Global hackers Anonymous have become the hacked, with the group's OpIsrael.com site taken over by an Israeli hacker.
The site had been used to coordinate attacks on Israel government and political party websites, but a hacker calling themselves "EhlrS" has posted pro-Israel information and videos, along with text reading "#opisrael are nothing!! Now is the time to know the truth about Israel".
ElhlrS reportedly hacked the website on Saturday, before hacking the site a second time on Tuesday.
The website remains affected at the time of writing.
According to the Jerusalem Post, hackers had earlier successfully brought down the website of the Prime Minister's Office, and that of the Likud party.
