Is any authority safe from the hacker group Anonymous? Just over a week ago, they waged cyberwar on Albuquerque after the city's police department shot a homeless man for illegally camping. Now, a year on from their last cyberattack on the Israeli government, they've hit them again. 

Yesterday, the group took down a number of Israeli websites, namely the Defence Ministry and the Prime Minister's office. Anonymous also published credit card details and email addresses from the database of a company said to be selling weapons to the Israeli army.

On Sunday, the pro–Palestinian #OpIsrael campaign also uploaded a video of warning to YouTube, calling for Anon "brothers and sisters to hack, deface, hijack, database leak, admin takeover and DNS terminate the Israeli cyberspace by any means necessary".

"You can NOT hide the barrage of bullets you use to kill and maim Palestinians," the video continues. "The further assault on the people of Gaza, who have been flooded by your sewage, terrorized by your military apparatus, and left to die at the border while waiting for medical attention will NOT be tolerated anymore. Your vicious campaigns to attack Palestinian solidarity groups worldwide through censorship and legal wrangling has also NOT gone unnoticed."

Israel's authorities said that no major damage had been done as a result of #OpIsrael.
