Cosine: Hackers can sell NFTs blocked by OpenSea through the matchAdvancedOrders function of the Seaport protocol
2023-01-23 02:02
Odaily星球日报讯 BAYC第6大持有者Franklin发推称,一周内两次有人使用“Match Advanced Order”功能向其出售被标记为“可疑活动审查中”(黄色标记)的被盗BAYC NFT

对此,慢雾科技创始人余弦分析称,被OpenSea标记拉黑的NFT,黑客可以通过OpenSea Seaport协议的matchAdvancedOrders函数完成售卖。这样就绕过了OpenSea的安全策略(拉黑不可售卖),不过这里需要有买家bid了offer。
