Terrorists could be using the Sony PlayStation 4 games console to communicate with each other because it is so hard to monitor, according to Jan Jambon, Belgium's Minister of the Interior.
"The most difficult communication between these terrorists is the PlayStation 4," said Jambon. "It's very difficult for our services – not only our Belgian service but international services – to decrypt the communications via PlayStation 4."
Jambon was speaking at an event organised by news outlet Politico on November 10th, three days before the terror attacks in Paris which killed at least 129 people and left hundreds injured.
The perpetrators are believed to have been based in Belgium, and a Reuters' source claims the attack was planned by a Belgian national.
At the Politico event, Jambon added that messaging service WhatsApp is also very difficult to monitor, but intelligence services are able to decrypt these communications.
There are around 65 million active users on the PlayStation Network, which allows users to send messages to one another and talk to other players in multiplayer games. Sony has sold around 25 million consoles since it was launched two years ago.
This is not the first time the PlayStation has been linked to terrorism. In May, a 14-year old Austrian boy who had downloaded bomb-building plans onto his console received a two-year custodial sentence on terrorism charges.
Sony had not responded to requests for comment at the time of publication.
