Isis cohorts hijack US army websites
Hackers claiming to be working on behalf of Islamic State militants briefly seized control of the Twitter and YouTube sites of the military's US Central Command last night.
Among messages seen by anyone following the account was: "American soldiers, we are coming, watch your back. Isis."
As well as posting direct messages and threats, the group used the incursion to post images of documents containing what appeared to be sensitive Pentagon information.
They also posted links to other sites where more information was available for download.
However, it was not clear if those documents had been stolen as a result of an earlier, successful hack into Pentagon servers or if they were in fact already publicly available. A US Defence Department said nothing in the trove of information being made available was classified.
A Pentagon official said that while the breach was certainly an embarrassment to the US government, it was "not a security threat".
One of the documents appeared to be slides depicting apparent "scenarios" for conflict with North Korea and China.
The hackers titled the Twitter page CyberCaliphate with an underline that said "i love you isis."
They added: "We broke into your networks and personal devices and know everything about you. You'll see no mercy infidels. ISIS is already here, we are in your PCs, in each military base."
