The peer-to-peer trading platform NFT Trader became the target of a hacker attack, as a result of which multimillion-dollar digital assets were stolen.

Among the stolen digital assets were unique NFTs from well-known collections such as Bored Ape and Mutant Ape Yacht Club, World of Women NFTs, VeeFriends, and Art Blocks.

The NFT Trader team confirmed the incident and announced that the perpetrators exploited "old smart contracts." The attacks ceased after updating the contracts on the platform to address the vulnerability related to the possibility of reentrancy.

The hacker, in turn, posted a public message on the blockchain in which he offered to return the tokens in exchange for a ransom: 3 ETH for Bored Ape and 0.6 ETH for Mutant Ape.

In the past few weeks, there has been a significant increase in activity in the non-fungible token (NFT) market. Over the past 7 days, the NFY sales volume has increased by 52.81%, reaching $503.35 million.

The main driver of this growth has been "whales," who have collectively spent $276.79 million on purchasing NFTs issued on the Bitcoin network.

The most significant deals of the week were the sales of Fidenza #985, which fetched $277 thousand, and an NFT version of a Van Gogh painting, sold for $263 thousand.
