OpenSea

Many users of OpenSea, one of the largest NFT marketplaces in the world, received phishing emails requesting them to click a link and complete a verification within the next couple of days, threatening an account suspension. The email was not from OpenSea, and likely attempted to steal assets or the private keys of users who complied. It is not know how many users were affected.

This is a global/international case not involving a specific country.

About OpenSea

"The world’s first and largest digital marketplace for crypto collectibles and non-fungible tokens (NFTs). Buy, sell, and discover exclusive digital items." "Discover, collect, and sell extraordinary NFTs. OpenSea is the world's first and largest NFT marketplace."

"As the first and largest marketplace for Non-Fungible Tokens and Semi-Fungible Tokens, OpenSea provides a first-in-class developer platform consisting of an API, SDK, and developer tutorials. Feel free to browse around and get acclimated with developing smart contracts and interacting with NFT data."

"Fascinated by the [CryptoKitties] movement that was forming, Devin Finzer and Alex Atallah joined early adopter communities in Discord and started talking to users. With the OpenSea beta launch in December 2017, the first open marketplace for any non-fungible token on the Ethereum blockchain was born."

"Valued at $13 billion in a recent funding round, OpenSea has become one of the most valuable companies of the NFT boom, providing a simple interface for users to list, browse, and bid on tokens without interacting directly with the blockchain."

"On February 27, OpenSea appeared again with a phishing email attack. According to OpenSea’s official social media account, it was recently discovered that some users had received emails from openseateam.io (phishing links), the platform reminding users not to click on such phishing emails."

"We've seen some reports of users getting emails from http://openseateam.io."

"Dear customer, Due to OpenSea's migration to the new trading platform, we require all of our users to verify their accounts. All unverified accounts will be suspended on Monday, February 28th, 2022. We apologize for any inconvenience this might cause, but please keep in mind that our goal is to provide our customers with the safest and most reliable trading platform. To prevent your OpenSea account from getting suspended please verify it using the link below prior to Monday, February 28th, 2022. Best regards, OpenSea."
