- [Narrator] There are many examples of recent data breach…such as Equifax, eBay, Facebook and Home Depot.…But Yahoo was the victim of a huge data breach.…In 2013, hackers obtained real names, email addresses,…date of birth, and telephone numbers of three billion users.…Yahoo reported they had been using bcrypt…for hatching their passwords, a popular encryption library.…And this was all happening while Verizon…was considering purchasing the company.…So when I say that most companies are over confident…about their security measures, I'm not kidding.…
