April 13 (Reuters) - Gym operator Basic-Fit has suffered a data breach ‌involving around 1 million members ‌with 200,000 in the Netherlands alone, a company ​spokesperson said on Monday.

Basic-Fit owns gyms serving over 4.5 million customers across six European countries including France, Germany, ‌and Spain. It ⁠also runs a franchise model in six other countries, which ⁠uses a separate system and was not affected by the leak.

• ​Breach involves ​members' bank account ​details, names, birth ‌dates and contact information

• Basic-Fit says the unauthorised access was detected by its system monitoring tools and was stopped within minutes

• Members whose data is ‌involved have been informed, ​Basic-Fit says

• The company ​noted it ​does not hold members' ‌identification documents and no ​passwords were ​accessed, adding that the main risk for affected members would be ​potential phishing ‌attempts
