23andMe has confirmed to BleepingComputer that it is aware of user data from its platform circulating on hacker forums and attributes the leak to a credential-stuffing attack.
Recently, a threat actor leaked samples of data that was allegedly stolen from a genetics firm and, a few days later, offered to sell data packs belonging to 23andMe customers.
The initial data leak was limited, with the threat actor releasing 1 million lines of data for Ashkenazi people.
A 23andMe spokesperson confirmed the data is legitimate and told BleepingComputer that the threat actors used exposed credentials from other breaches to access 23andMe accounts and steal the sensitive data.
The threat actor accessed a small number of 23andMe accounts and then scraped the data of their DNA Relative matches, which shows how opting into a feature can have unexpected privacy consequences.
