Yesterday on May 29, 2024, news broke of an alleged data breach involving Ticketmaster, a prominent ticket sales and distribution company. Ticketmaster has confirmed unauthorized activity within a third-party cloud database environment, claiming to have exposed the personal information of over 500 million customers. This breach includes sensitive data such as emails, phone numbers, addresses, and financial details.

ShinyHunters, a notorious attacker, reposted the breach . According to reports, the data from this breach has been put up for sale for a $500.000 asking price on BreachForums, a site previously taken down by the FBI but has since resurfaced. This development is concerning, considering the extensive amount of data allegedly compromised.

The data allegedly includes:

  • 560 million full customer details (including names, addresses, emails, phone numbers, and potentially more)

  • Ticket sales, event info, and order details

  • Credit card details, some including customer name, last 4 digits of the cards, and expiration dates

  • Customer fraud details

  • ... and more

Legal and Official Responses

The Australian Home Affairs Department has confirmed a cyber incident impacting Ticketmaster customers. Additionally, an antitrust complaint was filed against Ticketmaster and Live Nation in California on May 23, 2024, further complicating the situation for the company.

Historical Context: Magecart Attack

This isn't the first time Ticketmaster has faced a significant data breach. Previously, the company was attacked by the Magecart group, a notorious cybercriminal collective known for their innovative and damaging tactics. In the Magecart attack, the group infiltrated Ticketmaster's supply chain by injecting malicious code into third-party software used by the company. This code silently captured payment information entered by customers on Ticketmaster's website, redirecting it to the attackers.

Such incidents highlight the vulnerabilities in online ticketing systems, particularly within the supply chain and client-side components. Attackers often exploit these overlooked areas, leading to significant data breaches.

Attack Vector

Ticketmaster confirmed that the breach occurred through unauthorized access to a third-party cloud database provider, Snowflake.
