Here’s how the latest massive Yahoo hack compares to other famous security breaches

Yahoo has seen better days. Just three months after disclosing a 2014 hack that stole details from more than 500 million user accounts, the beleaguered tech company on Wednesday informed the public of another hack, this time from 2013, which is believed to have affected more than 1 billion accounts.

Yahoo hasn’t yet identified the source of this latest attack, but believes an “unauthorized third party” is to blame, and that said party may be connected to the unnamed “state-sponsored actor” the company cited as the likely source of the hack disclosed in September.

In any case, Yahoo is now the victim of the two biggest known security breaches to date. And really, it’s not close. This chart from Statista isn’t totally comprehensive, but even still, the scope of this latest hack dwarfs anything that’s come before it.

That said, Yahoo is far from the only tech company to have issues protecting its users’ data. It’s been said time and again, but if you want a better chance at staying secure, use separate, legitimately random passwords (or use a password manager), turn on two-factor authentication, and always be skeptical of any email asking for account info of any sort.
