“There are breaches, and there are megabreaches, and there’s Equifax,” Brian Barrett reports for Wired. “But a newly revealed trove of leaked data tops them all for sheer volume: 772,904,991 unique email addresses, over 21 million unique passwords, all recently posted to a hacking forum.”

“The data set was first reported by security researcher Troy Hunt, who maintains Have I Been Pwned, a way to search whether your own email or password has been compromised by a breach at any point,” Barrett reports. “The so-called Collection #1 is the largest breach in Hunt’s menagerie, and it’s not particularly close.”

In raw form, it comprises 2.7 billion rows of email addresses and passwords, including over a billion unique combinations of email addresses and passwords,” Barrett reports. “Not only is this the largest breach to become public, it’s second only to Yahoo’s pair of incidents — which affected 1 billion and 3 billion users, respectively—in size.
