Venus1337 is a forum-based threat actor associated with offering allegedly stolen datasets for sale. In September 2026, the actor claimed compromises affecting L’Orange bleue, a French fitness-club network, and the Belgian table-tennis organizations AFTT and FRBTT. The claimed datasets contained membership and subscriber information, contact data, payment-related information, profile photographs, sports-affiliation records, and purported administrator credentials. Venus1337 alleged that the Belgian intrusions involved exploitation of an insecure file-upload feature for remote code execution, deployment of a web shell, recovery of credentials from application files, and SQL database extraction. The actor separately alleged use of an insecure authorization design and automated export collection against the French fitness network. The technical intrusion details, claimed data volumes, and authenticity of the datasets had not been independently verified.

Cybercriminal actor claiming a large-scale data breach of the French fitness-chain L’Orange bleue and offering the allegedly exfiltrated member database for sale. The actor claims initial access to an individual club’s administration panel, followed by exploitation of a publicly accessible, unauthenticated IDOR-prone export endpoint. They allegedly automated extraction at approximately 200 requests per second, potentially accessing records beyond the originating club due to insufficient tenant/data segregation.
Allegedly breached the Belgian table-tennis organizations AFTT and FRBTT and offered approximately 1.69 GB of purportedly stolen member, user, fine, and club-administrator data for sale. The claim is explicitly unverified.
