# Parti communiste français (PCF)

Data breach — Moderate

The French Communist Party (PCF) confirmed in a press release dated 23 October 2026 a leak affecting its file of members and supporters. The party states it was alerted the same day by ANSSI, started securing its systems, notified the CNIL and plans to file a complaint. The file reviewed by FrenchBreaches contains names, postal addresses, phone numbers and email addresses; the outlet estimates roughly 190,000 distinct people are affected, but this is an independent estimate rather than an official figure. The origin and exact scope of the leak are still under investigation.

The data links personal contact details to a presumed connection with a political party, which can be used for targeted solicitation, phishing or harassment.

## Exposed 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.
