The official websiteσελίδα of Golden Dawn has been out of business since noon as it was attacked by hackers, as stated by the "party" in an announcement, which of course we will not publish.
If you try to visit the website it just will not open.
The official url of the page seems to redirect to http://www.xryshaygh.com/?COLLCC=969863603& so access is impossible.
At the moment, there has been no official announcement from hackers who claim responsibility for the attack. The Anonymous, however they had declared recently that they will "hit" the far-right Greek "party."
