Tech Crunch has reported that a recently found Air India passenger data breach indicates that the SITA hack is worse than first anticipated. Three months after air transport data giant SITA reported its own data breach, the damage is still mounting. Air India said this week that personal data of about 4.5 million passengers had been compromised following the security incident at SITA, the data processor for the airline. The stolen information included passengers’ name, date of birth, contact information, credit card details as well as passport and ticket information and Star Alliance/Air India frequent flyer data, Air India said in a statement. Luckily, the company said that CVV/CVC data of credit cards were not held by SITA. Though Air India has urged passengers to change passwords “wherever applicable to ensure safety of their personal data.”
