Guide to Domain Hijacking - Threat and Prevention Strategies Published: 14 Jun, 2024
Consequently, the malicious act of domain hijacking, where unauthorized individuals gain control of a domain name, poses a serious threat and there is need to understand how to prevent this. And in this article, I will talk about domain hijacking, its threat and how to prevent it.
What is Domain Hijacking?
Domain hijacking occurs when an unauthorized party illegally gains control over a domain name. This unauthorized access typically involves manipulating domain registration information, transferring ownership, or altering DNS settings without the consent of the legitimate owner. The consequences of domain hijacking can be devastating, including loss of business revenue, damage to brand reputation, and compromised sensitive information.

Methods of Domain Hijacking
There are various domain hijacking methods which include:
1. Social Engineering:
Social engineering is a method used in exploiting human psychology rather than technical vulnerabilities. Attackers manipulate domain owners, registrars, or employees into revealing confidential information or performing actions that grant unauthorized access. Phishing emails, fraudulent phone calls, and impersonation are common social engineering tactics.
2. Exploiting Registrar Vulnerabilities:
Domain registrars are entities responsible for managing domain name registrations. Domain Hijackers may exploit security weaknesses in registrar systems, such as weak authentication mechanisms or software vulnerabilities, to gain control over domain accounts which then allow them to take over a domain.
3. DNS Hijacking:
DNS (Domain Name System) hijacking involves redirecting the DNS records of a domain to point to malicious servers. This can be achieved by compromising the registrar's DNS servers or manipulating DNS settings. As a result, users attempting to visit the legitimate website are redirected to malicious sites.

4. Man-in-the-Middle Attacks:
In man-in-the-middle (MitM) attacks, hackers intercept and alter communication between the domain owner and the registrar. By manipulating this communication, attackers can initiate unauthorized domain transfers or make changes to domain settings.
A Notable Case of Domain Hijacking: S e x. com
One of the most infamous cases of domain hijacking involves the domain "S e x. com." This case highlights the severe consequences of domain hijacking and the complexities involved in recovering a hijacked domain.
The Hijacking Incident
In 1995, Stephen Michael Cohen, a notorious cyber-criminal, hijacked the domain Sex.com from its rightful owner, Gary Kremen. Kremen had registered the domain in 1994 with Network Solutions, one of the few domain registrars at the time. Cohen, through a series of fraudulent activities, managed to transfer the ownership of the domain to himself.
Cohen submitted a forged letter to Network Solutions, claiming that Kremen had authorized the transfer of the domain to him. The registrar, failing to verify the authenticity of the letter, processed the transfer, giving Cohen control over the domain. Cohen quickly monetized the domain, generating substantial revenue from adult content and advertisements.
The Legal Battle and Recovery
Gary Kremen, upon discovering the hijacking, initiated legal action to reclaim his domain. The legal battle spanned several years and involved multiple lawsuits. In 2000, a federal court ruled in favor of Kremen, acknowledging that Cohen had illegally obtained the domain through fraudulent means.
Recovering the domain was a complex process. The court ordered Cohen to return the domain to Kremen and pay substantial damages. However, Cohen evaded arrest and refused to comply with the court orders. It was not until 2003 that Kremen finally regained control of Sex.com after Cohen was apprehended in Mexico and extradited to the United States.

Preventing Domain Hijacking
Preventing domain hijacking requires a multi-faceted approach that combines technical measures, best practices, and vigilant monitoring. The following strategies can significantly reduce the risk of domain hijacking:
1. Choose a Reputable Registrar:
Selecting a reputable domain registrar is the first step in securing your domain. Reputable registrars implement robust security measures, such as two-factor authentication (2FA), domain locking, and regular security audits. Research and choose registrars with a proven track record of security and reliability.
Below are the most popular domain registrars where you can buy domain names:
- through Godaddy
- through Namecheap
- through Namesilo
- through hostgator
- through bluehost
- through hostinger
- through OVHcloud US
2. Enable Two-Factor Authentication (2FA):
Two-factor authentication adds an extra layer of security by requiring two forms of verification to access your domain account. This typically involves something you know (password) and something you have (a mobile device). Even if an attacker obtains your password, they would still need the second factor to gain access.
3. Use Strong, Unique Passwords:
Weak or reused passwords are a common entry point for attackers. Use strong, unique passwords for your domain registrar account and change them regularly. Avoid using easily guessable information and consider using a password manager to generate and store complex passwords.

4. Enable Domain Locking:
Domain locking is a security feature that prevents unauthorized domain transfers. When enabled, the domain cannot be transferred to another registrar or account without explicit authorization from the domain owner. This adds an extra layer of protection against unauthorized transfers.

5. Monitor Domain Activity:
Regularly monitoring domain activity can help detect suspicious behavior early. Set up alerts for any changes to domain settings, DNS records, or ownership details. Promptly investigate and address any unauthorized or unusual activities.
6. Keep Contact Information Updated:
Ensure that your contact information, including email addresses and phone numbers, is up-to-date with your registrar. This ensures that you receive important notifications and alerts regarding your domain. Regularly review and update your contact details to avoid missing critical information.
7. Implement DNSSEC:
DNS Security Extensions (DNSSEC) add a layer of security to the DNS by ensuring the authenticity and integrity of DNS responses. DNSSEC helps prevent DNS hijacking by verifying that the DNS records have not been tampered with. Consult your registrar about enabling DNSSEC for your domain.
8. Educate and Train Employees:
Human error is a significant factor in many domain hijacking incidents. Educate and train employees on the risks of domain hijacking and best practices for maintaining domain security. Emphasize the importance of verifying requests and being cautious with sensitive information.

9. Regular Security Audits:
Conduct regular security audits of your domain accounts and registrar settings. Identify and address potential vulnerabilities, and ensure that security best practices are consistently followed. Periodic audits help maintain a strong security posture.
10. Use Domain Privacy Services
Domain privacy services, also known as WHOIS privacy, conceal your personal contact information from the public WHOIS database. This reduces the risk of social engineering attacks by making it harder for attackers to obtain your contact details. Many registrars offer domain privacy services as an add-on.
