AnonGhost Team, an Anonymous subsidiery identified as supposedly being a Muslim hacktivist group, has been singled out by a Cyber Intelligence team for making a thread recently to launch cyberattacks against Israel. They went as far as to offer an exact date of the attack, April 5-7, 2014.
Shortly after the AnonGhost announcement, other groups, such as AnonGhost Tunisie and the Norwegian Ghost Cyber Attackers opened event-pages on anti-Israel Facebook.
It’s suspected that the primary targets by most of these groups are government websites. DDoSing has been the weapon of choice for most Anonymous groups, but concerns have been raised about potential database exploits leading to the leak of sensitive information.
