Bank Hapoalim is one of the latest Israeli institutions to come under cyberattack, The Next Web reports, citing Israeli tech blog, NewsGeek.

With attacks continuing to take place by both Israeli and Saudi hackers, Iranian hackers are now believed to have been involved in the latest attack.

Since January 3, Saudi and Israeli hackers have continued to exchange blows, attacking governmental and official websites, targeting Facebook users, and revealing credit card information.

While no one has taken credit for the most recent attack on Israel’s largest bank, fingers have been pointed at Iranian hackers. According to NewsGeek’s Editor in Chief, Yaniv Feldman, the attack is most likely in retaliation for the Stuxnet attack, which may have infected up to 16,000 computers in Iran.
