+## Security warning
+
+- ### Don't run Fether as root
+- ### Beware of suspicious symlinks called fether-x.y.z-x86_64.AppImage.home
+This attack vector applies to any AppImage application. It consists of crafting a .home file/folder to be used as the home folder by an AppImage application. The danger resides in the fact that this .home file could be a symlink somewhere on the user's computer. The AppImage would be using this new location as a home folder, in a non-transparent way. Running the application as root might damage a system, for example, by overflowing the /boot partition.
