No. of records: 3 billion
Year: 2013

Because Yahoo’s situation couldn’t possibly be any worse, the company announced that the data breach which it officially believed had affected 1 billion of its accounts actually affected them all – 3 billion in total. That’s pretty much the number of people who use the Internet at a global level. That’s not to say each account pertains to a single individual, since there are many people who have multiple accounts, but it’s still a massive number. The original breach announcement, made in December 2016, caused Verizon to cut down its acquisition price of Yahoo’s internet assets by $350 million.
