France’s official encrypted chat app Tchap was breached.
The National Cybersecurity Agency (ANSSI) flagged a compromise on June 7. The agency says an unknown actor accessed the system, but the Digital Affairs Directorate (DINUM) argues the intrusion was limited and no sensitive files were exfiltrated. The attacker, who posted on a hacking forum, claims to have retrieved user credentials and internal logs, though they provided no proof.
If the breach includes civil‑servant accounts, France loses a key argument for a sovereign alternative to WhatsApp and Telegram. The dispute also highlights how hard it is to verify damage when a state‑run service is involved.
The episode mirrors previous European attempts at home‑grown secure messengers that stumbled over implementation flaws, leaving officials to wonder whether the hassle of building their own was worth it.
