Just about a week after Saudi hackers published the credit card details of thousands of Israelis on the Internet, Israeli hackers announced they had the credit card information of thousands of Saudis.

The Israeli hacker story was reported by the Israeli site YNet, which said it confirmed the reports by checking some of those on the list the hackers say they have.

The Israeli hackers said they have "thousands of lists that include the personal details of citizens in the Arab state as well as the credit card details of those citizens."

"At the moment, we're holding on to the information and waiting for the right moment to publish it," they said.

"If the leaks continue, we will cause severe damage to the privacy of Saudi citizens," one of the Israeli hackers warned.

According to the report, one Saudi resident named Mohammed was contacted by telephone. He "confirmed the details and tried to find out how his telephone number and information was discovered," the website said.

The Saudi hack attack was called an "unprecedented criminal action that has nationalist aspects."

Initially they said they had the details of 400,000 Israelis and urged people to make purchases. In the end about 14,000 Israelis were affected.
