Nansen third-party vendor suffers security breach, user data affected

The crypto analytics provider says a security breach of a third-party vendor has affected nearly 7% of users in the system who were promptly informed of the incident.

Prominent crypto and blockchain analytics company Nansen posted on social media platform X (formerly Twitter) that one of its third-party vendors suffered a security breach affecting 6.8% of its users.

According to Nansen, the breach gave hackers access to admin rights for an account used to “provision customer access” to its platform.

Without directly naming the company affected, it said this vendor is “an established company that is used by many Fortune 500 companies,” along with other companies in the industry, to manage data. 

The users affected by the breach reportedly had their email addresses exposed, along with some password hashes, and some had their blockchain addresses compromised.

Nansen said it has identified and informed those affected and asked all to change their passwords. It also clarified that wallet funds were unaffected by the event.
