The Biggest Data Breach of All Time 773 Million Email Addresses And 21 Million Passwords Exposed

It may be time to change all your passwords. If you thought Facebook leaking your data to a third party was bad, wait till you hear this. As many as 772,904,991 unique email addresses and over 21 million unique passwords have been leaked online. This specific data dump, called as "Collection #1," is an aggregation of multiple leaked databases that include passwords that have been cracked and holds within itself 2.7 billion records.



The data set was first reported by security researcher Troy Hunt, who run the Have I Been Pwned website. This website lets you confirm if your email address or password have been compromised by a breach at any point of time. Hunt, in a blog post confirms, “the unique email addresses totalled 772,904,991 and there are 21,222,975 unique passwords.”

The Collection #1 is over 87GB worth of data, and contains over 12,000 separate files. As it turns out, this data leak was posted on the cloud based sharing website, Mega. Hunt refers to Mega as a “hacking forum” and clarifies that this data seems to have been taken down since.
