App security flaw makes your iPhone call without asking
If you're an iPhone user, you may want to be cautious about opening messages that contain phone numbers in the near future; they may cost you a lot of money. Developer Andrei Neculaesei notes that maliciously coded links in some apps will abuse the "tel" web handler (which covers dialing) to automatically make a phone call the moment you view a message. Potentially, an evildoer could force you to call an expensive toll number before you've had a chance to hang up. The exploit isn't limited to any one app or developer, either. Facebook Messenger, Gmail and Google+ all fall prey to the attack, and it's likely that other, less recognizable apps exhibit similar behavior. Apple's Safari browser will ask you before starting a call, but FaceTime's behavior lets you pull a similar (though not directly related) stunt.
