It appears that the hacker is an Arab himself (the source code for the page indicates that the hacker is an MS-Word Arabic user.) Since PalPress is very anti-Hamas, it is possible that a Hamas hacker got to it. But there is no political message there, just a tag by the hacker.
A couple of weeks ago the Bank of Israel website was hacked by apparent Algerian hackers, but they seemed to be more skilled than this guy. No self-respecting hacker would put up a defaced page created with Word!
