Air India's passenger service system provider SITA faced a sophisticated cyberattack in February leading to leak of personal data of certain number of the national carrier's flyers, an official statement said on Friday.

Personal data -- including name, date of birth, contact information, passport information, ticket information and credit card data -- which was registered between August 11, 2011, and February 3, 2021, has been leaked of a certain number of Air India's passengers, the statement issued by the airline said.
