Not properly verifying the server certificate on SSL/TLS may allow apps to connect to an imposter site, while fooling the user into thinking that the user is connected to an intended site. One example of associated risks is that this could expose a user's sensitive data.

Automated Detection
It is possible to automatically detect whether an application uses one of the three Android SDK packages named for establishing network connections, and to check if any of the methods from those classes are overriden by the application. It is not feasible to automatically determine the intent of the app or the environment the apps are used in.
