OpenSea NFT Marketplace Faces Insider Hack

OpenSea, the largest nonfungible token (NFT) marketplace, this week announced that an employee of one of its email vendors, Customer.io, accessed and downloaded the company’s email list.

“The data breach disclosed today is a stark reminder of the dangers of insider threats,” he says. “In this case, an authorized user misused their employee access to download and share email addresses of OpenSea’s users and newsletter subscribers with an unauthorized external party.”
