Curve Finance, a decentralized exchange, is still deeply investigating an apparent DNS exploit. Though a temporary glitch, this exploit would have forced users to an attack site. The breach, found Monday afternoon, necessarily led to urgent action from the site. Just as Curve Finance experienced a DNS hijack last year in 2022, hackers surged in on this major crisis. In total, this cyber attack resulted in losses of about $570,000.

On Monday afternoon, the company announced a preliminary answer to the incident. They are currently in negotiations to settle the suit and reinstate encrypted access for their users.

Details of the Potential Exploit

Curve Finance claimed, at first, that there was no indication of a compromise on the hackers’ part.

"While all smart contracts are safe, the domain name points to a malicious site which can drain your wallet! We are investigating and working on recovering the access. No sign of a compromise on our side." - Curve Finance

A few hours later, Curve Finance itself confirmed the hack. They assured their users that the breach was “confined strictly to the DNS layer” and did not touch their core infrastructure. Just last year, attackers were able to redirect users from Curve Finance’s official domain to a malicious site.

Expert Analysis of DNS Exploits

Meir Dolev, co-founder and CTO of Cyvers, described the broader nature of DNS exploits.

"DNS exploits are a form of social engineering at the infrastructure level. Attackers compromise the domain name system.” - Meir Dolev

This incident comes on the heels of a separate exploit against Vyper programming language versions and the CRV/ETH pool.

"These cloned sites can prompt users to connect wallets and approve transactions that drain funds. It's particularly dangerous because the average user can't easily tell the difference—they still see the correct URL." - Meir Dolev

In recent weeks, there has been a disturbing wave of attacks aimed at the underlying infrastructure of many crypto projects. These attacks remind us that strong security and user awareness are essential in the thriving decentralized finance (DeFi) ecosystem.

Increased Attacks on Crypto Infrastructure

Curve Finance is actively working to root out the source of this suspected DNS exploit. They are future-proofing our systems by rapidly accelerating and rolling out critical security improvements. The company sought to reassure users that their funds are not at risk and that the Curve smart contracts are still safe.
