Sabre first announced the data breach in May. Since then, the company said it has been working with its customers and partners that use or interact with the system. Some TMCs and travel agencies who may have booked affected travelers have also been notified about the incident, but Sabre said they do "not use or interact with the Sabre SynXis system." According to Sabre, there was "no indication" that other systems outside of SynXis Central Reservations were affected. They did, however, find that the unauthorized party accessed the information over the course of seven months, from August 2016 to March 2017. About 36,000 hotels use the SynXis reservations system.
