In January 2019, a collection of 5 parts appeared by a hacker forum, which are a combination of data from different sites. The collection contained 108 thousand files with a total size of 870GB. These files had 26 billion lines containing mail and password. However, many values ​​were repeated many times, and there were only 4.3 billion unique couples. Nevertheless, this collection is considered the largest leak in history.
