Anonymous claims the following:
The Israeli Intelligence Agency has been attacked & hacked by hacktivist groups Sector404 & Anonymous.
Sector404 initiated a distributed denial of service attack on the mossad website (www.mossad.gov.il) whilst Anonymous hacked the site & leaked sensitive data from the database related to 30,000 mossad agents.
The leaked data includes addresses, phone numbers & general contact information regarding Mossad Agents.
The attack was done under the banner #OpIsrael which is an operation involving various groups and individuals that will take place on the 7th April 2013 with the main objective being to remove Israel from cyber space. As its not the 7th of April yet I guess this attack is just the beginning.
