Google security researchers have revealed this week that the immensely popular Fortnite Android app is vulnerable to so-called man-in-the-disk (MitD) attacks.

This vulnerability allows low-privileged malicious apps already installed on a users' phone to hijack the Fortnite app's installation process and install other malicious apps that have a higher permissions level.
