As members of the Greek Hacking Scene Greek Hacking Scene informed us, the by clicking here of the Ministry of Labor, Social Security & Social Solidarity was violated 3 days ago.
According to the Greek Hacking Scene e-mail we received, the site was deformed, and it remained so around 3 hours until the administrators took it. 
The group mentions in their email that their purpose was not to harm but to send a message to all Greeks and the government.
So even though they had the opportunity, they did not mind archives and its data server hosting the page.
Those of you who want to read the GHS message, the defaced page is in the archive.org cache
