I’ve actually done this for a Microsoft owned IP before. Someone was Wordpress-scanning a particularly fragile application of one of my clients (which was not Wordpress) which was causing it to fall over. The scan stopped within an hour of sending the abuse email.

Edit to add: I used to work in a NOC for a tier 1 ISP. We had an “abuse department” (a couple people) that investigated these and opened tickets with the NOC. I’ve emailed customers and disconnected circuits as a result of abuse emails, so I wouldn’t say they’re totally useless, but I’m sure it depends on the company involved.

Yea, I have submitted multiple abuse emails with details to domain registrars for scamming and phishing.

Didn’t receive any update from them on any action taken yet.

I’ve done it a couple times. Based on what I’m reading from other users, I guess I got lucky with one, because I got back a personal response thanking me and assuring the abusive whatever was dealt with.

I did try to automate abuse emails via fail2ban, but that ended up getting my entire domain removed because it generated so many emails

I did it in a security incident last year. It took down attacker command and control infrastructure, hindering their operations not just against my company but half a dozen others which had made the news. I found out later about the others on Twitter. After that I became much more positive about the worth of abuse reports.

This video from thiojoe is probably relevant here. It is mostly for scam websites, but maybe it’s useful for this too? At least gives you some platforms to contact

It depends how vindictive I’m feeling and how blatant/annoying the abuse is. In some cases it is easier to just block the IP and move on. When I do I have gotten mixed results. AWS and Google (usually reporting gmail spammers) are usually pretty responsive.

I’ve tried to deal with several vendors regarding abusive domains and it’s pretty terrible in general. Everything is a webform with a generic responder - if any at all - and then weeks or months or nothing. Even domains impersonating proper commercial entities.

• GoDaddy: here’s the real domain, now here’s the domain registered via you, cloned from the real domain (including text, corporate logos, etc with some additional chinese crap) and being used for phishing/scams. Their response: “fill out this bullshit form that goes nowhere”
• CloudFlare: “uh, we don’t actually host the site (just the DNS and “protection” service that hides who does) sorry” Google: “we’ll continue showing the scam/phishing domain in top search results after your reports because apparently accurate search results aren’t actually our thing”

About 20 years ago I was running a phpnuke site on my home server and had someone doing the same thing as you describe. Hundreds of attempts over and over all night long. I went through the logs and saw it was someone on intelsat (I think, it’s been a long time) internet from Africa. I called intelsat or whoever the company was and talked to their system admin that was on call. Within 20 mins of getting off the phone the attack stopped and never happened again. They guy I talked to was really nice and seemed like he was happy to be able to help me.
