Millions of OpenSea User Emails Leaked in 2022 Now Fully Public

Millions of email addresses stolen in the 2022 OpenSea data breach have been publicly leaked by hackers. Cybersecurity experts warn that this disclosure has created more channels for phishing scams. In June 2022, OpenSea discovered that an employee of its email automation vendor, Customer.io, revealed over seven million customer email addresses to an unauthorized party. OpenSea advised users who had shared their email with the platform to assume they were impacted. The company reported the incident to law enforcement and collaborated with Customer.io in their ongoing investigation. Although the data breach occurred years ago, the exposed email addresses were not publicly available until 2024. The situation worsened when the hacked data was made available online.
