From experience: this does happen regularly in some neighborhoods of some cities in the US, and even that isn't always an enforcement priority.

You still can.
Just build your website yourself as deep in the stack as you can instead of piling up 50 abstractions on top of each other. Some decisions like having your page be accessible by IP can only happen if you use technology like generic http servers (like apache or nginx) from the 2000s instead of implementing the lower stacks and actually thinking about whether that makes sense for a second.
If when you build a website or a backend, your server responds to requests by IP address (for example), you are building a bottom 90% product, and considering most software markets are super top-heavy, (say 1% win), that's ngmi land.

On average about 100 (TCP) requests hit my home router per minute doing various probing and scanning. Lots of checking for the telnet port obviously. Sometimes you can see a swarm of entirely different IPs scanning the full port range (probing the ports one-by-one).
You'll see a lot of deepfield, censys-scanner, visionheight.com, shadowserver.io, etc., but also the usual suspects of Chinese or Russian IPs.
With OpenWRT I use something like this: `tcpdump -i pppoe-wan 'inbound and tcp[tcpflags] & (tcp-syn|tcp-ack) == tcp-syn'`, or alternatively `tcpdump -i pppoe-wan 'inbound and tcp[tcpflags] & (tcp-syn|tcp-ack) == tcp-syn and not port 44000'`, if we have some torrent client running (e.g. here at port 44000) which would mess up the result. I'm not sure it's the best way to handle this, but it's definitely enlightening what bounces off on the router.
miah_ 9 hours ago [-]
The easiest way to deal with the usual suspects is to just block the entire countries network range(s). There really is no reason they should be connecting to your home router anyway, and you lose nothing from blocking them.
Sure their packets will still hit your router, but if they are dropped immediately at least you're not wasting a syn-ack on them.

Thanks in advance.
thesuitonym 8 hours ago [-]
Your router doesn't care about their DNS settings. IP addresses are very easy to tie back to countries. The reason they say it's not reliable is because it's trivial to spoof the country, but even so, a lot of attackers don't even bother. It's sort of like the Nigerian prince scam calls: if you're wise enough to block Russia, you're not worth their time.
Your firewall vendor should supply you with country lists, just select the known bad ones and drop their traffic. If you have a consumer grade router, you will probably have to configure the blocklists manually.

Many of those user-agents listed are often faked. Look up which ASN owns their IP. If I block most VPS providers most of the faked bots vanish. There are still some running from residential and phones using hijacked code (readers that are not really just readers but really multipurpose proxies). On that note, do not trust the linked source code but rather decompile the live code your phone is running and have AI analyze it.
cullenking 3 hours ago [-]
I did just this. Using a $2k a year database from a smaller provider that isn't maxmind, claude and I built a pretty slick ASN based categorization system. I can categorize an ASN as a residential IP, a service provider, a legit crawler/scraper, etc. For anything that is suspicious, I dynamically use turnstile to gate access to our service. Turns out there's no ISP for any VPN, they just contract with a shitload of mom and pop shady colocation services across the world.
We collect signals that help determine good vs bad networks. For example, large amounts of requests to .php endpoints, large amounts of empty accounts from the same /24 subnet, etc etc. All these signals let us automatically determine risk, and then put up a challenge. Authenticated users never see the challenge even if they are on a risky network (VPN 99.9% of the time), unless the network has been identified as 100% malicious, then it gets a full block.
This was probably a total of 3-4 days of work, spread out over a couple months of iterative claude led hacking. I didn't know exactly what to build, but had some of the key architectural ideas in my head. Opus+Faable made easy work of it all, and ended up guiding some really slick improvements for performance.
I would say this has dropped about 20% of all traffic to our service, though it turns out turnstile is a massive target for bots, so replacing that with something custom is next on the list.
inigyou 43 minutes ago [-]
Contracting with their colocation facilities is exactly how that's supposed to work. If you don't actually operate a wide area network then you aren't supposed to be registered in these databases and have IP blocks. The exception is people who do anycast, but VPN companies don't.
You know all these guys just switch to residential proxies if they detect a site is blocking data centers, right? Because that's a very common thing to do.

I run an open source honeypot that collects these botnet scans and produces blocklists.
Cool site. I was curious and dropped your 100k list into a reverse DNS lookup site [1]. They may still have some of the records cached. I recognized quite a few of the scanner nodes and some other usual suspects.
Yeah, that’s pretty interesting! You can also see a live view of the ASN/ISP leaderboard by going to https://knock-knock.net and choosing ISP from the carousel. That’s ordered by bot transaction count rather than IP count though.
It never ceases to amaze me that these ISPs don’t bother to shut down the botnets. They could do so very easily. For example, they could identify the IP address of every bot that hit this honeypot with their ASN with one API call: https://api.knock-knock.net/check-asn?asn=<asn number>. (See https://knock-knock.net/api). They just don’t care!
Bender 5 hours ago [-]
The ISP's do not have a financial incentive to shut them down. To them that's a paying customer. The feds will go after the big botnets if they are touching financial networks or siphoning enough money from people because there is usually a few big bank accounts and virtual currency exchange accounts they can seize once big enough to look good in the media. That's why it's on us and a few big CDN's to block some of them.

There are several methods. [1] The most aggressive method-02 and method-03 on my document will block VPS and some data-centers but that also means it will block some legit users that are on a VPN. Most VPNs transit a data-center. If experimenting with these methods use a test server that you do not care about and set up a dummy site and ask people in your circle of friends to test it. I have to step away for a bit but if you have questions I will try to answer.
Your site does not currently seem to be reachable / responsive when I try to reach it from a US Comcast IPv4 address - you are not advertising IPv6.

You can block entire ASNs. If you are frustrated with bots, blocking Tencent's entire IP address space would have very few downsides.
If you have fail2ban or NGINX logs, you can use our CLI to summarize those IPs and identify the ASNs you want to block. But before you block entire ASNs, make sure they are not classified as "ISP" type. For that, visit our website's ASN page first.
If you have raw logs, you can send them to me as well, and I can review them and provide some guidance.

Same for the origin IP address. The fiber leaving your country is tapped, and those people can inject packets with any origin IP that they want. Your ISP has no way to check if their peer actually received a certain packet from a certain country or not.
From a technical perspective, all this "china/russia" attribution is built on a quite shaky foundation. As a sysadmin you'd never know if it would be the British crown attacking your European company instead.
Not minimizing nation state cyber crime here, but the packet goes through many hands with different incentives.

Very similar experience here. Started July 30, sustained through August 6, when it started a significant ramp-up in volume (5x or so).
Most of the traffic is originating in GCP. We're seeing ~70k req/min sustained from Google Cloud IP space (AS396982). Reported to GCP Abuse, they've been non-responsive so far.
The main distinguishing factor is the reuse of a bunch of legit AI-training bot UserAgent strings. It's clear that the traffic is under the same centralized control because of how it changes volume across thousands of IP addresses simultaneously.

Best hypothesis I can come up with is to somehow make the AI companies look bad, but they seem to be doing an excellent job at that themselves already by scraping everyone hundreds of times per hour over and over.

Because businesses dont want them blocked, that would be a very stupid thing for most of them to do given its becoming a vital traffic source now that people are using chatbots instead of google.

From what I have seen at work, everyone is using chat bots but no one is visiting websites through them. We still get almost all traffic through social media and google search.

Yeah. Do you want the bot to buy the product from your website or your competitors?

the numbers are much smaller than traditional search but they are trending up, and they convert at almost 2x the rate of organic search inbounds. sure you can play catchup later, but the trend is quite clear. if there's one thing the last two years have taught me, my prior heuristics on now vs future don't work in 2026.

Googlebot and other web scrapers are how you get visible, how you get adwords, ways to boost your traffic, etc.
bots hitting your site aren't problems per se

Most websites don't have an incentive to block AI bots to their main sites. Think businesses, government and community websites, nonprofits, etc.
Using a normal page per blog entry would go a long way to making your site more indexable, readable, shareable and seo-able. (Good article btw).

Fake Googlebot visits are #1 in website logs I've been working on. At the beginning I was fighting with them using Cloudflare ASN block rules or their managed Bot Fight mode but it appeared to be not only pointless, but also harmful for my websites.
Bot Fight mode randomly started blocking real Bing / Google / OpenAI crawlers what wasted crawling budget and discouraged crawlers to revisit updated pages.
Sometimes it's better to not fight with bots actively but harden environment and only react for the worst offenders.

For Google it's pretty straight forward to throw away fake crawlers by just only allowing their published list of crawler IPs so you don't accidentally allow someone from a random GCP IP to crawl you if unwanted (https://developers.google.com/crawling/docs/crawlers-fetcher...).

Also Googlebot is an AI training crawler so if you block AI training crawlers you should just block it.

Just in case any of the authors read HN, I'm getting a pretty crazy rendering bug on this page, where a bunch of the contents are redrawing up and down by a few pixels. It seemed to go away with resizing the width a few times, but I didn't look into it too hard. My page width was probably small on first draw. Incredibly distracting though and hard to read with the text moving. Using latest chrome, and it occurred on more than one page refresh. I didn't dig in beyond that though.

I'm seeing the same thing on Firefox on Linux. It almost looks like the page scroll is jiggling up and down a tiny amount constantly when it's supposed to be stationary.

Interesting thought: what if the idea of an open internet is over.
What if we're now moving into a world of strictly KYC. The same way "The Facebook" generated massive revenue by creating a KYC world.

Definitely, the point here though is there is a stat sig surge in the chart in the last week, across thousands of websites. At least a surge in this particular spoofing pattern.

This is a random sample of completely unrelated websites, which indicates that the total scale is much larger. This is not saying that it is difficult to make thousands of requests.

I think this is more of a "if you left your AI tools exposed someone is looking for them" change. Hacking someone else's agents sounds like a great way to spend less on your own tokens.

Nah these are just the typical vuln scans that try all kinda basic shit, looking for anything commonly used AI tools included.
This kind of stuff is getting pretty wild, even for using something like Cloudflare it seems like a good idea to have another layer behind it that's non-cloudflare for when vulnerabilities are discovered.

For my personal website it’s 10x more bots but I barely notice because it’s a few pages.
For the record I thought I had this site behind basic auth.
New hotness: DNS-less
See? It's quite short.
> IMO that's the same as going on the street door by door and checking if one is left open to steal everything inside the house...
From experience: this does happen regularly in some neighborhoods of some cities in the US, and even that isn't always an enforcement priority. So lack of enforcement on the internet, where most the perpetrators probably aren't even in a jurisdiction with an extradition treaty, isn't exactly surprising.
I'm just collecting the data now to be used to secure some of my upcoming projects, but I would absolutely also like to take it in a direction where it sends the bots into an infinite slow loop, or preferably something that burns as many tokens as possible for them.
I don't really care about the morality of that. I'm a big fan of fighting fire with fire.
Not to throw water on your plan, but the bots I've written intentionally run very slow with respect to each target. When done in parallel, across a wide range of targets, it doesn't slow down the effort at all.
Monitoring WAN traffic really gets the paranoia juices flowing.
Just build your website yourself as deep in the stack as you can instead of piling up 50 abstractions on top of each other. Some decisions like having your page be accessible by IP can only happen if you use technology like generic http servers (like apache or nginx) from the 2000s instead of implementing the lower stacks and actually thinking about whether that makes sense for a second.
If when you build a website or a backend, your server responds to requests by IP address (for example), you are building a bottom 90% product, and considering most software markets are super top-heavy, (say 1% win), that's ngmi land.
You'll see a lot of deepfield, censys-scanner, visionheight.com, shadowserver.io, etc., but also the usual suspects of Chinese or Russian IPs.
With OpenWRT I use something like this: `tcpdump -i pppoe-wan 'inbound and tcp[tcpflags] & (tcp-syn|tcp-ack) == tcp-syn'`, or alternatively `tcpdump -i pppoe-wan 'inbound and tcp[tcpflags] & (tcp-syn|tcp-ack) == tcp-syn and not port 44000'`, if we have some torrent client running (e.g. here at port 44000) which would mess up the result. I'm not sure it's the best way to handle this, but it's definitely enlightening what bounces off on the router.
Sure their packets will still hit your router, but if they are dropped immediately at least you're not wasting a syn-ack on them.
Thanks in advance.
Your firewall vendor should supply you with country lists, just select the known bad ones and drop their traffic. If you have a consumer grade router, you will probably have to configure the blocklists manually.
ISPs sometimes do trade IPv4 blocks and countries to which it belongs do change occasionally. That can become a problem if you were like literally Netflix and someone few nation states over started an ISP.
Here is a "simplified" version in various formats.
https://github.com/HotCakeX/Official-IANA-IP-blocks
(You still could get poked from the other users' hosts behind the ISP's NAT, of course.)
https://en.wikipedia.org/wiki/Code_Red_(computer_worm)
I remember when 'code red' spread and it had the effect of crapping up the contents of my apache server logs. Fun times.
such as:
GET /default.ida?NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a HTTP/1.0
We collect signals that help determine good vs bad networks. For example, large amounts of requests to .php endpoints, large amounts of empty accounts from the same /24 subnet, etc etc. All these signals let us automatically determine risk, and then put up a challenge. Authenticated users never see the challenge even if they are on a risky network (VPN 99.9% of the time), unless the network has been identified as 100% malicious, then it gets a full block.
Here's a small snapshot of the dashboard:
https://cos.ridewithgps.com/screenshots/6a7c54d0-12Aug26-358...
This was probably a total of 3-4 days of work, spread out over a couple months of iterative claude led hacking. I didn't know exactly what to build, but had some of the key architectural ideas in my head. Opus+Faable made easy work of it all, and ended up guiding some really slick improvements for performance.
I would say this has dropped about 20% of all traffic to our service, though it turns out turnstile is a massive target for bots, so replacing that with something custom is next on the list.
You know all these guys just switch to residential proxies if they detect a site is blocking data centers, right? Because that's a very common thing to do.

Honeypot dashboard, where you can see attempted attacks in realtime: http://knock-knock.net
API: http://knock-knock.net/api

It never ceases to amaze me that these ISPs don’t bother to shut down the botnets. They could do so very easily. For example, they could identify the IP address of every bot that hit this honeypot with their ASN with one API call: https://api.knock-knock.net/check-asn?asn=<asn number>. (See https://knock-knock.net/api). They just don’t care!
You take IP down, you kill the cancer but you also end up killing the patient.
However, I can see the argument for giving the customer 24-48 hours to resolve the problem.
I'd say its probably an acceptable casualty in the battleground that is the internet especially for little one-off sites hosting blogs, forums, chat servers, etc... For a bigger site I would expect that person may have to open a ticket with the platform such as Amazon accepting that some CDN's and firewalls may be harder to get the block removed. This is why we can't have nice things.
IP Blacklists, no matter how good can't stop this. You have to start using stats or deep-diving telemetry.

So appeal to emotion doesn't fly with me. If grandpa is 76 in the year of our lord 2026 that means he was 50 when the internet was getting popular and 59 when cell phones became very popular on the internet. He's not much older than I. He knows what's up.
God help the makers of that television if he finds out it has been spying on him and dorking around with his traffic. If they are lucky he will just take a baseball bat to it. If they are unlucky he will fly to their headquarters and end up on a viral bodycam video likely with a lot of supporters that will bail him out of jail.
IP Blacklists, no matter how good can't stop this. You have to start using stats or deep-diving telemetry.
I use a myriad of methods including IP blacklists. That's my choice and every site operators choice. I do not have to use deep-diving telemetry but you are free to do so.

> block http 1.1, real users only use 2.0
Chrome on android and Firefox on linux both appear to use 1.1 still...
There are some reader apps that act as a proxy that only support http/1.1. Be careful, some of those are not just readers and do not trust what they claim to be the source code. Some of them are created by cute and fuzzy bunnies.
There are a number of botters on HN, some that control residential and phone browser-hijacked systems. One was sending me playful messages the other day. I enjoyed the bot block-jousting with them.
[1] - https://caniuse.com/http2
No, because legitimate users do not just use residential and "commercial" IPs. Like me, right now
I am going to move full blocking to a test node that people can play with but I have to finish working with Claude to revise someones repo is is no longer maintained because one does not simply put an anonymous chan board on the great wide open internets without some critical thinking.

The complete hysteria people go to over the near-non-issue of bots is, well, completely hysterical. Don't be that guy.
https://github.com/geoacumen/geoacumen-country
If you have fail2ban or NGINX logs, you can use our CLI to summarize those IPs and identify the ASNs you want to block. But before you block entire ASNs, make sure they are not classified as "ISP" type. For that, visit our website's ASN page first.
I have quite a few community posts around this approach. https://community.ipinfo.io/
If you have raw logs, you can send them to me as well, and I can review them and provide some guidance.
From a technical perspective, all this "china/russia" attribution is built on a quite shaky foundation. As a sysadmin you'd never know if it would be the British crown attacking your European company instead.
Not minimizing nation state cyber crime here, but the packet goes through many hands with different incentives.
Most of the traffic is originating in GCP. We're seeing ~70k req/min sustained from Google Cloud IP space (AS396982). Reported to GCP Abuse, they've been non-responsive so far.
The main distinguishing factor is the reuse of a bunch of legit AI-training bot UserAgent strings. It's clear that the traffic is under the same centralized control because of how it changes volume across thousands of IP addresses simultaneously.
Best hypothesis I can come up with is to somehow make the AI companies look bad, but they seem to be doing an excellent job at that themselves already by scraping everyone hundreds of times per hour over and over.

Seems like the crawler companies would be incentivized to not want to take responsibility for people spoofing their user agents.
