Security expert Troy Hunt has exposed a the largest publication of breached data in history, affecting over 770 million email addresses and 21 million passwords.

The new finding, called “Collection #1” by Hunt, consists of 2.6 billion rows and is made up of “many different individual data breaches from literally thousands of different sources.”

The database going back as far as 2008 is a staggering 87GB in size, and comprises 1.1 billion unique combinations of email addresses and passwords – many of which have been “dehashed,” or cracked and converted back to plain text.

This is when treating the password as case sensitive but the email address as not case sensitive. This also includes some junk because hackers being hackers, they don’t always neatly format their data dumps into an easily consumable fashion. (I found a combination of different delimiter types including colons, semicolons, spaces and indeed a combination of different file types such as delimited text files, files containing SQL statements and other compressed archives.)

The unique email addresses totalled 772,904,991. This is the headline you’re seeing as this is the volume of data that has now been loaded into Have I Been Pwned (HIBP). It’s after as much clean-up as I could reasonably do and per the previous paragraph, the source data was presented in a variety of different formats and levels of “cleanliness”. This number makes it the single largest breach ever to be loaded into HIBP. -Troy Hunt
