Sony's PlayStation Network Restored After Cyber Attack

Sony Corp's PlayStation Network was back online following a cyber attack that took it down over the weekend, which coincided with a bomb scare on a commercial flight carrying a top Sony executive in the United States. Sony said on its PlayStation blog that its PlayStation network had been taken down by a denial of service-style attack, which overwhelmed the system with traffic, but did not intrude onto the network or access any of its 53 million users' information.
