Data of 7 million OpenSea users leaked online.
The email addresses of over 7 million users of the NFT marketplace OpenSea, compromised in a leak several years ago, have leaked online. This was reported by the head of information security at SlowMist under the pseudonym 23pds.
“The leaked addresses have been published in full after multiple instances of distribution. Please consider the risks associated with phishing and other potential cyberattacks,” the specialist warned.
He emphasized that the list of affected users includes well-known companies and key opinion leaders (KOLs) in the cryptocurrency industry.
The data was initially compromised in June 2022. An employee of the email service Customer_io, which serviced OpenSea, transferred the addresses of the marketplace's clients to a third party.
The SlowMist specialist recommended that the users involved be vigilant and use multi-factor authentication via the app instead of SMS.
Recall that in early January, CertiK analysts warned about the growing threat of phishing, citing an increase in the number of such attacks and the amount of damage.
