NFT: 1.8 million OpenSea users affected by massive messaging breach

OpenSea, one of the most popular NFT marketplaces, has warned its users. Possibly 1.8 million of them may have received a phishing email. This risk follows a breach of the Web3.0 giant’s messaging system. OpenSea, valued at nearly $13 billion as of January 2022, is a staple in the NFT universe.

The violation of OpenSea users’ email addresses allegedly originated internally at one of its partners

It is alleged that an employee of, an email provider under contract with OpenSea, has allegedly abused its employees’ access to download and share OpenSea users’ email addresses. . In addition to simple users, he also had access to newsletter subscribers. He would have passed them on to an unauthorized third party.

OpenSea is partnering with to investigate this incident

The magnitude of the security breach seems enormous. The company said: “ If you’ve shared your email with OpenSea in the past, assume you’ve been affected She added that she was cooperating with in an ongoing investigation and reported the incident to the police.

1.8 million users potentially affected

Web3.0, the preferred target of cyber-attacks

Crypto startups have become a target for cyber-attacks as the industry sees explosive growth and large cash flows. Decentralized blockchain-based networks promise to provide better security, but average users are now turning to centralized services like OpenSea. This type of provider has many advantages, but also poses a higher risk in terms of the security of information and cryptocurrency assets. Examples of cyber attacks exist in the Web3.0 world, such as the data breach at HubSpot, a customer relationship management software company. Violations like this have created phishing risks for Trezor users.

Other blockchain companies like OpenSea are potential targets

Fractal, an NFT platform launched by Twitch co-founder Justin Kan, got off to a rocky start in December after a scammer hacked into the ad bot to raise $150,000. One of the biggest crypto heists to date was the $625 million theft of Ronin, a blockchain network connected to the play-to-win Axie Infinity.

Security on Web3.0 still remains unstable. Therefore, it is probably the sector with the most future in the blockchain universe. Theoretically, the decentralized nature of blockchain and Web3.0 should provide better security. However, many platforms, wallets, etc. remain exposed due to their much more centralized aspect. Besides, hackers always find loopholes and the loot is juicy. Blockchain-based services represent astronomical sums of money.
