Facebook removed a page belonging to the Moroccan Ghosts, an anonymous hacker group that took credit for defacing the webpages of four Jewish institutions in the U.S., according to the Anti-Defamation League, which alerted the social media platform.
The Facebook page boasted of their cyber-attack: “Hacking 4 formal Zionist temples in America or in more accurate words  dirty places to conspire and plot against Palestine.”
The hacked websites were of the Union for Reform Judaism’s institutions in Colorado, New Jersey, Massachusetts and Georgia, the ADL said on Tuesday.
They replacing the website homepages with an image of a man wrapped in a Palestinian flag, alongside the tagline, “When injustice becomes law … Resistance becomes a duty.”
In 2012, Moroccan Ghosts defaced Jewish congregational websites with their logo and an hour-long video denying the Holocaust, the ADL said.
ADL said: “This latest cyber-attack is part of a larger trend of politically motivated hackings targeting the websites of perceived supporters of Israel. ADL offers guidance to Jewish institutions regarding online and digital security.”
