About This Breach
In April 2020, Klub 31, an online regional directory and lifestyle portal for the city of Belgorod, Russia—named "Клуб31" (Club 31)—and serving as a community-driven guide to restaurants, cafés, bars, clubs, saunas, fitness clubs, hotels, and more, suffered a data breach that affected 767,543 users. The compromised data included email addresses and password hashes stored as MD5. Websites that handle user accounts must avoid outdated hashing algorithms like MD5 and adopt stronger encryption methods to protect personal data.
