A group of Israeli hackers claims to have attacked the Web sites of stock exchanges in Saudi Arabia and Abu Dhabi in retaliation for a cyber attack on Israel's Tel Aviv Stock Exchange.

"The Israeli group, calling itself IDF Team, said it was also responding to cyber attacks on the websites of the national airline El Al and several Israeli bank websites," writes Computer Weekly's Warwick Ashford.

"The cyber attacks and counter attacks look set to escalate, with the IDF Team warning that if attacks from Saudi Arabia continue, they will 'move to the next level which will disable these sites longer term [and] may come to weeks or even months,'" the article states.
