Manchester Airports Group said on Thursday that a cyberattack by an unauthorised third party exposed information belonging to about 8.7 million customers of Manchester, London Stansted and East Midlands airports in the United Kingdom. The group operates the three airports and described the incident as a cyberattack on its systems.

The compromised data relates to bookings for car parking, lounges and fast-track services, as well as airport Wi-Fi sign-ups. According to a MAG spokesperson, the information taken includes email addresses, telephone numbers, vehicle registration numbers and postcodes.

MAG said no customer bank-account or payment-related information was affected. It also said the attack did not disrupt normal airport operations. The company has informed the relevant authorities and is working in coordination with them.
