Banks have issued new credit cards to tens of thousands of Ticketmaster customers following the high-profile cyberattack on the company in the summer.

Lloyds Bank, Halifax and Bank of Scotland are among the institutions that have dispatched new cards over fears personal details and payment information has been compromised.

According to the Daily Telegraph newspaper, affected customers are being notified by letter. They have been warned their existing card is to be blocked from October 15 with a replacement being issued within five working days. This means customers may be without their credit card for up to a week.

Up to 40,000 UK Ticketmaster customers were believed to have had “some personal or payment information” stolen following the data security breach earlier this year.

Ticketmaster admitted it had been hacked by “malicious software” on third-party customer support product Inbenta Technologies. Ticketmaster said the breach was likely to have only affected UK customers who purchased or attempted to purchase tickets between February and June 23, 2018.

Cybersecurity firm RiskIQ reported in August that the attack was not an isolated incident, as a hacking group called Magecart had targeted around 800 e-commerce sites.
