Genius, an Android app-based cash register built by French postal service La Poste, leaked more than 23 million records. 

Noam Rotem and Ran Locar, vpnMentor’s research team, found the database belonging to Genius, which integrates many different processes to help small business owners. According to the vpnMentor report, La Poste is the main postal service in France, majority-owned by the French government, and also operating in overseas territories traditionally linked with the country. It’s the second-largest employer in France. Their operations include insurance, banking, webmail hosting and many more services for private citizens. 

The company also offers services for small-to-medium businesses (SMBs) in France. Genius also assists SMBs with inventory management, data reporting and analytics, accounting and many more key processes. 

Upon identifying La Poste as the database’s owner, the research team reached out to them, their hosting company and The Commission nationale de l’informatique et des libertés (CNIL), France’s independent regulatory body for data privacy. The database was closed almost 3 weeks after the researcher's first contact with the French CNIL. 

According to the researchers, they found more than 15 GB of sensitive information, with 23 million records originating from SMBs across France, Belgium, Switzerland, Italy, Spain and maybe more. Entries into the database were linked to payments made by customers via Genius, as well as other functions carried out on the app. Each entry contained different forms of data, depending on the action being taken by the user. These included Personally Identifiable Information (PII) data of both the Genius users and customers, along with PII about the businesses’ finances and operations. 

Examples of the user data viewable of the database included:

• Full names, Email addresses, phone numbers, and Dates Of Birth, of people using the app.
• City of business residence and zip codes of users.
• Information about products sold (label, price, barcode, etc) and transactions made via Genius.
• Information about sellers (name, email, phone number).
• Bills sent to customers and suppliers
• Business’ Stock inventory
• Both the test and genuine values of products on Genius.
• Email addresses of customers who received a bill via Genius.
• Total values of the business’ transactions made via Genius.
• Business’ Siret number (for French business registration)
• Much more
