Nansen, a well-known crypto and blockchain analytics company, has reported a security breach involving one of its third-party vendors, affecting 6.8% of its users. The breach granted hackers access to admin rights for an account used to provision customer access to the Nansen platform.
While Nansen did not directly name the affected company, it described the vendor as “an established company that is used by many Fortune 500 companies” and other firms in the industry for data management purposes.
Users impacted by the breach had their email addresses exposed, along with some password hashes, and a small group had their blockchain addresses compromised. Nansen has identified and notified those affected, urging them to change their passwords. Importantly, the breach did not affect wallet funds.
Nansen is a prominent resource in the crypto space, providing on-chain analytics for many major players in the industry. The CEO of Nansen, Alex Svanevik, has previously expressed his belief that a future protocol will strike a balance between blockchain transparency, user privacy, and regulatory compliance.
In May, Nansen, like many others in the crypto industry, faced the challenges of a bear market and laid off approximately 30% of its workforce.
