Hacker “OxOmar,” dubbed the “Saudi Hacker,” struck again on Monday, this time shutting down the El Al and Tel Aviv Stock Exchange information site. The cyber attack did not affect the site on which investors trade stocks, and trading was not affected.

The hacker struck last month by invading thousands of accounts of Israeli credit card holders.

The El Al site was shut down as of mid-morning, and the Stock Exchange site was available but not operable.

OxOmar blocked the El Al site but did not take control of it or damage its content. The real damage is to the image of El Al, which like every other airline invests huge sums of money in its websites so travelers can order tickets on line and check schedules.

A pro-Israeli computer hacker retaliated to the first hacker attack on credit cards, invading Arab credit card accounts and publishing details of accounts of 20,000 Arab Facebook clients.

The hacker, who calls himself Hannibal, said he gained information that can be used to break into the bank accounts of 10 million Muslims in Saudi Arabia and Iran.

Intelligence and computer experts have predicted for several years that the next war may take place in “cyberspace,” and Hamas this week urged its supports to increase their efforts to break into Israeli sites.

"Penetrating Israeli websites means opening a new field of resistance and the beginning of an electronic war against Israeli occupation, Hamas spokesman Sami Abu Zuhri told Bloomberg.
