In new comments published on Sunday, a presumed Saudi hacker calling himself Ox-Omar threatened to 'finish Israel electronically' after attacking key Israeli websites and publishing details of thousands of its credit cards.

Ox-Omar said he would scale down his attacks on Israeli credit cards to reveal details of an average 200 a day after publicising nearly 400,000 of them over the past two weeks.

Last week, Abu Dhabi Securities Exchange (ADX) and the Saudi Stock Exchange (Tadawul) denied claims by Israeli hackers that their websites had been attacked.

Cyber-criminals claiming to be Israelis said they had brought down the sites of both the Tadawul and ADX in a retaliatory strike, days after an alleged Saudi hacker attacked the Tel Aviv bourse.

In his latest comments carried by the Abu Dhabi-based Alittihad daily and other regional newspapers, the mystery hacker also threatened he would disclose secret information which he said Israel had obtained through espionage.

“I am one of the strongest haters of Israel… I will finish Israel electronically… I can publish any information about Israel but I am just waiting for the right time and place,” the hacker said, according to the Arabic language press.

The papers quoted him as saying Israel’s war against the Palestinians in besieged Gaza Strip in 2008 and 2009 prompted him to launch his electronic assault on the Jewish nation.

“The end of Israel is very close… I will use all my powers and those of my supporters to achieve that,” he said.

“We had hacked some websites in the past but from now on, I, Ox-Omar, decided to hack only Israeli sites to harm it and make it suffer.”

Newspapers quoted him as saying he is not worried about being identified or arrested by any party.

“No one in the electronic world can find me, hence no one can arrest me,” he said, rebuffing Israeli claims that he could be an Iranian agent.

“I live in Riyadh and I am fighting for the children of Palestine… I want to tell these children to resist and that victory is very close.”
