LulzSec

As of yesterday, the FBI arrested 5 key leaders of the hacktivist group called LulzSec. "LulzSec is only a small piece of the greater hacktivist threat, and in itself is an offshoot of the larger group known as Anonymous." I believe this is good because the article goes into further detail about how well coordinated the tasking was for this sting and that they caught one member and used him to catch the other suspected members.
