Popular NFT Marketplace OpenSea, announced a data breach. And the email addresses of the users are now vulnerable to external attack.

Why the Opensea Data Breach? 

The Opensea marketplace stated that the platform was not the cause of the data breach.

The breach occurred because a worker at Customer I.O took advantage of the access to the email addresses of customers and disclosed the information to an external source.

According to the Opensea market, all the customers that have given their email addresses to the platform are vulnerable to attack. Consequently, they should therefore be careful against phishing attempts that may arise in the future.

Opensea sent a tweet to customers saying that the hackers may send emails with fake domain names. The domain names are mocks of the original opensea.IO such as opensae.IO or

The Opensea marketplace has contacted law enforcement agents to conduct further investigations on the issue.

Other Firms that Have Experienced Data Leaks

Hubspot– a customer management software comparable to Customer I.O–incurred a data breach in March. In this case, the hackers obtained the details of customers such as first and last names, phone numbers, email addresses e.t.c.

Also, in March Ronin Bridge– a link used to make deposits and withdrawals in the  Axie Infinity NFT game– was subject to an attack by hackers which led to the siphoning of over $625 million.
