Kiassure
CriticalConfirmedInsurance
A claim published on September 27, 2026 on a cybercrime forum, under the alias "RedStone", announces the sale of a database attributed to Kiassure, a French wholesale broker specializing in health and pension insurance. The described dataset covers 42,742 client files and roughly 918 MB of data spread across CSV and JSON files, including names, postal addresses, emails, phone numbers, IBANs and contract-related information (contract numbers, premiums, coverage). Kiassure has not issued any public statement on the incident as of this writing; several specialized cybersecurity outlets have reported and partly corroborated the claim.
The combination of identity, contact details and IBAN could allow a third party to run targeted phishing attempts impersonating Kiassure, a broker or an insurer.

What you can do
- Expect phishing attempts quoting your name and this company. A message that knows your details is not legitimate for that reason.
- Watch your statements. On any unknown debit, block the card and request a refund — French law (art. L133-18) entitles you to it.
- You can ask the organisation exactly what was exposed about you (right of access), and complain to the DPA if no answer comes within a month.
