According to the announcement, hackers gained access to BlockFi’s customer data, which was stored on Hubspot’s customer relationship management platform.
“Hubspot has confirmed that an unauthorized third party gained access to certain BlockFi customer data hosted on their platform,” the company said in a statement.
The Hubspot platform stores user data, particularly email addresses and phone numbers. Historically, attackers have used such information to conduct phishing attacks and gain access to accounts.
BlockFi reported that users’ personal information (passwords, passport information, and Social Security numbers) was “never stored on Hubspot.”
The company advised investors to be cautious about all messages coming from the company that are sent after the data leak.
