Amy Winehouse Hacked

The hacker group behind the e-vandalism -- who call themselves SwagSec -- took to Twitter this morning to gloat, posting a link to Amy's website ... showcasing their online dirty work.

SwagSec -- which took over Amy's website with a bizarre expletive-filled hacker-speak rant -- claims the goal is to "take back the Internet from the white devil" ... adding, "DEATH 2 THE WHITE DEVIL."
