Recently, a prominent blockchain analytics platform, Nansen, fell victim to a security breach involving a third-party vendor. Upon further investigation, reports reveal that the hack’s effect extends beyond Nansen, affecting popular NFT marketplace OpenSea. 

OpenSea Breached

On September 23, OpenSea user MatrixXBT took to Twitter, warning users of a security breach affecting the NFT marketplace. The user shared a screenshot of an official email from OpenSea, acknowledging a security breach that exposed developer API keys. 

While the NFT platform claimed the breach wouldn’t immediately affect users’ interaction with the platform, the compromised API keys could potentially be exploited to affect users’ experiences. 

In the official email, OpenSea instructed users to immediately replace their old API keys with new ones. If you’ve been affected by the breach, here’s what you should do. 

How to Stay Safe

Creating a new API key is straightforward. Users can log in to their OpenSea profile and navigate to the Developer section on the settings page. After verifying their emails, they can then fill out the onboarding form and submit a request for a new API key.

While such breaches have become common lately, platforms have put extra measures to protect their users, which is why users weren’t immediately affected by this breach. Still, it’s worth protecting your account with security protocols such as two-factor authorization (2FA). 

Here are a few tips on how you can stay safe: 

  • Protect your recovery phrase by keeping it somewhere private. 
  • Double-check links, websites, and emails. Refrain from clicking any link unless it’s from a verified source. If the verified source has been compromised, take up the issue with other users and look for warnings and red flags. 
  • Ask for help from officials, and prioritize your safety and security. 
  • Verify and scan all addresses, such as contract, sender, and others, before doing anything permanent. 
  • Report any suspicious activity to the concerned departments as soon as possible. 
  • Set up additional security layers, such as two-factor authentication.
  • Always do your research. 

On the Flipside

  • OpenSea has yet to share a public statement about the data breach. 
  • This year, over $920 million in the cryptocurrency industry has been lost to cyber criminals.

Why This Matters

OpenSea’s security breach is another reminder of the importance of adequate security measures to protect oneself.
