What Is Domain Hijacking?
Domain hijacking happens when attackers steal complete control of your domain name by breaking into your registrar account. Think of your domain like owning a house. Domain hijacking means someone forges your signature, transfers the deed into their name, and legally claims ownership of your property. You lose access to everything connected to that domain.
Hackers change your contact information, email addresses, and DNS settings once they control your registrar account. They can redirect your entire website anywhere they want, intercept all your emails, or even sell your domain to someone else.
The original owner gets locked out completely until they can prove ownership and fight to get their domain back through legal processes.
What Is DNS Poisoning?
DNS poisoning corrupts the system that translates domain names into IP addresses without actually stealing your domain. Attackers inject false information into DNS servers that direct internet traffic. When someone types your website address, the poisoned DNS server sends them to a fake site instead of your real one.
This attack works like switching road signs on a highway. You still own your destination, but the signs now point travelers to the wrong location. Visitors think they’re reaching your legitimate website when they’re actually landing on a criminal’s fake copy.
DNS poisoning targets the infrastructure that helps people find your site rather than stealing the site itself.
How Domain Hijacking Actually Works
Cybercriminals usually gain access to your domain registrar account through phishing attacks. They send fake emails that look exactly like messages from your registrar. These emails contain urgent warnings about account problems or domain expiration. The panic-inducing message includes a link to what appears to be your registrar’s login page.
When you enter your username and password on this fake site, hackers immediately capture your credentials. Within minutes, they log into your real registrar account, change all contact information to theirs, and lock you out.
Some attackers use social engineering instead, calling your registrar while pretending to be you. They know enough personal details from public records to convince customer support staff to reset your password or transfer your domain.
How DNS Poisoning Actually Works
DNS poisoning targets the servers that store DNS information rather than your registrar account. Attackers exploit vulnerabilities in DNS software or flood servers with fake responses. They inject malicious data that replaces legitimate IP addresses with addresses pointing to their controlled servers.
The poisoned information gets stored in the DNS server’s cache. Every person who queries that server for your domain receives the corrupted information. Users get redirected to fake websites that look identical to yours. These fraudulent sites collect login credentials, credit card numbers, and personal information from unsuspecting visitors who believe they’re using your real service.
Domain Hijacking vs DNS Poisoning: the Difference and How to Stay Protected
Domain hijacking directly affects domain owners by stealing ownership at the registrar level. DNS poisoning primarily targets users trying to visit domains without changing actual ownership. Hijacked domains often go completely offline or get replaced with totally different content. Poisoned DNS servers redirect some visitors while others still reach the legitimate site.
Recovering from domain hijacking takes weeks or months because you must prove ownership through legal processes. Fixing DNS poisoning happens faster since you still own your domain and can work with DNS providers to flush corrupted cache data. Domain hijacking requires attackers to breach your specific registrar account.
DNS poisoning exploits vulnerabilities in public DNS infrastructure affecting multiple domains simultaneously. Learn more about protecting your domain in our article on 10 ways to protect your domain name from hackers.
Who Gets Targeted by Domain Hijacking?
Valuable domains with established traffic and reputation make prime hijacking targets. Online stores processing thousands of daily transactions attract criminals wanting to steal customer payment information. Popular blogs and content sites with strong domain authority become targets because hijackers can redirect that traffic to their own sites.
Small businesses often face hijacking attempts because attackers assume they have weaker security than large corporations. Companies using their domain for critical email communication become targets since hijacking intercepts all business correspondence. Anyone neglecting basic security measures like two-factor authentication risks becoming a hijacking victim.
Who Gets Targeted by DNS Poisoning?
DNS poisoning attacks target entire DNS server infrastructures rather than individual domain owners. Attackers poison public DNS resolvers used by millions of people. Financial institutions become frequent targets because poisoned DNS servers can redirect customers to fake banking sites that harvest login credentials.
Government websites face DNS poisoning risks during politically sensitive periods. Criminals use poisoned DNS to spread malware by redirecting visitors from legitimate software download sites to infected versions. Any popular website with high traffic becomes attractive because poisoned DNS affects more potential victims.
Real-World Examples of Both Attacks
Major corporations have experienced domain hijacking despite massive security budgets. A brief 2015 hijacking affected Lenovo’s website and redirected Vietnamese Google searches. These incidents prove that even tech giants face domain security threats when attackers find vulnerabilities.
DNS poisoning campaigns have targeted thousands of domains simultaneously. The SubdoMailing attack exploited trusted company subdomains to run fraudulent advertising. Sitting Ducks attacks compromised over seventy thousand domains through DNS configuration weaknesses. These large-scale poisoning operations show how attackers exploit DNS infrastructure to affect many targets at once.
Why Domain Hijacking Is Often More Devastating
Losing domain ownership means losing everything connected to that domain instantly. Your website disappears completely or shows content controlled by criminals. All email addresses using your domain stop working, cutting off customer communication and internal business correspondence. Years of search engine optimization and brand recognition vanish when someone else controls your domain.
Recovering hijacked domains involves expensive legal battles and lengthy ICANN dispute processes. Many businesses never fully recover their reputation after hijacking incidents damage customer trust. The financial losses from downtime, lost sales, and recovery efforts often total hundreds of thousands of dollars. Domain hijacking can literally destroy small businesses overnight.
Why DNS Poisoning Creates Widespread Damage
DNS poisoning affects everyone trying to visit your site, not just you as the owner. Thousands of customers might reach fake sites while you remain completely unaware. Victims who enter sensitive information on poisoned sites suffer identity theft and financial losses. Your brand reputation crashes when customers believe your legitimate site infected their computers with malware.
Unlike hijacking where your site goes offline, poisoned DNS keeps your real site running while secretly redirecting traffic. This makes detection much harder since you don’t immediately notice problems.
By the time someone discovers the poisoning, criminals may have already stolen data from hundreds of victims. Your business faces lawsuits from affected customers even though attackers caused the breach.

8 Ways to Prevent Domain Hijacking
Enable Two-Factor Authentication Immediately
Two-factor authentication requires both your password and a code from your phone to access accounts. Even if hackers steal your password through phishing, they cannot log in without the second authentication factor. Enable two-factor authentication on your domain registrar, email accounts, and hosting accounts.
Most registrars offer authentication through text messages, authenticator apps, or hardware security keys. Authenticator apps like Google Authenticator provide stronger security than text messages. Hardware keys offer the highest protection level but cost more money upfront.
Use Strong Unique Passwords Everywhere
Create passwords with at least fifteen characters mixing uppercase letters, lowercase letters, numbers, and special symbols. Never reuse passwords across different accounts. If one site suffers a data breach exposing your password, criminals immediately try that password on domain registrar accounts.
Password managers generate random complex passwords and store them securely. You only remember one master password while the manager handles everything else. This makes using unique passwords for every account practical and convenient.
Lock Your Domain at the Registry Level
Registry locks prevent any changes to your domain settings without manual verification from your registrar. Transfers, DNS modifications, and contact changes require direct communication with customer support. Even if attackers breach your account, they cannot hijack your domain without your explicit approval.
Most registrars offer registry locks for free or small annual fees. The verification process adds extra steps when you legitimately need changes, but this inconvenience provides massive security benefits. Contact your registrar to enable registry lock today.
Monitor Your Domain Activity Weekly
Check your domain settings every week for unauthorized changes. Review WHOIS information, DNS records, and registrar account activity logs. Set up email alerts through your registrar to receive instant notifications when anyone modifies domain settings.
Early detection stops hijacking attempts before attackers complete the theft. If you notice suspicious changes you didn’t make, contact your registrar immediately. Quick action often prevents full domain loss.
7 Ways to Prevent DNS Poisoning
Use DNSSEC Protection
DNSSEC adds digital signatures to DNS records that verify authenticity. DNS resolvers check these signatures before accepting DNS information. Poisoned data without valid signatures gets rejected automatically. DNSSEC creates a chain of trust from your domain back to root DNS servers.
Enabling DNSSEC requires support from both your domain registrar and DNS hosting provider. Most major registrars now offer DNSSEC features. The setup process takes only a few minutes but provides significant protection against DNS poisoning attacks. For a deeper look at domain security, read what is domain protection.
Keep DNS Software Updated
Outdated DNS server software contains known vulnerabilities that attackers exploit. Regular updates patch these security holes before criminals can use them. If you manage your own DNS servers, apply security updates immediately when released.
Most website owners use DNS services from their hosting provider or registrar. These companies handle updates automatically. Confirm your provider maintains current software versions and follows security best practices.
Use Encrypted DNS Queries
DNS over HTTPS and DNS over TLS encrypt DNS queries between users and DNS servers. Encryption prevents attackers from intercepting and modifying DNS requests in transit. Many modern web browsers now support encrypted DNS by default.
Organizations can configure their networks to use encrypted DNS protocols. This protects all devices on the network from DNS interception attacks. Public DNS services like Google Public DNS and Cloudflare DNS support encrypted queries.
Monitor DNS Records for Changes
Regularly verify that your DNS records point to correct IP addresses. Use DNS monitoring services that alert you when records change unexpectedly. These services query your DNS information from multiple locations worldwide and compare results.
Detecting poisoned DNS quickly limits damage to your visitors and reputation. Some monitoring services automatically notify you within minutes of detecting discrepancies. This rapid response helps you contact DNS providers to flush corrupted cache data immediately.
Combining Protection Strategies for Maximum Security
Neither domain hijacking nor DNS poisoning attacks succeed easily against properly secured domains. Implementing multiple layers of security creates defense in depth that stops most attack attempts. Strong passwords and two-factor authentication prevent account breaches. Registry locks stop hijacking even if accounts get compromised.
DNSSEC prevents DNS poisoning by verifying record authenticity. Regular monitoring detects attacks early before major damage occurs. Domain privacy protection reduces information available for social engineering attacks. Together, these strategies provide comprehensive protection against both threat types. Also explore our guide on how domain name privacy works.
What to Do If You Suspect an Attack
Contact your domain registrar immediately if you notice suspicious account activity or cannot access your registrar account. Provide proof of ownership through old registration emails, payment receipts, or business documents. Most registrars can reverse unauthorized changes quickly if caught early.
For DNS poisoning, contact your DNS hosting provider to flush corrupted cache data. Test your domain from multiple locations using different DNS resolvers to identify poisoning scope. Warn customers through social media and other channels about potential fake sites. File reports with cybercrime authorities and your registrar’s abuse department.
Legal Recovery Options After Attacks
Domain hijacking victims can pursue recovery through ICANN’s Uniform Domain Dispute Resolution Policy. This process requires proving you owned the domain and someone stole it through unauthorized access. Providing documentation like registration emails and payment records strengthens your case.
Some victims file lawsuits in federal courts to recover stolen domains. Legal action works best for high-value domains worth the attorney fees and time investment. Domain lawyers specialize in these cases and handle many recoveries nationwide. Consult with legal experts quickly after discovering hijacking to preserve evidence and meet filing deadlines.

How Both Attacks Affect Email Services
Domain hijacking gives attackers complete control over all email addresses using your domain. They intercept every message sent to your addresses. Criminals use this access to reset passwords for online accounts, impersonate you to customers, or steal sensitive business information. Your team cannot send or receive emails until you recover the domain.
DNS poisoning redirects email traffic by corrupting MX records that specify mail servers. Attackers receive copies of all emails while your real mail server might still function. This creates a man-in-the-middle situation where criminals spy on all correspondence without either party knowing. Encrypted email helps but doesn’t prevent the initial redirect.
The Role of Domain Parking in Security
Unused domains need protection too. Parked domains often have minimal security because owners think nobody targets inactive sites. Criminals hijack parked domains to use them for spam campaigns or malware distribution. Your brand suffers when people see your domain associated with illegal activities.
Properly securing parked domains follows the same rules as active sites. Enable two-factor authentication, use registry locks, and monitor for unauthorized changes. Consider using your registrar’s parking service which typically includes basic security protections. Learn more in our article about what are parked domains.
Understanding Subdomain Vulnerabilities
Subdomains face similar risks from both hijacking and poisoning attacks. If attackers hijack your main domain, they control all subdomains automatically. DNS poisoning can target specific subdomains without affecting your main domain. Organizations often neglect subdomain security because they focus protection efforts on primary domains.
Apply the same security measures to subdomains as your main domain. Monitor subdomain DNS records for unauthorized changes. Large organizations with hundreds of subdomains should maintain detailed inventories. Abandoned subdomains need removal or proper securing to prevent exploitation in attacks like SubdoMailing.
How Multiple Domains Complicate Security
Managing security across multiple domains requires organization and consistency. Many businesses own several domain names for different brands, products, or geographic markets. Each domain needs identical security protections regardless of traffic levels or importance. Attackers often target less-protected domains as stepping stones to more valuable properties.
Create a spreadsheet tracking all your domains, their registrars, security settings, and renewal dates. Schedule monthly audits to verify protections remain active on every domain. Consider consolidating all domains with one reputable registrar for easier management. Some registrars offer bulk discounts and centralized security controls for multiple domains. For details on hosting multiple properties, see how many domains can you host on Bluehost.
The Importance of Choosing Secure Registrars
Not all domain registrars provide equal security features or support. Research registrars carefully before transferring valuable domains. Look for companies offering two-factor authentication, registry locks, DNSSEC support, and responsive customer service. Read reviews from other customers about their security experiences and incident response.
Premium registrars like MarkMonitor specialize in protecting high-value domains for major corporations. Bluehost provides excellent security features alongside their hosting services. Cloudflare Registrar benefits from their cybersecurity expertise and global infrastructure. Cheap registrars that compete only on price often cut corners on security that could cost you everything.
Training Your Team About These Threats
Employees need education about domain hijacking and DNS poisoning to recognize attacks. Many successful hijackings start with phishing emails that trick staff members into revealing credentials. Regular security training helps everyone identify suspicious messages and verify requests through separate communication channels.
Create clear procedures for domain-related requests. Require confirmation through phone calls before approving domain transfers, DNS changes, or password resets. Never approve these actions based solely on email requests. These simple policies stop many social engineering attacks before they succeed.
Historical Context and Evolution of Attacks
Domain hijacking and DNS poisoning have evolved significantly since the internet’s early days. Early attacks used simple techniques against systems with minimal security. Modern attacks employ sophisticated methods exploiting human psychology and complex technical vulnerabilities. The value of established domains has increased dramatically as online business grows.
Attackers now use artificial intelligence to create convincing phishing messages. They research targets thoroughly using social media and public records. DNS poisoning has become more difficult as DNSSEC adoption increases, but attackers adapt by finding new vulnerabilities. The arms race between security professionals and criminals continues accelerating. For historical perspective, read about the history of domain names.
Future Trends in Domain Security
Emerging technologies promise better protection but also create new attack vectors. Blockchain-based domain systems aim to eliminate central points of failure that current registrars represent. However, these systems remain experimental and face adoption challenges. Artificial intelligence helps detect attacks faster but criminals also use AI to improve their techniques.
Quantum computing threatens current encryption methods including DNSSEC signatures. Security experts develop quantum-resistant cryptography to future-proof DNS security. Regulations like GDPR affect domain privacy by limiting personal information in WHOIS records. These privacy protections help individuals but complicate domain ownership verification during hijacking recovery.
The True Cost of Security Versus Recovery
Implementing comprehensive domain security costs between fifty and two hundred dollars yearly for most domains. This includes domain privacy protection, registry locks, monitoring services, and premium registrar features. Recovery from domain hijacking often exceeds ten thousand dollars in legal fees, lost revenue, and damage control.
DNS poisoning recovery involves forensic analysis, customer notification, and reputation repair costing thousands more. The time invested in recovery diverts resources from productive business activities for weeks or months. Prevention costs a tiny fraction of recovery expenses while providing peace of mind and continuous protection.
