Hackers recently breached Saudi Arabian shopping sites in response to the publication of personal information on 400,000 Israeli citizens by a Saudi hacker.

"[Pro-Israel] hackers are threatening to release thousands of credit cards stolen from Saudi shopping sites," writes The Register's John Leyden.

"'If the leaks continue, we will cause severe damage to the privacy of Saudi citizens,' one of the hackers told Israeli news site Ynetnews.com," Leyden writes.
