Following a third-party security breach that left them potentially susceptible to malicious actors, OpenSea issued a security warning to specific users, urging them to rotate their API credentials.
OpenSea informed impacted customers via email that one of its vendors had experienced a safety concern that may have exposed information connected to consumers' OpenSea API keys. The leak prompted worries regarding the security of these keys, prompting OpenSea to act quickly.
OpenSea has asked customers to immediately stop using their current API keys and replace them with new ones. They emphasised that the current keys will expire on Monday, October 2. While the breach is not likely to have an immediate impact on users' integration with the platform, OpenSea warned that third-party access could potentially influence users' allotted rate limitations and usage criteria.
To reassure users, OpenSea stated that the newly created API keys will have the same rights and rate limits as the expiring ones. However, the site did not disclose the exact number of people affected by the incident, nor did it say whether any data besides API credentials was at risk.
This incident occurred not long after one of Nansen's third-party vendors experienced a similar security breach, which resulted in the exposure of specific customers' email addresses, password hashes, and blockchain addresses. Approximately 6.8% of its user base was impacted, according to Nansen, an on-chain analytics tool. Nansen said that many Fortune 500 businesses employ it, without specifically mentioning the vendor.
In addition to this new attack, OpenSea has already suffered security issues. OpenSea faced a data leak issue in June of the previous year, when customer emails were exposed owing to an employee's error while working with the email delivery partner, Customer.io. As a result of such data breaches, criminals frequently use compromised emails to start plausible phishing scams targeting clients.
Furthermore, in May 2022, OpenSea's Discord server was hacked, with cybercriminals promoting a bogus NFT minting event while claiming to be in conjunction with YouTube. These incidents highlight the persistent challenges and security risks that crypto-related platforms face in an ever-changing digital ecosystem.
