One hacker, who claimed to be a member of the Saudi hacking group, Group-XP, said he revealed information including credit card details, personal addresses, names, phone numbers and ID numbers of individuals listed on the website, One.co.il.

Israeli credit card companies said Monday that the list is repetitive and only includes 14,000 Israelis.

They said they have blocked all the cards on the list, and will return customers their money should any purchases be made on the cards.

People who visited Ones website on Monday were redirected to a page on pastebay.com, where a message by a hacker who identified himself as xOmar 0 suggested visitors download a linked file containing a database of Israelis and their personal information.

The file included a number of lists with the details of tens of thousands of people. One of the lists included what the hackers termed 65 Zionists, who purchased products from a website called Judaism. Another list included the details of 500 people who donated to rabbis.

According to the message posted by the Saudi hacker, Group-XP hacked into multiple Israeli websites from which Israelis frequently purchase products with credit cards. He said the groups goal was to reach the credit card numbers of one million Israelis.

We decided to give the world a gift for New Year's – the personal information of 400 thousand Israelis, he wrote.

He wrote that they found the idea of 400 thousand people crowding Israeli credit card companies and banks and complaining their credit card details were stolen, watching as Israeli banks shredding 400 thousand credit cards and issuing new ones, was appealing.

The website, One, said they were looking into the issue, and shortly after the page was hacked it returned to normal activity.
