The hackers, despite breaking into the database, would not have been able to make sense of the users information, were it randomly and cryptographically stored.
The security breach has again highlighted how the basic online security best practices have been neglected by leading companies, which follows after more than 5 million passwords were stolen from top networking sites, including Linkedin and eHarmony.
