OpenSea, a non-fungible token marketplace, fell victim to a hack on its main Discord channel. The threat actors breached the network and posted fake announcements about partnerships between OpenSea and other projects and also a link to a phishing website. This phishing attempt compromised 13 wallets and allowed them to stole Founders’ Pass NFT, valued at 3.33 Ether, equivalent to around $8900. The company issued warnings to users urging them not to follow any of the links posted on the channel.
