OpenSea, the largest non-fungible token marketplace, disclosed a data breach on Wednesday and warned users of phishing attacks that could target them in the coming days.
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.
Examples of domains that could be utilized in phishing attacks targeting OpenSea users include opensea.org, opensea.
In the past, OpenSea users have been targeted by threat actors impersonating fake support staff and by a phishing attack that left more than a dozen users without hundreds of NFTs worth roughly $2 million.
In September, OpenSea also closed a bug that could let attackers empty OpenSea account owners' cryptocurrency wallets by luring them to click on malicious NFT art.
