A hack attack against an Irish loyalty programme firm, Loyaltybuild, has led to the theft of the full credit card details of at least 376,000 consumers, says the country’s data protection watchdog.According to the results of a preliminary investigation by the Office of the Data Protection Commissioner (ODPC), credit card and – contrary to all payment storage rules – CVV details were held unencrypted on Loyaltybuild’s systems in the run-up to attacks in the middle of October.
