I'm not sure if this is real, but if it is: this week is unbelievable. I really hope it's not the new normal, but unfortunately I don't believe this myself.

It's a minuscule part of the new normal.

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.

Insecure webpages, broken certificates and an insecure PDF library... You shouldn't have anything more connected than an FM radio at this point. Security is no longer something a private individual can deal with.

They can still hack your mind with ads.

There's every incentive for nation states and other espionage outfits to keep these types of exploits under wraps. This has probably been the new normal for some time ..

I for one have experienced multiple lifetimes worth of internet madness and will be looking to airgap / disconnect as many devices as I can get away with.

People have been paying a premium to companies like Apple for a reason. You've got nothing to worry about.

Decade of people's purchases has been invested into safety and security. It's absolutely unthinkable that a $7t market cap company with an army of 200k workers will ever leave people high and dry. They proudly went public, so we know they have the public's interests at heart.

God I hope this is sarcasm.

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.
mrweasel 16 hours ago||
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.

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. Apple, of course, wants you to buy two devices. I do have UTM with Jit Linux running on my iPad, via altstore and entitlements and so on, but it is all a bit complex and still fairly slow.

would this let you use the usb port to host serial devices? Swooning pretty hard at the idea of this. <3

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 17 hours 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.

You say this, but have you tried an old iPhone recently? I did, and it was actually pretty terrible. The quick little swipes to switch between apps is so much more natural now.

Perhaps if you know how. Watching my dad use his iPhone.. Every time have to teach him something new, and hope he remembers it.

So stupid interface. No discoverability.

I recently learned you can swipe on the address bar in Android-Chrome to navigate to the next/previous tab. Also, press+hold on the tab count button to show the tab's options e.g. close tab. Now my address bar is on the bottom of the screen.

Terrible discoverability. I guess the genalpha kids know gestures like this, but stuff like this makes me feel like a boomer.

pmontra 7 hours ago|||
Android Firefox had that swipe gesture for a long time. You tap the tabs count to show all tabs. You can close any of them from there. A long tap opens a menu. New tab, new private tab, close tab.
nomel 11 hours ago|||
Safari added this in iOS recently. You can also swipe up on the address bar (after tapping it to make it "big") to swipe between pages, similar to the home screen. Found it on accident.

Try going back to thumb typing, no long press symbols , and no cursor movement from your spacebar. I've almost thrown my test iPhone at work across a room more times than I'd like to admit (since it doesn't belong to me)...

I wish. The iPhone 5S is the last one I can reliably type on. Idk what they did to screw up the hitboxes.

Yes, my wife has an iPhone 6, I wish I had that. Though half of that is the jack.

They are going to run out of vulns eventually when the code is rewritten in memory safe lang & the rest are found.

> They are going to run out of vulns eventually when the code is rewritten in a memory safe lang

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.

edit#2: This is all assuming we don't get true AGI. I hope my assumption is right

He's right though. We'll run out of vulnerabilities eventually.
alt227 15 hours ago||
Im pretty sure more vulnerabilities are being created in new code all the time.
KingMachiavelli 12 hours ago||
Crazy, you would think Apple would have already done AI-assisted vulnerability scans using the latest and most expensive models.

Absolutely crazy how PDF parsing and image rendering are still exploitable.

eyalitki 13 hours ago||
Aside from bragging how cool they are, what value is there for demonstrating a yet-to-be-patched vulnerability? I don't understand why old-guard infosec stars from Calif can do as they want, responsible disclosure be damned.

Just as a reminder for some folks here: During their WeWorm research in July–September 2026, Calif didn't stop at proving RCE to Tencent—they spent an extra week using AI to build a fully functional, self-propagating zero-click worm across three live phones, triggering temporary account bans from Tencent during testing.

I don't see this as irresponsible disclosure. They show that the vulns exist, but don't give any other details (unlike previous Calif releases). Not even a hint at what the exploit chain is like other than that it starts with a PDF, which is a surprise to no one.

They're of course also doing it for internet kudos, but attracting attention like this will help encourage people to update. Thanks to this article, I'm going to apply the next iOS security update ASAP, and tell everyone I know to do this the same. (hopefully it comes out soon)

I do wish they clearly stated the vulns have had been reported to Apple and when.

We disclosed most of the bugs used in these chains to Apple, and are going to disclose the rest, if not already.

Not sure what exactly your point is. The WeWorm demo was done in a controlled environment.

Also we do this for free. We don't charge neither Tencent nor Apple. We don't even take their bounties. Why can't we have some fun?

If you're so upset about how we do it, my suggestion is go find your own bugs.

eyalitki 2 hours ago|||
You literally just said your company released an exploit demo before disclosing some of these vulnerabilities to the vendor.

As for your suggestion, I was an infosec researcher, I worked for 3 years with vendors to help them patch before I can even tweet anything about my research. I even flew to their HQ to assist in patching when needed. After Covid I transitioned to a development role, and now I'm on the other end, handling security reports from researchers.

Based on this dual point of view, let me tell you that for a security engineer in Apple that will learn from your video about vuln your company did not even disclose yet, this karma harvesting is as far from "coordinated disclosure" as possible. Their managers will be fuming, and the stress they will be in given the media frenzy will be off the charts.

Is it irresponsible? They've revealed barely anything about how it works, besides that the first step is a PDF, and something about Glyph Grift.
eyalitki 12 hours ago||
What is the value of revealing anything at this time point, when no patch is out? What use is it for the public?

Just last Black hat there was a "glimpse disclosure" that was later followed with proper fixes and details. I gave my AI agent the details that were supposed to be "useless", before the patch was out, and it found the vulnerability in less than an hour.

We shouldn't even enter this game. And with the track record of this specific group, I didn't exactly get the impression that their incentive is to help fix things, but rather to promote their brand while others be damned.
