A 0-click exploit chain for the Pixel 10

 https://projectzero.google/2026/05/pixel-10-exploit.html

by happyhardcore

5/15/2026 at 4:38:13 PM

I followed the link to the Pixel 9 bug/exploit and saw this:

"Over the past few years, several AI-powered features have been added to mobile phones that allow users to better search and understand their messages. One effect of this change is increased 0-click attack surface, as efficient analysis often requires message media to be decoded before the message is opened by the user"

Haven't we learned our lesson on this? Don't read and act on my sms messages without me asking you to!

by krupan

Even that's not sufficient. Consider an email client that doesn't parse images until you interact with the message. So you click on it, realize it's dodgy, but it's too late now because all the complex bug prone machinery has already been triggered.

Or my favorite, I marked an extremely suspicious message with what was almost certainly a malicious attachment as junk in a certain BigTech webmail client (the only other option was phishing which it most certainly was not) and it "helpfully" opened the unsubscribe link in my local browser without first asking me for permission. It's difficult to imagine the level of incompetence and dysfunction required to not only write but review, approve, and deploy such a feature in a security and privacy sensitive context.

Which came as a reaction to "tracking cookies" and the like being added to e-mail.

It was a reaction, not a proactive response.

by marysol5

5/16/2026 at 8:54:40 AM

Rather than tracking cookies it's a form of delivery confirmation via unique url. One of the mitigations is to configure the server to unconditionally fetch (and retain) all embedded media immediately on receipt of the message. Which makes the BigTech example all the more egregious.

Why are you withholding the name of the webmail provider?

Literally the only thing even remotely pressuring these firms to implement better security is bad PR (and it barely does that), so by not being explicit you are bypassing this

What is the purported lesson we should have learned? Users choose phones with rich messaging features. This was a major selling point for iPhone, first, with iMessage, and later with Android until iOS caught up with RCS.

by JumpCrisscross

5/15/2026 at 8:06:59 PM

One of the things Apple's Lockdown mode does is disable previews of images or links that are sent to you.

It seems like the lesson is that you shouldn't be processing data sent to the device by random strangers without the user explicitly choosing to open the file or follow the link.

by GeekyBear

5/15/2026 at 9:14:10 PM

That should be the default behavior, not a special lock down option that also disables other features.

Why can't they just make it like most email clients? No preview by default, give a banner with an option to explicitly allow a preview for that specific message or conversation?

by thewebguyd

5/15/2026 at 10:48:46 PM

I tend to agree.

But how does that prevent one from receiving and opening a malicious message?

by thrownthatway

Because many people know not trust unknown senders.

by thrownthatway

No such thing as completely idiot proof. But I think we can all agree an exploit that requires a click is a lot better for the intended victim than one that doesn't. This way they at least have a chance to not click it. Then we can start tackling the other problems with separate solutions

Sorry, but that is an insanely defeatist attitude blended with a hint of blaming users for wanting features.

Image decoders are pure functions and all should have been rewritten as 100% safe Rust years ago.

Users need functionality.

It’s up to us to figure out how to provide that safely.

Saying to users they shouldn’t have those features isn’t sage advice, it’s admitting failure.

by jiggawatts

5/17/2026 at 3:19:43 AM

Since it's a pure function, you can even keep using the legacy C code while still putting it in a sandbox: compile to WASM, then AOT transform to native code, and now it runs in the WASM sandbox at practically-native speed.

https://hacks.mozilla.org/2021/12/webassembly-and-back-again...

(Of course, new code is preferred in Rust over C, for sure.)

by yencabulator

5/16/2026 at 12:13:56 AM

The thing is, nobody's happy just previewing jpegs and pngs.

Before you know it, people want to preview SVGs, PDFs, video, HTML and so on.

And to do that properly means you've got to support obscure formats like JBIG2 and CCITT Fax. Malicious vector images with a billion elements to render. XML that lets one file embed another.

And good luck getting the budget to re-implement them all from scratch in a better language, when the only business value the feature delivers is a postage-stamp-sized preview image.

by michaelt

5/16/2026 at 1:04:56 AM

Perfection is the enemy of the perfectly good.

And let's be honest, you'll have what, 0.0001% of users who want to preview CCITT in 2026? Less? Probably less.

by amarant

5/17/2026 at 1:22:27 AM

It's a part of PDF, so if there's a PDF renderer which makes preview, it supports G4 and JBIG2.

by ValdikSS

5/16/2026 at 3:24:31 AM

The business value is reduced attack surface which is a marketable attribute. Seems like the exact type of thing Apple would do.

by denkmoon

5/16/2026 at 8:43:01 AM

At what point do we just refuse to parse obscure rarely used formats

by marysol5

5/16/2026 at 1:14:05 AM

Most of these are solved problems to one degree or another. Web browsers have generally switched over to decoding legacy unsafe formats like PDF using safe managed languages, typically JavaScript.

> JBIG2 and CCITT Fax

Since performance isn't such a critical concern with obscure legacy formats, it really wouldn't be much more than a day or two of work for a competent developer with AI agent tooling to convert an existing decoder to safe Rust.

Meta set nearly a hundred billion dollars on fire for a total failure that everybody saw coming, a trillion dollars is what the current AI investment crazy is pouring into concrete and TSMC chips, but... a couple of days for a developer is asking too much!?

by marysol5

Let's think about why that happens though

We all go through that stupid phishing training. They give us a list of red flags to help determine if an email is legit.

Then the next day, the CTO sends out an email that says IMPORTANT and the only text body says PLEASE READ THE ATTACHED .DOCX FILE. This is exactly what we were just trained not to open, but its from some exempt C-level who didn't have time to take the training, and all he is now doing is training the employees to open mails that look like phishing.

Google owns Android. Google does not care about you or other users. Their customers are ads publishers. 0days does not matter for them! Because there is hardly one alternative: iphone (and Huawei, but maybe not everywhere). Not much to care about.

We all need a new phone OS and hardware level. Urgently.

by zx8080

5/16/2026 at 8:28:10 AM

0days does not matter for them!

This does not make much sense at all and is also not in line with empirics. It does not make much sense, because if flagship Android's security reputation worsens, more high-value customers (which are interesting to ad publishers) will go to iPhone. I think this is already an issue for Google because the most popular iPhones are all flagship models, whereas the most popular Android models are low- to mid-range Samsung A series:

https://counterpointresearch.com/en/insights/global-smartpho...

This reduces the opportunity for Google to extract money from their ecosystem (Ads, Google One, etc.) and gives it to Apple.

Second, it does not line up with empirics, because after Apple, Google has been the manufacturers most aggressively pushing hardware security. E.g. Pixels have had a Titan M secure enclave for a long time now (most Android manufacturers do not have any and rely on TrustZone), Google Pixel was one of the first devices to adopt memory tagging (MTE), etc. They do a lot of work to try to reduce the blast radius of 0-days, there is a reason why e.g. GrapheneOS has so far only supported Google Pixel devices.

The problem is more the lack of privacy.

Getting users to open a message isn’t a terribly high bar. As a user I would not find it acceptable if needed to be careful with which message I open. We tried putting the responsibility on the user with email attachments and I think it’s fair to say it’s been a disaster. Malicious attachments are probably the most important distribution vector for malware.

by marysol5

It's worse, often the saying goes "don't click on suspicious links"/"don't open suspicious attachments". If I (target of such hint) knew the link was "suspicious" I wouldn't click it! Users are not opening suspicious attachments, they open (what they think is) important invoice or message from their boss.

by ffaccount2

5/15/2026 at 8:05:11 PM

Sure, in an ideal world different from this one. You should be able to do anything on any device and never worry about security.

Unfortunately, since we don't live in that world, we need to not open links, emails, text messages, etc, if they are sketchy.

A better solution may someday exist, but as of yet has not been found.

by ImPostingOnHN

5/15/2026 at 8:23:15 PM

"Don't click on links" is not a solution, and it's not something people actually do, it's just something they think they do.

Corporate Security will tell you that it's ok to click links to the payroll system or hr or vanta or the 'secure email service' or jira or github or to docusign or the microsoft office document that a partner company sent you or an amazon delivery notification, but not ok to click links in the phishing email that looks exactly like one of those that they sent you.

It's not possible to tell whether a message giving you a link to something is 'sketchy' or not before clicking the link, and any 'security' that relies on people knowing whether a message is malicious or not by magic is broken in the real world.

by kybernetikos

5/15/2026 at 10:05:54 PM

>It's not possible to tell whether a message giving you a link to something is 'sketchy' or not before clicking the link

Sure it is. It's just not something the average user can do. But what makes the situation worse is that most emails now use click tracking, so ALL links are sketchy. For example, emails from my union all link to 2mv.aplink.red and are 200 characters long and look like /dev/urandom output. No fucking idea what or who controls that domain, but it for sure is not my union. I've complained multiple times, including acting dumb and asking if they've been hacked because their email look shady as hell.

Email with the unsubscribe link wrapped in click tracking gets sent straight to SpamCop. I hate tech more and more every day.

by encom

5/16/2026 at 7:17:06 AM

I think you are providing a very good argument for why even technical users cannot distinguish legitimate links from sketchy ones.

by saagarjha

5/15/2026 at 9:52:47 PM

In my company I regularly see genuine, legitimate emails that carry several huge red flags, like these conveyed to us on trainings.

If I can plausibly claim I wasn't sure it was legit (ie it was sent from the outside form the sketchy looking host), I'd always report it internally as phishing attempt. Just to make the security work with it.

by subscribed

5/16/2026 at 8:49:04 AM

There's also something about "admin" and "HR" systems in companies where they ignore everything they told you not to do.

I don't think I've worked anywhere yet that does 2FA, SSO, or even a vaguely usable system that doesn't look like it was made 30 years ago in these departments.

Which is extra troubling as these systems are the ones with the PII!

And yet, there is currently no better solution I'm aware of, so that is what they must do.

"Just let anybody click and open anything" is not a solution, either.

I was at an "AI Security" talk recently, that centred around "While we blindly will injest inputs to and from AI, and that's a security issue. There's nothing we can do, so just deal with the aftermath".

Including saying "If a threat actor updates your internal documentation, they can use that to influence the AI".

If a THREAT ACTOR IS UPDATING DOCUMENTATION, YOU'RE COMPROMISE!

We're not talking about "Wikipedia Vandals" here

by marysol5

5/16/2026 at 9:21:24 AM

A "threat actor" can be a company employee who is intentionally permitted to update internal documentation, but not intentionally permitted to change the behavior of an LLM whose context window includes that documentation.

I think it's reasonable for a security conference to talk about how if you put the internal documentation in the LLM context, that means you're elevating the permissions of anyone who can edit the documentation by transitively giving them the ability to instruct the LLM in its "actions" (outputs).

While it should be obvious that's what you're doing, I would say most people I talk to about LLMs do not understand that all parts of the context window together shape LLM output, and there is no such thing as "only obey instructions from the system prompt".

by Borealid

5/16/2026 at 9:25:22 AM

Doesn't that just turn a 0-click exploit into a 1-click exploit? It's unlikely the user can make an informed decision to not process a potentially malicious message, without clicking on the message.

by varenc

5/15/2026 at 9:57:07 PM

Preferably a two-click exploit. One to view the message and one (if I decide it's safe) to process it through your buggy code.

A 0-click exploit is horrendously worse than even a 1-click one. I often don't even open messages from numbers I don't recognize

by greesil

5/15/2026 at 4:44:10 PM

Android vendors have been notorious about updates for a long time. Part of that is supposedly because all of the phone companies want to distinguish themselves from each other, and so they all want to fork the default Android UI so they can offer some psychedelic UI vision with some brand-specific features. But that means that when an update to stock Android comes out, it's a lot of work to migrate.

by CobrastanJorji

5/15/2026 at 6:50:43 PM

I don't think Android UI customization is the main issue. Many vendors are not even able to keep device firmware and Linux kernels in sync. Qualcomm and others are doing monthly bulletins:

https://docs.qualcomm.com/securitybulletin/may-2026-bulletin...

Since a lot of vendors are months or even years behind, their phones are full of known holes.

When it comes to security, basically: GrapheneOS > iOS > PixelOS >> Samsung OneUI >>>>>>>> everybody else.

Sadly, Samsung lets anyone who pays enough push bloatware and analytics on their phones. E.g. AppCloud from an Isreali company, Meta services that stay even when you remove Meta apps (only removable with ADB/UAD), etc. So there are only three somewhat serious options (and for two of them, you still give a lot of analytics to Apple or Google).

I turned it on a week ago to see what it was like. I expected it to be significantly annoying, but I found basically nothing changed other than a bit of text in safari that says it's in lockdown mode. Otherwise I wouldn't have been able to to tell the modes apart. I was expecting the browser to be slower without JIT or use more battery but I haven't noticed any change, it's all still snappy.

Apple over hypes the "you need to be in significant danger" part. Basically anyone can turn this on and it's fine. The UX seems mostly exactly the same either way.

This is the kind of assertion without evidence that just muddies the waters. “All kinds” of people is so vague as to be an almost entirely vacuous category and “routine” means almost nothing without an actual quantification of how prevalent and frequent the problem is.

It’s undeniable that the proverbial guns for hire make it easy (if not cheap) to target basically anyone — but just because the vibes are bad doesn’t mean we can just say “it’s common knowledge that …”

The fact is mitigations are costly in terms of convenience and ease of use. Helping people make informed choices about whether to enable mitigations and bear that cost requires more than platitudes imo

by bayesnet

LARPing is imagining that Lockdown mode protects you from state-level actors. It is frankly baffling why a industry that has been laughing for literal decades at even the possibility of stopping state-level actors just turns around and uncritically believes Apple's marketing team with literally zero support, evidence or proof except for a long track record of failure. You would think that extraordinary claims would demand extraordinary evidence.

We have seen multiple software hacks resulting in >10 million dollar payouts. Apple's bug bounty program only pays out 4 million dollars (2 million dollars (2x) more than non-Lockdown) for a zero-click total compromise that can trivially worm to take down hundreds of millions of iPhones simultaneously. Even at the low end of that cyberattack payout range that is still a >2x ROI if your successful cyberattack depends on a iPhone zero-click, with many publicly known attacks being in the 10x ROI range. Lockdown mode, at best, raises the bar slightly for commercial profit-motivated attackers and reduces their profit margin from wildly profitable to slightly less, but still, wildly profitable.

And of course I am using the Apple bug bounty program as merely a available metric with at least some semblance of objective support. There are zero certifications, audits, or analysis that Apple has even attempted that would confirm any claim of protection against state level actors.

I strongly disagree that there is no evidence that Lockdown mode is effective; there have been numerous exposed, active iOS exploitation campaigns of which none have worked against Lockdown mode. When we're trying to prove a negative, that's actually some of the strongest evidence we can get.

The economics of the device exploitation industry are completely orthogonal from bug bounty payouts; the markets only overlap at the _extreme_ fringes. Trying to use one as a proxy for the other is meaningless.

I don't necessarily disagree but a lot of chains will bail out if they find like the Norton Antivirus app on your phone so

by saagarjha

5/16/2026 at 11:52:59 AM

In this case the body of evidence is still quite powerful though, given that not only do we not have any forensic evidence of compromise from a phone with Lockdown Mode, but in all public cases where chains were RE'd back out of the forensic evidence, they don't work when tested on Lockdown Mode! So, there's even signal that the lack of forensics indicating Lockdown Mode compromises is not due to artificial targeting or detonation gates, but rather successful mitigation.

(as an aside): I'm not trying to say Lockdown Mode is infallible; I am sure phones in Lockdown Mode are or will be compromised. But it's clearly a very powerful tool, and to try to argue that it is some kind of marketing-driven conspiracy, against the body of evidence of its success, using bug bounty payout numbers (???), as the grandparent post did, is ridiculous.

That is a total strawman. The standard of “effective” being used by the person I was responding to and Apple themselves is “protects against state actors targeting you”, not “has any benefit whatsoever” or even “has a material benefit”.

Protecting against state actors is not a instantaneous property of the present. It demands durable protection against compromise by state actors who can easily spend tens to hundreds of millions of dollars on teams of hundreds for multiple years to develop novel, durable exploits known only to them. To the extent that compromises exist, they would require expected resource expenditure in excess of what state actors can deploy or are in excess of the value derivable by state actors which is going to be in the hundreds of millions to billions of dollar range to constitute as being "effective against state actors targeting you".

Protecting against state actors means secure against Iran, Saudi Arabia, China, and the NSA. That is the unsupported marketing bullshit I am calling out.

by Veserv

5/17/2026 at 12:33:49 PM

Apple is almost certainly spending hundreds of millions if not billions on software security.

by saagarjha

5/17/2026 at 6:11:44 PM

Sure, but that is not related to anything I said.

I said that “protects against state actors” means the cost of finding a exploit as generally applicable and powerful as a zero-click RCE needs to cost on the order of hundreds of millions to billions of dollars per exploit to be problematic for state actors to field.

That amount of resources is a competent team of 100 skilled individuals finding zero zero-click RCEs after 3 years of full time investigation. That could credibly be called secure against state actors, though would still not be out of reach of a real military operation as a hundred million dollars is still just the cost of a single jet fighter.

by Veserv

5/15/2026 at 6:19:14 PM

> We have seen multiple software hacks resulting in >10 million dollar payouts

This sets a nice price bar for exploitation. Is someone willing to pay 10+ million dollars to get access to your phone?

The obvious caveat here is that for a lot less than 10 million dollars someone can be hired to hit you with a metal pipe until you give up your passcode.

> click total compromise that can trivially worm to take down hundreds of millions of iPhones simultaneously

Where is the profit motive in doing this? Possibility is one thing, but a realistic threat is another.

Is someone willing to pay 10+ million dollars to get access to your phone?

Not yours specifically usually, but there is a lot of money in a general tool that law enforcement can use to read out phones. Of course, most of them focus on physical access. In the few Cellebrite reports/presentations that have leaked, iPhones would fall after a relatively short time (IIRC a few months), but did better than most Android phones (except GrapheneOS).

Also, sometimes you do not need the 10M exploit, you can buy many cheaper exploits and make a chain yourself.

The obvious caveat here is that for a lot less than 10 million dollars someone can be hired to hit you with a metal pipe until you give up your passcode

If they hit you with a metal pipe, it's likely that you won't survive even if you give up your passcode. So most likely you are protecting something or someone else. Set up a duress PIN so that you have options in that case.

by microtonal

5/15/2026 at 6:32:01 PM

... really? Zero-click RCEs can be used on arbitrarily many phones until they are discovered which usually takes on the order of months. You do not need to burn them on every individual target.

As a example of how they might be used in that fashion for profit, NSO group had a revenue of 240 million dollars in 2020. Many of their customers were governments who wanted to spy on activists and journalists. NSO group was in the business of economies of scale to democratize access to journalist devices by reusing a small stockpile of exploits across many targets with enough revenue to assure a steady stream of new exploits as fast as they were burned.

by Veserv

5/15/2026 at 6:42:12 PM

You’re right, I misstated. It’s not 10 million per exploitation, it instead limits the pool of people who can exploit you to those willing and have the ability to spend 10 million+ on an exploit.

That is still quite a small pool, and there are other network effects preventing any Joe blogs with that much capital from launching an exploitation campaign.

by orf

5/15/2026 at 6:59:33 PM

Again, no. You do not need to spend 10 million on a exploit if you are working with a company like NSO Group who sells white-glove access to target individual as a service. The cost lower bound is going to be on the order of ((cost of exploit) / (number of times exploit can be used)) and the denominator there is going to easily be in the hundreds to thousands. Of course prices are likely to be higher than the minimum due to profit margins.

To, once again, use the same example of NSO Group as it is infamous and well-documented [1]. In 2016 it was 500,000 $ upfront and 650,000 $/year for 10 devices. That article claims Saudi Arabia was monitoring 15,000 phones at a average cost of 10,000 $/phone. In [2] it was 7 million $ for 15 devices, but the upfront versus marginal cost per device is not broken down. And this was a relatively "above-board" company in the sense that they were a legitimate business entity with government deals which commands a premium relative to random unknown blackhat organization with no reputation.

And again, my original comment was discussing commercial profit-motivated attackers for which 1 million $ is easily within reach and just a cost of doing business to unlock greater amounts of profit. That is less than the cost of setting up a McDonalds. There is a vast, vast gap spanning factors of millions between Joe Schmo and commercial actors and a even vaster gap to state actors. There is no evidence that Lockdown mode is adequate against even commercial actors, let alone the vastly more capable state actors.

No, just keep the usual tax/finacial/health data on my devices.

I consider Anthropic's Mythros security bug finder mostly marketing, but other things worry me that there might be a global hack contagion: for example, a few months ago I saw in the news that an executive at a US security company was caught selling information to a hacking group.

Except for disabled Javascript compilation possibly slowing down web sites, not getting some attachments in messages, and some graphics not showing up on some web sites, having Lockdown mode set doesn't seem to affect anything I do. For dev I use VPSs with ssh set for ensuring SSH agent forwarding is strictly disabled, as are reverse tunnels.

It seems like doing little things like this make sense because it is such a tiny hassle to be a little safer.

On brand-name android devices you can count on getting OS security updates. The first-party vendor can build and push these themselves. Driver and firmware security updates are a maybe. These often have to come from an upstream vendor, who may or may not care to fix the issues.

Smaller brands often ship budget android devices and never update them.

by kube-system

Semi-related: has the rate of published exploits picked up as if late, or is it simply the fact that there’s hype around ai as security tool (offense or defense) so it’s simply in the news more often?

I just did some analysis on this last weekend, in 2024 there were roughly 100 CVEs published every day. In April we hit approximately 200 per day.

Going backwards from 2023, the doubling interval for published CVEs was approximately 4 to 4 1/2 years. Since then it’s approximately two years.

There has definitely been a rapid uptick.

Another reason published CVEs isn't a great metric is that one of the largest contributors to the number of CVEs significantly increasing in the past couple years has been that the Linux kernel now submits almost all bugs as CVEs which wasn't the case before.

by om42

I wouldn't look at the numbers. There used to be a lot of "scam" CVEs before LLMs, that weren't actual vulns. Nowadays its more popular to collect CVEs, and there is a lot of people scanning with LLMs and reporting without checking (like it was in case of cURL). These CVEs are often not verified by anyone.

There probably is more vulnerabilities found, but the amount of CVEs is not a good metric.

This is pure guesswork, I am not a security researcher, but my guess would be that AI is increasing the amount of low quality exploitable attack surface available, while simultaneously providing security researchers with an accelerant for their work.

A bit of both (it finds new things and news is hyped/blown up), and a third factor is that more people are trying to find things. The authors might have been able to do this already, because you still need to have a decent understanding to get useful work out of it and verify the results, but the shiny new toy and FOMO factors make people spend more hours on it that they'd have spent doing something else otherwise

I've seen quite a few saying that they were inspired by the previous report that is presented as "the model pointed us to it" and you get FOMO about missing out if you don't snatch bugs now as well

Hmmm... I'd like someone to double check my thinking here. I posted this exact prompt for gpt 5.5 xhigh:

```

does this look right to you? don't do any searches or check memory, just think through first principles

static int vpu_mmap(struct file fp, struct vm_area_struct vm) { unsigned long pfn; struct vpu_core core = container_of(fp->f_inode->i_cdev, struct vpu_core, cdev); vm_flags_set(vm, VM_IO | VM_DONTEXPAND | VM_DONTDUMP); / This is a CSRs mapping, use pgprot_device */ vm->vm_page_prot = pgprot_device(vm->vm_page_prot); pfn = core->paddr >> PAGE_SHIFT; return remap_pfn_range(vm, vm->vm_start, pfn, vm->vm_end-vm->vm_start, vm->vm_page_prot) ? -EAGAIN : 0; }

```

And it correctly identified the issue at hand, without web searches. I'd love to try something more comprehensive, e.g. shoving whole chunks of the codebase into the prompt instead of just the specific function, but it seems the latent ability to catch security exploits is there.

So then.... I wonder how this got out in the first place. I know I'm using a toy example but would love to learn more!

by shay_ker

5/15/2026 at 4:00:16 PM

I pasted the code into claude Opus 4.7 with no internet access and just asked it to just tell me what the function did, and it explained it and also called out the bug. I did not tell it to look for bugs:

> Observations & Potential Issues A few things worth flagging: 1. No bounds checking on the mapping size. Userspace controls vm_end - vm_start and vm->vm_pgoff. Here vm_pgoff is ignored entirely and the size is trusted blindly. If the VPU's register block is, say, 64KB but userspace requests a 1MB mapping, the driver will happily map 1MB of physical address space starting at core->paddr — potentially exposing whatever hardware happens to live at adjacent physical addresses. A defensive check would be:

by empath75

5/15/2026 at 4:31:53 PM

That's not really a fair test because you're leading the model pretty hard, even if the prompt doesn't specifically say there's a bug to be found. It's basically the same objections that people raised in the thread where someone claimed current models are just as good as mythos.

by gruez

5/16/2026 at 4:16:41 AM

I don't agree, and I'd like to understand your point of view.

To me, asking if a function has something wrong with it is just a very basic code review - something that should happen with every function. A competent, security conscious engineer would respond the same way as the model, unsurprisingly, since the model is... modelling competence.

Pretty sure the million dollars was not meant seriously. There are plenty of regulated fields in which people still participate, despite various risks of liability.

I'm generally against credentials, at least any system that would lead to loss of freedoms for hobbyists and small timers.

I guess credential requirements that only applied to specific limited contexts could work. As much as I value individual economic freedom and open competition perhaps (for example) medical, passenger jet, and certain military firmware ought to be written only by thoroughly vetted professionals with extensive track records.

But in general I think personal and corporate liability is probably the better way of going about it. I'd argue the current problems exist almost entirely due to perverse financial incentives.

I understand that, though I wouldn't stop. I'd just go much slower and radically change my methodology. Failures in other engineering domains come with massive legal consequences, and they have for a very long time. In mesopotamia if a house collapsed and killed someone inside, the builder was put to death. People still built houses in the hundreds of thousands.

It really just introduces a legal burden to prove competence and work in good-faith, and nets immense power to throw out ridiculous deadlines. Your managers are legally responsible too, and if they push beyond what's reasonable you have just cause to bring them to court in a way that you currently don't. To re-emphasize, I don't think this is a better world, but it's not unlivable.

Sure, but home builders today very rarely get put to death, and it takes a particular kind of intentional fuck-up to have a plumber, or a drywaller, or electrician placed in prison.

If I was personally liable for damages, and there was an insurance program or some sort - similar to how doctors & dentists practice - sure, I'd probably still write code, very carefully. But if there was a decent change of me spending the rest of my life in prison because something I wrote on a Friday at 4pm under some amount of stress? No thanks. I can re-train as a plumber, and stand knee-deep in shit all day.

by pavel_lishin

5/15/2026 at 3:54:02 PM

Well, one scenario would be that everybody who writes code would do so for money.

Take my friend who is a property lawyer. The firm she works for buys her insurance, because it would be insane to operate without insurance, but the only available insurance is personal insurance, it insures a specific person to do property law. So, although her day job is helping that $100Bn farm equipment company buy a $10M new factory from a $100Bn construction firm, at the weekend she is covered by that same insurance when she represents her friend buying a $500k cottage. AIUI this is a completely normal arrangement.

If that was the situation for programming, the company is going to buy your $100M exploit insurance because they need a programmer, but it's personal insurance so you could work on your Game jam game using the same insurance, and it'd be crazy to just "Go commando" if you don't have employment and thus insurance, in case somehow your "Galaga but also Blue Prince and somehow a visual novel" Game jam entry causes a $10M damages payment.

by tialaramex

5/15/2026 at 4:21:09 PM

Or it becomes standardized to have exclusions - pilots for example often have extensive insurance that covers the company when they’re flying for hire, but covers nothing if puttering around in a Cessna on the weekend.

Insurance companies are very, very good at figuring out how to identify and price risk, once motivated to do so.

by bombcar

Sure as you'd expect lawyers are better at cutting a good deal for themselves than other professions, but I wanted to cite an example where it does work out.

Also from what I've seen there are way too many GA accidents involving airline pilots for the insurers to eat that loss. They almost invariably have superior skills, but some of them more than compensate with risk taking.

It's not about lawyers cutting a good deal for themselves. Liability issues get complicated along multiple dimensions when they involve licensed professionals, even when they're day-to-day working relationship is indistinguishable from any other employee. And lawyers, even more than doctors, are at the furthest extreme of this complication spectrum. Even were software engineering to become a mandatorily licensed profession like some other engineering disciplines, there's little reason to believe insurance products would mirror those in the legal profession. I seriously doubt we'd end up in a place where employers are common--let alone routinely--paying to cover liability for work outside the scope of employment.

It's because it's simpler to insure "everything real estate" or whatever than to try to cut out exclusions for (relatively) cheap properties.

But if they noticed that they were paying out more than expected on these $500k deals, the insurance would change quite quickly.

The same thing happened with GA insurance - there was an assumption that airline pilots would be safer but it didn't really turn out as expected, because a 747 has a heck of a lot more "keep you safe" doohickeys and doesn't fly low to the ground much.

Yes, they certainly would. You wouldn't have smartphones, for instance.

I can't tell if this is satirical or not. But there are so many takes like this recently (hold the website liable for user content, hold the corporate developer liable for zero days in a project they happened to touch) that would all result in the same outcome (no more product at all) that I can't help but wonder if there's some luddite psy-op trying desperately to bring us back to a pre-Internet era in any way they can...

It does make me scared for what other dangers lurk since this was a really bad one and it was so little work to find.

Also of note: so many security issues lately have been done using AI. This report makes me think two things:

Apple's security posture with lockdown mode, memory tagging, and secure allocators is significantly better than Android. You can read some about it here: https://security.apple.com/blog/memory-integrity-enforcement...

by wffurr

5/16/2026 at 8:55:27 AM

I say this as a decades-long Apple user, but you fell for Apple's marketing. Yes, they do good in-depth security, but Google Pixel also supports memory tagging (MTE), secure allocators (Scudo), and has a mode similar to lockdown (Advanced Protection, which does similar mitigations and enables MTE).

Also, in contrast to iPhones, Android traditionally relies a lot more on safe languages like Java and Kotlin (and now Rust). Of course, iOS is improving there as well with Swift.

The issue is that all other Android vendors outside Google Pixel and to some extend Samsung are just terrible when it comes to device security.

Finally, it should be said that iOS was also compromised relatively quickly according to leaked Cellebrite presentations. The only system they could not compromise at the time was GrapheneOS, because they fully use Pixel hardware security features and do a lot of additional mitigations (including many that iOS doesn't use).

Also, any discussion of iOS should come with a fat disclaimer that by default iOS devices have a huge hole: most people use iCloud Backups (and are nudged towards it) without ADP, so their iCloud backups are not end-to-end encrypted and their chats, etc. can be requested by law enforcement. That you yourself use ADP does not really matter if the people you are communicating with don't. Also, Apple manages the key dictionary for iMessage, etc. so they could insert themselves. I would not be surprised if default non-E2E backups are a compromise in the extension of the NSA PRISM program that Apple already participated in before the Snowden leaks.

Of course, Google isn't any better, but just to say that Apple's security/privacy story is selective. Yes, they help protecting against some malicious groups and non-allied states, but they also make sure that US law enforcement (and probably some allied powers) can access most data.

I read about Pixel 9 Dolby Decoder bug, and it is based on integer overflow. It was a mistake to allow "+" operator to overflow, and this must be fixed in new languages like Rust, but it is not.

by codedokode

5/15/2026 at 3:19:40 PM

In Rust the decision about whether to pay for overflow checks or just wrap (because all modern hardware will just wrap if you don't check and that's cheaper) is a choice you can make when compiling software, by default you get checks except in release builds but you can choose checks everywhere, even in release builds or no checks even in debug.

By definition in Rust it's incorrect to overflow the non-overflowing integer types, and so if you intend say wrapping you should use the explicit wrapping operations such as wrapping_add or the Wrapping<T> types in which the default operators do wrap - but if you turn off checks then it's still safe to be wrong, just as if you'd call the wrapping operations by hand instead of using the non-wrapping operations.

That Dolby overflow code looks awkward enough that I can't imagine writing it in Rust even if the checking was off - but I wasn't there. However the reason it's on Project Zero is that it resulted in a bounds miss, and that Rust would have prevented anyway.

by tialaramex

5/15/2026 at 10:02:04 PM

I love most of what Rust does, but this is something they just got wrong. The + operator should always trap on overflow. Which Rust kinda wanted to do (hence why it does that in debug builds), but then they chickened out about the performance risk for release builds, undermining the entire thing. The result is just weak lip service to "no UB!", since debug and release still have very different behavior

I think Zig has the most interesting approach here with 3 different "+" operators (+ aborts on overflow, +& wraps, and +| saturates) along with addWithOverflow builtin. It'd probably be a challenge for Rust to adopt that at this point, but it'd be a great improvement

by kllrnohj

5/15/2026 at 4:50:23 PM

> is a choice you can make when compiling software

That is not a solution because it means the code can behave differently, and expose vulnerability if wrong compilation settings are chosen.

The functions like "wrapping_add" have such a long names so that nobody wants to use them and they make the code ugly. Instead, "+" should be used for addition with exceptions, and something like "wrap+" or "<+>" or "[+]" used for wrapping addition.

That's how people work, they will choose the laziest path (the simplest function name) and this is why you should use "+" for safer, non-wrapping addition and make the symbol for wrapping addition long and unattractive. Make writing unsafe code harder. This is just basic psychology.

C has the same problem, they have functions checking for overflow, but they also have long and ugly names that discourage their use.

> modern hardware will just wrap if you don't check and that's cheaper

So you suggest that because x86 is a poorly designed architecture, we should adapt programing languages to its poor design? x86 will be gone sooner or later anyway.

Also, there are languages like JS, Python, Swift which chose the right path, it is only C and Rust developers who seem to be backwards.

by codedokode

5/15/2026 at 10:13:32 PM

> That is not a solution because it means the code can behave differently, and expose vulnerability if wrong compilation settings are chosen.

If the software is correct nothing changes. The existence of people who write nonsense but expect you to work around that doesn't change between languages, they write crap in Swift or Python or Javascript just the same.

The long names are because there are, in fact, a lot of things you might want. Although Swift manages to take several pages and lots of diagrams to explain what wrapping is, that is in fact all their special operators do. What if you don't want wrapping? Too bad.

Rust provides saturating, which is almost always what you wanted for signal processing (e.g. audio) as well as separate "carry" booleans to do arithmetic the way you were probably shown in primary school, the wrapping most often provided on hardware and useful in cryptography among other places and explicitly cheap but dangerous and expensive but safe options. It also provides both kinds of division (and remainder), which doesn't matter for the unsigned integers but is important for signed integers and is a source of confusion and woe when languages provide only one kind or worse a mixture that makes no mathematical sense. These all need names.

by tialaramex

5/16/2026 at 7:33:09 AM

Swift does those too but correctly ranks the options by likelihood of use.

> __builtin_add_overflow Exists and it’s basically free on most CPUs out there.

This is a very C-flavoured "solution". For those who haven't seen it this involves a pointer (!) and we're going to compute the addition, write the result to the pointed-at integer and then if that didn't fit and so it overflowed we'll return true otherwise false.

The closest Rust analogy would be T::carrying_add which returns a pair to achieve a similar result.

And yeah, checking is "basically free" unless it isn't, that's not different. If you haven't measured you don't know, same in every programming language.

It's never been true that you can't write correct software in C or C++ the problem is that in practice you won't do so.

by tialaramex

5/15/2026 at 3:18:59 PM

It isn't because no ISA implements add like that, so there's always performance on the table if you check every time, and people would probably endlessly moan about how Rust is 20% slower than C on this add-heavy microbenchmark.

That said you can enable overflow checks in Rust's release mode. It's literally two lines:

  [profile.release]
  overflow-checks = true
I wonder if it would make sense for ISAs to have trapping versions of add and subtract. RISC-V's justification for not doing that is that it's only a couple more instructions to check afterwards. It would be interesting to see the performance difference of `overflow-check = true` on high performance RISC-V chips once they are available.

by IshKebab

5/15/2026 at 5:02:51 PM

I think it is 3 extra instructions on RISC-V if you add signed numbers. So 1 addition (the most popular operation) turns into 4 instructions. What are those people thinking? I generally like RISC-V but this part in my opinion, is wrong. They should just have added "overflow enabled" bit to the add instruction.

by codedokode

5/15/2026 at 9:10:24 PM

In fairness I don't think it's quite as much of a no brainer as you'd think. Firstly, when RISC-V was developed Rust was still pre-1.0. People didn't think it would amount to anything. So most high performance code was C/C++ which doesn't have checked arithmetic.

Second, it's easy to say "trap on overflow" but traps are super annoying. You really ideally would want to avoid leaving user mode. As soon as you trap to the OS you're now dealing with signals which are pretty much the worst thing in the world. The 4 instruction case at least lets you just branch to other code.

So you ideally want an "add or branch" instruction, but there isn't enough space in the opcodes for that. The fallback is flags, which also massively suck. I don't know if anyone has a great solution to this problem.

overflow check insns also in 6502 (bvs), x86 (into), m68k (trapv) - the gp was after something that wouldn't need to be checked every time, if interpreted as "no extra instructions" then that's a tall order. But the checks are practically free in modern big core CPUs since we have so much spare capacity in issue width in 99% of workloads.

by fulafel

5/15/2026 at 3:33:44 PM

It does seem like "What if we offer checked integer arithmetic operations?" is a cheaper experiment than CHERI's "What if we mechanically reify extent based provenance"?"

by tialaramex

5/15/2026 at 9:04:43 PM

But also way less impactful. It would solve maybe 20% of serious security vulnerabilities whereas CHERI solves like 60% at least. More if you use its strong compartmentalisation capabilities (heh).

That said, CHERI is super complicated. Checked integer arithmetic operations would be way simpler.

by IshKebab

5/16/2026 at 12:36:14 PM

Huawei fixed it in their Cangjie language. According to the docs [1][2], it throws an exception by default and you can use an annotation to get wrapping or saturation instead.

(Cangjie seems like a pretty nice language in other ways as well. Similar to Kotlin with some improvements and no Java. Bootstrapping the toolchain from source seems difficult though.)

I've been using this as a touchstone for whether or not we are actually going to take security seriously for a long time.

We've moved slightly closer to this, but in a world where we're still arguing over memory safety being necessary we've probably still got a ways to go before we notice that addition silently overflowing is a top-10 security issue. It's the silent top-10 security issue, I guess.

I hope the average person will soon understand the importance of security and will be OK with making the necessary sacrifices to achieve it. Almost everyone has something to protect, be it personal information or property (money, IP).

People love new technologies and features that make their lives easier, but so far only a small subset of these people have made a conscious decision to limit their exposure to risk by depriving themselves of benefits provided by some of these features.

It sure is wonderful to have your whole life digitized on a single computer. You can analyze, share, organize, gamify, record and so on every aspect of your life instantly and effortlessly. It's incredible, really. Technology is amazing. Expect for the pesky bad actors that can do the digital equivalent to most physical crime from the other side of the world anonymously without you noticing.

It's like germs - if you don't wash your hands after touching something questionable and you don't experience any negative consequences, you'll learn not to wash them most of the time. It's just a waste of time. Maybe if you've touched something really gross, you'd wash them, but that would be the exception. Security is the same. If you've been using computers the same way for years, you'll learn nothing bad happens so why bother having a hygiene, why bother making any tradeoffs?

Yes, you've heard the news of someone's nudes posted online, of someone's bank account drained or of some company's files ransomed, but you've also heard of something dying from a brain parasite after touching a muddy puddle and rubbing their eyes afterwards. That happens rarely, we shouldn't worry about it. A car can hit you when you cross the street, a lightning can strike you when you're just walking about, an aneurysm can end you at anytime. No one is washing their hands all the time or constantly trying to minimize the streets they cross or anything like that. That would be foolish and impractical, and I agree.

That mindset is carried over to digital security, sadly. The risks are higher, the effort to keep a good hygiene is lower, the ability for bad actors to completely fuck you is much greater than in meat space. The rewards are seemingly greater, too, until we realize that what we get from technology is just marginally better than what we get without it. Tech is amazing, but it doesn't make us transcend time and space. It let's us organize our schedule, tag people and places in photos and summarize chats. All of that is born out of meat space. Without tech we'd still have conversation, we'd still see new places, we'd still have calendars and todo lists. We get maybe 1% more than we would have if we didn't have any tech but we let all our information and property sit unsecured for that 1% gain. That's fucked up, because the risks are big and will get bigger. And the tradeoffs we have to make to secure our digital lives may seem annoying, but are actually quite trivial. Less unnecessary sharing, more isolation and compartmentalization, different computers for different tasks, less proprietary hardware and software, etc.. We could get 90% of that 1% benefit from tech if we spend just a bit of time and energy of securing out digital lives. But fuck it. Let's but the latest flagship, let's use it for ID, banking, communication, file storage, camera, health tracking, everything. Because it's a tiny bit more inconvenient to get multiple computers for different purposes, to not get the latest and newest, to not install a bunch of unnecessary shit, to be careful about the digital realm at all.

Not really on topic, but a rant. I'm tired of people (friends and friends of friends) complaining to me that they got majorly fucked one way or another and acting like the universe owes them not to get fucked while they buy a computer that exposes their asshole to the world.
