Breach: September 2024 · added to HIBP: 20 October 2026
Sources checked 27 October 2026. This is a dated account; later findings may change the picture.
Two dates, two different meanings
If you have just received an Assurance Retraite alert, the date is worth reading carefully. HIBP lists the incident as occurring in September 2024 and records its addition to the service on 20 October 2026. Those dates describe different events.
An alert generated when a dataset becomes searchable does not establish new access to your account in October. It tells you that historical information has now entered that source’s coverage. That difference matters when you decide what to do next.
What the published records describe
HIBP describes an incident affecting approximately 370,000 assistance beneficiaries, with about 70,400 unique email addresses. Its listed data classes include contact and identity information. Assurance Retraite’s original disclosure describes misuse of partner accounts on its PPAS portal.
Passwords are not among the data classes listed on HIBP’s Assurance Retraite page. It would therefore be inaccurate to describe that record as proof that your pension-account password was leaked. Nor should the overall beneficiary count be confused with the number of email addresses in HIBP.
What to check before changing anything
Read the official disclosure through Assurance Retraite’s website. Review any instructions intended for affected people. Be cautious with unexpected messages that mention a pension, identity check or account update and ask you to follow a link or provide more information.
If a password is reused, change it wherever you use it and save unique replacements in a trusted password manager. That is a response to password reuse, not a claim that every data breach contains passwords. Contact or identity exposure can require attention even without a password leak.
How to read this on our results page
The breach-dataset total counts datasets that contain the address. The password-dataset total counts only datasets whose listed data types include passwords. Neither number is a count of accounts currently controlled by an attacker.
Use the record’s breach date, source and data types together. If a company name is unfamiliar, do not invent a login or try a reset through an unverified website. Our help page explains how historical records, unknown collections and current account access differ.
Choose your next step
- Check whether your email appears in known breach datasets
- Check a password separately, using local hashing
- Learn how to check a suspicious breach message
- Work through official account recovery guides
Email checks require ownership verification. Dataset matches do not prove current account access or your exact password. Password checks cannot identify the account a password came from. This is guidance, not incident response or personalised legal advice.
