BookCrossing

In August 2022, the Bookcrossing Free Book Club took a data leak, due to which 1.5 million participants were injured. The violation revealed the email address, user names, full names, date of birth, IP addresses and passwords in the form of open text. The violation occurred due to the fact that Bookcrossing revealed a backup copy of the database almost 9 years ago (January 13, 2013).
