Recent Security Incidents and Responses
On May 12, 2025, Curve Finance experienced a significant security incident when its domain registrar, “iwantmyname,” was compromised. This breach led to a DNS hijack of the “curve.fi” domain, redirecting users to a malicious website designed to mimic Curve’s interface and steal wallet credentials.
The attackers gained unauthorized access to Curve’s registrar account and altered the DNS records, causing traffic intended for “curve.fi” to be rerouted to a fraudulent site. This clone site contained malicious scripts that prompted users to approve transactions, effectively draining their wallets. The malicious site remained active for several hours before being taken down.
This incident was particularly concerning as it was the second attack on Curve’s infrastructure within a week. Earlier, on May 5, Curve’s official X (formerly Twitter) account was compromised, though no user funds were affected in that breach.
Upon discovering the DNS hijack at 21:20 UTC on May 12, Curve Finance took swift action:
- Domain Redirection: The team redirected the compromised “curve.fi” domain to neutral nameservers, effectively taking the malicious site offline.
- New Domain Launch: A new, secure domain, “curve.finance,” was launched as the official frontend for the protocol.
- User Notifications: Users were promptly informed through official channels, advising them to avoid interacting with the compromised domain and to revoke any suspicious wallet approvals.
- Registrar Engagement: Curve engaged with the domain registrar to regain control of the “curve.fi” domain.
Despite the frontend attack, Curve’s smart contracts and underlying infrastructure remained secure throughout the incident.
The attack had a notable impact on Curve’s native token, CRV. Following the breach, the token’s price dropped by over 8%, reflecting market concerns over the security of the platform.
Security firm Blockaid identified unusual activity from the compromised domain and advised users to refrain from interacting with the platform until the issue was resolved. This highlighted the broader risks associated with frontend attacks in the DeFi ecosystem.
This incident underscores the vulnerabilities inherent in the traditional DNS infrastructure, particularly for decentralized platforms like Curve Finance. To mitigate future risks, Curve Finance is considering the adoption of decentralized domain systems, such as the Ethereum Name Service (ENS), to reduce reliance on centralized registrars.
Additionally, Curve has expressed intentions to phase out the “.fi” domain due to prolonged downtime and limited support from the registrar. The new “curve.finance” domain is expected to offer better security and responsiveness.
In conclusion, while the May 2025 DNS hijack was a significant security incident for Curve Finance, the platform’s prompt and effective response helped mitigate potential losses and maintain user trust. The event also serves as a reminder of the importance of robust infrastructure and proactive security measures in the DeFi space.
