Genetic testing company 23andMe said Monday that hackers were able to access the data of about 6.9 million people, far more than the company previously acknowledged.
The finding is the result of an investigation 23andMe launched in October, after at least one list of people whom the site identified as having Ashkenazi Jewish ancestry was posted online.
The police have been using that data to solve crimes for years. That’s how they found the golden state killer and others.
