Binance boss says Exchange froze 83% of Curve Finance hack funds, domain provider says exploit was DNS cache poisoning
Four days ago, the crypto community was notified that the Curve Finance frontend was being exploited. Curve fixed the situation but $570,000 was removed from the defi protocol. The attackers, however, decided to send the funds to crypto exchanges. Binance CEO Changpeng Zhao (CZ) tweeted about the exploit the day it happened.
“Curve Finance had their DNS hacked in the last hour”, CZ wrote. “Hacker put a malicious contract on the homepage. When the victim approved the contract, it would empty the wallet. Damage is approximately $570,000 so far. We monitor. In addition to Binance monitoring the situation, the Fixedfloat exchange managed to freeze some funds.
“Our security service has frozen part of the funds amounting to 112 [ether]. In order for our security department to fix what happened as soon as possible, please email us,” Fixedfloat wrote the day of the hack. Then three days after the hack, on August 12, CZ explained at 1:07 a.m. (EST) that Binance had recovered around 83% of the funds.
“Binance froze/recovered $450,000 of stolen funds from Curve, accounting for over 83% of the hack”, CZ tweeted Friday. “We work with [law enforcement] to return funds to users. The hacker kept sending the funds to Binance in different ways, thinking we can’t catch him,” CZ added.
Curve Finance retweeted CZ’s statement and noted earlier today that the team had a brief report from the domain provider [iwantmyname.com] and said, “In short: DNS cache poisoning, not nameserver compromise,” Curve Finance Explain while sharing the report. “No one on the web is 100% immune to these attacks. What happened STRONGLY suggests starting to switch to ENS instead of DNS.
The report from domain provider iwantmyname.com confirms Curve’s claims. “It appears that a customer’s domain was targeted,” the disclosure report from iwantmyname.com details. “Our external provider’s hosted DNS infrastructure has apparently been compromised and the DNS records for this domain have been changed to point to a cloned web server. Further investigation with the external provider indicates that it was DNS cache poisoning rather than a compromised nameserver.
