There is so much spam, abuse, and aggressive scraping that I've had to block:

  - AWS
  - Google Cloud
  - Azure
  - Alibaba Cloud
  - Oracle

and a handful of other ASNs on almost all of my properties. It would be one thing if it was simple scraping, but it's often genuine agentic abuse (just spamming for vulnerabilities* or scraping millions of pages with very little valuable or dynamic content). These clouds must get the abuse happening under their own roof under control.

I banned Alibaba's Cloud two years ago and it still hits one of my domains 1 million times per day, despite every route 4xx-ing during that time.

Even Apple has aggressively ramped up its scraping in the past few months, but thankfully they do respect robots.txt.

It's frustrating because some of my real users route through these clouds via their work VPNs. Also, there are a lot of less-than-reputable AI scrapers using global bot-nets via residential IPs to scrape, making it even harder to detect and ban them without affecting real people.

* like leaked .env routes, brute forcing admin panels, and so on

Application-level banning seems very inefficient, these domains should be banned at the network (IP) level. Just drop any incoming packets from these domains/IPs, send absolutely nothing back that even confirms that you exist.

They are banned at the edge in Cloudflare (now), they never hit my application.

From a domain registry operators point of view Cloudflare are the worst of the bunch by orders of magnitude.

Google DNS are busy but its a hand full of IPs and reasonable. Cloudflare is non-stop never ending traffic. I don't know WTF they are trying to get. I've also seen TCP queries from those same Cloudflare IPs so this is not the result of a DDOS attack on them.

1. Breach router or desktop that hasn't been patched in ages via mass script

2. Establish C&C using cloudflare tunnels

3. Sell these hacked systems as residential proxy endpoints to everybody from state actors to teenagers

4. Some of them will be data scraping services

You are chasing your tail trying to ban by ASN or IP. It may work for another couple of months, at best.

Isn’t scanning for vulnerabilities illegal? Traditionally security researchers had to be very careful about such things

bilekas 6 hours ago

If there's a know CVE in a version of cPanel ir wordpress for example, those platforms broadcast what version they're on, so the matching cve being known is not illegal. You're just correlating known vulnerable versions without doing any probing. Pen testing however, a bit more involved in pulling info out without permission is illegal.

nostrademons 5 hours ago

Can you enforce it? Would you even know who to go after?

Traditionally cybercrimes have been prosecuted by the victim going to their local PD (or the FBI) with the IP address of the offender, and then law enforcement subpoenas the ISP associated with that IP address to figure out the customer associated with that account, and then they have a case for prosecution. It all works as long as cybercriminals are less numerous than law enforcement, fall in the same jurisdiction (or in jurisdictions that have reciprocal extradition treaties), and have a real identity that can be tied to their online activities.

Now, many law enforcement agencies are tied up prosecuting political opponents of their bosses. To the extent that they have bandwidth to investigate and prosecute ordinary crimes, they're going to prioritize the ones that target a.) the government that backs them (of which there are many - you see another headline about the government being hacked every week or so on HN) b.) major corporations that have sophisticated IT systems that can aid prosecution or c.) headlines that will get their boss a PR boost and themselves a promotion. Your personal website does not register among those priorities. You probably can't even prove damages from the intrusion itself. The perpetrator might be a Russian bot that the U.S. doesn't have jurisdiction over, or a Canadian teen that the U.S. previously might've been able to prosecute with reciprocal judicial treaties but now has no leverage over because we've blown up our relationship with Canada. It may be legally a crime, but economically it's not worth prosecution.

Traditionally security researchers had to be very careful because they were doing everything above-board, with their real identity attached to their actions, and they made a very attractive (and PR-worthy) target. Somebody who's port-scanning from Russia through a VPN or residential proxy network is a.) anonymous b.) untraceable c.) out of U.S. jurisdiction and d.) not a headline-worthy target anyway.

A couple years ago I predicted here that a lot of things will break as the U.S. transitions from a high-trust to a low-trust society. This is one of them. Much of our justice system works well when criminals are rare and utterly falls apart when they're ubiquitous.

Does the money add up for that to be a deterrent? Are those using them for general VPN access paying enough that they'd care much, and if so is that enough compared to what they'd lose by kicking off the users abusing external sites (they can't all be using just free plans, and anyway tests to kick them could have enough false positives to lose them good paying customers as well as bad users). In any case is the amount of traffic enough for them to care to spend the effort tracking it to identify the bad users?

Bots and spiders hang onto old URLs longer than I hold onto a grudge.

We had some SSR that followed up with JavaScript listeners to do interactive updates instead of loading a whole new page. But the team responsible didn’t add nofollow and some bots ignore it anyway. Some significant fraction of our cluster size was answering those requests. But one deployment someone broke the fuck out of those links and it showed up immediately in our 4xx error statistics and we rolled the change back within a week.

Three years later I was still seeing those busted URLs being submitted.

Then the fix for the nofollow got implemented and declared done but the flag never got made permanent. We were pretty peeved when someone learned that in some offhand comment in a conversation between teams.

We were already identifying “good” and “bad” bots at the border and telling them to fuck off, so all of this was coming from our supposed friends. And that’s when I realized that a company owning a search engine and a cloud service provider is a protection racket. Google cloud is selling you servers in order to be talked to by Google bots.

Can you do something with fail2ban? I.e. after a small number of requests resulting in 401 or 404, or a series of requests that's too fast to be reasonably from a human, ban that address for 48 hours.

If a legitimate request later comes from that address, it will probably get through.

But not sure how well iptables handles checking every connection against a list of possibly hundreds of thousands of addresses.

trickypr an hour ago

Fail2ban doesn’t work well against residential bot nets. A single ip generally only makes a couple of requests before rotating.

It worked fine... on a small scale But it's one thing to swat flies versus fighting swarm of yellow jackets. Serving a 1MB file a million times a day on a small digitalocean droplet is not feasible. Let's just say it didn't scale. And AI bots usually come with beefier machines, and recover faster after a bomb.

le_curious an hour ago

Why did you serve it from DigitalOcean?

Why not a CDN?

firefoxd an hour ago

It's the content of the page, the raw html, that is replaced with a zipbomb. Example: https://example.com checks if you are a malicious bot, depending on the result, it will send you gzip html or gzipped bomb. So that can't be swapped or redirected to a CDN. The bots would simply ignore the redirect.

kazinator 5 hours ago

Last year, I read your post and implemented it. I had no way to tell whether there is any benefit to it, so I discontinued it. Serving the data, even though it is compressed and the compression is precomputed, was still a waste of bandwidth. It could hit the browsers of legit user (false positive).

The main problem on my site is that bots hit the CGIT repo, where visiting files triggers syntax highlighting scripts.

I put in a skill-testing-question type system where you get a maximally long-lived access cookie if you answer right (so legit users are bothered as infrequently as possible).

I posted a link to an online game I made in the comments here once, and immediately got all kinds of good and bad traffic.

Some people liked my work, found me on LinkedIn and sent a connection with a positive message. Other people tried every which way to SQL inject or attack the site, posted slurs in every available input, etc.

Someone copied the site and hosted their own version with a couple minor changes. I only found that one because they had left one of the links in, which gave me referring traffic from their copy.

All that from one HN comment, very much pre-AI too, not to mention the standard daily slew of requests probing for what I assume are known vulnerabilities in Wordpress or PHP.

The internet is a floodgate of different actors, many of which are automated, and a link posted somewhere like HN opens the valve especially wide.

I want mini games! "Score 5 points" style. Although, it would surely fail ADA compliance. I don't see how any of this could be practically effective, respecting ADA.

dspillett 2 hours ago

If you are rolling your own it probably doesn't need to be as clever as Anubis is trying to be. Simple something relatively CPU heavy in JS will do the trick, bonus points if you can make it memory-heavy too. Most bots will give up running something CPU heavy currently (though they will run a lot of JS stuff as much of the web is inaccessible without) and they aren't going to optimise your challenge in WASM or similar because it isn't worth it for the small number of sites it protects (Anubis' challenges on the other hand may well be worth optimising for that way because of their wider use, hence that project is stuck in the cleverness war of attrition and definitely needs to move toward memory-hard problems and something more efficient than JS sooner rather than later).

My main reason for planning to implement something like that myself instead of something off the shelf is two-fold:

1. The points mentioned above

2. I can be a dick and make some subsets do harder work (longer challenges, adding time delays that wouldn't phase a bot) - “hi there North American IP, I know how much you like extra hassle hence the love of effectively paying for tarriffs, here, have a little extra work on me!”

I'm assuming you're outside the US based on having this idea.

You might as well just say "I'm mad at your country for the tariffs, so here's an extra wait." From the fact you feel the urge to spite people in a tariffing country like this, it's clear the tariffs have had some negative effect on you, which goes against your narrative that they're "effectively paid for" by those in the tariffing country who voted for it.

In server logs you can distinguish the type of LLM's traffic. OAI-SearchBot/GPTBot/ClaudeBot is just indexing but ChatGPT-User/Claude-User etc. may be valuable traffic generated by user's conversation with LLM's. So it's worth choosing which ones you block, instead of blocking all of them.

spindump8930 2 hours ago

Strong agree, a good way forward is letting user agent once again truly mean an agent on behalf of the user. And speaking anecdotally, I've seen different traffic "shapes" under the same UA, which leads me to suspect that some actors might be disguising traffic as more mainstream labs.

In my case this is the main source of registered users. If a user is engaged in a discussion with chatbot and gets the recommendation from it his engagement is higher.

dspillett an hour ago

One option to reduce it, though this is work to setup initially:

1. Use a catch-all subdomain

2. Reject email to addresses where a simple checksum does not match (valid addresses being something like [email protected] where the klmn is taken from hash of asdfghij and some secret, anything not matching that pattern gets rejected) [this means running your own mail server so you can do that on incoming mail, running a scan to pick out and remove errant messages regularly, or having a mail client where you can implement this as a plugin]

3. On your contact detail page, don't give out a straight email address but have the the page run some Anubis style JS before asking the server to respond with an address that works

4. Once an address is obviously being used in a manner you don't care to respond to, add it to an explicit block list.

For extra protection from addresses being passed around (intentionally or via hack & other leaks), ask for their email address first and use that as part of the hash, then you can reject mail to your catch-all that doesn't come from the original other party.

Whether all this is worth the effort of implementing, is of course up to you. It probably isn't… I've been considering something like it, but mainly as a fun little project rather than something that would be massively useful.

Turnstile is maybe effective against simple bots that just try to call curl/requests/whatever but if you have bots that use a browser driver it's completely useless.

Turnstile is no longer effective. Anyone with a budget uses a real headless chrome instance and gets around it. You only need the spendy chrome instances to get the initial cookie, then you pass that to your workers and they scrape.

It’s really starting to suck. The worst part is these are coming from consumer vpn providers that we can’t just block (lots of real users paying real money on our service are vpn users) or they come from big residential isps. The whole residential relay thing is a hard adversary, since it’s spread across so many real users paying ips that you can’t whackamole it. I’d say 1% of residential ips are participating in a botnet (there’s prob some real numbers out there if I cared to look).

This is just going to push everyone harder into walled gardens. Web input biggest inbound but our content is our mote, we are going to have to turn off non logged in content viewing, which will have real business impacts.

That's a vague and borderline off-topic suggestion, imo. When the problem is too many malicious visitors hammering your server, the amount of time it takes the visitors' browser to run the JavaScript is not the issue; on the contrary, when dealing with this issue, you might as well do more rendering client-side to offload as much work from the server side as possible (hence the Anubis-esque defense of adding random JavaScript work that isn't even necessary to render the real page).

robotmay 3 hours ago

I've been posting about this recently but I continue to be bad at either timing my submissions or titling them. I struggle with YouTube thumbnails too so I think it might be me. But anyway:

I experienced the same thing after submitting articles from my small photography website. I did debate using some of the off-the-shelf solutions like Cloudflare, Anubis, or iocaine, but I ended up building my own L7 proxy that utterly fucks the bots up: https://robertmay.photography/journal/bwbach-my-guardian-gob.... I will make it generally available at some point once I get it optimised how I'd like, but currently I'm able to trap about 3000 concurrent crawlers in my tarpit of slow requests on two small Hetzner VMs. And that 3k is really just the limits of the networks hitting my servers right now, I think it'll go significantly higher than that.

I haven't really seen anyone else combat them this way, possibly because many of the standard proxies and servers are set up for fast requests, not serving them as slowly as possible. Deliberately serving page loads for as long as the requester will accept packets turns out to be a really funny way to stop the botnets - when I just rejected the requests they in turn hammered my server even harder. By tanking the request volume with a ridiculous BEAM-based proxy you can reduce their request speed to a crawl and I'm fairly certain a couple of them have blacklisted my server now.

bayganyo 3 hours ago

I like the spirit of this approach; make them suffer! But I'm surprised the bots wouldn't have reasonable timeouts to counteract. How long do they typically wait on these requests?

EDIT: sorry, that was a dumb question before reading your post. You actually learn the timeout they tolerate. Nice!

robotmay 3 hours ago

I should probably put together some actual stats at some point, but from what I see in the live logs you'd be shocked - some of them will happily sit there for over 5 minutes being drip-fed packets!

Looking at you, Meta.

I do still get some requests going up to 15 minutes which is quite ridiculous, though those don't seem to be super common (maybe they're learning).

I think the shortest timeouts I've seen are between 2-5 seconds, but they're surprisingly infrequent and actually that's still a massive inconvenience for them. I did at one point just drop any request I couldn't keep open for more than 5 seconds but it actually caused more server load. I'm essentially inverting the server load by making slow requests more efficient, which is counter to everything I ever learnt about performance for web serving :D

I think the average I see is probably somewhere between 15-30 seconds. I'm guessing many crawlers don't want to go too low because they'll be trying to fetch large files like images, or perhaps they know they'll be slowing servers down and want to ensure they get the response. Most likely, the majority of crawler authors aren't expecting some arsehole to exploit this and they've just left the setting as the default.

Possibly, possibly not. I think some people are used to passing around news/information as short-form videos these days but HN (mostly) isn't into that kind of content.
