PlayStation network and Xbox Live risk to be taken down on Christmas by an anonymous group of hackers known as the Phantom Squad. The group claims not be linked with Lizard Squad, and declared to be a group of Gray Hat hackers that like the popular Anonymous have declared war on the Islamic State group. Last Christmas, both platforms faced the same issue, the group Lizard Squad hit both networks with a powerful DDoS attack, the services provided by Sony and Microsoft were paralyzed for several days. After the attacks, an 18-year-old was arrested in the UK, on January 16th along with a 22-year old Vincent Omari.”]
