Not sure, but I struggle with skepticism for anyone who blocks archive.today, which cloudflare does, along with nextdns and others. Being blocked by such a large... apologies in advance for 'lack of better word' vernacular, cartel, is a near death sentence.

Chu4eeno3• 9 days ago

Yes, this is something almost all other anti-bot/fraud prevention solutions already does, and there are already bypasses developed simulating human mouse movement.

I expect this will be effective for maybe a day.

sudb2• 9 days ago

Cool product launch, though it feels a little weird to me that Cloudflare sells agentic products alongside this new service that seems designed to block agentic usage of the web?

I expect there's much more going on than just mouse path detection but I can imagine that this is already tricky for touchscreens and for people using non-traditional mouse inputs (the thinkpad nub comes to mind - but it would also be bad optics to accidentally block people using accessibility mouse tools as bot users, though then this becomes a loophole for agentic browsing!)

In general though I think this is almost definitely a good thing to reduce agentic bot abuse & spam.

skybrian5• 9 days ago

It’s less weird if you think there’s a difference between good bots and bad bots. They can provide services for good bots to use while helping people keep out the bad ones.

If a bot is simulating mouse movement but doing it badly then that’s a strong signal of shenanigans. A good bot will obey robots.txt and do nothing to hide that it’s a bot.

pryelluw• 9 days ago

Who gets to decide what is a good bot?

mcmcmc2• 9 days ago

The problem is they have a strong incentive to consider any bot they get paid to host as a good bot, and they can bully competitors by declaring bots they host as bad bots

What prevents bots/agents from just adding "jitter" to their movements that mimics how humans move their cursor?

I know there are other signals being used but this one in particular seems like it wouldn't be hard to beat with a small amount of sophistication from the bot.

stogot• 9 days ago

In 2027 how many tokens will we spend to create the jitter, pre-jitter planning, post-jitter verification, and then cloudflare’s inevtiable counter-jitter

Someone needs to vibecode a "virtual mouse" tool for the agents to steer instead (semi /s)

"We got this Trace-Buster-Buster-Buster that's gonna bust the Trace-Buster-Buster and bust their .... uh, uh, uh ... Trace!!"

kypro• 9 days ago

There's always been an arms race in anti-bot technology and more sophisticated bots.

I'm sure, they can add a jitter, but then you just change how you detect / weight detection.

fwlr2• 9 days ago

The jitter you add has to specifically be “jitter that mimics human cursor movement”, which is extraordinarily non-trivial to synthesise.

SAI_Peregrinus2• 9 days ago

No, it's "jitter that mimics human cursor movements detected by Cloudflare's Precursor script". It'll just be another arms race.

justinhj• 9 days ago

are you sure it's non trivial? they posted a 2d image of what it looks like. a fairly simple model of the users wrist and mouse position doesn't seem crazy hard but the devil is in the details

nerdsniper3• 9 days ago

Beating this would require a large amount of sophistication, not a small amount.

Basic machine learning clustering will expose bots mouse+keyboard+touch behavior and discriminate them from humans.

It will also likely discriminate against anyone with a disability and therefore using affordances like eye tracking. Just imagine how different a person with only one hand would look compared to a “typical” user!! This shouldn’t be too much of a problem in the USA because no one is enforcing the ADA at the moment outside of California / Illinois / NY.

But I’m curious to hear from ‘eastdakota how they plan to guarantee that users with disabilities won’t be affected by these kinds of behavioral analysis. Cloudflare has such a massive footprint that it’s absolutely critical for them to err on the safe side of filtering, assuming they desire to be ethical.

The immoral thing for cloudflare to do would be to say “we just provide a ‘bot likeliness score’ and it’s up to each website to decide what threshold they need”. And then wave their hands and say “we’re not the ones blocking users with disabilities…the websites are the ones setting their thresholds too strictly”.

When you reach Cloudflare’s size … you own all the 2nd and 3rd order effects of your decisions.

This kind of data not only separates bots from humans - it’s pretty trivial to distinguish male vs female, right-handed vs left-handed, approximate age, native language (based on keyboard input patterns), state of injury (including tracking progression of healing), and a variety of different mental/physical disabilities. How one navigates a website tells you whether they are ADHD or schizophrenic or has Parkinson’s, and it can tell you about drug use/abuse: how well is this person’s Parkinson’s treatment working? What days of the week does that person tend to abuse amphetamines?

It is super difficult to mimic all of these signals in a way that would cluster the same as typical humans.

SoftTalker2• 9 days ago

We used to say the same sorts of things about LLM prose, music, and image generation. Now just a few years later it can be very difficult to know for sure if something is made by AI or a human. There are still tells, but they are much more subtle and harder to spot, and models are still improving. Mimicing human mouse movement won't be any more of a challenge.

lossolo• 9 days ago

It is super difficult to mimic all of these signals in a way that would cluster the same as typical humans.

Not really, beat ML with ML. I won't disclose how to do it, because who knows who might read this, but you can easily do it with a model trained for that purpose.

zuzululu2• 9 days ago

Nothing. But you are already at a disadvantage because Cloudflare has seen far more real jitter data and you are up against that. It might work in the short term but after a while you start showing pretty obvious patterns. There's also a great variety of jitter data on specific websites or layouts that would be very easy to catch someone artificially emulating jitter

stronglikedan• 9 days ago

Does anyone besides me try to beat the jitter to fail the captcha? It never works, and yet I continue to try.

They're creating optional opt-in protection layers for the services they operate.

I genuinely don't understand these generic complaint comments.

Are you complaining that they offer too much? Or do you believe nobody is offering similar services?

stuartjohnson122• 9 days ago

The complaint is that the offer is a great deal with no downsides for consumers, and this is likely to result in Cloudflare having a lot of power (which they currently don't have) as a market maker. This position as market maker would grant them the power to extract economic rent from the web economy by charging both sides of the web provider and web consumer market to get access to the other.

dzonga• 9 days ago

have you considered the alternative ?

where bots run rampant ?

trust me as an operator - I'm grateful Cloudflare exists.

postalcoder• 9 days ago

Gonna zag here. If you take a step back, cloudflare has been paving the path for pay for crawl. I think it's a noble and ambitious goal.

While I can understand why you would be alarmed, I can point to almost two decades of lamenting on this forum about how we need better ways of rewarding content creators than ads. Well, this is it.

Moreover, these products weren't built in a vacuum. Most threads about Anthropic and OpenAI have complaints about how these companies were built on stolen content. There's a reality we have to face here and we can't have it both ways.

halJordan• 9 days ago

Is it a better way though? The problem with ads has always been their abusive nature. From unrestrained pop ups and clickjacking in the 90s to today's pervasive surveillance and profiling.

Cloudflare turnstile is a pop up. This product is pervasive surveillance. It having a cf logo doesn't change that or ameliorate the many many abuses that two decades have shown are part and parcel.

RedRocketFlash5• 9 days ago

What's incredible is that you have businesses paying CloudFlare to stop their content being ingested by AIs (OpenAI, Anthropic, Self-operated scrapers).

And at the same time, they're paying SEO experts to make that same content easier to be ingested by systems (Google and other Search Engines) which use it for their own AI offerings.

Are you going to be able to make your online content available to Google Search but unavailable for Google Gemini?

whatjustin• 9 days ago

Unfortunately a common occurrence in the world. Not really a fan of cloudflare selling to both sides.

LoganDark2• 9 days ago

It's really telling that they're starting to block anything automated ever that hasn't gone through their ID verification process. It's like literally every company that exists in the world is taking advantage of the dystopia at once

mark2122• 9 days ago

no, they're giving tools to their customers who can choose freely to block or not block bots. Without those tools, the people who run sites and offer content are just flying blind. I struggle to see how this is a bad thing in any way

timcobb• 9 days ago

freedomben• 9 days ago

As a real user who uses an Ultimate Hacking Keyboard with the mouse layer, this frustrates me immensely. Yes I'm a corner case, but this is likely to make certain website not work for me because my lines are perfectly straight and my arcs zig-zag much like a bot might.

Considering the keyboard/mouse layer feels like an advancement to me, this feels like tech that will lock in the "old" way of doing things.

I really detest how adversarial the web is getting. I'm not a cloudflare hater but please, please consider people like me when rolling out stuff that affects millions or maybe even hundreds of millions or billions of people.

bigbuppo6• 9 days ago

Yeah so this mouse movement astrology is going to completely lock non-sighted/keyboard only users out of large swaths of the Internet isn't it.

sudb2• 9 days ago

I'd imagine that mouse movement is just one signal among many that's weighted appropriately, but I hope we get feedback from these users

abirch2• 9 days ago

I'm guessing it's going to lock the non-sighted//keyboard only users out of the anonymous Internet. I'm guessing if you log in and give up your anonymity they'll consider you not a bot.

thomastjeffery2• 9 days ago

Cloudflare has a lot of enterprise customers. Selling bot check to companies wanting to protect their content & also taking a cut out of payments for access by bots could be a good earner for them.

csomar• 9 days ago

So now instead of having the slow-axx Cloudflare turnstile slowing down your requests, you get surprised with a "You are a BOT!!!" while you are conducting your business on a website.

I already quickly close any website that I do not need for business purposes when it shows me the Cloudflare spinner. Now I might have to start considering competitors who do not implement this shit.

pocksuppet3• 9 days ago

Turnstile already does the "You are a BOT!!!" thing btw, if it thinks you're a bot, which is quite rare as it seems much more permissive than systems like reCAPTCHA.

carterschonwald• 9 days ago

even before the llm era sites would flag me as a bot for opening 15 links to read later. its fucking infuriating now

TrackerFF• 9 days ago

One interesting aspect is of course that the movement from the same user can be different depending on what type of mouse they use. I use a mouse at work on my PC, touchpad on my private laptop, and thinkpad nipple on work laptop. Three different profiles for one user.

Obviously different movements from a AI, but if we come to the day where mouse movement fingerprinting becomes another gatekeeper, there could be some interesting outliers.

dinkleberg• 9 days ago

I wonder how it'll handle those of us who try and use the mouse as infrequently as possible. I imagine the cognitive delay part would be largely telling. But it'll be interesting to see if I start getting blocked because I use vimium.

SoftTalker2• 9 days ago

I think it doesn't really matter, the bots will adapt with much more human-like mouse movement very quickly.

dubcanada3• 9 days ago

There is nothing stopping a bot from moving their cursor like a human. This is basically just putting up a door with zero walls and telling people to stay out of your house.

All of these things are completely abusable/bypass-able and just annoying for actual humans who trigger flags.

swiftcoder• 9 days ago

There is nothing stopping a bot from moving their cursor like a human.

Sure, we could write a library that slows the bot down and makes it move the cursor in procedurally-generated curves with a certain degree of noise added... but its all extra work, and it all slows the bots down. Presumably they wouldn't reveal that part of the secret sauce if it was all of the secret sauce

dubcanada3• 9 days ago

Acting like a human is something scapers already do. Using residential proxies, using latest Chrome user agents, not moving/typing as fast, etc. This is just 1 more layer, moving mouse naturally.

tavavex• 9 days ago

It's a bleak world in terms of bots flooding the web, but out of all possible solutions, this seems to be preferable over invasive and identifying fingerprinting that everyone wants to roll out. Here's hoping that mouse movements aren't sufficiently unique as to be fingerprintable too.

whimsicalism• 9 days ago

as a heavy user of computer use, i hope enterprises realize that people like me will switch to competitors that support native computer use & APIs

amirhirsch2• 9 days ago

I implemented all of this in hCaptcha 6 years ago, not just to distinguish bot from human but also to recognize the keyboard/mouse behavior of the same person signing up for many accounts or testing multiple credit cards. This kind of abuse detection was a part of Cloudflare when they switched to hCaptcha in 2020 and I had thought they already implemented all this themselves four years ago when they transitioned away from hCaptcha in 2022.

Chu4eeno3• 9 days ago

Didn't recaptcha v3 also do this? iirc the "silently monitor in the background" was part of the selling point.

amirhirsch2• 9 days ago

Yea this is the premise behind all the invisible captchas, combined with browser fingerprinting. Same tech is used now to detect distillation rings.

trunnell• 9 days ago

I dislike bots as much as anyone else... when weird inquiries come through my company's lead form, it costs some time and attention to sort them.

But what makes Cloudflare so confident that automation always equates to "fraud and abuse?" If I send my agent to go retrieve some information, do they consider that fraud?

If I block various ad trackers does that trigger their "bot detection" incorrectly? Do I have any recourse? Or is Cloudflare appointing themselves judge, jury and executioner?

And let's not forget this little chestnut: > 4. Privacy by design. Precursor was designed to collect signals that help to distinguish human patterns from automated and abusive patterns.

Ahh, so to "protect" against bots they're standing up a whole new regime of user surveillance and session-level monitoring. And they definitely won't be selling that, they promise. Got it.

This crap should be illegal. In the real world, I can authorize others to act on my behalf. The same should be true with software agents.

bellowsgulch• 9 days ago

Yawn. Train a domain-specific model on human inputs and then run inference against that. At integration, you change what, one line of code with another? You at best raise the expense to bot, but in today's world, this isn't much compute expense. You can do it on 10-year-old Xenon processors, the same ones used by companies promoted on LowEndBox.

Skids already fall into the trap of using open source automation like playwright-extra-stealth.

erikvanoosten• 9 days ago

Your keyboard and mouse rhythm and timings are probably so unique that they can be considered PII. Wonder how that works out legally.

zuzululu2• 9 days ago

hmmm i think this is the first time i've seen a genuinely decent approach to blocking scraper/agents

that mouse cursor movement is very hard to replicate a real human with the amount of data that cloudflare has you could reproduce something close but cloudflare has seen probably trillions of movements that will be tough to beat

watching this carefully but i think this is the right approach

cjbarber2• 9 days ago

This (agent detection) is now a kind of emerging space. Obviously it'll get much more important, too.

Other products in the space:

- Foil (https://usefoil.com/), I'm biased, a friend is building this

- Kasada https://www.kasada.io/

- DataDome (https://datadome.co/)

- Castle (https://castle.io/)

- Fingerprint (https://fingerprint.com/)

- HUMAN (http://humansecurity.com/)

- Google Cloud Fraud Defense, which is basically the updated reCaptcha (https://cloud.google.com/security/products/fraud-defense?hl=...)

- this, Cloudflare Precursor

It seems like some of the main reasons people care so far are:

- Preventing automated credential stuffing

- Preventing bots from creating a bunch of fake accounts (eg free trial abuse, which can also lead to high twilio SMS bills!)

- Reducing payment fraud

- Blocking LLM scraping

- Blocking automated scalpers (!) eg for tickers or sneakers

I'm curious to see which use cases end up dominating as the reason companies care about this. And I'm hopeful that my agents will still have good ways for me to browse and do things on the web on my behalf - eg detect agents and route them to an agent path, rather than blocking them.

(I'm interested in tools for detecting AI agents and seeing how this shifts as bot traffic goes way up.)

harrylepotter• 9 days ago

Darwinium (darwinium.com) is another example. Approach here involves a combination of profiling and step-transition probabilities; idea is that a customer can ring-fence a particular area of a digital estate where they might want to challenge or block an agent - eg a payment, due to chargeback risks. Precursor at least for now seems more focused on site scraping multiple docs from the same site.

lukewarm7073• 9 days ago

happy to offer a counter of some great products for anti-bot defeat:

hundreds of millions of residential ips, human browser fingerprints, custom browser binaries, auto solve of turnstyle, recaptcha v3, kasada, datadome, AWS WAF, etc if they come up.

cjbarber2• 9 days ago

Bright Data ranks #1 on Foil's leaderboard [1], but is still detected. ScrapFly is #4 and ZenRows #7. And I guess Capsolver isn't really a scraping thing but is more just for the captcha component.

I think it'd be good if there were more products that did a better job of making an actually undetectable agent, but doesn't seem like any exist yet.

The examples of mouse movement, really reminds me what bot scripts looked like for Runescape back in 00s-10s. Early scripts were color-based and jumped the mouse around, and those were quickly caught. But over time, bot scripts developed into complex orchestrations; taking breaks, doing random actions spontaneously, moving the mouse naturally, logging sessions on different platforms (mobile, PC), even responding in chat.

There's been plenty of effort put into mimicking realistic / "human" behavior in writing video game bots, and every video game still has tons of bots despite the best efforts of the game devs.

You definitely can't win against bots - but you can definitely make the entire "game" (web at large, in this case) worse off for everyone else through this "always-online DRM" parallel.

altairprime2• 9 days ago

I can’t wait for Cloudflare to decide my musical-rhythm enhanced typing and extraordinarily rapid and repeatable-pattern captcha clicking are somehow machine signifiers just like Google does: If I complete Google captchas at full speed it decides I’m a robot and challenges me endlessly, once 29 times in a row in two minutes or something. That’s what I get for having excellent spatial reflexes and mouse-clicker practice from Q3A sniping. So exhausted of the reversion to mediocre tendency of anti-bot systems, sigh.

bigbuppo6• 9 days ago

You also screwed up by using Firefox. That's the #1 method Google uses to prove someone is a bot. If you are't participating in the Google panopticon, you are suspect.

piterrro• 9 days ago

I think in 10/20 years from now, access to the Internet will be allowed only upon personal identification. Every website will be allowed to ask about your identity upon serving any content. Thats the only way I see this is going. The internet as it is right now does not have a future if majority of traffic will be done by agents. Thus, the cost of that traffic will have to be put on the users and since displaying ads doesnt make sense to agents, a paid access will be introduced (which is what cloudflare is slowly doing)

yencabulator• 9 days ago

How about we make browsers not report mouse movement to the page? This is getting way too creepy.

stanfordkid• 9 days ago

I'm sure they are doing more than looking at mouse movements, but I don't think this is a compelling approach -- I think human movements could be faked pretty easily using a large corpus of real world behavioral data. It's an adversarial game but the level of intelligence we are approaching with AI this can be solved IMO.

nikolay• 9 days ago

Honestly, you need to be completely out of your mind to use Cloudflare for anything. These guys don't offer any support. They seem like a lucrative option until they start blackmailing you into paying for Enterprise, since anything else is a joke.

hirbyturby• 9 days ago

Ultimately, I think a lot of this is for naught. As models get better and smaller and move from the data center to the PC and the phone, end-user agentics are going to become more prevalent. Bots and agents will be the standard way that people interact with your products. Products that can't or won't allow it will die.

mchusma• 9 days ago

I would say that overall there are pros and cons to this, I really want to be allowed to use agents on my behalf, and don't want to see sites prevent me from doing this. On the other hand, I do recognize there are cases when its good/ok to have only humans allowed to take some action. In my opinion, the line is likely when you are representing you are a human, its ok to prevent bots. otherwise, you can't.

boesboes• 9 days ago

JJvb89• 8 days ago

This is frankly just ridiculous. Tracking mouse movements has been a basic bot-detection signal for 15 years. Cloudflare just added it as a signal and is making a huge deal out of it.

A firewall company knows very little about browser internals so don't expect much from this.
