How does DNS hijacking happen?
Attackers phish registrar logins, exploit weak passwords, or social-engineer support to change nameservers or MX records. Visitors then hit fake sites; email routes through attacker servers. It is devastating and fast.
What registrar hygiene protects your domain?
Enable registrar lock (transfer lock), MFA on the registrar account, and role-based access — not a shared agency password from 2016. Use corporate email for registrar contact, not a personal Gmail that leaves with one staff member.
How does DNS monitoring help?
Alert on nameserver or MX changes. Snapshot DNS monthly and after any project. If your marketing site uses Cloudflare, secure that tenant separately from domain registration credentials.
Why do expiry and recovery planning matter?
Expired domains can be snapped up and repointed maliciously. Turn on auto-renew, keep payment cards current, and know your registrar’s recovery process before an emergency. Pair with DMARC so spoofing is harder even if DNS is attacked.
