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.
Payment Info Also Leaked?
Nansen is a prominent blockchain analytics platform that provides on-chain insights on key blockchain protocols in the fast-growing crypto landscape.
In 2021, Nansen raised $12 million from investors such as Andreessen Horowitz (a16z) and Coinbase Ventures. The blockchain analytics startup’s services are highly sought after by cryptocurrency investors and blockchain-focused funds, including Pantera Capital and Defiance Capital.
The platform recently launched its newer version called Nansen 2, which is currently in beta mode.
While it did not state if the security breach impacted customers’ payment details, some X users have reported compromised payment details.
An X (formerly known as Twitter) user with the designation Nick Bax.eth (@bax1337) stated that his PrivacyHQ credit card, which he only used for a single payment on the Nansen platform, was impacted.
He shared a screenshot of the email forwarded from the analytics platform regarding his compromised payment information.
@nansen_ai just sent out a data breach notification.

My @PrivacyHQ credit card, *only* used for a single nansen payment, got used back in July.

Another group of users mentioned that Nansen’s customers’ payment details may have leaked despite the blockchain service intentionally omitting that detail.
