So where does the Fortnite Installer come in and why is this all relevant? A Flaw in Fortnite’s Installation ProcessĮarlier today, Google disclosed a vulnerability they discovered with the first version of the Fortnite Installer. #Fortnite download samsung apk#But if you download an APK from XDA Labs, APKMirror, or other third-party sources, the standard package installer will handle the install and prompt the user to install that package. If you attempt to install an app from the Play Store or equivalent app store with the INSTALL_PACKAGES permission, it’ll silently handle the install all on its own without further user intervention after you start the download. In any case, that about sums up the difference between installing an app from an approved, first-party source and third-party source. I have observed this on the Honor Note 8 running EMUI 5 imported from China, though I’m sure other Chinese Huawei and Honor devices also have this feature in their Package Managers. OEMs can also customize the Package Manager: For instance, the Package Manager in the Chinese version of Huawei’s EMUI 5 has a feature to scan the APK to decide if it’s safe and control what permissions are granted before installation. If the user accepts, then the app is installed with the requested non-runtime permissions. Rather, it’ll prompt the user whether they want to install the app and list any sensitive permissions that it requests to be granted on install. However, the Package Manager doesn’t allow the app to be installed silently. Once installation from unknown sources is enabled either globally or specifically for a requesting application, then the user can side-load an app. Installing an app outside of the Play Store results in a prompt from the Package Manager. On Android Oreo, if an app without INSTALL_PACKAGES permission wants to install an app, it needs to be whitelisted to be able to send the request to the package installer.
