# La France insoumise

Data breach — Moderate

An individual claims to have published a partial database attributed to the La France insoumise website, about 544 MB with 1,270,096 records (1,165,256 unique lines by their count). The samples shown reportedly relate mainly to door-to-door canvassing, election campaigns and activist events. They would include addresses and housing references, GPS coordinates, internal identifiers, contact details, and pseudonyms or names of activists. FrenchBreaches also mentions flaws that reportedly let insufficiently controlled activist accounts access internal data, and a calendar reachable without login that reportedly exposed over 5,000 phone numbers and 900 email addresses. The number of records does not necessarily match the number of people affected, and the figures have not been independently verified.

Housing addresses combined with contact details and activist names or pseudonyms could allow a third party to locate or contact targeted individuals.

## Exposed data

- Postal address
- Customer ID
- Full name
- Phone number
- Email address
- 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.
