> iOS7 provides settings for "background app refresh". Disabling unnecessary app's background refreshing contributes to preventing the potential background monitoring. However, it can be bypassed. For example, an app can play music in the background without turning on its "background app refresh" switch. Thus a malicious app can disguise itself as a music app to conduct background monitoring.
Of course, the idea is that the app would actually do something useful, would do that useful thing correctly, and only activate the malicious code for targetted users (none of which would be Apple testers).
