Base's leading decentralized exchange, Airport, experienced a DNS attack on November 22, 2024, redirecting users to a fraudulent site. This incident exposed vulnerabilities in the DeFi infrastructure, risking unauthorized transactions and approvals for its $400 million total value locked (TVL). The attack targeted the Web2 layer, specifically the domain registrar, rather than smart contracts. The central domains of Dromos Lab and Airport were hijacked on November 21, but the attack was swiftly detected and mitigated with the assistance of security partners. Plans for further security measures are underway.
