Domain Hijacking: How It Happens and 7 Controls That Prevent It

Domain hijacking is when someone takes control of your domain without permission. They might change your DNS to send visitors to a fake site, read your company email or move the domain to another registrar entirely.

The good news: most hijacks follow a few predictable paths, and a handful of controls block nearly all of them. This guide explains how attacks work, how to spot one and what to do.

The Attack

What Is Domain Hijacking?

Domain hijacking is the unauthorised takeover of a domain name, usually by gaining access to the registrar account, the DNS provider or the email account that controls them. Once in control, an attacker can redirect traffic, intercept email, issue SSL certificates for the domain or transfer it away.

It is different from typosquatting, where attackers register a lookalike domain. In a hijack, they take your real domain.

How Attackers Get In

5 Common Ways Domains Get Hijacked

1. Phishing the registrar login

A fake "renewal" or "verify your account" email leads to a fake login page. This is the most common route.

2. Reused or weak passwords

Passwords leaked in other breaches are tried on registrar accounts. Without MFA, they work.

3. Taking over the contact email

If the domain's admin email is on a free mail account or an expired domain, attackers reset the registrar password through it.

4. Social engineering the registrar

Attackers call support pretending to be the owner, using public details to sound convincing.

5. Expired domains

Not a hack at all. A domain lapses, someone registers it, and now they own your old email and web address.

Spot It Early

Warning Signs Your Domain May Be Hijacked

  • Your website shows content you did not publish
  • Emails stop arriving or bounce
  • You get login, password reset or transfer emails you did not request
  • Nameservers or DNS records changed without a ticket
  • The domain's WHOIS or RDAP details show a different contact
  • Customers report phishing emails from your real domain

Continuous domain monitoring catches most of these within hours.

Prevention

7 Controls That Prevent Domain Hijacking

  1. Turn on MFA for every registrar, DNS and related email account
  2. Use personal logins with roles, never one shared account
  3. Use registrar lock on all domains and registry lock on critical ones. See registrar lock vs registry lock
  4. Use a role email on your own main domain as the domain contact, not a free mailbox
  5. Turn on change alerts for DNS, nameservers and contacts
  6. Auto-renew critical domains for multiple years. See domain renewal services
  7. Publish DMARC at reject so attackers cannot send email as you. See our DMARC setup guide
Act Fast

What to Do If Your Domain Is Hijacked

Step Action Why
1 Contact your registrar's abuse or security team They can freeze the domain
2 Reset passwords and MFA on registrar, DNS and email Cut off the attacker's access
3 Restore DNS records from your backup Bring website and email back
4 If transferred, ask the registrar to reverse it or file a transfer dispute Recover ownership
5 Warn customers about fake emails or sites Limit harm and keep trust
6 Add locks, MFA and monitoring Stop it happening again

Keep proof of ownership ready: invoices, registrar records, company documents and trademark certificates. They speed up recovery.

Real-World Examples

Domain Hijacking Cases

Manufacturer Recovers From a DNS Hijack (Illustrative Example)

Client: Engineering manufacturer, Pune

Challenge: Attackers phished the IT admin's registrar password and changed the MX records, diverting supplier emails for two days.

What we did: Registrar freeze, password and MFA reset, DNS restored from backup, supplier warning issued, registry lock and change alerts added.

Results:

  • Email restored within 6 hours of detection
  • No payment fraud through the diverted mail
  • MFA and alerts now on every domain account

Startup Loses Domain to Expiry, Then Wins It Back (Illustrative Example)

Client: Edtech startup, Hyderabad

Challenge: The founder's card expired, the domain lapsed and a domain reseller registered it.

What we did: Assessed purchase vs dispute options, bought the domain back through a broker, moved to company ownership with auto-renew and backup payment.

Results:

  • Domain recovered in 3 weeks
  • Brand and student email restored
  • Auto-renew and 5-year term on all core domains
Final Thoughts

Make Hijacking Hard and Recovery Easy

Domain hijacking is not rare, but it is preventable. MFA, locks, alerts and auto-renew stop most attacks. A clean record of ownership makes recovery fast if something still goes wrong.
