Hackers Claim Responsibility For PlayStation Network And Xbox Live Outages On Christmas

Avid gamers were not happy this Christmas.

After suffering a cyberattack at the hands of North Korea, Sony has been hit by yet another wave of hackers.

On Christmas, Sony's PlayStation networks, as well as Xbox Live's gaming networks, experienced massive outages preventing users from signing in. The cause? Lizard Squad, an infamous hacking group that has targeted "Call of Duty," "Destiny" and other games in the past — and now, they're taking responsibility for the PlayStation and Xbox outages.

Sony and Xbox both acknowledged the outages on Twitter, and as of Friday (December 26), were still working on restoring service for gamers.

Earlier in the month, Lizard Squad threatened to disrupt Xbox Live and PlayStation Network service on Christmas day. Sony and Microsoft have stopped short of identifying Lizard Squad as the culprits responsibility for the outages, but the timing, and Lizard Squad's claims of responsibility, certainly raise some eyebrows.
