TOKYO — Sony, maker of the world’s best-selling video-game console, resumed services at its online game and entertainment networks after a hacking attack knocked them off line.
PlayStation Network and Sony Entertainment Network, which enable gamers to play each other and access content, had been taken off-line by a so-called distributed denial of service attack, the Tokyo-based company said in a blog posting. The company has seen no evidence that personal information was accessed by computer hackers who drove artificially high traffic to Sony servers, it said.
A Twitter account with the name Lizard Squad posted messages claiming responsibility for the PlayStation Network outage and also comments about explosives on a flight carrying John Smedley, president of Sony’s online entertainment unit. The threat of explosive material on the plane was referred to the FBI, the company said earlier Monday.
American Airlines Flight 362 from Dallas to San Diego was diverted to Phoenix for a security-related issue, Michelle Mohr, a spokeswoman for the carrier, said by phone.
