The second attack in a week has been launched on the Vatican City by Anonymous.
In a statement, translated from Italian, the attacker described the city as being "less secure than what you would like to believe, because, while the hype was directed toward the darkening of vatican.va, we took the liberty to implement a small incursion into your systems".
Last week the hacktivists took down the Vatican's official website in protest at "the execution of heretics and the burning of books during the Inquisition and more recently the sexual abuse of children by priests".
According to the Register, a Jesuit father confirmed to The Catholic News that the Vatican site and its news service L'Osservatore had been offline for several hours, with both of them temporarily redirecting to other sites carrying a message from Anonymous.
The Anonymous statement said: “The reasons that led us to dedicate ourselves to you are not just so frivolous [in] nature. Without going into the merits of the messages that your radio spreads (we have already expressed our thoughts on this matter at obscuration of vatican.va), we once again remind people like these messages are disseminated.
“Unfortunately it is now an established fact that you use repeaters with power transmission largely outside the bounds of the law, and is also sadly note the correlation between exposure to electromagnetic waves of high intensity and the onset of serious diseases such as leukemia cancer, cancer and many other terrible diseases.
“Many citizens who have the misfortune to reside in the vicinity of your repeaters have filed lawsuits, following the decline of their health. Anonymous can not tolerate these crimes continue, and we remind you that you are ‘guests' on Italian soil.”
It called for a review of the location of power and transmission equipment and warned that an attack will be extended again, "even [on] vatican.va just for the lulz".
