How to Prevent Domain Hijacking: A Business Guide

What is domain hijacking?

Domain hijacking is the unauthorized transfer of a domain name from its rightful owner to an attacker. Once an attacker controls your domain, they control your website, your email, and your brand identity.

This is not theoretical. High-profile domains have been hijacked, including major banks, tech companies, and government agencies. The consequences range from website defacement to intercepted email and full-blown data breaches.

How domain hijacking happens

Social engineering the registrar

Attackers contact your domain registrar, impersonate you, and convince support staff to transfer the domain. This is the most common method and exploits weak identity verification at some registrars.

Compromised registrar account

If your registrar login uses a weak password or lacks two-factor authentication, attackers can log in directly and initiate a transfer.

Expired domain sniping

When a domain expires, it eventually becomes available for anyone to register. Attackers monitor expiring domains, especially ones with high SEO authority or active email, and register them immediately.

DNS hijacking

Rather than transferring the domain itself, attackers compromise your DNS settings and point your domain to their servers. This can happen through registrar account compromise or by exploiting vulnerabilities in DNS providers.

Prevention measures

1. Enable registrar lock

Every major registrar supports domain locking (clientTransferProhibited status). When locked, the domain cannot be transferred to another registrar without first unlocking it. Enable this immediately.

2. Use two-factor authentication

Enable 2FA on your registrar account. Use an authenticator app, not SMS. This prevents account compromise even if your password is stolen.

3. Use a reputable registrar

Choose a registrar with strong identity verification procedures, 24/7 support, and a track record of security. Avoid the cheapest option if it means weaker security.

4. Enable auto-renewal

Set your domain to auto-renew and keep payment methods current. This eliminates the risk of accidental expiry.

5. Monitor WHOIS changes

Set up alerts for any changes to your domain's WHOIS record, nameservers, or DNS settings. Unauthorized changes are the first sign of a hijacking attempt.

6. Register common variations

Register common misspellings, different TLDs (.net, .org, .co), and hyphenated versions of your domain. This prevents attackers from registering lookalike domains.

7. Keep contact information current

If your registrar needs to reach you about suspicious activity, they need accurate contact details. Outdated email addresses mean missed security alerts.

What to do if hijacked

1. Contact your registrar immediately with proof of ownership

2. File a complaint with ICANN (for gTLDs) or the relevant ccTLD authority

3. Consider the Uniform Domain-Name Dispute-Resolution Policy (UDRP) process

4. Report to law enforcement if financial loss is involved

5. Notify customers and partners about the compromise
