When businesses think about cybersecurity, they often focus on protecting website files, preventing malware and blocking suspicious traffic. But there is another asset that can be just as important: the domain name.<\/p>\n
Your domain is the address customers use to find your website and, in many cases, your business email. If an attacker takes control of it, they may be able to redirect visitors, interfere with email delivery or make legitimate online services difficult to access.<\/p>\n
This is known as domain hijacking. It is different from an ordinary website hack because the attacker targets control of the domain registration or its management rather than necessarily modifying the website itself.<\/p>\n
For businesses that rely on their online presence, understanding how domain hijacking happens and how to prevent it is an important part of cybersecurity.<\/p>\n
Domain hijacking occurs when someone gains unauthorised control over a domain name or the account used to manage it.<\/p>\n
A domain is registered through a registrar, and its owner or authorised administrator uses a management account to control settings such as nameservers, DNS records and renewal information.<\/p>\n
If an attacker gains control of that account or manipulates the domain’s registration, they may be able to change where the domain points.<\/p>\n
For example, a customer visiting your usual website address could be redirected to a fraudulent page. Business email may also be affected if the attacker changes the relevant mail-related DNS records.<\/p>\n
Importantly, a domain can be hijacked even when the website’s hosting server has not been compromised. The attacker may redirect visitors without ever gaining access to the website files.<\/p>\n
One possible route is a compromised domain management account.<\/p>\n
An attacker may obtain login details through phishing, password reuse, malware or a compromised email account used for password recovery.<\/p>\n
If the attacker can sign in and make changes, they may be able to alter nameservers, modify DNS records or attempt to transfer the domain.<\/p>\n
Domain administration accounts are often linked to a business email address. If an attacker controls that mailbox, they may be able to intercept verification messages, reset passwords or approve changes.<\/p>\n
This makes email security an important part of domain protection.<\/p>\n
A suspicious change to nameservers or DNS records can redirect website traffic or disrupt email services. Such changes do not always mean the domain has been hijacked, but they deserve investigation if no authorised administrator made them.<\/p>\n
Businesses should know who is permitted to manage their domain and maintain a record of legitimate changes.<\/p>\n
A different but related risk occurs when a domain expires and is not renewed in time. Depending on the registrar’s policies and the domain’s lifecycle, it may eventually become available for registration by someone else.<\/p>\n
An expired domain is not necessarily a hijacked domain, but losing control of a business domain can have similarly serious consequences.<\/p>\n
The impact depends on what the attacker can control.<\/p>\n
Website redirection:<\/strong> Visitors may be sent to a fraudulent website or an unrelated destination.<\/p>\n Email disruption:<\/strong> Changes to MX records or other mail-related DNS settings may prevent legitimate messages from reaching the intended mail service.<\/p>\n Customer fraud:<\/strong> Attackers may use a lookalike destination to impersonate the business or trick customers into submitting information.<\/p>\n Business interruption:<\/strong> Customers may be unable to access the website, online store, booking system or customer portal.<\/p>\n Reputation damage:<\/strong> Even after control is restored, customers may question whether the business’s website and communications can be trusted.<\/p>\n The domain itself may also become involved in disputes or transfer procedures if registration details have been changed without authorisation.<\/p>\n Use a strong, unique password for your domain registrar account. Never reuse the same password across your registrar, email, hosting and other business services.<\/p>\n Enable multi-factor authentication wherever it is available. This adds another layer of protection if a password is exposed.<\/p>\n Review the account’s recovery email address, telephone number and authorised users to make sure they remain under your control.<\/p>\n Ask your registrar which transfer-lock or domain-lock features are available for your domain.<\/p>\n A registrar lock can help prevent unauthorised transfers, although it does not stop every type of account compromise or DNS change.<\/p>\n Some domain extensions have additional registry-level protections or different eligibility requirements. Confirm the available controls with your registrar rather than assuming all domains support identical features.<\/p>\n Your domain management account is only as secure as its recovery process.<\/p>\n Secure the associated email account with a unique password and multi-factor authentication. Review forwarding rules, recovery methods and active sessions for signs of unauthorised access.<\/p>\n If your business email is compromised, an attacker may be able to reset access to other critical services, including domain management and hosting.<\/p>\n Only trusted staff should have permission to make important domain changes.<\/p>\n Avoid sharing a single administrator password among several employees. Where the registrar supports separate users and permissions, use individual accounts and grant only the access each person needs.<\/p>\n Remove access when employees or contractors no longer need it.<\/p>\n Keep a record of your intended DNS configuration, including website records, nameservers and mail-related records.<\/p>\n Periodically check the domain’s current configuration and investigate changes that were not authorised. DNS monitoring services and registrar notifications may help identify unexpected modifications.<\/p>\n Be careful when making legitimate DNS changes. Incorrect records can also cause downtime, so changes should be documented and tested.<\/p>\n Enable automatic renewal where appropriate and make sure the registrar’s payment method and contact details remain valid.<\/p>\n Use reminders as a second safeguard, particularly for domains that support essential business services.<\/p>\n Automatic renewal is not a substitute for account security, but it reduces the risk of accidentally losing a domain because a renewal was missed.<\/p>\n If you discover unexpected nameserver changes, an unfamiliar registrar login or unexplained redirection, act promptly.<\/p>\n First, contact your registrar through its official website or a verified support channel. Explain what you have observed and ask about securing the account, reviewing recent changes and restoring authorised control.<\/p>\n Secure the associated email account and change compromised credentials from a trusted device. Enable multi-factor authentication and review active sessions and authorised users.<\/p>\n Preserve relevant notifications, account activity and DNS records. This information may help establish what changed and when.<\/p>\n Once control has been restored, review the website’s DNS records carefully. Confirm that the website points to the correct hosting destination and that email records match the intended mail service.<\/p>\n Do not make random DNS changes in an attempt to fix the problem. Incorrect changes can create additional disruption, and some updates take time to propagate through DNS caches.<\/p>\n If the attacker also gained access to the hosting account or website itself, investigate those systems separately. Recovering the domain does not automatically mean the website is clean.<\/p>\n Cloudflare provides DNS and website security capabilities, but it is important to understand the limits of those protections.<\/p>\n A reverse proxy and web application firewall can help protect website traffic. They do not, by themselves, guarantee that the domain registration account cannot be compromised.<\/p>\n Domain registrar security, account authentication and transfer protection remain important. The exact controls available depend on where the domain is registered and how its DNS is managed.<\/p>\n Businesses using Cloudflare should also protect the account that manages their Cloudflare configuration. Unauthorised access to that account can create a separate risk even if the registrar account remains secure.<\/p>\nHow to Protect Your Domain Name<\/h2>\n
