Xbox and PlayStation networks say they are investigating after thousands reported having problems with the gaming networks.

A hacker group, "Lizard Squad," reportedly took the credit for the network crash, posting to Twitter Thursday, "Jingle bells jingle bells xbox got ran. oh my fun it is to troll of you morons ... hey!"

The hacker group claimed they crashed the networks by a tactic in which they showed denial of service attacks, overwhelming Sony and Microsoft's servers with traffic.

Xbox and PlayStation said Thursday they were working on the problem.

"We are aware that some users are reporting issues accessing PSN this morning," read a Tweet from the official PlayStation support account on Thursday. "Thanks for your patience as we investigate."
