UPDATE, 11.48am — Thousands of Aussies could have had their private info accessed in the Ticketmaster hack.

News Ltd tech editor Jen Dudley-Nicholson has told Leon Byner:

“It isn’t just sporting matches… Ticketmaster sell musical tickets and concerts and all sorts of things. They’re one of the world’s major events organisations. It could’ve affected thousands of Australians.

“Worst case scenario it could mean that somebody else has your credit card details… and if you’ve used Ticketmaster since September last year you really need to go in today, log in to your account, change your password, make sure it’s all locked down.”

Global ticketing giant Ticketmaster has advised some of its customers may have had their personal or payment information accessed by “an unknown third-party”.

Up to 40,000 UK customers are believed to have been affected, while “international customers who purchased, or attempted to purchase, tickets between September 2017 and June 23, 2018” may have been affected.

“If you have not received an email, we do not believe you have been affected by this security incident based on our investigations,” Ticketmaster said in a statement.

According to the company:

“On Saturday, June 23, 2018, Ticketmaster UK identified malicious software on a customer support product hosted by Inbenta Technologies, an external third-party supplier to Ticketmaster.

“As soon as we discovered the malicious software, we disabled the Inbenta product across all Ticketmaster websites.

“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.”
