OpenSea, the largest non-fungible token (NFT) marketplace, disclosed a data breach on Wednesday and warned users of phishing attacks that could target them in the coming days.
The online NFT marketplace says it has more than 600,000 users and a transaction volume that surpassed $20 billion.
The company's Head Of Security, Cory Hardman, said that an employee of Customer.io, the platform's email delivery vendor, downloaded email addresses belonging to OpenSea users and newsletter subscribers.
Since the emails stolen in the incident were also shared with an unauthorized external party, Hardman urged potentially affected users to be alert for phishing attempts impersonating OpenSea.
"If you have shared your email with OpenSea in the past, you should assume you were impacted. We are working with Customer.io in their ongoing investigation, and we have reported this incident to law enforcement," Hardman said.
"Because the data compromise included email addresses, there may be a heightened likelihood for email phishing attempts."
