TicketCounter.nl

In August 2020, the Dutch TicketCount Ticket Service accidentally published a backup copy of the database in a public place where it was then found and loaded in February 2021. The data contained 1.9 million unique email addresses, which were put up for sale at a hacker forum, as well as names, physical and IP addresses, gender, date of birth, the history of payments and, in some cases, bank account numbers. Later, the data were posted into open access.
