US Central Command’s Twitter and YouTube accounts hacked

US Central Command has suspended its Twitter and YouTube accounts after they were hacked by ISIS claiming the “Cyber caliphate continues its cyberjihad.”  One message said: "American soldiers, we are coming, watch your back” and was signed by Isis. 

The hack happened as President Barack Obama was preparing a major speech on cybersecurity.His spokesman Josh Earnest said the US is looking into the Centcom hacking. He said they were investigating the extent of the incident, and that there was a significant difference between a large data breach and the hacking of a Twitter account.
