Ticketmaster has suffered two major data breaches: a 2018 Magecart attack that exposed financial details of 9.4 million European customers, and a 2024 attack via its Snowflake cloud environment that exposed data on approximately 560 million customers globally. The UK ICO fined Ticketmaster UK £1.25 million over the 2018 breach.
⚖️ Regulatory action: Ticketmaster UK was fined £1.25 million by the UK ICO in November 2020 for the 2018 breach. The 2024 Snowflake breach is subject to ongoing regulatory review.
The hacking group ShinyHunters obtained credentials via infostealer malware and used them to access Ticketmaster's data held in a Snowflake cloud environment, exfiltrating approximately 1.3 terabytes of data between April and May 2024. The stolen dataset — put up for sale on a dark-web forum in late May 2024 — included names, addresses, phone numbers, partial payment card details, and ticket purchase history for hundreds of millions of customers.
Malicious code was injected into a third-party chatbot embedded on Ticketmaster's payment pages, allowing attackers to skim names and payment card details in real time. The ICO found Ticketmaster failed to act promptly after being alerted to suspicious activity by its bank.
If you have ever purchased tickets through Ticketmaster, your personal and financial data may have been exposed in one or both breaches. A GDPR subject access request reveals exactly what Ticketmaster holds, how long they retain it, and whether it has been shared with third parties.
