Hacktivist group, Phantom Squad, has taken the credit for taking down Sony’s PlayStation network on 4 January. There has been no comment from Sony and the network has been fully restored. The group announced in December 2015 that it was planning to take down Lizard Squad and the PlayStation network in a distributed denial of service (DDoS) attack. Both networks have previously been attacked, with hacktivist group Xbox Live taking them down on 25 December 2014. In a tweet, Phantom Squad revealed that it had targeted Sony to highlight that the makers of these devices are not doing enough to adequately safeguard their networks.
