US Army website defaced by Syrian Electronic Army (http://arstechnica.com/security/2015/06/us-army-website-defaced-by-syrian-electronic-army/)
Site of US Cyber Command, Strategic Command also down.
Early today, the official website of the US Army (www.army.mil) was defaced by attackers claiming to be with the Syrian Electronic Army. In addition to a message on the page claiming attribution, the attackers also included a pop-up message to anyone visiting: "Your commanders admit they are training the people they have sent you to die fighting."
In truth, this is the equivalent of tagging/graffiti on a recruiting billboard along a seldom used highway.
