Bank says it already informed Ticketmaster about fraud at the beginning of April

The British bank Monzo warned Ticketmaster at the beginning of April about striking transactions that may have indicated a data breach. After an investigation, the bank claims to have been convinced at the time that there was a data breach.

On Friday, April 6, Monzo received fifty reports of fraudulent transactions with their bank card. After analysis, the majority of those tickets appeared to have been used at Ticketmaster between December 2017 and April 2018. The bank adapted its systems to recognize similar fraud and immediately block cards. Monzo also contacted the authorities and other banks, who, however, had not identified any similar cases.

In the days that followed, Monzo encountered more cases of fraud involving tickets at Ticketmaster, and on April 12, the bank’s security team visited Ticketmaster to share their collected information. The ticket company said it was investigating the matter.

In a subsequent fraud attempt, Monzo discovered that the criminals entered an incorrect expiration date. The customer had previously accidentally entered that same date at Ticketmaster. The bank then claims to have become convinced that there was a data breach at Ticketmaster. However, that company told Monzo on April 19 that internal investigations had revealed no irregularities.

On Thursday, Ticketmaster UK announced that some of its international customers who purchased or attempted to purchase tickets between September 2017 and 23 June 2018 had been subject to a data breach.
