Hackers broke into the NBC News Twitter account and sent a series of tweets falsely telling the news outlet’s 129,000 followers there was a new terror attack on ground zero. “Flight 4782 is not responding, suspected hijacking. One plane just hit ground zero site at 5:47. #groundzeroattacked,” the hackers tweeted. A group calling themselves the Script Kiddies claimed responsibility for the hack, publicizing its own Twitter account — which was immediately shut down.
