This is a perfect example for one of a positive effects of the GDPR afforded to natural persons.
I haven't been associated with that domain for 15 years or so. Why is someone still maintaining my personal data, some of it now wrong/obsolete, in a public database?
Edit: Just to be clear, I don't see a problem with the parent having posted this information here, as the parent just reposted this from another public source. The problem here is clearly the other source.
• tries to visit ckastner.com
• the website is down
• retrieve the information from an archived snapshot instead https://addons.mozilla.org/firefox/addon/resurrect-pages-isu...
• Christian Kastner was already notified by email from his automated monitoring that the website is down
Not everyone with a website is a web developer, or paid a knowledgeable and modern web developer to make the website.
Of course nobody _else_ should be forced on sharing details just for this kind of occasional utility, I'm not claiming that.
Honestly, I think you should take social engineering more seriously if you think the benefits outweigh the costs.
Like someone removing their front door because it might encourage someone to drop by for some stimulating conversation.
For example, the author of the "Amazon Backdoor" post a while back suspected that the attacker got their address from a whois of one of their domains.
I think rather the comments in support of an open Whois are looking at the past with overwhelming nostalgia instead of objective reality.
To your own point, the Web is a very different place now. But Whois is still the same, reflecting a reality that no longer exists. It's time for a change.
We would have preferred someone called us immediately, in case we didn't see the ticket immediately. But we didn't have a security hotline publicly listed.
Putting a phone number in a big public directory of phone numbers for when e-mail doesn't work isn't a bad idea, regardless of what anyone (including the EU) says. We've had phone books forever. This is just a phone book for domains.
"My website is so critical that I want random people to be able to call me about it" is an oxymoron I don't think anybody has ever said.
