An Israeli hacker published details of over 200 Saudi credit cards online in retaliation for a hack of Israeli credit cards the previous week by a hacker claiming to be from Saudi Arabia. The Israeli hacker, known as OxOmer, threatened to publish more Saudi card details if Arab hackers released any more Israeli data. OxOmer is reported to be an Israeli soldier. In further cyber attacks, Israeli hackers brought down the websites of the Saudi and Abu Dhabi stock exchanges in response to attacks on Israeli exchange and airline websites. An Israeli hacker known as Hannibal then claimed to have access to over 100,000 Facebook logins belonging to Arabs but said he would not post them as the Arab hackers had stopped.

2. Israeli hacker retaliates to credit card hacking
An Israeli hacker has published details of hundreds of Saudi credit cards online and is
threatening to post more in revenge for acts by Arab hackers.
Last week a hacker, claiming to be from Saudi Arabia, published information about tens of
thousands of Israeli credit cards online.It was one of the worst incidents of data theft in
Israel.Experts say the attacks draw attention to the potential for virtual or cyber wars in the
Middle East.According to the AFP news agency, at least two Saudi credit card holders have
confirmed that their personal details were compromised by the Israeli hacker, who identifies
himself as OxOmer or "Omer Cohen".They told AFP their banks had confirmed irregularities
with their credit cards.
In an online posting on Tuesday entitled "Free Saudi's credit cards!", the Israeli hacker listed
names, email addresses, phone numbers and numbers of over 200 cards, most of which were
within their expiry dates.
Speaking to the Jerusalem Post, OxOmer is reported to have said, "This is just the beginning".
He told the newspaper he had information on a further 300,000 working Saudi credit card
numbers. "If they publish one more little detail on Israel, we will attack in full force and
publish all of the credit card details," he said.Newspaper reports suggest OxOmer is an Israeli
soldier serving in Military Intelligence.
