Qubit Finance suffers largest DeFi hack of 2022

Qubit Finance, a decentralized lending and borrowing platform, was hacked for $80 million. The bridge collapsed in the largest DeFi hack of 2022. The money market platform connects lenders and borrowers efficiently and securely. 

Qubit's Ethereum-BSC bridge connects the two blockchains in a way that users deposit ERC-20 tokens and receive BEP-20 in return. The bridge was targeted by attackers, exploiting the "deposit" contract. 

Attackers input malicious data in the bridge's infrastructure and withdraw tokens on the Binance Smart Chain. The attacker's address still holds $80 million in BSC tokens. 

An official report by the Qubit team reads:

In summary, the deposit function was a function that should not be used after deposit ETH was newly developed, but it remained in the contract.
