23,535 locum doctors - claimed data leak at Médecins Remplaçants

On 31 January 2026, a dataset described as the 2026 directory of French locum (replacement) doctors — "Médecins Remplaçants" — was advertised on the cybercrime marketplace BreachForums, where a seller claimed to be distributing the file. The listing was first flagged by the French breach tracker Fuites Infos.

The advertised file reportedly contains around 23,535 rows, each presented as a French locum physician with enough detail to identify and directly contact them. The source of the underlying data and how it was obtained were not disclosed; at this stage it is an unverified claim rather than a confirmed breach attributable to a specific organisation.

According to the listing, the exposed fields include:

• Identity: full name (first and last)
• Contact details: email address, landline and mobile phone numbers
• Administrative data: medical practice-authorisation number and its start-of-validity date
• Location: postal code and locality / zone identifier

If accurate, this combination of professional identifiers and contact data could facilitate targeted solicitation, phishing or impersonation, particularly when cross-referenced with other sources. As of the report the claim remained unverified, no affected entity had confirmed an incident, and no scope of impact had been independently established.
