French authorities are investigating a security breach affecting Tchap, the nation's encrypted government messaging platform. The incident came to light on June 7 when the National Cybersecurity Agency (ANSSI) observed unusual activity.
Officials from the French Digital Affairs Directorate (DINUM), which manages Tchap, stated that the compromise involved a hijacked account providing access to public chat rooms. They maintain that private conversations, protected by encryption, were not affected. However, a self-proclaimed cybercriminal has challenged this assertion.
The individual claims to have exploited a valid account via social engineering, gaining access to more than 73,000 user accounts, substantial message volumes, and numerous media files. The hacker also alleges the compromised data included documents classified as 'Diffusion Restreinte,' a French government designation for restricted distribution, raising concerns about the extent of the breach.
