DALLAS -- Hackers infiltrated Sony's PlayStation Network and disrupted the travel plans of a top company executive by going on Twitter to suggest there was a bomb on his American Airlines plane.
Sony Corp. says the airline cut short the executive's flight Sunday and made an unplanned landing in Phoenix.
The plane with 179 passengers and a crew of six was scheduled to fly from Dallas to San Diego but stopped for what the FBI termed a security threat. American Airlines declined to comment on the threat.
A Twitter account called Lizard Squad tweeted to American Airlines there might be explosives on the plane carrying John Smedley, the president of Sony Online Entertainment, which makes video games.
Sony spokesman Satoshi Nakajima said Monday Smedley was on the plane.San Diego airport spokeswoman Rebecca Bloomfield said as the plane was being rerouted, the U.S. Transportation Security Administration told airport officials the FBI was investigating a tweet about possible explosives on the plane.
After landing in Phoenix, the plane taxied to a remote area of the airport, where passengers exited and their bags were searched by police officers with dogs. American Airlines spokesman Casey Norton said the plane later resumed its flight to San Diego.
Nakajima said the PlayStation Network's online services were unavailable from Sunday through Monday afternoon Tokyo time. While Lizard Squad tweeted that it was responsible for the hack that caused Sony's system outage, Nakajima said it remains unclear who compromised.
Sony said that no personal information was stolen as part of the breach. Hackers compromised the company's network -- including the personal data of 77 million user accounts -- in 2011. Since then, the network's security has been upgraded, the company said.
