More than 110 million people use PSN (Playstation's online gaming service, connected to the console), and while authorities have some reason to believe that the use of PS4 networks may be involved with the planning and undertaking of the attacks by ISIS, nothing has been confirmed as of right now -- which is important to remember.
But, the idea may seem novel in concept, though the application could be surprisingly easy, as the console provides multiple lines of of communication for users including text messaging, direct voice communication, and in-game means of sending messages. With the overall system being more primitive than other mainstream messaging services, it offers a unique opportunity for users to fly under the radar, undetected. And it's not as if governments and law enforcement agencies across the world are unaware of the possibility of real-life menace within online worlds, as the CIA and NSA both have infiltrated online games in the past in an effort to keep tabs on terrorist communication within online games like World of Warcraft. But, for agencies to even be able to monitor communications on these consoles (never mind the legality of it all), entire consoles would have to be tapped, totally -- which may not even be possible at this point, according to the Forbes' report.
