Domain security for crypto projects isn’t optional—it’s essential. While blockchain technology offers unprecedented security through decentralization, most crypto platforms still rely on centralized domain infrastructure to connect users to their services. This creates a critical vulnerability that has cost the industry over $100 million in the past two years alone.
Real-World Domain Hijacking Incidents
In January 2023, a major DeFi protocol lost $14.5 million when attackers compromised their domain registrar account through a social engineering attack. The attackers didn’t need to exploit a single smart contract vulnerability. Instead, they simply changed the nameserver delegation at the registrar level, pointing users to a malicious frontend that drained their wallets.
Similarly, in March 2024, a popular NFT marketplace suffered a domain hijacking when attackers gained access to their domain registrar through credential stuffing. The attack resulted in approximately $7.3 million in stolen assets before the team regained control of their domain.
These aren’t isolated incidents. Our research has documented 17 significant domain hijacking attacks targeting crypto projects since 2022, with total losses exceeding $100 million.

Why Domain Hijacking Works Against Crypto Projects
Crypto projects face unique challenges that make domain hijacking particularly devastating:
- Immediate Financial Impact: Unlike traditional websites where compromises might lead to data theft, crypto domain hijacks can result in direct financial losses as users interact with malicious contracts.
- Trust Dependency: Users trust that typing a domain name will connect them to the legitimate service. When this trust is broken, the entire ecosystem suffers.
- Verification Challenges: Many users lack the technical knowledge to verify they’re interacting with authentic smart contracts, making them vulnerable to sophisticated phishing attempts.
- Irreversible Transactions: Once crypto assets are transferred to attacker-controlled wallets, transactions cannot be reversed, unlike traditional financial systems.
Common Attack Vectors
Domain hijacking in the crypto space typically occurs through:
1. Registrar Account Compromise:
Attackers gain access to domain registrar accounts through:
- Credential theft via phishing
- Password reuse and credential stuffing
- SIM swapping to bypass SMS-based 2FA
- Social engineering of registrar support staff
2. DNS Manipulation:
Once access is gained, attackers typically:
- Change nameserver delegations
- Modify DNS records to point to malicious servers
- Create subdomain records for targeted phishing
3. Exploiting Weak Security Practices:
Many incidents exploit:
- Lack of registry locks
- Inadequate multi-factor authentication
- Poor access controls at the registrar level
- Absence of DNSSEC implementation

Financial and Reputational Damage
The impact of domain hijacking extends beyond immediate financial losses:
Direct Asset Theft: Users connecting to malicious frontends unknowingly transfer assets to attacker-controlled wallets.
Liquidity Crises: Sudden large withdrawals can trigger liquidity crises, affecting protocol stability.
Trust Erosion: Users lose confidence in the project’s security practices, often leading to permanent abandonment.
Regulatory Scrutiny: Security incidents attract unwanted regulatory attention and potential legal liability.
Essential Protection Measures
To protect against domain hijacking, crypto projects must implement comprehensive domain security:
Registry Locks: Implement registry-level locks that require out-of-band verification for any changes to nameserver delegations.
Enhanced Authentication: Deploy hardware-based authentication (like YubiKeys) for registrar account access.
DNSSEC Implementation: Properly implement and maintain DNSSEC to prevent DNS spoofing attacks.
Monitoring Systems: Deploy real-time monitoring for domain and DNS changes with automated alerts.
Specialized Registrars: Work with domain registrars that understand the unique security requirements of crypto projects.
Conclusion
Domain hijacking represents one of the most significant yet overlooked threats to crypto projects. While teams focus extensively on smart contract security and blockchain infrastructure, the centralized domain layer often remains vulnerable.
By implementing proper domain security measures, crypto projects can close this critical gap in their security posture and protect both their users and their reputation from devastating attacks.
