'Watch your back, American soldiers, we are coming': ISIS hacks US Central Command.

The social media accounts of the US military's Central Command in Florida appear to have been hacked by ISIS sympathizers - posting threatening messages against troops, their families and the home addresses of 4-star US generals.

The cyber attack began at around 12.30pm on Monday when a message was posted to CentCom's Twitter account reading, 'In the name of Allah, the Most Gracious, the Most Merciful, the CyberCaliphate continues its CyberJihad.' 

The hackers also changed the photograph used on the the Twitter cover page to a masked jihadi with an underline that said 'i love you isis.'

The security breach, which occurred while President Obama was giving a speech on cyber security, saw death threats made against American soldiers and war game scenarios for conflicts with North Korean and Iran leaked online.

The CentCom YouTube account also had two propaganda videos for Islamic State uploaded.

One of the ominous posts slapped on the Twitter feed read 'American soldiers, we are coming, watch your back' while another warned, 'We won't stop! We know everything about you, your wives and children.'Most of the information leaked is readily available online according to the Washington Post, but the breach is still embarrassing for CentCom which is in overall command of the US-led coalition military campaign against ISIS in Iraq and Syria. 

The compromised Twitter account also published a list of generals and addresses associated with them, titled 'Army General Officer Public Roster (by rank) 2 January 2014.' 

In addition a pastebin link attached to the CentCom Twitter account contains a series of what appeared to be classified and sensitive Pentagon documents. 

Most of the leaked material was labeled 'FOUO,' which means 'For Official Use Only,' but none of it appeared to be classified or sensitive information, suggesting the hackers did not breach classified information.
