So, after announcing an alleged hack to Italian Prison Guards, the threatening tweets anticipating the latest hack, have suddenly disappeared from @LulzSecITALY and replaced by a tweet announcing a day of relax. Of course the doubt if the announcement was a hoax or not remains… But in my opinion this is not the most relevant point of the story.
Update August 7: Italian Prison Guards, or better to say SAPPE (Sindacato Autonomo Polizia Penitenziaria which stands for Independent Union of Prison Guards) were effectively hacked.
The attack was disclosed 24 hours later with a resounding defacement on the Union Web Site www.sappe.it (currently unavailable). Not only the Homepage has been defaced, but also a message was left on pastebin (translation here).
