An 87 GB dump of email addresses and passwords has been found that contain nearly 773 million unique addresses and just fewer than 22 million unique passwords.
Cloud service MEGA hosted nearly 773 million unique email addresses and just under 22 million unique passwords.
In a blog post, security researcher Troy Hunt said that more than 12,000 separate files and more than 87 GB of data were collected.
The data, dubbed Collection #1, is a set of email addresses and passwords with a total of 2,692,818,238 rows, supposedly from a variety of sources.
“What I can say is that my own personal data is in there and it’s accurate; right email address and a password I used many years ago, “wrote Hunt.” In short, if you’re in this breach, one or more passwords you’ve previously used are floating around for others to see.
“Some passwords, including his own, have been “dehashed ” which is converted back to plain text. Hunt said he got the information after several people contacted him with concerns about MEGA data, and the Collection #1 dump was also discussed at a hacking forum.
“The post on the forum referenced’ a collection of 2000+ dehashed databases and Combos stored by topic’ and provided a directory listing of 2,890 of the files,” Hunt wrote. Since then, the collection has been removed.
