THE BLOCK: Talis Protocol, an NFT marketplace on Injective, said an attacker exploited a bug in its marketplace and auction contracts on Saturday, taking about 5,700 escrowed NFTs and selling them into open collection offers. Onchain data reviewed by The Block shows the attacker netted about 445 INJ, or roughly $3,100. Most of the NFTs sold to bid bots for pennies, with a median sale of about 2 cents. The proceeds were swapped to USDT and bridged to Ethereum within about an hour of the exploit. Talis has paused listings and auctions and says it plans to return the NFTs to their original owners.
