Excessive Permissions
Data security is a priority for many people, but even amongst them, mobile applications often aren’t even considered a potential threat to their data. While you should ever only download applications from an official application store, some attacks can potentially slip through the vetting process to be distributed via these means. Therefore, it is important to carefully consider every application you have installed and the permissions that each one demands. If these permissions seem excessive for the application’s needs, reconsider if the app is necessary to use (chances are, it isn’t). This helps protect you against the tactic that many cybercriminals use: getting a harmless app to the store, and then turning it malicious with an update once it is downloaded.
