Executive Summary
In July 2018, the fitness app 8fit suffered a data breach that surfaced for sale on a dark-web marketplace in February 2019 as part of the large collection put up by the actor known as GnosticPlayers. Approximately 15.78 million records were exposed, including email addresses, names, genders, IP addresses, and passwords stored as bcrypt hashes. Some records also contained expired Facebook authentication tokens and profile thumbnail images.
ObscureIQ assessment: Exposure enables account takeover, phishing, and lifestyle profiling. Health and body-related behavior data can also create privacy harms or support targeted scams.
Breach Impact
Bcrypt hashing limited direct password recovery, but the email/name/IP set supported profiling and phishing, and inclusion in a widely traded multi-site collection increased cross-service exposure.
