Fraud at United and American Airlines

Ten thousand American Airlines, and three dozen United Airlines, accounts were targets of fraud, with criminals reusing credentials to access customer loyalty reward points and use them to book or upgrade flights late last month, according to recent reports.

The loyalty program accounts breach, American’s AAdvantage and United’s MileagePlus, is reminiscent of a similar attack against Hilton’s Honor app that logged loyalty points whenever a customer booked a Hilton hotel room. While credit card numbers weren’t stolen in the airline incident, credit cards tied to Hilton accounts were sometimes used to buy even more reward points after existing points were exhausted.
