The hacker collective Anonymous has released a video threatening Israel with a massive cyber-attack, which it termed an 'Electronic Holocaust', on April 7. The attack will be part of the ongoing #OpIsrael, in which pro-Palestinian hackers target Israeli websites. According to a speaker in the video, "as we did many times, we will take down your servers, government websites, Israeli military websites, and Israeli institutions... We will erase you from cyberspace in our Electronic Holocaust."
