Security News > 2023 > September > Crypto firm Nansen asks users to reset passwords after vendor breach
Ethereum blockchain analytics firm Nansen asks a subset of its users to reset passwords following a recent data breach at its authentication provider.
Nansen is a popular entity in the cryptocurrency space, offering users insights into Ethereum wallet activity, helping identify emerging projects, and generally helping people make informed investment decisions.
In a letter sent to impacted users, Nansen says they learned on September 20t that one of their third-party vendors suffered a data breach.
Nansen stopped the malicious activity shortly after the vendor informed them about the incident, but the ensuing investigation confirmed that user data was compromised.
All impacted users have been informed about the breach via email notifications, while Nansen's support has also contacted them to request a password resetting action.
It would be advisable for all Nansen users, regardless of whether they have received a notice, to reset their passwords out of an abundance of caution.
