Data breach — Low

On 16 October 2026, an attacker claimed on a cybercriminal forum to have obtained and published 3,400 documents from gltf.fr, the website of the Grande Loge Traditionnelle de France. The claim is part of a series of publications announced for 17 October that also target other organisations. The content of the documents is not established, and it is unknown whether they include members' personal data. How the files were obtained, whether they are authentic, and whether the organisation's systems were breached have not been verified, and the organisation has not commented so far.
