OpenSea Bug Allows Attackers to Steal Bored Apes at Massive Discounts

A bug on the non-fungible tokens (NFT) marketplace OpenSea has allowed scammers to purchase at least $1 million worth of blue-chip NFTs across multiple different wallets for significantly much less than their collection’s floor price.
