One of my favorite Arabic news sources, Palestine Press Agency, has been hacked by someone named "Master Mind."
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!
