Iran and its terrorist allies, Hezbollah and Hamas, are carrying “non-stop” cyber attacks against Israel’s central computer systems, Prime Minister Benjamin Netanyahu revealed Sunday in his address to an international conference on cyber warfare at Tel Aviv University.

Without elaborating, Netanyahu said that “vital national systems” had been targeted. Suspected targets include water systems, power stations, and banking sites. “In the past few months, we have identified a significant increase in the scope of cyber attacks on Israel by Iran. These attacks are carried out directly by Iran and through its proxies, Hamas and Hezbollah,” he added.

The prime minister said also that Israel is defending itself from such attacks by aspiring “to set up a digital Iron Dome” referring to the Israeli made anti-rocket system, which proved itself against Hamas’ rockets and missiles fired from Gaza last year.

Netanyahu concluded by saying that “despite the non-stop attacks on us, you hear only about a few of them because we thwart most of them,”

Ten years ago, the Shin Bet, Israel’s domestic general security service, founded a special unit to defend computers at strategic installations from hostile cyber penetration. But in view of the increasing cyber-threats, Netanyahu created a national cyber authority in 2011.

Two months ago Israel said it thwarted a pro-Palestinian cyber attack campaign against government websites. Israeli officials said those attacks briefly disrupted several sites and that security protocols were upgraded in response.
