The hacker group known as Anonymous launched a significant cyberattack against a large number of Israeli Web sites this weekend.

Anonymous and its allies claim the attacks have been widespread and very successful, causing more than $3 billion in damage.

Israeli officials said there have been no major disruptions:

“So far it is as was expected, there is hardly any real damage,” Ben Yisrael told the media. “Anonymous doesn’t have the skills to damage the country’s vital infrastructure. And if that was its intention, then it wouldn’t have announced the attack ahead of time. It wants to create noise in the media about issues that are close to its heart.”

It is an assertion that the Anonymous hackers dispute.

At the moment, the Knesset website and Prime Minister’s Office website both appear to be down.
