Don't miss CoinDesk's Consensus 2022, the must-attend crypto & blockchain festival experience of the year in Austin, TX this June 9-12.

Watch out for phishing emails, says OpenSea, after staff at the world’s largest non-fungible token (NFT) marketplace discovered that an employee of Customer.io, a platform for managing email newsletters and campaigns, leaked the list of OpenSea customers’ emails to an outside party.

  • Email newsletter management platforms and Customer Relationship Management (CRM) software appear to be a weak spot for crypto firms as leaks of this data continue to happen at a high frequency.

  • In March, Hubspot, a platform similar to Customer.io, was hacked, affecting BlockFi, Swan Bitcoin, NYDIG and Circle.

  • Users of these platforms had their names, phone numbers and email addresses leaked to an outside party.

  • OpenSea said malicious actors may try to contact OpenSea customers via emails from domains that look similar to OpenSea.io such as OpenSea.org or OpenSea.xyz

  • On Twitter, OpenSea customers are complaining of an uptick in spam emails, calls and text messages.
