23andMe confirms hackers stole ancestry data on 6.9 million users

TechCrunch: “On Friday [December 1, 2023], genetic testing company 23andMe announced that hackers accessed the personal data of 0.1% of customers, or about 14,000 individuals. The company also said that by accessing those accounts, hackers were also able to access “a significant number of files containing profile information about other users’ ancestry.” But 23andMe would not say how many “other users” were impacted by the breach that the company initially disclosed in early October. As it turns out, there were a lot of “other users” who were victims of this data breach: 6.9 million affected individuals in total. In an email sent to TechCrunch late on Saturday, 23andMe spokesperson Katie Watson confirmed that hackers accessed the personal information of about 5.5 million people who opted-in to 23andMe’s DNA Relatives feature, which allows customers to automatically share some of their data with others. The stolen data included the person’s name, birth year, relationship labels, the percentage of DNA shared with relatives, ancestry reports and self-reported location. 23andMe also confirmed that another group of about 1.4 million people who opted-in to DNA Relatives also “had their Family Tree profile information accessed,” which includes display names, relationship labels, birth year, self-reported location and whether the user decided to share their information, the spokesperson said. (23andMe declared part of its email as “on background,” which requires that both parties agree to the terms in advance. TechCrunch is printing the reply as we were given no opportunity to reject the terms.)”
