MyFitnessPal Data Breach (2018)

Around 150 million users of the MyFitnessPal app experienced a data breach in 2018 that compromised their personal information. The breach involved unauthorized access to usernames, passwords, and email addresses. While Under Armour, the parent company of MyFitnessPal, quickly reset the passwords of affected users, it was later discovered that the old passwords were being sold on the dark web.
