Little Snitch - makes these Internet connections visible and puts you back in control!

As soon as you’re connected to the Internet, applications can potentially send whatever they want to wherever they want. Most often they do this to your benefit. But sometimes, like in case of tracking software, trojans or other malware, they don’t.

But you don’t notice anything, because all of this happens invisibly under the hood.
