It's now been confirmed that an additional 6.9 million 23andMe users had ancestry data stolen after hackers accessed thousands of accounts by likely reusing previously leaked passwords.

This is a much larger number of accounts than 23andMe previously disclosed in a Securities and Exchange Commission filing, which estimated that 0.1 percent of users—approximately 14,000, TechCrunch estimated—had accounts accessed by hackers using compromised passwords.
