Last month Ticketmaster got hacked by a group known as ShinyHunters, the same group that previously stole data containing details of 70 million AT&T customers.
They got their hands on the personal details of 560 million Ticketmaster customers, with the intention of selling the purloined data onwards for half a million dollars. Apparently the information included at least partial credit card numbers and ticket sales.
No-one, nothing, is safe out there. I guess we all have to operate on the basis of if we enter our data anywhere online then there’s a non-zero chance it’ll be expropriated by bad actors at some point.
