DeFi lending protocol Ola Finance introduced an exploit that allowed an attacker to steal $3.6 million.
The attacker took advantage of a reentrancy bug in Ola’s wise contracts.
This will come just a week after the exploit of Axie Infinity’s Ronin network.
It was no April Idiot joke for Ola Finance when above $3.6 million had been siphoned off the protocol in a recent exploit. DeFi protocols have been an easy focus on for hackers as much more and additional stability breaches have surfaced above the final few of a long time.
A further DeFi hack
On April 1, decentralized lending protocol Ola Finance revealed that it suffered an exploit that allowed hackers to grab $3.6 million worth of cryptocurrencies from the platform.
Ola Finance released a summary of the exploit, revealing that the worth stolen from the protocol summed up to all-around $4.67M in ETH, BTC, and FUSE selling prices. The attackers managed to steal all-around 216,964 USDC, 507,216 BUSD, 200,000.00 fUSD, 550.45 WETH, 26.25 WBTC, and 1.24 million FUSE.
PeckShield, a blockchain security company that labored with Ola to look into the exploit, disclosed that the attacker took gain of a ‘reentrancy’ bug in just one of Ola’s sensible contracts. The hack was produced doable because of to the incompatibility in between Compound fork and ERC677/ERC777-centered tokens, which have the constructed-in callback capabilities misused to allow for reentrancy to drain the lending pool.
Ola’s DeFi protocol operates throughout many blockchains. In the current assault hackers focused its deployment on the Fuse network. Fuse is an Ethereum Virtual Machine-suitable blockchain with around $12.8 million in overall worth locked (TVL) ahead of the attack.
Hackers Targeting DeFi
The Ola Finance hack will come only a number of days just after the $625 million exploit of Axie Infinity’s Ronin network. The Ronin hack is a single of the biggest in DeFi record, where by a whopping 173,600 ETH and 25.5M USDC had been drained from Ronin bridge just last 7 days.
Moreover, the reentrancy attack utilised for the Ola Finance hack is not the initial one this yr. On March 16, attacker siphoned around $11 million from Agave and Hundred Finance by introducing a reentrancy bug and employing a flash financial loan exploit to siphon resources, as reported by FXEmpire.
Even even though the Ola Finance hack is somewhat lesser than the aforementioned assaults, it reminds us of the multimillion-greenback thefts that are now rather common in DeFi.
