First @YourAnonNews, one of the main Twitter accounts for the chaotic hacker collective, tweeted Golden Dawn New York's phone number to more than 630,500 followers:

Call the new New York offices of the Greek neo-Nazi party, Golden Dawn, and give them a warm welcome to the neighborhood: 347 670 3163

— Anonymous (@YourAnonNews) September 24, 2012

This was retweeted over 130 times. The account's followers apparently took the suggestion, as a short time later, @YourAnonNews made it clear that both the New York office's phones and website were down for the count:

GOLDEN DAWN NOT ONLY IS YOUR PHONE LINES TANGO DOWN, BUT UR WEBHOST R BELONG TO US:xanyc.org

— Anonymous (@YourAnonNews) September 24, 2012

Golden Dawn New York's xanyc.org was still offline at 8 p.m. ET.

@YourAnonNews's most recent tweet regarding the attack read, "This Machine Kills Fascists."
