Lizard Squad, the anonymous hacker group who claimed responsibility behind the recent cyber attack on Sony's PlayStation Network, continues to threaten the gaming community, ABC News reported.

Aside from Sony, the group has also taken credit for attacking sites such as Battle.net and League of Legends. Lizard Squad then expanded its reach by boasting on Twitter that it had taken down the Vatican's official website.

Despite the group's claims on Twitter, authorities have not yet discovered a link between the Lizard Squad and the hacked sites.

Aside from its cyber misdeeds, the group also caused a serious security issue by hinting that the plane Sony Online Entertainment's president John Smedley was riding had an explosive device on it, according to Tech Times.

"@AmericanAir We have been receiving reports that @j_smedley's plane #362 from DFW to SAN has explosives on-board, please look into this," Lizard Squad tweeted.

Following the squad's tweet, Smedley's plane was diverted to Phoenix where it was searched for explosives.

"Yes. My plane was diverted," the executive tweeted. "Not going to discuss more than that. Justice will find these guys."

According to Cole Stryker, author of the book "Hacking the Future: Privacy, Identity, and Anonymity on the Web," the Lizard Squad could either be composed of several people or just one person.

Either way, Stryker believes Lizard Squad is just trying to have fun.

"Very trollish, prankestry," the author said. "I don't believe this person genuinely wants to be involved in geopolitics. I think this person is just having a lauch."

For the attack on the PlayStation Network, Lizard used a distributed denial of service (DDoS) attack that disabled users from accessing the side.

Stryker said there are two ways of accomplishing this.

"It can be a bunch of people getting on their computers and bombarding a website with dummy traffic in order to overload the servers or it could be a single actor who has access to a botnet," he said.

"[This] is a network of compromised computers that have been taken over for the person conducting the attack," he added. "If it is one person, it is someone who has a wide network of computers under his control and the owners might not realize their machines are being compromised."

Sony noted that it has already contacted the FBI for the capture of Lizard Squad, Game Zone reported.

Stryker is confident that the given the authorities' resources, Lizard Squad will eventually get caught.

"It's not a matter of if, it's a matter of when," he said.
