Threat Score
A compromise of a Tchap user account allowed an attacker to access and scrape data from public (non‑encrypted) chat rooms on the French government messaging platform, impacting roughly 73,467 accounts (~9% of registered users). Exfiltrated data reportedly includes user names, email addresses, avatars, organization affiliation, meeting links, account/device metadata, hardcoded LDAP credentials, and approximately 13.5GB of documents/media; DINUM blocked the malicious account and notified CNIL while investigating.
