(JTA) – The international hacking group Anonymous said it will target Israeli websites in a coordinated effort it called an “electronic Holocaust.” The organization said that its “elite cyber squadrons” would attack Israeli servers, government and military websites, banks and public institutions on April 7.

Exactly one year ago, Anonymous launched an identical attack against Israel that brought down the websites of the country’s postal service and Education Ministry, as well as some private Israeli websites. The group also published online a list of phone numbers, emails and passwords of senior Israeli officials. The year before, the group took down dozens of websites and published online a list of hundreds of Israeli email addresses and credit card numbers.
