They have been noted by the US Attorney's Bulletin in reference to "Responsible hackers". They have won multiple categories in the "State of the Hack Awards"
The members of the groups were a mix of Grey hat and Black Hat hackers.
Members included; R4ncid, Bighawk, [P]hoenix, Immortal, RaFa, Squirrlman, odin, Phiz, and Jak-away(AKA Hackah Jak).
The group eventually fell apart and disbanded after the arrest of Hackah Jak in mid-2003. Although reports still indicate that many ex-members are active on the underground.
