The Israeli government announced on Sunday that more than 44 million hacking attempts have been made on the Israeli government websites since Wednesday, Reuters said.
These hacking were done by a group called Anonymous in their campaign "OpIsrael" and have occurred after the air assault on Gaza, the Examiner said.
In a statement by the group, they said that they launched the campaign after threats by the Israeli government to cut off all of Gaza's telecommunication links, BBC News said.
"We are ANONYMOUS and NO ONE shuts down the Internet on our watch," the Anonymous' statement said according the BBC News.
The group has warned the Israeli government not to cut off the telecommunication links and has threatened the government that if the military attacks in Gaza continue, the group will unleash their "full and unbridled wrath," BBC News said.
While most of the attacks have come from Israel and the Palestinian territories, there have been attacks from around the world, Reuters said.
"The ministry's computer division will continue to block the millions of cyber attacks," Finance Minister Yuval Steinitz said to Reuters.
Both sides in the Gaza conflict are using social media as a method of warfare, Reuters said.
"The war is taking place on three fronts. The first is physical, the second is on the world of social networks and the third is cyber," Israel's chief information officer Carmela Avner said to Reuters.
