European hotel booking platform provider Gekko Group mistakenly stored over 1 terabyte of information on a publicly configured server, exposing troves of data related to its hotel B2B clients, as well as travel agents and their customers. The majority of the exposed data was collected by Gekko brands Teldar Travel, which provides a booking system for travel agents, and Infinite Hotel, a distribution specialist that provides an inventory of hotels to B2B clients.
