A new hacking group is threatening to carry out similar attacks by taking down the Xbox LIVE and PlayStation Network for a week during Christmas. The attacks could prevent millions of gamers worldwide from enjoying their newly opened Christmas gifts and accessing games online. The group has turned its crosshairs toward the gaming networks. If the DDoS attack on PSN and XBox Live is carried out successfully, it will again ruin the Christmas holidays for millions of video game lovers worldwide. Microsoft, at least, acknowledged issues with Xbox LIVE when Phantom Squad claimed responsibility for knocking Reddit offline.
