In case you're not familiar, a distributed denial of service or DDoS attack involves overwhelming a server with tons of requests, making it unable to respond to legitimate users. It's a popular tactic used by digital pranksters to attack large companies.
The targets of this particular spree are mostly gamers. In addition to Sony, Riot Games and Blizzard also have suffered attacks.
But the DDoS attacks are particularly painful for Sony, who's still working to rebuild trust with its consumers after a massive 2011 attack on Sony's network compromised 77 million user accounts. The company recently agreed to a $15 million settlement over the breach.
The attackers have signaled that they're shifting focus to Microsoft's Xbox Live next — which is currently experiencing some issues with its social services.
