French Government Messaging Platform Breached by Mysterious ‘Misere’ Hacker

A breach of the French government’s secure messaging platform, Tchap, has resulted in the theft of personal data for over 70,000 government employees. The incident was initially attributed to a threat actor calling itself ‘misere,’ who claimed responsibility for the breach and the theft of 13.5GB of data. While the initial announcement downplayed the impact, experts suggest a sophisticated attack may have occurred, potentially involving the exfiltration of large amounts of data through legitimate API requests. The motivations behind the attack remain unclear, with speculation ranging from a minor embarrassment to a precursor for a larger cyberwar operation.
