Hackers breached the network 's internal systems , possibly aided by passwords openly broadcast by TV5 , overriding the broadcast programming of the company 's 12 channels for over three hours . Service was only partially restored in the early hours of the following morning and normal broadcasting services were disrupted late into April 9 . Various computerised internal administrative and support systems including e-mail were also still shut down or otherwise inaccessible due to the attack . The hackers also hijacked TV5Monde 's Facebook and Twitter pages to post the personal information of relatives of French soldiers participating in actions against ISIS , along with messages critical of President François Hollande , arguing that the January 2015 terrorist attacks were " gifts " for his " unforgivable mistake " of partaking in conflicts that " serve no purpose "
