Data breach — Moderate

On 5 October 2026, an actor claimed a breach of Réussir, an agricultural news portal, which they date to September 2026. The dataset is said to contain over 3.3 million rows of records, not that many distinct individuals. It reportedly includes about 215,000 user accounts (names, usernames, e-mail addresses, phone numbers, creation and login dates, hashed passwords), two address files of about one million rows each (names, company names, postal addresses, phone numbers, e-mail addresses of agricultural professionals and farms) and a file of about one million rows on subscriptions. The claimed method, an authentication bypass through SQL injection, is unconfirmed.

The combination of identities, farm details, contact data and subscription information would allow a third party to run targeted phishing campaigns impersonating a publication, supplier or professional body in the agricultural sector.

## Exposed data

- Full name
- Customer ID
- Email address
- Phone number
- Postal address
- Connection data (IP, logs)
- Employment data
- Order history
- Password (hashed)

## What you can do

- Change that password — and everywhere you reused it. That is how a leak spreads to your other accounts.
- Turn on two-factor authentication on the affected accounts: a stolen password is then no longer enough.
- 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.
