Curve Finance Warns Users of DNS Hijacking Attack

Curve Finance, a prominent decentralized finance (DeFi) protocol, has issued a critical warning to its users regarding a potential DNS hijacking attack on its website. The incident, which occurred on May 12, involved a hacker redirecting users to a malicious website, posing significant risks to user funds and data security. The team at Curve Finance promptly alerted users through a post on X, stating, “curve.fi DNS might be hijacked. Don’t interact!” This warning underscores the persistent security concerns within the DeFi space, where vulnerabilities in domain name systems (DNS) can lead to severe consequences.

The attack on Curve Finance’s DNS is the second such incident in a week, highlighting the ongoing challenges faced by DeFi platforms in securing their infrastructure. In a follow-up post, the Curve Team explained that the website “Points to the wrong IP” when users attempt to visit, indicating a DNS hijacking where the domain name is redirected to an incorrect IP address. This type of attack can compromise user security by leading them to fraudulent sites designed to steal sensitive information or drain their wallets. The team reassured users that their passwords are secure and that two-factor authentication has been in place for a long time. They have also reached out to the registrar for further investigation and resolution.

Curve Finance had previously experienced a similar front-end attack in August 2022, where attackers cloned the Curve Finance website and rerouted the DNS server to a fake page. Users who interacted with the platform during this incident had their funds drained into a pool operated by the attackers. This history of attacks underscores the need for enhanced security measures to protect against such vulnerabilities. The team emphasized that while all smart contracts are safe, the domain name pointing to a malicious site poses a significant risk to user wallets. They are actively investigating the issue and working on recovering access, with no signs of compromise on their side.

In response to the recent attack, onchain security firm Blockaid detected unusual activity from the Curve website and warned users to avoid interacting with the platform until the issue is resolved. Blockaid described the potential attack as a “frontend attack,” where hackers target the part of the website users interact with, such as buttons, forms, or text, to steal sensitive data. The firm advised users to refrain from signing transactions and avoid interactions with the DApp until the issue is resolved, emphasizing the importance of user vigilance during such incidents.

This is the second time Curve Finance has been targeted in the last week. On May 5, a hacker took over the official X handle, but the team clarified that the incident was limited strictly to the X account and that no other Curve accounts were affected. No security issues were found on their side, and no user funds were impacted. Access to the Curve Finance X account was restored quickly, and the cause is still under investigation. This incident highlights the broader issue of account hijacking on social media platforms, which has affected other high-profile accounts this year, including the Tron DAO account and a member of the UK’s Parliament.

The recent security breach has not only impacted Curve Finance but has also affected multiple projects that rely on Curve’s data architecture. Convex Finance and Resupply, which depend heavily on Curve for operational data, reported significant outages while assuring users that their platforms are secure. Users on these platforms may experience reduced functionality until Curve’s domain is restored. Convex Finance’s platform, which relies significantly on data from Curve’s services, has left this information largely unavailable, affecting user interactions. As stated in their recent update, Convex Finance’s website uses data from Curve, and Curve’s domain name is currently suffering an attack.

DNS hijacking poses significant risks, allowing attackers to redirect users to fraudulent versions of legitimate platforms. This incident serves as a stark reminder of the vulnerabilities that associated projects face. Traditional hacking methods persist as valid concerns, particularly targeting web frontends that lack the inherent protections present in decentralized smart contracts. As emphasized by key projects, while backend systems remain intact, it is crucial for users to avoid initiating transactions or interacting with any dApps related to Curve during these critical moments. Curve Finance has stated that while all smart contracts are safe, the domain name points to a malicious site which can drain user wallets. The company is investigating and working on recovering access, with no signs of compromise on their side.

Curve Finance has begun collaborating with affected partners to mitigate the issue, and further updates are anticipated as the investigation unfolds. This breach highlights a significant gap in frontend security within DeFi projects, showcasing that although decentralized, these platforms are not immune to traditional attack vectors. This evolving situation draws attention to the imperative for DeFi projects to enhance security protocols, especially concerning frontend vulnerabilities that could jeopardize user funds. As the incident with Curve Finance unfolds, it illustrates the necessity for robust security measures within the decentralized finance arena. Users should remain vigilant and informed, particularly in light of the latest developments. The ongoing scrutiny in DeFi security will undoubtedly shape future protective strategies aimed at mitigating similar threats.
