# CGT de l'Aude (structures syndicales, dont l'Union locale de Carcassonne)

Data breach — Moderate

A file linked to CGT union structures in the Aude département is claimed by a hacking group. It contains nearly 77,000 lines; after deduplication, about 4,600 distinct people appear in it, mostly in the Aude. The records include names, postal addresses and, for some, phone numbers and email addresses, along with the local union or professional sector they are attached to. The method of access and the compromised system have not been independently confirmed. The file does not establish each person's status (member, officer or contact), nor whether the contact details are personal or professional.

These contact details and the union affiliation could let a malicious third party target the people concerned by message, call or mail, including phishing attempts.

| Accounts affected | 4,600 |

## Exposed data

- Full name
- Postal address
- Phone number
- Email address
- Employment 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.
