain how files / attachement are open on a mobile device ( android/iPhone).

    I don't understand how in 2026 this is still a thing, we have many safe languages to parse/deserialize data. Why is it complicated?

    • drum55 1 hour ago
      PDFs are basically executables, that's why it's hard. They support running code, they support decoding images which themselves have their own custom compressors that are basically code. Anything to do with image formats is rife for bad decoders, insane compression algorithms from the 90s, and a PDF is basically 1000 formats inside many different container types with executable code plastered on everywhere. If you want to make a compatible PDF viewer you'll need to be able to implement an image decoder algorithm for a fax machine that was specific to Japan in the late 80s, which was somehow ratified into a standard and is used today by all the top legal firms, or something absurd like that. When you open a PDF on your computer, depending on how it is being parsed, it can even make outbound network connections without you knowing. To safely open a PDF you need one of those bomb proof suits, a disposable laptop, and even then you might be going home without eyebrows.
      • layer8 1 hour ago
        > PDFs are executables, that's why it's hard.

        That isn’t really true, it’s not hard for PDF viewers to block by default (or just not implement) the problematic features, which also aren’t critical for the vast majority of PDF files.

        The exploitable bugs are typically the usual, some buffer overflow in an underlying image or font library or similar, but unrelated to PDFs being “executable”.

        • pishpash 37 minutes ago
          What a sleight of hand. PDF's are obviously not executable, any more than text files are. Decoders are executable and they can choose to unsafely handle input. Even plain text editors can have exploits. It's no different than any piece of complex software.
          • layer8 28 minutes ago
            The characterization of the PDF format specifically being “basically code” in any substantial manner is simply incorrect. The only PDF-specific features that reasonably meet that description is the PostScript support, which has fallen out of use decades ago and was completely removed in PDF 2.0, and the JavaScript support, which is optional, prohibited in PDF/A, and can easily be limited or omitted by a PDF viewer.
      • paxy 1 hour ago

          PDFs are just absurdly complicated in general. Dumbing down the parser might be the right idea. I wonder what consequences that would have with how intertwined PostScript and PDF in general are with macOS/iOS; maybe that's why the PostScript engine was removed with macOS Sonoma/iOS 17? I don't know if that was only user facing behavior and Apple is still working to remove the internal usages.
        • wildzzz 28 minutes ago
          That's kind of what Adobe does with downloaded PDFs, you have to click the Enable button to turn on more document features. My schematic capture app will output a PDF that has links that will take you to specific spots on a page and also some JavaScript where you can right click on a part and see it's BOM information. None of that stuff works until you click the Enable button. I've also seen some vendors offer not only normal 3D model files and 2D drawings but a PDF that has an interactive 3D model inside. It's kinda cool how much random shit can go into a PDF but it's clearly a massive malware vector.

          One neat thing I've seen is a PDF that will ping an IP catcher when opened in Adobe, regardless of the security level. The same can be done with word docs, excel spreadsheets, and even SVGs.

        • kccqzy 39 minutes ago
          No. Very few PDF exploits come from the officially sanctioned way of running code (JavaScript) inside PDF. Most are just plain old parser bugs.

              Would require defining what features are needed. "Require PDF/A" is probably a reasonable approximation, though it would break most PDFs
          • Melatonic 54 minutes ago
            I think he just means disable any of the "advanced" features mentioned above like accessing web content, running custom scripts, etc etc. You might still be vulnerable to any dependencies they use for image rendering itself but I bet it would make it drastically more safe.

            Then just have a button for turning those on as needed on a case by case basis

            • Vaushite 45 minutes ago
              If you disable features then people will see important documents as white rectangles and complain and you'll get a reputation as not working.

        > PDFs are executables, that's why it's hard. They support running code

        I don't think Apple's PDF renderer supports e.g. running JS, you'd need real Acrobat for that. Or are you talking about something else?

        > they support decoding images which themselves have their own custom compressors that are also basically code themselves.

        But this is fundamentally true for anything that displays images, right? Or are the PDF formats particularly bad for some reason?

        • wildzzz 20 minutes ago
          Yeah a lot of those fancy PDF features are Adobe-only. It's not that other apps can't support those features, it's that no one in their right mind wants to spend endless amounts of money and time trying to sandbox it.

          Most people have some understanding that shady websites can give you malware, a drive-by exploit is pretty rare but it's good that most people think just visiting a site could infect your computer. But a PDF is just a document, right? Just thinking that a PDF is just words on a page is exactly why it's such an insidious threat. Or they'll get a PDF as an email attachment, see that it's not an exe or something weird, and open it because they think a document is safe.

      • cosmic_cheese 1 hour ago
        From the standpoint of a layman it looks like there's a lot of overlap between writing safe web browsers/engines and writing safe PDF readers/engines. There just hasn't been anywhere near as much of an impetus to push PDF readers/engines in that direction because most of us aren't interacting with PDFs nearly as often as we interact with the web (and things built on web tech).
        • Melatonic 53 minutes ago

    A reminder for people who don't follow this, Calif is Thai Duong's firm. Thai discovered the BEAST and CRIME TLS attacks (with Juliano Rizzo), and then worked at Google for a bunch of years, including on Wycheproof with Daniel Bleichenbacher. The team at Calif includes lcamtuf, Dion Blazakis, Tavis Ormandy, and Stefan Esser (among many others).

    They're basically the most interesting team working in vulnerability research right now; a cross product of ludicrous talent and full-tilt AI work.

    Just before I left Fly.io a few months ago, we retained Calif for an annual pentest (we'd previously worked with Tetrel, Atredis, Doyen, and I think Include?). They were spooky good. Everybody we'd worked with was good, but Calif's results were unusually high-impact.

    I love these people and everything they're doing.

    It would make me so happy if this would allow running UTM.app with Hypervisor support on iPadOS. I don't want to travel with two devices, the would be enough, but sometimes I need a real desktop.

      that's just not how it works at all though is it. Good luck writing the kernel, firmware etc in a completely memory-safe way. And even if that was accomplished, memory safety isn't the only class of vulnerabilities, it's just the most common.

      > and the rest are found

      If they kept a stable version with no updates or new features *ever*, only security patches, for decades, then maybe that could be possible, yeah. But Apple users aren't exactly the kind of people who would enjoy such stability and security anyways, it comes with the compromise of novelty. Stability and security aren't very fashionable either.

      edit: Obviously a "memory-safe way" means no `unsafe` blocks in Rust, too.

      If this continues I'll argue that you have to be absolutely insane to allow network connected electronics into your home in the future. This is Apple, known for locking down their device to the extreme, and yes some people would love to use this for jailbreaking their phones, other organisations want to root your phone for .... other purposes.

      I think in time (a few years) the gap will close a bit. As AI is used to harden software, it will be harder to break. Software not validated by AI will continue to be vulnerable to it.

        So what happens if AI becomes something that you need to actually pay real money for? Then only Apple, Google and Microsoft can affort to do network exposed software. Smaller companies and solo developers are just f-ed if the price of running LLMs goes up as investor money dries up.

      A couple of PDF exploits from iMessage and Signal leading to code execution, and an app that roots the phone. Also, they seem to have managed to make their malware survive a reboot, which is difficult. That's another reason why automatic reboots are considered a security feature: exploits leaving malware in-memory are a lot easier to build than malware that survives a full reboot, passing all stages of signature checks and validation.

    Someone correct me please if I’m wrong but is this because iOS doesn’t sandbox their processes? I think I read Safari in particular doesn’t, but wonder if this is system-wide issue.

    Also wonder why they choose to publish and not cash-in the Apple bounty..

    • odo1242 29 minutes ago
      iOS does sandbox their processes really well, that's why this hack was as difficult as it was. The Safari thing you're talking about is JIT - iOS disables all runtime code generation across the system except in Safari (for JavaScript), but this is a completely separate thing from sandboxing.
