I saw this coming from miles away. Computers are better at solving CAPTCHAs than people are and people can be bribed or convinced to join botnets so IP whitelisting doesn't work either. Now we have tons of fingerprinting and behaviour analysis but governments are cracking down on that. Plus, YouTube had a massive ad fraud problem with ads being played back in the background in embedded videos, so their detection clearly wasn't good enough.

There aren't many good ways to prove you're not a bot and there are even fewer that don't involve things like ID verification.

Their opt-in approach helps shift the blame to individual web stores for a while, so who knows if this will take off. But either way, in the long term, the open, human internet is either going away or getting locked behind proofs of attestation like this.

Apple built remote attestation into Safari years ago together with Cloudflare and Google is now going one step further, as Apple's approach doesn't work well against bots that can drive browsers rather than scripted automation tools.

Luckily, their current approach can be worked around because it's only targeting things like stores now and you can buy things from other stores. Once stores find out that click farms have hundreds of phones just tapping at remotely served content, uptake will probably be limited.

It'll be a few years before this is everywhere, but unless AI suddenly isn't widely available anymore, it's going to be inevitable.

Whether it's AMP or manifest 3 or android source shenanigan or attempts to replace cookies with their FLOC nonsense or this...Google is rapidly turning into a malicious force when it comes to the open internet

I strongly suggest people move away from chrome. They lost all sense of respect.

I know it is a small move, but as it happened when chrome started, this opens opportunities for other players

Exactly my thoughts. I am unfathomably angry and I want to contribute to any effort to dismantle Google as a company.

From "Don't be evil" to building the largest, most invasive, surveillance operation the world has ever seen.

That was true before this, but this indicates nothing will ever be enough. Google will always want to track more of everyone's activity online, and will use every tool at their disposal to do it.

Very funny that if you want to start a bot farm you also go and buy a bunch of random android devices.

Why should I even care anymore? I no longer need to access random websites to find information since I can just ask the AIs.

This is truly disturbing, and trying to sneak it in like this without public discussion is disingenous. Hopefully it will be shot down like last time - at the very least, there are surely antitrust issues here.

We see the fundamental forces of capitalism at work: To justify valuation, Google needs to grow. When they feel a ceiling, they broaden their search to anything legal that makes customers pay - even if it contradicts their longterm interests. This created countless attack angles for startups. The good news: we already have a solution! Monopoly laws. In case of the internet, no company should be able to have this much power.

The bad news: US decided to weaponize big tech’s leverage over the world and does not enforce these laws anymore that fix vanilla capitalism.

Maybe a dumb question, but how is this suppose to work for iphone users? They wont have google play, and it seems like android/google play is required here? There is no way they would cut out such a huge chunk of the market.

For merchants who don't want geeks as customers, cool

As a web-wide captcha replacement, not cool

I think the idea is good if it could actually curb bot traffic that currently plagues the Internet.

However, a lot of recent bot traffic are sophisticated scrappers called "LLM's." You can tell claude to "research X from this www.example.com" and will automatically scrape it and summarize it, something that a LLM is perfect for. Gemini tends to share links instead, presumably because most of Google's revenue comes from ads served on those websites, so if it completely killed the traffic to those websites it would just make less money. Incidentally, I wonder if Claude/Gemini use an search engine-like "index" of all websites or it refuses to cache anything to always fetch "fresh" data.

If this is employed, I don't think the web is only going to be gatekept to Google devices. I think it will also be gatekept to Google's AI's.

Google would be able to display a captcha that no LLM could defeat, and then just let its own LLM pass through.

The same could be said about its other bots, such as the web crawler. Google's bot could crawl webpages that no other crawler would ever be able to simply because it has free pass to captcha-gated GETs. Although the same could be true already today.

We do need to abandon the reality where we use the same few companies on a daily basis and get back to what's now hidden the under-the-surface: forums, blogs, personal websites. We need to re-discover the "free" internet we used to have before Facebook and smartphone dystopia happened.

In a world where everything is shit, could I at least take away some solace in this helping to reduce Cloudflares hegemony?

This is security theatre. This isn't going to help against bots in any way.

This article is full of false assumptions.

For example: > Bot operators point a camera at a screen, a trivial automation with off-the-shelf hardware. For operations that need Play Integrity attestation specifically, a compliant Android device costs approximately $30 at current market prices

A bot farm cannot bypass for long with a $30 phone. Do you seriously think that if Google sees the same hardware identifier 1000s of times a day they are not going to consider that usage to be fraud?

I appreciate that Google's made a real proposal to avoid the web becoming bottomless AI slop. This article hasn't come with a better alternative - I'd love to see one!

But but but but ... now that huge tech has declared copyright invalid because of AI they must prevent you from copying Mickey Mouse! Urgently.

Of course courts will undo their current copyright stance as soon as someone "uncopyrights" Disney movies, which is of course coming, but for now ...

Will SOMEBODY think of the billions?

AI use is far more prevalent now than then sadly. This kind of scheme is inevitable since compute is not free.

Given all the negative comments here - what is anyone's alternate solution for AI-driven fraudulent activity?

CAPTCHAs are increasingly ineffective. Services are either going to go offline or implement some kind of system like this. PII like credit cards or SSNs aren't enough because those are regularly stolen.

So where do things go? Fewer services and infinite fraud?

I think this is the third HN link I've clicked on in a row that leads to an LLM-generated article. I'm not opposed to AI, but I'm tired of seeing it quietly substituted for human thought and expression.

As much as I hate whatever google's doing, this article has some issues:

>For operations that need Play Integrity attestation specifically, a compliant Android device costs approximately $30 at current market prices

This assumes the logic on google's side is something like `if(attestationResult == "success") allow()`, but it's not hard to imagine the device type being factored into some sort of fraud score. For instance, expensive devices might have a lower fraud score than cheaper devices, to deter buying a bunch of cheap devices. They might also analyze the device mix for a given site, so if thousands of Chinese phones suddenly start signing up for Anne's Muffin Shop, those will get a higher fraud score.

>Firefox for Android does not appear in Google’s stated browser support list for Fraud Defense.

The browser only needs to show a QR code, so if you're on firefox mobile they'll either open a deeplink to google play services on the phone itself, or show a qr code.

>One human solving a single challenge pays a negligible cost. A bot farm running concurrent sessions faces exponential compute costs with each additional attempt - and AI agents, which consume GPU cycles to operate, face identical penalties regardless of how sophisticated their reasoning is.

PoW for bot protection basically never caught on because javascript performance is poor, and human time is worth more than a computer's time. An attacker doesn't care if some server has to wait 10s to solve a PoW challenge, but a human would. An 8-core server costs 10 cents per hour on hetzner. Even if you assume everyone has a 8-core desktop-class CPU at their disposal (ie. no mobile devices), a 6 minute challenge would cost an attacker a penny. On the other hand how much do you think the average person values 6 minutes of their time?
