What Is Domain Hijacking? How To Prevent It?

Updated April 04, 2024

The article will explore the topic of domain hijacking, a serious cybersecurity threat that can have devastating consequences for businesses and organizations. It will teach you about the various methods attackers use to gain unauthorized access to domain registrar accounts and explain the steps domain owners can take to protect their domain names.

What is Domain Hijacking?

Definition and Effects

Domain hijacking is the act of changing the registration of a domain name without the permission of the original owner. This can be done by gaining unauthorized access to the domain owner's account or by exploiting vulnerabilities in the domain registration system. The effects of domain hijacking can be devastating for businesses, causing financial, reputational, and regulatory damages. Hijackers can use the stolen domain to spread malware, conduct phishing attacks, and gather personal information from unsuspecting users.

Domain Hijacking vs Domain Spoofing

It is important to distinguish between domain hijacking and domain spoofing. While domain hijacking involves making unauthorized changes to the actual domain registration, domain spoofing is the creation of fake websites that closely mimic legitimate ones to deceive users. Both tactics can be used for malicious purposes, but domain hijacking is often more severe as it gives the attacker complete control over the genuine domain.

Types of Domain Hijacking Attacks

There are several types of domain hijacking attacks, including:

  • DNS hijacking: This involves altering the DNS records of a domain to redirect traffic to a malicious website controlled by the attacker.
  • Registrar hijacking: In this type of attack, the hijacker gains unauthorized access to the domain owner's account at the domain registrar, allowing them to make changes to the domain's registration details.
  • Social engineering: Attackers may use social engineering techniques to trick domain owners or registrars into transferring ownership of the domain, often by impersonating the legitimate owner.

Consequences of a Hijacked Domain

The consequences of a hijacked domain can be severe and far-reaching. Some of the potential impacts include:

  • Financial damages: Businesses can suffer significant financial losses due to a hijacked domain, particularly if they rely heavily on their online presence for sales and customer interactions. E-commerce and SaaS companies are especially vulnerable, as the loss of control over their domain can directly impact their revenue streams.
  • Reputational risks: When a domain is hijacked, the original owner may be associated with any criminal activity conducted through the stolen domain, such as distributing malware or engaging in phishing schemes. This can lead to a loss of trust among customers and partners, damaging the company's reputation.
  • Compliance violations: Unauthorized access to a domain can result in sensitive information being accessed or stolen, which may violate data protection regulations such as GDPR. This can lead to hefty fines and legal consequences for the affected business.

How Does Domain Hijacking Work?

Unauthorized Access and Exploitation

Domain hijacking often happens through unauthorized access to a domain registrar or by exploiting weaknesses in the registrar's systems. Attackers may use different tactics to get access to a domain owner's account, such as social engineering, where they trick people into sharing sensitive information or giving access. They may also try to get into the domain owner's email account linked with the registrar and reset the account password, taking control of the domain.

Impersonation and Phishing

Another common way of domain hijacking involves pretending to be the real domain owner. Attackers may collect personal information about the owner through public sources or by using phishing techniques. They then use this information to persuade the domain registrar to change the domain's registration details, moving ownership to the attacker.

Phishing attacks are also often used to steal login credentials for domain management accounts. Attackers may send emails acting as the domain registrar, asking the owner to enter their username and password on a fake login page. Keyloggers and other malware can also be used to get login information when the owner logs into their account.

Reverse Domain Hijacking

Sometimes, real domain owners may falsely say that their domain has been hijacked to get control of a domain from someone else. This tactic, called reverse domain hijacking, is occasionally used in bad faith during domain ownership disputes.

For example, a company may try to claim a domain name that is close to their trademark but owned by another person. By falsely saying that the domain was hijacked, they may try to push the current owner into transferring ownership or seek to have the domain suspended by the registrar.

It is important for domain registrars and dispute resolution providers to carefully look into claims of domain hijacking to stop abuse of the system and make sure that legitimate owners are not wrongly deprived of their domains.

Recovering a Hijacked Domain

Working with Registrars

If your domain has been hijacked, recovering it will largely depend on your registrar's ability to undo the changes made by the attacker. As soon as you notice unauthorized changes to your domain's registration details or DNS settings, contact your registrar and report the incident. Give them evidence of your ownership of the domain and request their help in reversing the hijacking.

If the stolen domain has been transferred to another registrar, ask your original registrar to use ICANN's Registrar Transfer Dispute Resolution Policy (TDRP). This policy helps resolve disputes related to unauthorized domain transfers between registrars. By starting a TDRP dispute, your registrar can work with the new registrar to recover your domain and return it to you.

Steps to Recover a Stolen Domain Name

If your domain has been hijacked, there are several steps you can take to start the recovery process:

  1. Gather evidence: Collect any evidence that proves you are the rightful owner of the domain, such as registration receipts, WHOIS records, and DNS configuration details. This information will be important when working with your registrar or pursuing legal action.

  2. Contact your registrar: Reach out to your domain registrar as soon as possible and report the hijacking. Give them the evidence you have gathered and request their help in recovering your domain. Be persistent and escalate the issue if necessary.

  3. Consider legal action: If your registrar is unable to resolve the issue or if the hijacker has transferred your domain to another registrar, talk to legal counsel to discuss your options for pursuing legal action. They can help you understand the potential costs and risks involved and guide you through the process of filing a lawsuit if needed.

  4. Be prepared for a lengthy process: Recovering a hijacked domain can be a complex and time-consuming process, especially if legal action is required. Be ready for the possibility of a long recovery effort and have a plan in place to minimize the impact on your business during this time.

Throughout the recovery process, stay alert and monitor your domain for any further unauthorized changes. Keep detailed records of all communications with your registrar, legal counsel, and other parties involved in the recovery effort. By being proactive and persistent, you can increase your chances of successfully reclaiming your stolen domain and reducing the damage caused by the hijacking.

Preventing Domain Hijacking

Choosing a Reputable Registrar

One of the most important steps in preventing domain hijacking is to choose a reputable domain registrar that focuses on security. Look for an accredited registrar that offers strong security measures, such as two-factor authentication (2FA) and secure DNS management. These features help protect your domain from unauthorized access and changes.

When selecting a registrar, avoid working with non-accredited or second-hand registrars. These companies may not have the same level of security and could put your domain at risk. Stick with well-known, trusted registrars that have a good history of security and customer support.

Implementing Security Best Practices to Protect Your Domain

To further protect your domain from hijacking, implement the following security best practices:

  • Enable two-factor authentication (2FA) on your domain registrar account and any other accounts related to your domain, such as DNS management or web hosting. 2FA adds an extra layer of security by requiring a second form of verification, such as a code sent to your phone, in addition to your password.
  • Enable domain registry lock, which prevents unauthorized transfers of your domain to another registrar. This feature is often available through your registrar and can be a powerful tool in preventing domain hijacking.
  • Enable account lock, which prevents changes to your domain's registration details without additional verification. This can help stop attackers from updating your contact information or changing your DNS settings.
  • Enable WHOIS protection, which hides your personal contact information from public WHOIS searches. This makes it more difficult for attackers to gather information about you that could be used in social engineering attacks.
  • Use strong, unique passwords for all accounts related to your domain, and change them regularly. If a password is exposed in a data breach on another site, change it immediately to prevent attackers from using it to access your domain accounts.
  • Keep your domain contact details up to date, so that you can be reached if there are any issues with your domain. Outdated contact information can make it difficult to recover a hijacked domain.
  • Never share your registrar account credentials with anyone, even if they claim to be from your registrar or web hosting company. Legitimate companies will never ask for your password.
  • Be cautious of emails requesting login details, as they may be phishing attempts. Always check the sender's email address and hover over links before clicking to make sure they lead to a legitimate site.

Separating Domain Registration and Web Hosting

Another way to reduce the risk of domain hijacking is to use different companies for your domain registration and web hosting. By keeping these services separate, you limit the potential damage if one account is compromised. If an attacker gains access to your web hosting account, they won't be able to change your domain's registration details, and vice versa.

Regular Security Audits

Doing regular security audits of your domain and related accounts can help identify and address vulnerabilities before they can be exploited by attackers. During these audits, review your access controls, security settings, and SSL/TLS configurations to make sure they are up to date and properly configured.

Look for any weak passwords, outdated software, or misconfigurations that could put your domain at risk. By identifying and fixing these issues proactively, you can stay one step ahead of potential domain hijackers.

Enabling WHOIS Protection

WHOIS protection is a service offered by many domain registrars that replaces your personal contact information in the public WHOIS directory with the registrar's own contact details. This helps to reduce the amount of publicly available information that attackers can use for social engineering or other malicious purposes.

By enabling WHOIS protection, you limit the open-source intelligence (OSINT) that malicious actors can gather about you and your organization. This makes it more difficult for them to impersonate you or trick your registrar into transferring your domain.

Implementing DNS Security Extensions (DNSSEC)

DNS Security Extensions (DNSSEC) is a set of protocols that adds an extra layer of security to the Domain Name System (DNS) by digitally signing DNS records. This helps prevent domain spoofing and makes sure that users are directed to the correct website when they enter your domain name.

Implementing DNSSEC requires support from both your domain registrar and your DNS hosting provider. When DNSSEC is enabled, your registrar will digitally sign your domain's DNS records, and your DNS hosting provider will validate these signatures to make sure the integrity of your DNS data.

By using DNSSEC, you can help protect your domain from DNS-based attacks and give your users confidence that they are interacting with your legitimate website.

Educating Employees about Domain Hijacking Risks

Finally, it's important to educate your employees about the risks of domain hijacking and how to prevent it. Train your staff to recognize and report suspicious emails, messages, or phone calls related to your domain or registrar accounts.

Encourage employees to use strong, unique passwords for all domain-related accounts and to enable 2FA or multi-factor authentication (MFA) whenever possible. Establish clear procedures for verifying the legitimacy of any requests to modify domain settings or transfer ownership, and make sure all employees know and follow these procedures.

By involving your entire organization in domain security, you can create a strong defense against domain hijacking and minimize the risk of a successful attack.

Monitoring for Domain Hijacking Threats

Clear and Dark Web Monitoring

Monitoring both the clear and dark web is important for protecting your domain from hijacking threats. On the clear web, regularly check that your WHOIS privacy settings are set up correctly to hide sensitive information like your personal email address, phone number, and physical address. Showing this data publicly can make it easier for attackers to target you with social engineering and impersonation tactics.

It's equally important to monitor the dark web for signs that your domain administrator credentials have been compromised. Attackers often sell or trade stolen login details on underground forums, so proactively scanning these sources can help you detect and reset exposed passwords before they can be used for domain hijacking.

Combining clear and dark web monitoring creates a complete approach to domain security, allowing you to identify and address vulnerabilities across multiple channels.

Detecting a Stolen Domain Name

Early detection is key to minimizing the damage caused by a hijacked domain. One of the most effective ways to spot unauthorized changes is to regularly review your domain's WHOIS records. Look for any changes to the registrant name, email address, or name servers that you don't recognize, as these could indicate that your domain has been stolen.

You should also keep an eye on your website traffic and pay attention to reports from users about strange behavior or redirects. A sudden drop in traffic or an increase in complaints about malware or phishing could be signs that your domain has been hijacked and is being used for malicious purposes.

Using a domain monitoring service can help automate the detection process. These tools continuously scan for changes to your domain's registration, DNS settings, and SSL certificates, and alert you immediately if any suspicious activity is detected.

Importance of Early Detection

The faster you detect a hijacked domain, the quicker you can act to recover it and minimize the potential impact on your business and users. In many cases, the longer a domain remains under the control of an attacker, the more difficult and time-consuming the recovery process becomes.

Implementing proactive monitoring tools and processes is essential for identifying domain hijacking threats as early as possible. This includes:

  • Setting up automated alerts for unauthorized changes to your domain's WHOIS records, DNS settings, and SSL certificates
  • Regularly auditing your domain administrator accounts for signs of compromise, such as logins from unfamiliar IP addresses or devices
  • Training your staff to recognize and report suspicious activity related to your domain, such as phishing emails or social engineering attempts

By detecting domain hijacking attempts early, you can minimize downtime, prevent data breaches, and protect your brand reputation.

Monitoring Domain Expiration

It is also important to monitor your domain expiration date. Hijackers check domain name WHOIS records for domains that are already expired or about to expire soon. Using Uptimia's Domain Expiration Monitoring tool can help you extend your domain on time and prevent others from registering it. You can receive alerts 1 week or a few days before your domain name expires and react on time.

What to Do If Your Domain is Hijacked

Reporting the Stolen Domain

If you find out that your domain has been hijacked, the first step is to contact your domain registrar right away. Report the incident and give any evidence you have to support your claim, such as previous WHOIS records, email correspondence, or screenshots of unauthorized changes. Ask your registrar for help in recovering your stolen domain.

If your registrar does not respond or seems to be involved in the attack, file a complaint with ICANN (Internet Corporation for Assigned Names and Numbers). ICANN has a Uniform Domain Name Dispute Resolution Policy that can help resolve disputes related to domain hijacking and trademark infringement.

Communicating with Stakeholders

When your domain is hijacked, it's important to communicate with your customers, partners, and employees about the situation. Tell them that your domain has been compromised and that they may have problems accessing your website or receiving emails from your domain. Be honest about the potential impacts and risks, such as data breaches or phishing attempts.

As you work to recover your domain, give regular updates to your stakeholders on the progress of your efforts. Share information about the steps you are taking to secure your domain and prevent future incidents. This transparency can help maintain trust and reduce the reputational damage caused by the hijacking.

Post-Recovery Security Measures

After successfully recovering your hijacked domain, it's important to take steps to prevent future attacks. Do a thorough security audit of your domain and related systems to find and fix any vulnerabilities that may have contributed to the hijacking.

Use stronger security controls, such as two-factor authentication, IP access restrictions, and better monitoring, to detect and prevent unauthorized changes to your domain. Review and update your security policies and procedures to make sure they properly address the risks associated with domain hijacking.

Conducting a Post-Incident Analysis

To learn from the domain hijacking incident and improve your security posture, do a full post-incident analysis. Investigate the root cause of the hijacking and identify any vulnerabilities or weaknesses in your systems, processes, or human factors that may have been exploited by the attackers.

Use the findings from your analysis to develop an action plan for fixing the identified weaknesses. This may involve updating your security policies, using new technologies, or providing additional training to your employees. Document the lessons learned from the incident and share them with relevant stakeholders to raise awareness and prevent similar incidents in the future.

Real-World Examples of Domain Hijacking

Case Studies

Domain hijacking has affected many high-profile organizations over the years, showing the importance of strong domain security measures. One notable example is the hijacking of the Google Vietnam domain in 2015. Attackers were able to gain unauthorized access to the domain's DNS settings and redirect traffic to a third-party website. While Google quickly regained control of the domain, the incident demonstrated that even large tech companies are not immune to domain hijacking threats.

Another significant case study is the hijacking of the Lenovo.com domain in 2015. Attackers managed to compromise a Lenovo employee's email account and used it to request unauthorized changes to the company's domain registration. As a result, the domain was transferred to a different registrar, causing disruption to Lenovo's website and email services. This incident highlights the importance of securing not only the domain itself but also the email accounts and other systems used to manage it.

In 2013, the domain of the New York Times was hijacked by the Syrian Electronic Army, a group of hackers supporting the Syrian government. The attackers altered the DNS records of the domain, redirecting visitors to a page displaying their own message. This case study illustrates how domain hijacking can be used as a tool for political or ideological purposes, rather than just financial gain.

These high-profile incidents underscore the severe consequences of domain hijacking, which can include website downtime, email disruption, data breaches, and reputational damage. By examining the tactics used by attackers in these cases, organizations can better understand the vulnerabilities that need to be addressed in their own domain security strategies.

The Role of ICANN in Preventing Domain Hijacking

ICANN (Internet Corporation for Assigned Names and Numbers) plays an important role in maintaining the security and stability of the domain name system. As the global organization responsible for coordinating the management of the DNS root, IP addresses, and other unique identifiers, ICANN has developed various policies and procedures to address domain hijacking and work with registrars and registries to prevent such incidents.

One of the key policies ICANN has implemented to combat domain hijacking is the Registrar Accreditation Agreement (RAA). The RAA sets out the requirements and obligations that registrars must follow to maintain their accreditation with ICANN. These requirements include implementing security measures to protect against unauthorized access to domain management systems, maintaining accurate WHOIS records, and promptly investigating and responding to reports of domain hijacking.

ICANN also works closely with domain registries to make sure they have appropriate security controls in place to prevent unauthorized changes to domain ownership or DNS configuration. Registries are required to implement DNSSEC (Domain Name System Security Extensions) to protect against DNS spoofing and other attacks that could facilitate domain hijacking.

In addition to these policies and agreements, ICANN has launched several initiatives to improve domain security and reduce the incidence of hijacking:

  1. The Expedited Registry Security Request (ERSR) process allows registries to quickly make changes to their systems and processes in response to security threats, such as domain hijacking attempts.

  2. The Registry and Registrar Stakeholder Groups within ICANN provide a platform for these key players to collaborate, share best practices, and develop new policies to address emerging security challenges.

  3. ICANN's Security and Stability Advisory Committee (SSAC) conducts research and provides recommendations on various aspects of the DNS, including measures to prevent and mitigate domain hijacking.

  4. The Centralized Zone Data Service (CZDS) allows authorized users, such as registries and security researchers, to access and analyze DNS zone files. This helps in identifying potential security issues and mitigating threats like domain hijacking.

By continually developing and enforcing policies, fostering collaboration among stakeholders, and promoting the adoption of security best practices, ICANN aims to create a more secure and resilient domain name system that is less vulnerable to hijacking attempts. However, it is important to recognize that domain security is a shared responsibility, and domain registrants, registrars, and registries must all play their part in implementing strong security controls and responding promptly to any incidents that do occur.
