LeaderID

A significant data exposure involving the Russian platform LeaderID occurred in late 2022. The incident involved the systematic collection of user data through web parsing techniques targeting the platform which is primarily used for educational events and professional development. The resulting dataset contains personal details for approximately 1.5 million registered users. The exposed information includes full names, contact details such as email addresses and phone numbers, geographic locations, and professional employment data. This collection of data highlights the risks associated with public profile visibility on professional networking and training platforms.
