The 2022 OpenSea data breach is back in the spotlight, as over seven million email addresses are now publicly available.

Timeline of the Breach

In June 2022, OpenSea was at the peak of its popularity, ranking among the top 400 websites globally with over 120 million monthly visitors. During this time, an employee of Customer.io, responsible for email automation, exploited their access to extract and share email addresses from OpenSea’s user database with unauthorized third parties. The breach primarily affected the platform’s user base but also compromised key figures in the cryptocurrency sector, including Binance's CEO Changpeng Zhao, leading firms, and industry influencers.

Full Data Disclosure

Cybersecurity expert 23pds confirmed on X (formerly Twitter) that the email addresses, including those of industry leaders, are now widely accessible. These individuals are prime targets for phishing attacks that can lead to severe financial and reputational harm. 23pds emphasized that these email addresses could be used by threat actors to create convincing phishing attacks.

Precautionary Measures for Users

SlowMist's security expert advises all users whose email addresses were part of the breach to take immediate precautions. These include creating strong, unique passwords for each account and using password managers for secure storage. Two-factor authentication (2FA) is also strongly recommended, with a preference for authenticator apps over SMS-based 2FA due to their increased security. OpenSea also reminded users to be cautious of emails resembling official communications from unofficial domains like "opensae.io", "opensea.org", or "opensea.xyz".

Phishing attacks pose a major threat in the crypto space, with over $1 billion lost to such scams in 2024 alone. The OpenSea breach underscores the need for enhanced security measures across all levels of platform infrastructure, particularly when dealing with sensitive user data.
