# Réassurez-moi

Data breach — Moderate

Réassurez-moi, an online insurance broker, notified affected individuals that a third party gained unauthorized access to one of its tools, resulting in the exfiltration of personal data on September 13, 2026. Potentially affected information includes postal addresses, emails, phone numbers, family and professional situation, details related to insurance quote or financing requests (lending bank, loan amount and interest rate), and some connection and browsing data. The company states no banking data was compromised, though the exact information exposed varies by individual.

The combination of accurate contact details with precise information about a loan, quote, or insurance contract can make targeted phishing attempts impersonating an insurer more credible.

## Exposed data

- Email address
- Phone number
- Postal address
- Employment data
- Connection data (IP, logs)
- Other personal data

## 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.
- 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.
