How to detect XCode Ghost

With NetworkToolbox and the new connections tool, it is relatively easy to detect Apps that are containing the so called XCode Ghost code.

For this, similar to the general explanation, just start NetworkToolbox and open the Connections tool.

The screen is divided into three different sections. The first, External TCP connections is the interesting one. The number on the right side of this line shows the number of connections. If there are too many (maybe more than five), just wait a while and press the refresh button at the top until this number decreases to less then five.

As you can see, there is the suspicious domain This proves that this App “calls home” to that domain and is “infected”
