Twizzit
HighReportedNonprofits
A database attributed to Twizzit, a Belgian platform for managing sports clubs, associations and federations, is being offered for sale on a specialized leak forum by an actor using the pseudonym RedStone. The claim covers information on more than 1.5 million unique members, spread across more than 178,000 groups and 5,500 organizations, mainly in Belgium, as well as in France and the Netherlands. The announced data includes names, email addresses, phone numbers, profile photos and affiliation details to clubs, groups and sporting seasons. Twizzit has not publicly confirmed the claim to date.
Linking a person to a specific club, team or role, combined with their contact details, could facilitate targeted phishing attempts, particularly against minors present in the youth movements affected.

You are only affected if you had an account or an order with this organisation.
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.
