Collection # 1. By far the largest data breach in history. How large? Try 772,904,991 unique email addresses, over 21 million unique passwords compromised.
The Collection #1 data breach was first discovered by Have I Been Pwned security researcher Troy Hunt. Have I Been Pwned is an online tool that searches the web for your email or password. The service will alert you if your information has been compromised by any data breach ever. Most likely it has.
First appearing on the MEGA cloud service the data file contains over 87 gigabytes of data. According to Hunt the information remains on “a popular hacking forum.” The data was in a folder labeled with the name Collection #1. Though it is nearly impossible to determine where such a load of data came it may be a conundrum of several data breaches.
