According to Tech Crunch specialists, some of the apps available on the App Store take both screen pictures as well as button usage data without the knowledge of their users. The guilty apps are the ones that use analytical tools made by the Glassbox company. Those tools put special programming code into the infected app that then infects the smartphone the app is installed on; it then sends data it gathers back to the app’s publisher. Not only are these informations collected illegally, as the companies using Glassbox do not inform their users about it in the user’s agreement but, according to Tech Crunch, they do not protect the collected data, meaning it can be easily stolen by the third party hackers. Wonderful.
