European gym chain Basic-Fit disclosed a breach affecting approximately 1 million members in April 2026. The exposed dataset includes bank/SEPA direct-debit details and fitness-profile data alongside standard contact details. Direct-debit account numbers in the wrong hands enable downstream fraud against the customer's bank account.
