Leaked Secrets and Unlimited Miles: Hacking the Largest Airline and Hotel Rewards Platform

Other

Between March 2023 and May 2023, we identified multiple security vulnerabilities within points.com, the backend provider for a significant portion of airline and hotel rewards programs. These vulnerabilities would have enabled an attacker to access sensitive customer account information, including names, billing addresses, redacted credit card details, emails, phone numbers, and transaction records. Moreover, the attacker could exploit these vulnerabilities to perform actions such as transferring points from customer accounts and gaining unauthorized access to a global administrator website. This unauthorized access would grant the attacker full permissions to issue reward points, manage rewards programs, oversee customer accounts, and execute various administrative functions.
