This news broke three days ago, but got very little, if any, coverage on NZ media:

Hack takes down French TV network

"The French government is calling an urgent meeting of the country's media groups after a hacking attack on the country's TV5Monde network by a group affiliated to Islamic State.
"The attackers took all 11 of the public broadcaster's TV channels off air from 10pm Wednesday to 1am Thursday (local time) and seized control of its social media accounts and website.
"The station's Facebook page carried messages reading "CyberCaliphate" and "Je SuIS IS", along with copies of ID cards and other documents purportedly belonging to relatives of French soldiers engaged in the battle against Islamic State."

It seems that many TV networks are very open to cyberattack - just as well that nobody would bother to attack New Zealand
