On-chain insights platform Nansen has revealed that a third-party vendor’s system has been compromised. As a result, about 6.8% of the customers’ data have been affected.
Providing more details, the blockchain analytics platform stated that the event occurred on September 20, but it declined to mention the vendor impacted by the security breach.
In a brief description, Nansen revealed that the affected vendor was an established company that secured customer data for Fortune companies.
The security breach led to the customer’s data being compromised. According to the blockchain software firm, the cyber attack granted the intruders administrative rights to an account used to “provision customer access” to its platform.
Given this, their email addresses, the users’ password hashes, and their blockchain wallet addresses were exposed on the internet. The affected customers have been duly informed of the security incident and instructed to change their passwords.
Despite not naming the impacted party publicly, Nansen has instructed the vendor to release a public statement momentarily.
