It's not known exactly how many people were caught up in the data breach, but 340 million files were uploaded to a publicly accessible server.
The records include home addresses, phone numbers, email addresses and other sensitive information for named individuals.

They also record their hobbies, interests and habits, as well as the number, age, and gender of any children they have.
The leak is thought to be one of the biggest recent security breaches of its kind.
