UNITED NEWS INTERNATIONAL (UNI) — A DNA website said it underwent a security breach that exposed millions of users’ personal data.

MyHeritage said in a June 4 blog post that a security researcher found email addresses and password information belonging to MyHeritage users on a private server not connected to the site.

The company said the file contained email addresses from more than 92 million customers who signed up on the site before October 27, 2017.

The leaked data file also contained what are known as hashed passwords.

These aren’t the actual passwords users created to log in to the site, but rather one-way encrypted hashes of those passwords.

Hackers would need to decrypt hashed passwords before they could access personal accounts.

According to Bloomberg, past hacking attacks have managed to do so.

MyHeritage analyzes genetic histories through DNA samples submitted by customers.

The company said this data is protected by added layers of security and was not compromised.
