Ethereum Updates: DeFi's Vulnerability Exposed—Centralized DNS Attacks Lead to User Asset Loss
- Aerodrome and Velodrome DEXs suffered DNS hijack attacks, redirecting users to phishing sites via compromised registrars like Box Domains. - Attackers exploited centralized domain vulnerabilities to steal ETH, NFTs, and stablecoins, mirroring a 2023 incident that caused $100K+ losses. - Platforms urged users to bypass main domains and use decentralized mirrors, highlighting ongoing risks in DeFi's off-chain infrastructure. - Experts recommend DNSSEC and ENS adoption as solutions, while Dromos Labs plans
Aerodrome, the leading decentralized exchange (DEX) operating on
The attackers exploited flaws in domain registrar systems, enabling them to modify DNS settings and reroute visitors to malicious front-ends. Victims encountered misleading prompts, tricking them into approving transactions that drained their assets, including NFTs, ETH, and stablecoins
Investors were reminded that although on-chain contracts generally remain secure during such incidents, compromised front-ends present serious phishing dangers. "Always confirm contract interactions directly on-chain if the website is down,"
Aerodrome and Velodrome are crucial to their respective blockchain ecosystems. Aerodrome is the primary source of liquidity on Base, while Velodrome serves as a central hub for Optimism’s Superchain. The simultaneous targeting of both DEXs highlights the interconnected risks across ecosystems, as many protocols depend on them for routing and incentives
This event has reignited discussions about the importance of off-chain security in DeFi. While smart contracts are often robust, administrative controls and domain registrars remain susceptible to attacks. Experts suggest implementing measures such as DNSSEC, multi-factor authentication for domain accounts, and decentralizing front-ends using IPFS or
Industry responses include the introduction of solutions such as Infoblox’s DNS-based threat protection, which works with AWS to proactively block harmful domains
For now, users are encouraged to access decentralized mirror sites or interact directly with verified contract addresses. This incident is a stark reminder that, even as DeFi protocols bolster on-chain protections, off-chain vulnerabilities continue to pose significant threats to user assets
