7 Million OpenSea Users Exposed to Phishing Risks After 2022 Data Breach

Over 7 million OpenSea users are vulnerable to phishing and other attacks due to a 2022 data breach that recently made their email addresses fully public. According to blockchain security firm SlowMist’s chief information security officer, 23pds, the leaked data significantly increases the risk of phishing and other attacks.

Compromised Data and Risks

The leaked data includes email addresses belonging to prominent figures in the cryptocurrency industry, such as former Binance CEO Changpeng β€œCZ” Zhao, as well as well-known companies, key opinion leaders, and other influential individuals. This poses additional risks to the privacy and asset security of the crypto industry in the future.

Data Breach Incident

The email addresses in question were compromised in a June 2022 incident involving an employee of Customer.io, OpenSea’s email delivery vendor, who misused their access to download and share email addresses provided by OpenSea users and newsletter subscribers with an unauthorized external party.

Precautions and Security Measures

At the time, OpenSea advised users to be on the lookout for phishing and impersonation attempts, warning against downloading attachments or signing wallet transactions from email links. The company emphasized that all official communication would come only from its β€˜opensea.io’ domain.

As one of the largest NFT marketplaces, OpenSea users have been targeted by phishing scammers on several occasions. Experts advise users to stay vigilant by verifying email sources, avoiding clicking on unknown links, enabling two-factor authentication, and never sharing private wallet keys or sensitive information online.

Tips to Prevent Phishing Scams:

  • Verify email sources and check the domain name for authenticity.
  • Avoid clicking on unknown links or downloading attachments from suspicious emails.
  • Enable two-factor authentication to add an extra layer of security.
  • Never share private wallet keys or sensitive information online.

Phishing scams remain a major threat for cryptocurrency enthusiasts due to the many forms they come in, making them difficult to trace and even harder to prevent effectively.
