Berk Ucak/Getty Images The French government's in-house messaging service, Tchap, has been breached in a cyber attack. On June 7 it became clear to the French National Cybersecurity Agency (ANSSI) that the encrypted messaging platform had been compromised, prompting an investigation by the French Digital Affairs Directorate (DINUM), which developed and manages the app.

In a press release published by numerique.gov, the dedicated website for France's digital strategy, it was confirmed that the account behind the attack had been identified and blocked. Exactly what data they were able to extract is still being investigated, but a message was sent to all Tchap users to remind them that the content of public chatrooms is not encrypted.
