TV5 targeted in ISIS-inspired cyber-attack which forced the network off air
French television network TV5Monde said it had been hacked by individuals claiming to belong to the Islamic State group, who brought television broadcasts to a halt and and hijacked its websites and social networks.
The Paris-based company was able to partially resume television broadcasts by 1:00 am (2300 GMT) after a three-hour blackout, the network's director-general Yves Bigot told AFP, but added its systems had been "severely damaged" by an "unprecedented attack".
The hackers briefly cut transmission of 11 channels belonging to TV5 Monde and took over its websites and social media accounts.
They posted documents on TV5Monde's Facebook page purporting to be the identity cards and CVs of relatives of French soldiers involved in anti-IS operations, along with threats against the troops.
"Soldiers of France, stay away from the Islamic State! You have the chance to save your families, take advantage of it," read one message on TV5Monde's Facebook page.
"The CyberCaliphate continues its cyberjihad against the enemies of Islamic State," the message added.
TV5Monde had regained control of its social networks by 2:00 am Thursday, the director-general said, but television broadcasts were likely to take hours, if not days, to return to normal. The attack would have required weeks of preparation, he added.
Bigot told AFP earlier in the evening: "We are no longer able to broadcast any of our channels. Our websites and social media sites are no longer under our control and are all displaying claims of responsibility by Islamic State."
Its websites were still offline by 4:00 am, displaying an "under maintenance" message to visitors.
The hackers had accused French President Francois Hollande of having committed "an unforgivable mistake" by getting involved in "a war that serves no purpose".
"That's why the French received the gifts of Charlie Hebdo and Hyper Cacher in January," it said on the broadcaster's Facebook page, referring to the twin attacks by Islamist gunmen in Paris that left 17 people dead over three days and deeply shocked France.
France is part of a US-led military coalition carrying out air strikes against IS in Iraq and Syria, where the jihadist group has seized swathes of territory and declared an Islamic "caliphate".
More than 1,500 French nationals have left France to join the militants' ranks in Iraq and Syria, where they represent almost half the number of European fighters present, according to a report released Wednesday by the French Senate.
TV5Monde is broadcast in more than 200 countries worldwide.
