What happened

An actor known as ChimeraZ published a 3 MB CSV file with 15,732 entries linked to 8,656 customers of the French Chess Federation (FFE). Published samples include names, physical addresses, and transaction-related information. The data origin and whether a security breach occurred at FFE remain unconfirmed.

Why it matters

If confirmed, it exposes customer personal and transaction data, with risk of scams, targeted phishing, and fraud. FFE is the national governing body for chess in France. For now this is an unverified claim, with no proven impact.

What to do

Await an FFE statement and check whether your organization's records appear in the published sample. Warn customers about messages using real names and addresses. Do not treat it as a confirmed incident before verification.
