France's government messaging app Tchap was breached after an attacker used social engineering to compromise a single account on the education shard (matrix.agent.education.tchap.gouv.fr), allegedly scraping ~650,000 public messages, data on ~73,000 accounts (emails, device metadata), and ~13.5GB of documents; DINUM blocked the account, notified CNIL, and emphasized that private end-to-end encrypted chats were not exposed.
