BlockSec revealed identifying a serious vulnerability in NBA’s latest NFT collection that allows attackers to mint a large number of NFTs, without paying any tokens.
The National Basketball Association revealed pausing minting of its new non-fungible token collection, dubbed – The Association – after a major loophole was detected by BlockSec. Less than a day after the league announced the minting of its Ethereum-based non-fungible token , it recognized the issues with the smart contract that triggered the “Allow List” supply to sell out prematurely.
This essentially means that the contract fails to ensure that the signature can only be used by the user once. The vulnerability also allowed the attacker to reuse a privileged user’s signature and mint tokens to themselves.“We are surprised that how such a vulnerability can exist in a popular NFT project. The whole community needs to pay more attention to the security of the contract.”100 NFTs and sell them on the OpenSea marketplace.
Leveraging Chainlink oracles will allow each player’s NFT appearance to alter automatically. The dynamic NFTs will change in appearance based on the performance of the players. In short, more accomplishments during the 2022 NBA playoffs mean players will see more visual changes in their digital collectibles, throughout the course of the postseason tournament.
