Credit Card Numbers For Millions of Hotel Guests Exposed By Misconfigured Cloud Database


    “A widely used hotel reservation platform has exposed 10 million files related to guests at various hotels around the world, thanks to a misconfigured Amazon Web Services S3 bucket,” reports Threatpost. “The records include sensitive data, including credit-card details.” Prestige Software’s “Cloud Hospitality” is used by hotels to integrate their reservation systems with online booking websites like Expedia and The incident has affected 24.4 GB worth of data in total, according to the security team at Website Planet, which uncovered the bucket. Many of the records contain data for multiple hotel guests that were grouped together on a single reservation; thus, the number of people exposed is likely well over the 10 million, researchers said. Some of the records go back to 2013, the team determined — but the bucket was still “live” and in use when it was discovered this month. “The company was storing years of credit-card data from hotel guests and travel agents without any protection in place, putting millions of people at risk of fraud and online attacks,” according to the firm, in a recent notice on the issue. “The S3 bucket contained over 180,000 records from August 2020 alone….” The records contain a raft of information, Website Planet said, including full names, email addresses, national ID numbers and phone numbers of hotel guests; card numbers, cardholder names, CVVs and expiration dates; and reservation details, such as the total cost of hotel reservations, reservation number, dates of a stay, special requests made by guests, number of people, guest names and more. The exposure affects a wide number of platforms, with data related to reservations made through Amadeus,, Expedia,, Hotelbeds, Omnibees, Sabre and more…. A too-large percentage of cloud databases containing highly sensitive information are publicly available, an analysis in September found. The study from Comparitch showed that 6 percent of all Google Cloud buckets are misconfigured and left open to the public internet, for anyone to access their contents.
