Manchester Airports Group (MAG) confirmed a major cyberattack impacting Manchester, London Stansted, and East Midlands airports. The breach exposed the personal information of approximately 8.7 million customers, including email addresses, phone numbers, vehicle registration numbers, and postcodes related to car park, lounge, and Fast Track bookings, as well as Wi-Fi users.

MAG stated that no bank or payment details were compromised, as the group does not hold such information. While airport operations continued normally, the ‘Manage My Booking’ service at Stansted was temporarily suspended. The company advised affected customers to remain vigilant against suspicious communications.

Recent reports confirm that for the vast majority of affected customers, only email addresses were compromised. MAG has emphasized that passenger safety and aviation security remain uncompromised, and the company is contacting affected individuals directly. The group is currently working with specialist advisors and relevant authorities to manage the incident.
