Collection #1 data breach

Troy Hunt, a well-known computer security expert, and creator of the Have I Been Pwned service has reported about new major data breach and leak of personal information of users. The hackers have posted 87 GB database containing 773 million unique email addresses and 22 million unique passwords.

The stolen information — a folder called Collection # 1 —was originally published on the MEGA cloud service, from where it was soon removed.

The Wired stated, it is the largest known publication of stolen data. However, this is not the first such leak (and certainly not the last): in recent years hundreds of millions of passwords and other data from users of popular services have been in the hands of hackers, for instance, infamous Facebook data breach.

However, according to  Krebs on Security reports, Collection #1  isn’t the biggest problem as there’s a 526GB Collection #2, a 37GB Collection #3, a 178GB Collection #4, a 42GB Collection #5, and 2 more folders 126GB worth of sensitive information.

For now, no one knows how this information was obtained, who is behind the data breach and why it happened in the first place.  According to Troy Hunt, the base was collected from various leaks belonging to different years.

Considering that the hackers did not even try to sell this database, but simply published it, we can assume that it does not pose a particular threat and contains very outdated data.

How to check if you’re affected 

Hunt has already updated the base of his site Have I Been Pwned so that those who wish can quickly check if your mailing address is among others in “Collection No. 1” and, if necessary, change your password.

Also, you can even subscribe to an automatic newsletter to find out when your mailbox was affected by another leak.

This incident serves as an excellent reminder that you cannot use the same password for different sites because it is in such cases that attackers can take advantage of the situation and easily hack a user account in a particular service by simply substituting the login/mail and password combination from the database.
