An international group of hackers claimed Thursday to have published the details of 26,000 credit cards overnight, in the latest addition to a series of cyber attacks between pro-Palestinian and pro-Israeli hackers.

The group, "Team Poison", is one of the initiators of "OPfreepalestin", an organized attack on Israeli websites and citizens, and is considered to be one of the movement's most skilled groups.

In a statement made by the group, Team Poison wrote, "IsraHell has been committing genocide, infanticide, and every day homicide since 1948 and the world and her citizens have been aiding and abetting and financing this! We are all complicit in the murder of the innocent! It's time to make a stand! The tables have turned, We are no longer silent - Digital Intifada: #OpFreePalestine - The war has begun".

Team Poison was established in 2009 with the intention of acting in cyberspace against Israeli and American targets. Since then, it has cracked numerous websites, including those of Internet service providers, the United Nations, hi-tech companies and even the systems of countries who have ties with Israel.

Over the past month, pro-Palestinian and pro-Israeli hackers have been battling in cyberspace.

Two weeks ago, hackers shut down both the Tel Aviv Stock Exchange (TASE) and El Al’s respective websites. The attacks came one day after a hacker network threatened to carry out attacks on both sites and Hamas called for harsher hacking attempts against Israeli websites.

The network, which goes by the name “nightmare group,” was able to cause severe problems for both sites. By 10 A.M., TASE's website was only partially functioning, while El Al’s website did not function at all.

The following day, Israeli hackers brought down the websites of both the Saudi Stock Exchange (Tadawul) and the Abu Dhabi Securities Exchange (ADX), in a retaliatory attack. Then, the next day, Israeli hackers unveiled details of approximately 4,800 credit cards from various accounts held in Saudi Arabia.

The battle began on January 3, when the hackers, "Group-XP", claimed it had obtained personal information of about 400,000 Israelis, but checks carried out by the credit card issuers and the Bank of Israel determined that the details of between 14,000 and 15,000 active cards had been exposed. According to Maglan Internet Defense Technologies, a total of 31,000 credit card numbers had been exposed in all, some of them belonging to foreign nationals.
