On August 27, 2016, the Twitter account of Ghost Squad Hackers (GSH) claimed credit for hacking the websites of the Bank of Israel and the Israeli Prime Minister’s Office. The group used a denial-of-service (DoS) vulnerability in the underlying web servers to take down the websites. S1ege, GSH’s leader, told Softpedia that the Bank of Israel website was back online after six hours, after the bank’s IT staff moved the site to new servers.

Asked for the reason behind the hack, S1ege, GSH’s leader, told Softpedia the following:
“We are attacking Israel for the ongoing atrocities they are committing on the Palestinian people. They just recently bombed Gaza again. The genocide needs to end. They are expanding an empire into land/ground that they do not own, over a book. There is a perpetual silence in the mainstream media. We hope our attacks will bring more awareness to this subject and bring more protests to this issue.”
S1ege also spoke of plans for future attacks to come in the following days:
“Yes we have some attacks planned for Israel. We, in [the] past, leaked IDF [Israel Defense Force]’s database. We plan to do similar attacks in the future if there is no word of the ongoing genocide in Israel. The United States mainstream media works as stenographers for the U.S. government and speaks nothing of this its corruption at it’s [sic] finest. We will not stand idly by and let it continue. We also plan to attack the Syrian government.”
Background On Ghost Squad Hackers
In early June, GSH announced #OpSilence, which they characterized as months-long DDoS attacks against mainstream media outlets due to their perceived failure to report on conflict in Palestine and war crimes happening in Syria. Outlets targeted in #OpSilence included FOX News and CNN. GSH also claimed to be behind #OpIcarus, a month-long DDoS campaign against banks and other financial institutions around the world.
On July 31, 2016, GSH hacked the Twitter account of Afghan Chief Executive Abdullah Abdullah.
On August 23, 2016, GSH also claimed on its Twitter account to have hacked the Israeli Ministry of Foreign Affairs.

GSH was also responsible for revealing personal details of members of the United Cyber Caliphate (UCC), including its leader, Mauritania Attacker. In the wake of this “dox,” S1ege told AnonHQ.com of the group’s affiliation: “Although we are Muslims Christians and Atheist we have no one religion and we accept all. But (it’s true that) majority of us are Muslims and we believe in true Islam not this fake ISIS shit.”
