The world’s leading online hotel services are subject to massive hacking incidents and high-profile attacks to steal sensitive information. The compromised databases appear to contain full names, addresses, credit card information, national identification numbers, and other sensitive details.

The report, prepared by Website Planet, mentions that the logs were discovered after the detection of various AWS deployment failures, which could have affected up to 10 million users. This database, equivalent to about 25 GB, was exposed to any user who knows how to find it: “The database can be hacked by any malicious user with minimal knowledge of cloud storage,” the researchers note.

At the moment it is impossible to know exactly how many users have been affected by this incident, and it is also unknown whether the threat actors who have accessed this information used exploiting security vulnerabilities in Prestige Software systems. However, specialists mention that once users of these platforms record their personal data, this information is automatically uploaded to the Cloud Hospitality subscription to the AWS bucket, which could mean that the information of all users on this platform could have been compromised.
