# Greffe du tribunal des activités économiques de Paris

Data breach — High

On 17 September 2026, an individual using the alias "Alduin" claimed on a cybercriminal forum to have leaked four files extracted from the website of the Paris Economic Activities Court Registry (Greffe du TAE de Paris). The data reportedly concerns judges, magistrates, court clerks and other people linked to the tribunal: names, email addresses, phone numbers, postal addresses, dates of birth, login identifiers and professional information (roles, chambers, terms of office). Independent analyses by different outlets estimate the number of distinct individuals affected at roughly 722 to 902. The Paris TAE Registry has not publicly confirmed the claim at this stage.

The disclosure of personal postal addresses and phone numbers of magistrates and judges exposes them to a risk of unsolicited contact, harassment or targeting linked to their judicial role.

## Exposed data

- Full name
- Email address
- Phone number
- Postal address
- Date of birth
- Customer ID
- 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.
