2024-08-06 , Florentine E

Since we were children we wanted to go to the arcade and play for hours and hours for free. How about we do it now? In this talk I’m gonna show you some vulnerabilities that I discovered in the cashless system of one of the biggest companies in the world, with over 2,300 installations across 70 countries, from arcades in Brazil, amusement parks in the United Arab Emirates to a famous roller coaster in Las Vegas. We will talk about API security, access control and NFC among other things.
