The story claimed the famed rapper was alive and living in New Zealand.
A group with the Twitter name @LulzSec claimed responsibility and posted links to other hacks, including a video apparently taunting the network. Taunting messages were also posted on the group's Twitter page targeting the PBS program "Frontline."
The group was apparently unhappy with a program about "WikiSecrets," which recently aired on PBS.
The hackers also posted passwords for two internal PBS sites - one that media use to access the PBS press room and an internal communications website for stations.
PBS acknowledged it was hacked and pointed out the story on Shakur is fake.
