We believe this was an attack that had been planned for some time
The daring attack saw propaganda material posted on the websites, and there were blank screens for hours on the TV channels.

Yves Bigot, the Director General of TV5, said: “We noticed that unidentified people had already made several attempts to break into our system but they didn’t do anything.
“So this leads us to believe that yes this was an attack that had been planned for some time.”
TV5 says it is working with national security officers to try to track down who is responsible and how firewalls at the channel were able to be breached.
The world service of TV5 is broadcast in more than 200 countries.
