By default, the UWP-programs have access to files and folders located in the root folder of the installed application and data folders in AppDataLocal, AppDataRoaming, and Temp. If the service requires access to files outside of these folders, developers can request the necessary permissions.

According to Lutyens, because of a bug in Windows 10, users could not see the settings window in which they need to give applications permission to access the file system. This allowed the attackers to install on victims ‘ computers viruses and steal personal data from infected devices.
