The Saudi hacker on Wednesday leaked the details of a further 200 Israeli credit cards, in response to the Israeli hacker who published the details of over 200 Saudi Arabian credit cards on Tuesday.

An Israeli hacker identifying himself as "OxOmer" said he was retaliating for a hack on Israeli databases that released the credit card information of thousands of Israelis last week, revealing what he said were hundreds of Saudi credit card numbers.

In addition to his response to the Israeli hacker, the Saudi hacker, who identifies himself as 0xOmar, also responded to claims by an Israeli blogger last week, that he had found out where 0xOmar was based.

“I saw a few idiots saying that they found me, in Mexico, one in Riyadh, one in Dubai,” he said, adding that no one would be able to track him down.

0xOmar went on to say that he had gained control of many computers around the world via email, and that those who claim to have found his true location, have in fact located one of these computers.

“Excellent, you found one of my poor victims,” he said.

A week ago, Saudi hacking group Group-XP claimed it had obtained personal information of about 400,000 Israelis, and files containing the information were posted online by 0xOmar.
