The hacker group Anonymous said that they will attempt to hack a number of Israeli websites on Tuesday, with cyber attacks possibly beginning on Monday.
In a video originally posted on March 4, a masked person said that the hackers will carry out an "electronic Holocaust" on April 7 as hackers from "around the world unite in solidarity with the Palestinian people."
The video showed images from last summer's Operation Protective Edge, including clips of Prime Minister Benjamin Netanyahu.
This is the fourth year in a row that Anonymous has threatened Israel with hacking, and attempts have been largely unsuccessful. The group also regularly threatens other governments around the world.
In 2014, the Shin Bet (Israel Security Agency) said it had opened a special cyber operations room in preparation for the hacking campaign, but found that the Internet onslaught produced only minor slowdowns on dozens of official sites. The group managed to take the Israel postal service and the Education Ministry websites down briefly and disrupt a handful of private websites. It also published a long list of phone numbers and email addresses belonging to Israeli officials.
Past attempts have also targeted the sites of Yad Vashem, the Prime Minister’s Office, and the Israel Defense Forces website, with limited success.
Individual pro-Israel hackers will also most likely be part of the defense. In 2013, Israeli hackers broke into the server hosting hackers sites that help coordinate the online attack on Israel. Under the heading “A few forgotten facts,” the hacker posted content such as “Israel became a nation in 1312 BCE, 2,000 years before the rise of Islam.” In 2014, Israeli hackers publically posted pictures of the Anonymous hackers by hacking into their computer's webcams.
