Ticketmaster has informed its Irish customers about a potential security breach compromising payment details.

The ticketing service says malicious software was found on a customer support product which was hosted by an external third-party supplier on the 23rd of June.

In an email to customers, they say anyone who purchased or tried to purchase tickets on the site between February and June of this year could potentially be affected.

Ticketmaster says they're working with all the relevant bodies, while all notified customers have been asked to change their passwords in the next 24 hours.
