The Gell-Mann Amnesia is strong in this story and thead.
As I posted on Krebs' article:
This is neither news nor new. There have been prior panics around this “water is wet” type issue going back at least a decade.
(Search up “Floating Domains – Taking Over 20K DigitalOcean Domains via a Lax Domain Import System” – and others).
I also wrote about this on CircleID from the DNS operator’s perspective (“Nameserver Operators Need the Ability to “Disavow” Domains”) – after this same issue was used to DDoS attack another DNS provider by delegating a domain to their DNS servers without having setup an account there, and then doing a DNS reflection attack on that domain. That was over ten years ago.
The fact that people can delegate their own domains to somebody else’s nameservers without ever properly setting up a zone on those nameservers, or ever keeping track of where THEIR OWN DOMAINS point is 100% the responsibility of the domain owner – and to varying degrees a function of their REGISTRAR – who is the only entity that has any control over it.
It’s a weird flex for corporate registrars who purport to be “high touch” and exclusive, to simply shrug their shoulders and turn a blind eye to their own clients’ obviously broken and vulnerable nameserver delegations.
For our part this is specifically one of things we actively monitor and alert our clients about.
