Yes but it’s not cheap. Maxmind and ipinfo etc sell a tier that tells you this information, then you can 403 based on it. But the price is nuts like $40,000 a year.

You don't need to spend anywhere near $40k a year to get that info... You don't even need to spend $1

What's your strategy?

Every server with port 80/443 open has thousands of hits a day from random boxes looking for wordpress login pages. The only new thing is that they're pretending to be a different type of annoying bot. There's a new layer of sophistication and subterfuge, but it's the same junk traffic we've always dealt with.

Think about how many webmaster and business owners' egos are stroked by all the traffic they are getting, when in actuality they are often just serving thousands of bots.

I was insulted recently reading about the apparently thousands of hits per second the rest of you guys are getting. Even the bots are shunning me!

Not asking for trust, just sharing the data/math

You forgot the "Yes, that's my company" part in your reply ( https://ghking.co )

That doesn't change the data/math brother

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 OpenW…

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.

I, temporarly, banned some ip range. I didn't find a source for pinpointing countries; though I am interested. Could you point me to some sources which, deterministically, resolve to some countries? To my knowledge you can not reliably identify countries by ip since this would be dependent on DNS servers. Though I am just a application programmer!

Thanks in advance.

I don't even have a domain name and I'm getting lots of hits.

It's still good etiquette to disclose affiliation in online discussions.

Is there an easy way to block any requests originating from VPS etc instead of residential/commercial IP from legitimate users ? I know cloudflare does a few things but I really want to figure out a way to block any request say at nginx or caddy (reverse proxy) from reaching origin servers if they are not from an IP that is not a VPS etc.

Yes but it’s not cheap. Maxmind and ipinfo etc sell a tier that tells you this information, then you can 403 based on it. But the price is nuts like $40,000 a year.

Focsec.com IP database for offline use (datacenters, VPNs, proxies, bots) runs around $1k/month for internal-only use.

People or their agents must be accidentally committing or publishing their repository level secrets and configs with enough regularity that it’s worth scanning.

Totally. I'm sure this campaign was inspired by sloppy vibe coding
