PBS was just hacked by a group of Internet vigilantes who put up a bogus story of Tupac Shakur and Biggie Smalls being alive and well in New Zealand. The hackers claimed it was revenge for what they thought was an unfair portrayal of Wikileaks in a PBS documentary.

If you think Anonymous did it, you’d be wrong. Instead, a new group called LulzSec (Lulz Security) did it.

LulzSec isn’t really new – it was just thrust into the spotlight for the first time while Anonymous previously perpetrated all the high-profile stunts.

An earlier attack by LulzSec targeted Fox.com. They hacked the website, posted the passwords of Fox employees, altered several LinkedIn accounts of these employees, and hijacked the Fox15 twitter account. It also previously targeted Sony's music website in Japan.

LulzSec claims to be a separate entity from Anonymous. In an interview with Forbes, LulzSec member Whirlpool said the group hacks for “lulz and justice.”

After its PBS exploit, LulzSec claims to be planning bigger things. On its Twitter account, it stated it was hacking Sony right now.

“Hey @Sony, you know we're making off with a bunch of your internal stuff right now and you haven't even noticed? Slow and steady, guys,” boasted one Tweet early in the morning on Tuesday.

“#Sownage (Sony + Ownage) Phase 1 will begin within the next day. We may have a pre-game show for you folks though. Stay tuned,” warned a Tweet from May 29.

“We're working on another Sony operation. We've condensed all our excited tweets into this one: this is the beginning of the end for Sony,” stated another Tweet from May 27.

A Sony spokesperson did not immediately respond to IBTimes' request for comments.

AT&T may be another target of LulzSec.

One Tweet from May 17 read “AT&T aren't going to enjoy what The Lulz Boat is cooking.” Another read “We've got some curious items from the AT&T ship, and our FBI-related plunder is still on course. Smooth sailing! “
