38M Records Revealed Online – Includes Tracking Information


More than a thousands of web apps mistakenly unlocked 38 million records on the open internet, including data from multiple Covid-19 contact tracking platforms, vaccination sign-ups, job application portals, and employee databases. The data comes with a wide range of sensitive information, from people’s phone numbers and home addresses to social security numbers and Covid-19 vaccination status.

The incident affected major companies and organizations, including American Airlines, Ford, transportation and logistics company JB Hunt, the Maryland Department of Health, the New York City Municipal Transportation Authority, and public schools in New York City. And while data revelations have since responded, they show how a poor configuration setting on a popular platform can have a lot of impact.

The disclosed data is all stored on Microsoft’s Power Apps portal service, an enhancement platform designed to easily create web or mobile apps for external use. If you need to immediately rotate a site to sign up for a vaccination appointment in time, as, a pandemic, Power Apps portals can be created in front of the public site and the backend to manage data.

Beginning in May, researchers from security firm Upguard began inspection a large number of Power Apps portals have publicly disclosed data that was supposed to be private – including some Power Apps created by Microsoft for its own purposes. None of the data is known to have been compromised, but the finding is still important, as it reveals the management of the Power Apps portals scheme has already recovered.

In addition to managing internal databases and offering a foundation to create apps, the Power Apps platform also provides ready -made applications an application interface to communicate with data. Although Upguard researchers know that when these APIs are enabled, the platform is made the default so that the corresponding data can be publicly accessed. Enabling privacy settings is a manual process. As a result, many customers misconfigure their apps by leaving an uncertain default.

“We found one of these misconfigures to expose the data and we thought, we haven’t heard of it yet, is it just one thing or is it a systemic issue?” says Greg Pollock, vice president of cyber research at UpGuard. “Because of the way the product works on Power Apps portals, it’s very easy to do a survey. And we discovered that there were tons of it exposed. It’s wild. ”

The differences in information encountered by the researchers are very wide. JB Hunt’s disclosure is data on job applicants with social security numbers. And Microsoft itself has opened up a number of databases of its own Power Apps portals, including an old platform called “Global Payroll Services,” two portals called “Business Support Tools “, and a” Customer Insights “portal.

Information is limited in many ways. The fact that the state of Indiana, for example, has exposure to the Power Apps portal does not mean that all data held by the state is disclosed. Only a portion of the contact tracking data used by the state’s Power Apps portal is included.

An incorrect configuration of cloud-based databases turned out to be a serious issue over the years, revealed a lot of data of improper access or theft. Many cloud companies like Amazon Web Services, Google Cloud Platform, and Microsoft Azure are all there took steps keeping customers ’data private by default from the start and flagging potential configuration errors, but the industry has not prioritized the issue to date.

After years of studying cloud configuration errors and data disclosure, Upguard researchers were shocked to discover issues with a platform they hadn’t seen before. Upguard tries to survey the exposures and notify as many affected organizations as possible. Researchers can’t go to every entity, though, because there are many, so they also reveal what Microsoft knows. At the beginning of August, Microsoft Office has partnered those Power Apps portals now default to API data storage and other private information. The company too releases a tool can be used by customers to check their portal settings. Microsoft did not respond to a request from WIRED for comment.
