By identifying and manipulating these flaws in the logic, we can tamper with this detection allowing apps to run as expected on our modified devices.īy leveraging development flaws, we can bypass these checks and allow apps to run on modified devices However, the downfall to this is that most of these checks are done badly, perhaps the strings are hardcoded, the result relies on a single Boolean return value, or incorrect logic means the checks don’t even run at all. Developers add techniques into their app code to check whether this root user is accessible, whether the device has been modified, or if its possible to view files that are usually restricted and then take certain actions based on the result of these checks. To break out of the operating system ‘chains’ the device requires certain modifications, either through vendor approved unlocking, or device exploitation. Being the super user, this account can do anything, view, edit, modify anything but in the modern age when smartphones likely have more personal data than our other devices, being able to view any file is not always a good thing from a privacy perspective.
