7,665 patients affected by a claimed data leak at Asten Santé

On 5 February 2026, Asten Santé — a French provider of home-based healthcare services (prestataire de santé à domicile) — was named in a data-leak claim posted to a cybercrime forum by a threat actor using the handle sux1337. The actor advertised a dataset said to contain 7,665 lines of patient records and made the data available for free rather than for sale.

According to the claim, the exposed data related to the company's patients. For a home-healthcare provider, such records typically combine identity, contact, and care-related details, making the leak sensitive even where strictly clinical information is limited.

Categories of data reportedly affected:

• Patient identity details (names)
• Contact information
• Patient/care-related administrative data

Shortly after the claim, Asten Santé temporarily suspended access to its patient and prescriber extranet portals for security reasons while technical teams worked to restore service, and made customer-relations staff available to handle inquiries. The full scope of the compromise and the attack vector were not publicly confirmed, and the status of the incident remains unclear.
