DeFi protocol Arcadia Finance hacked on Ethereum and Optimism for $455k


A hacker drained roughly $455,000 from non-custodial decentralized finance (DeFi) protocol Arcadia Finance by exploiting a code vulnerability.

Blockchain investigator PeckShield alerted in regards to the hack on Arcadia Finance, stating the trigger as “the dearth of untrusted enter validation.” The code supposedly lacked a validation mechanism to cross-check unverified inputs. This loophole allowed the hacker to empty funds price roughly $455,000 from Ethereum (darcWETH) and Optimism (darcUSDC) vaults collectively.

Arcadia Finance has not but responded to Cointelegraph’s request for remark.

Arcadia Finance confirmed the hack two hours after PeckShield’s intimation and subsequently paused the contracts to stop additional bleeding of funds.

Whereas the investigations are underway, Arcadia’s code homes one other vulnerability, which may show catastrophic for the protocol if exploited. According to PeckShield:

“As well as, there’s a lack of reentrancy safety, which permits for the immediate liquidation to bypass the inner vault well being examine.”

Nearly all of the stolen funds — roughly 180 Ether (ETH) — have been from Optimism, and have been washed through Twister Money. Nonetheless, the stolen tokens — price over $103,000 on the time of writing — on Ethereum stay parked on the suspected pockets handle.
