The hacker collective famously known as Lizard Squad recently attacked the North American servers of the "Destiny" and "Call of Duty: Ghosts" games, Tech Times reported.
The group used a distributed denial-of-service (DDoS) attack on the servers which left users unable to access their accounts. The DDoS works by flooding the system with an overwhelming amount of requests until the servers crash.
Gamers who attempted to access their accounts were greeted by the message, "Lost Connection to partner service. Please check your network configuration and try again."
Due to the attack, "Destiny" developer Bungie released an announcement to gamers to address the issue.
"We're aware of connection issues affecting portions of the 'Destiny' player base and we're working to correct the problem. Please stay tuned," the studio tweeted.
Aside from "Destiny" and "Call of Duty," a number of servers for EA games such as "FIFA," "Madden," and "Sims 4" also experienced the same problem.
Although Lizard Squad has not yet released an official statement confirming its involvement in the attack, the group made a series of tweets regarding the incident, according to Game Spot.
"We're predicting a lot of mad gamers this weekend," the group posted days before the attack.
"Woah, I think there are some Ghosts haunting Destiny," Lizard Squad tweeted after news of the problem with the servers broke out.
The attack comes a month after the group launched a similar assault on Sony's PlayStation Network and Microsoft's Xbox Live.
The group then threatened Sony Entertainment Online's president John Smedley by posting that the plane he was traveling in had a bomb in it, according to Forbes.
The security threat forced the plane to redirect its route and land in Phoenix.
Since then, the group has gained the attention of authorities including the Federal Bureau of Investigations. However, Lizard Squad still continues to go about its hacking activities despite the ongoing investigations of law enforcers.
