Thousands of Ticketmaster customers across Australia and New Zealand are being warned to check their bank accounts following a cyber attack on the ticket seller's operations in Britain.
Data belonging to 40,000 people who bought tickets to events using Ticketmasters' UK website may have been accessed as a result of malicious software used in a customer support product supplied by another company.
A spokesman for Ticketmaster said emails were being sent on Thursday to customers in Australia and New Zealand who bought or attempted to buy tickets between September last year and February, warning them to check their bank accounts for any irregularities.
"There are no confirmed incidents outside the UK," he told AAP.
"However out of precaution we have approached customers in a number of territories, which includes Australia and New Zealand.
"We have no reason to believe they have been affected here in Australia or New Zealand."
Ticketmaster UK discovered last Saturday malicious software had been embedded in a customer support product hosted by Inbenta Technologies and that some customers' personal or payment information had been accessed by an unknown hacker.
"As a result of Inbenta's product running on Ticketmaster International websites, some of our customers' personal or payment information may have been accessed by an unknown third-party," the company said in a statement.
"Forensic teams and security experts are working around the clock to understand how the data was compromised.
"We are working with relevant authorities, as well as credit card companies and banks."
Less than five per cent of Ticketmaster's global customer base is thought to have been affected by the cyber attack.
