The Syrian Electronic Army (SEA) has claimed responsibility for an attack on the main website of the US Army that led to the site being taken offline.
The www.army.mil site was defaced with pro-Syria messages late on Monday, according to reports. A statement released to NBC News from the Army confirms the attack.
"Today an element of the Army.mil service provider's content was compromised," said US Army chief of public affairs brigadier general Malcolm Frost.
"After this came to our attention, the Army took appropriate preventive measures to ensure there was no breach of Army data by taking down the website temporarily."
The SEA admitted its role through social media accounts, posting images of defaced pages on Twitter.
The hacking group takes issue with the suggestion that no data was taken, and claims that it may release information at a later date.
"On Monday evening at 8:05PM, the SEA hacked the official website of the US Army. The hack was [performed] after targeting the CDN service used by [the] US Army website," it said.
"The SEA was able to intercept the content paths after discovering an exploit in the [Control] Panel that provides the ability to edit the protected content paths.
"The SEA qualify the data obtained from this attack and other old attacks to be published later if that was necessary."
This is the second time that official US properties have come under attack this month. A major hack on the US Office of Personnel Management might have exposed the details of government workers from the past four decades.
The suggested attacker is China, but the Chinese government has denied any involvement. The US government has admitted that it is facing a dedicated opponent, but did not name any suspects.
