The Department of Home Affairs says it is working with Ticketmaster to investigate a recent cybersecurity incident. 

Reports indicate that the hacker group ShinyHunters has stolen personal information belonging to Ticketmaster customers.

According to CyberDaily, the breach involves the personal details of approximately 560 million Ticketmaster customers. 

The stolen data, which reportedly includes names, addresses, credit card numbers, phone numbers, and payment details, is being sold for US$500,000 by the hacker group.

This incident is not the first involving Australian consumers and ShinyHunters. In September last year, the hacker group allegedly accessed the personal information of 193,000 Pizza Hut customers.

The timing of this breach is particularly significant, as it follows closely on the heels of a major lawsuit filed against Live Nation, Ticketmaster's parent company, by the US Department of Justice (DOJ). 

The DOJ has accused Live Nation of operating an illegal live event monopoly, alleging that its market dominance has led to increased ticket prices and reduced competition. 

Live Nation and Ticketmaster merged in 2009 to form Live Nation Entertainment, creating a global powerhouse in live music, sports, and theatre ticketing.

As the investigation into the Ticketmaster breach continues, customers are advised to monitor their accounts for any suspicious activity and to take proactive steps to secure their personal information.
