The Army took down its homepage Monday after the site was hacked, the Army confirmed, with a group loyal to the Syrian government claiming responsibility.
"Today an element of the Army.mil service provider's content was compromised," Brig. Gen. Malcolm Frost, chief of Army public affairs, said in a statement Monday. "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 site remained down Monday afternoon.
Update: The Army.mil site was back online as of by about 7:30 p.m. on June 8.
Before the Army took it down, hackers reportedly posted a series of messages on the page, including "Stop training terrorists," and "Your government is corrupt don't listen to it." One of these messages mentioned the Syrian Electronic Army, which reportedly engineered the attack.
The SEA has claimed responsibility for past hacks targeting The Washington Post, Reuters and other media outlets, as well as online service providers and other types of websites. Screen grabs allegedly pulled from Army.mil before it was shut down appear on the group's Twitter feed, along with news reports of its accomplishments.
Other branches' websites appeared to be operating normally on Monday afternoon.
