OpenSea, an NFT Marketplace, reports a serious email data breach

Following a data breach, OpenSea, a well-known NFT marketplace with a staggering $13 billion valuation in January, is alerting customers to Email phishing.


The largest NFT marketplace in the world said Wednesday night that a worker at Customer.io, an email vendor hired by OpenSea, used employee access to download and distribute email addresses of OpenSea's users and newsletter subscribers with an unauthorized third party.

The security compromise appears to be of enormous scope. The company stated that "if you have given your email with OpenSea in the past, you should presume you were impacted," and that it has reported the issue to law police. It also added that it is cooperating with Customer.io in an ongoing investigation.

According to data gathered by Dune Analytics, an open-source crypto analytics platform, more than 1.8 million customers have made at least one purchase using the Ethereum network on OpenSea.

According to a Customer.io official who talked with TechCrunch, "We believe this was caused by the acts of an employee who had role-specific access capabilities that were exploited." "We don't think the data of any other clients have been compromised, but we're still looking into it. The employee in question has been denied all access and suspended while we conduct our inquiry.

A target for cyberattacks has emerged among cryptocurrency firms as a result of the sector's exponential expansion and money inflow. Although decentralized, blockchain-based networks promise to offer greater security, most users today still favor centralized systems like OpenSea because of their ease.

As an illustration, in March, data breaches at BlockFi, Circle, and other companies were caused by a breach at customer-relations management software provider HubSpot. Justin Kan, a co-founder of Twitch, launched the NFT platform Fractal, but it had a rocky start in December when a scammer stole $150,000 by hacking the announcement bot.
