Domain hijacking: what IAM teams need to tighten now

TL;DR: Domain hijacking works when attackers combine registrar details, administrative email access, and login credentials to transfer ownership and disrupt services, according to DigiCert. The deeper lesson is that identity controls around domains fail when email security, patching, and registrar authentication are treated as separate problems.

NHIMG editorial — based on content published by DigiCert: The Consequences of Domain Hijacking

By the numbers:

• 37% of vulnerabilities in hosting web servers could have been prevented by applying security patches as soon as possible.

Questions worth separating out

Q: How should organisations protect domains from hijacking attempts?

A: Treat domain administration as privileged access, not routine web management.

Q: Why do phishing and server vulnerabilities matter to domain security?

A: They are the most common ways attackers collect the registrar name, administrative email, and login credentials needed for takeover.

Q: What breaks when registrar authentication is weak?

A: Weak registrar authentication turns a stolen password or compromised inbox into full ownership transfer risk.

Practitioner guidance

• Harden registrar access as privileged identity Require phishing-resistant authentication, tight password policy, and explicit approval checks for any domain transfer or recovery request.
• Reduce credential exposure paths Prioritise patching for web servers, because exposed vulnerabilities can reveal the same credentials attackers need for registrar takeover.
• Separate domain recovery from everyday administration Create a documented recovery process that verifies transfer requests out of band and requires more than inbox access alone.
