The Syrian Electronic Army, the state-sponsored hacking collective operating under Bashar Al-Assad's regime in Syria, has just claimed a number of high profile scalps, hijacking the websites of the Independent, OK Magazine, the Telegraph, the Evening Standard and America's NHL.
Visitors to the sites are intermittently being presented with blank pages, and a pop-up message reading "you have been hacked by the Syrian Electronic Army." It is thought that it is using an exploit found in a third-party ad serving platform to carry out the hacks -- hence being able to strike numerous targets at once.
The Syrian Electronic Army uses its attacks to promote its cause, aiming to counteract what it claims is a "massive distortion of facts about the recent uprising in Syria". It's previously targeted other websites including the New York Times, the Sun, the Huffington Post and the Guardian.
Update: It appears our friends over at T3.com have been hit by the attack, too:
