A massive database of 773 million unique email IDs and 21 million unique passwords has been posted online, discovered by security researcher Troy Hunt. According to him, several people had reached out to him and directed him toward this large collection of files, on the cloud service MEGA, specifically, 12000 files of about 87 GB in size. The data has been removed from the service since.

“However, 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.” Confirms Hunt.

The incident is considered one of the biggest data leaks happed in recent years, with the number of email addresses hacked being 772, 904, 991 and passwords 21, 222, 975 in number. The Yahoo data breach in 2013 affected nearly three billion accounts.

By visiting the site https://haveibeenpwned.com/ which Troy Hunt had integrated the database in, you can enter your email ID and check if it’s in the list of hacked ones. And by entering your password in the dialog box at https://haveibeenpwned.com/Passwords, you can check if your password is hacked or not.

If the check indicates that any of your data has been leaked, it is advised that you must immediately change the password of your email accounts, especially if you have been using the same password for a long time.
