## French Cadastral Data Server Allegedly Breached, 2 Million Property Holders Exposed and Access Still Claimed

The group posting as **ZeroBytes** claims a second intrusion at France's **Direction générale des Finances publiques**, this time against the professional cadastral data server that holds land and property registry information. They describe **252,149 extracted rows** covering **2,041,778 individuals**, since each row can list several property holders, and estimate that around **20 million citizens** were reachable through the system although extraction was never completed. Access is attributed to **valid credentials combined with a multi factor authentication bypass**, with no VPN required. The actors state they **remain logged in** and are offering that access for sale alongside the data. The claim is **unverified**.

### ⚠Potential impact

Cadastral records establish **who owns which property and where it is**, which links named individuals to real assets at fixed addresses. That supports wealth profiling and physical targeting in a way ordinary contact data does not, and because several holders can appear against one parcel, it also exposes **family and co ownership relationships**. The more urgent element is the claim of **continuing access**. If accurate, the exposure is not bounded by the 252,149 rows taken so far, and the actors state the constraint was extraction effort rather than any control stopping them. A multi factor bypass would indicate the authentication layer did not hold.

### iStatus

Unverified 

This is the **second claim against the same French tax authority from this group in two days**. The 20 million figure is their estimate of what was reachable, not what was taken, and should not be read as a record count. A sample is hosted across three mirrors, which **Dark Web Informer is not reproducing** along with the contact channels. The assertion that the intrusion has gone **publicly unacknowledged** is the actors' own and is uncorroborated. The claim is **unverified** and the DGFiP has not publicly addressed it.
