While the US is worrying about hackers with the midterm elections growing closer, over in Brussels, another major breach was experienced by Tomorrowland. According to a report by Brussels Times, hackers were able to infiltrate the festival’s systems and obtain the data and personal information of 64,000 attendees.

If it’s any consolation, the information obtained was from those attending in 2014; additionally, no information such as payment credentials was taken. The information stolen included names, addresses, age, postcode and gender.

“The managers of the Paylogic ticketing system noticed some unusual activity on an older system,” spokesperson Debby Wilmsen told De Standaard. “After careful analysis it appeared that an old database from Tomorrowland 2014 was concerned. The server in question was immediately taken offline.”

Everyone effected by the breach will be informed of the incident by email. Users are advised to change their passwords as a general rule of safety.
