Hackers again showed how powerful electronic attacks can be when they forced Sony’s PlayStation Network and Blizzard’s Battle.net offline over the weekend. The same group responsible for shutting down the gaming platforms, which call itself the Lizard Squad, also claimed credit for sending a bomb threat via Twitter that grounded a plane carrying Sony Online Entertainment president John Smedley.
Blizzard said on Sunday that it had returned its network to service. Sony finally announced at 11:33 pm on Sunday through Twitter that the PlayStation network was also up again. After the first set of attacks, Lizard Squad indicated that it was targeting Microsoft’s Xbox Live network, and some users have experienced login difficulties.
