Summary Box: Hackers busted, 1 is FBI informant

THE CASE: Charges were filed against five people, including a Chicago man, suspected of hacking into corporations and government agencies around the world. Authorities say their crimes affected more than 1 million people.

THE INFORMANT: Authorities say a legendary hacker known as “Sabu” was captured last June and had been working with the FBI for months to help build a case against the five others.

THE RING: Authorities say the six were all associated with the loosely organized worldwide hacking group Anonymous, and some were also part of the elite spinoff organization called LulzSec.
