Yahoo says one billion of its accounts were breached back in August 2013.

It now stands as the largest hack of consumer data in history.

If you’ve ever had an account, even one you haven’t used for 10 or 15 years, your information may have been at risk for more than three years.

Yahoo apparently didn’t know about the hack until federal investigators got their hands on the stolen info from hackers on the dark web, according to cyber security expert and certified ethical hacker Charles Tendell.
