A group referring to themselves as the Gaza Hacker Team launched a cyber attack on the Israel Fire and Rescue Services' website early Friday morning, in the latest of a string of cyber-terror attacks against Israeli interests.

The same group hacked into Deputy Foreign Minister Danny Ayalon's website last week. In Friday's attack the group placed a crossed out picture of Ayalon with footprints superimposed over his face on the Fire and Rescue Services' site.

The hackers threatened to commandeer more Israeli websites and wrote "death to Israel" in Hebrew.

Following the attack on Ayalon's personal site last week, the deputy foreign minister said that breaches of Israel’s cyberspace are a breach of sovereignty similar to terrorism and should be treated as such.

He also referred to the recent cyber theft of thousands of Israeli credit card numbers, saying it was a warning sign, but that Israel – as one of most advanced countries in the world in terms of cyber security – knew how to protect itself.

Israel needed to take an example from the US, which recently declared that it reserved the right to respond to cyberspace attacks – seen as acts of war – with conventional weapons, Ayalon said.
