The NFT cash market platform permits customers to stake their NFTs on the platform, usually open staking for fashionable collections like Bored Ape Yacht Membership, to obtain tokens like ETH.

Though the hacker was in a position to drain out greater than 1,300 wETH ($1.4 million), the ERC20 tradable model of ETH, Omni acknowledged that the theft didn’t have an effect on prospects’ funds. The corporate added that solely inner testing funds have been impacted because the platform continues to be in beta testing mode.

To deal with this, hackers usually depend on reentrancy as they’re able to drive by utilizing borrowed WETH to purchase extra NFTs earlier than the liquidation happens.

Moreover, Zhou added that the hacker then used the Doodles NFT acquired with the preliminary mortgage as collateral to borrow extra WETH. Nevertheless, as Omni had failed to acknowledge this new place, the hacker might withdraw the NFTs with out paying again the mortgage.
