attacked Sony and Nintendo in the past, has tweeted that it's committed three distributed denial of service attacks against gaming companies today, bringing down EVE Online's Tranquility server, Minecraft's multiplayer services, and the Escapist Magazine's website. EVE Online's CCP has confirmed both the outage and the attack, the Escapist is unreachable at the moment, and Minecraft creator Notch says that things were down, but supposedly service has been restored.
LulzSec hasn't shared a reason for the attacks just yet, but we can only guess it's, as they say, "for teh lulz."
Update: The group has gone after Riot Games' League of Legends servers as well. Attempting to log in to the game gives a "server busy" message, though there's no official word from the company yet.
Update: Statement from CCP after the break. EVE Online still seems to be down.
