Discount Indonesian Airline Lion Air Suffers Massive Data Breach – 35 Million Passenger Records Exposed
Personal data of 35 million passengers from two Lion Air subsidiaries was dumped onto online data exchanges. Data from Lion Air subsidiaries, Malindo Air and Thai Lion Air, was leaked online since about mid-August. The sensitive data includes passport details, home addresses, and phone numbers.
It is believed that the passenger data was hacked from a Lion Air Amazon Web Services Inc (AWS) server. The personal data of passengers who flew with Thai Lion Air and Malindo Air were uploaded and stored in an open Amazon Web Services cloud storage bucket that was not protected.
Four databases of hacked passenger data were found in online in data exchange forums. Two files belong to Malindo Airlines and another two belong to Thai Lion Air were all dumped online in a directory created in 2019 May. The databases include 21 million records and 14 million for Malindo Air and Thai Lion Air, respectively. The data has been circulating on exchange forums since 2019 August 10.
The data was posted in instant messaging service Telegram, as well as on cloud storage and file-hosting services mega.nz and openload.cc. Both sites still have an active link to the databases.
Hacked data includes passenger and reservation IDs, physical addresses, phone numbers, email addresses, passenger names, birthdates, phone numbers, passport numbers, and passport expiration dates. No payment information was breached.
