> it has received ~8,000 requests from two of your scanning hosts If it were 8000 requests per second , this might be worthy of some investigation. But 8000 ntp requests alone consume far less than 1 us cent of compute + bandwidth. This isn't worth lifting a finger over.
Please read the article, it's not the volume of the NTP requests, they're actively sending exploit/attempt to compromise payloads. They're probing things in a way that you would ordinarily only do to your own internal infrastructure. "They tried all kinds of exploits against me: path traversal, webshell uploads, probing software internals, probing WordPress and other CMS management endpoints, SSRF, Log4Shell, and a l…

#22CNAME'ing pool-ntp.tesla.com to something they do not control is already quite risky as it would allow someone to e.g. request pool-ntp.tesla.com certificate though it might take quite a few tries.

If you host a webserver on the internet it is normal to receive that kind of traffic all the time. Source: I host a server on my Comcast connection.

#24> They tried all kinds of exploits against me ... probing WordPress and other CMS management endpoints This is standard bot crawler traffic. Anyone who runs a home server sees attempts to load wp paths all the time

#25I’m pretty sure this way they’ve hardcoded the NTPs is actually against the ToS for use of the NTP pool too. The way a vendor embedding NTP is _meant_ to do so is documented here: https://www.ntppool.org/en/vendors.html On another note, back when I ran a web hosting business we hosted a few NTP servers in the pool. It’s such a simple thing to give back, and worth anyone who can make a stable contribution doing so.
Note that in the past I've had companies writing embedded linux based firmware using ntppool for time sync request their own vendor zones, however a lot of those requests were ignored so it's unclear if that's still expected. In the end they ended up just using the default ntppool domains since they never got their own vendor zones.

#26This happens EVERY day to EVERY web server out there. I have a personal site that gets thousands of requests per day from bots.
Running a public server (like NTP) means you will get tons of strange requests. Moreso if you run a web server on the same IP because bots will scrape certificate transparency logs. The entire IPv4 space is scanned continuously.
This may sound harsh, but you cannot stop it. It is whack-a-mole. Filter it and move on, go outside and touch grass, seriously. This is not worth being upset over.
I treat these as an opportunity to tune my filters and firewall rules.

I thought about trying this, but MPIC makes it very very very difficult (the round-robin has some geolocation magic baked in regarding what server it connects you to).

I don't go complaining on the internet about the absolute shitflood of compromised routers on broadband ISPs in Indonesia probing my stuff 24x7x365 because I know it would be futile. But if I found one specific american company that was repeatedly probing my stuff all the time? Maybe I'd escalate it.
