France’s government uses Tchap as an internal messaging service for public workers. The app is known for protected communication and is part of the country’s move toward local digital tools.
On June 7, France’s national cyber security agency confirmed that Tchap had been breached. France’s digital affairs office then opened a broad investigation. Officials said they identified the account used in the attack and cut off its access.
They are still examining what information the attackers reached and how much data may have leaked. Tchap users also received a warning message. It reminded them that content shared in public chat rooms is not protected by end-to-end encryption.
According to reports, the attacker claimed responsibility and said some files had been taken. The person or group also claimed access to fixed LDAP login details and said about 14 GB of documents and files were stolen, including email addresses and meeting links.
