CyberNews reports that RockYou2021, an homage to 2009’s RockYou data breach, is an almost 100GB text file containing close to 8.4 billion (yes, billion) emails and passwords. The list presumably has been collected from several previous data breaches and hacks. This makes it the largest collection of compromised account info in history, and could likely effect all 4.7 billion people in the world who have an online presence.

The user who uploaded this list is presumed to have collected and compiled the data from several years worth of previous attacks, including the original RockYou breach that it's named after.
