There are many things that tie BlackBerry users together, and one of those has always been the importance of security. Some people forget that being secure means more than just ensuring an application is virus free! Nefarious (what a great word) applications can access private data, sneak that data out to private websites, and even monitor your device traffic to keep tabs on what your doing all without the user knowing. Real dangerous applications can go even farther, allowing a developer to remotely execute code on a users device without the users permission! Imagine, applications that can decide what you can and can’t do, search the internet for things without you knowing or perform actions on your phone without your knowledge.
Not only are these security concerns very real, but they go unnoticed by all major platforms during testing and validation cycles. No major device manufacturer at this time is monitoring applications submitted to their platforms for what data is being sent and received. Although, to give them credit, BlackBerry has done a fantastic job of limiting what applications with back-doors can do.
