Sony Corp said on Monday its PlayStation Network was back online after it suffered a cyberattack and was unavailable over the weekend.
The network was taken offline “due to a distributed denial of service attack ... an attempt to overwhelm our network with artificially high traffic,” Sony said.
“We have seen no evidence of any intrusion to the network and no evidence of any unauthorised access to users’ personal information.”
A hacker group going by the name Lizard Squad claimed responsibility.
“Sony, yet another large company, but they aren’t spending the waves of cash they obtain on their customers’ PSN service. End the greed,” one of its Twitter posts said.
The cyberattack coincided with a bomb scare on an American Airlines plane with a senior Sony executive on board, according to a report in US media.
The Federal Bureau of Investigation launched an investigation, the report said.
