Cyberattack on Tchap: an investigation opened by the Paris prosecutor's office

The Paris prosecutor's office has opened an investigation following the cyberattack targeting Tchap, the encrypted instant messaging service used by French civil servants. The cybercrime unit has taken over the case, which involves offenses related to obstructing an automated data system. The scale of the data breach appears considerable, according to initial estimates.

Over 640,000 messages exposed

According to the specialized website FrenchBreaches, claims published on the dark web indicate that over 643,000 messages exchanged by 73,000 public officials in 976 chat rooms have been exposed. This sensitive data was allegedly stolen during a cyberattack, the details of which remain to be determined. The attack is part of a series of malicious actions targeting several government ministries in recent days.

Questions about data security

The investigation will need to establish the exact circumstances of this security breach and identify the perpetrators of this cyberattack. The Tchap messaging service was designed to provide a secure communication channel for French government agencies. This intrusion raises questions about the protection of government data and the reliability of the systems meant to guarantee the confidentiality of state communications.
