Update 3: According to SITE (the Jihadist Threat Monitopring Service), the recent cyber-attack on The United States Central Command's (CENTCOM) Twitter and YouTube accounts, attributed to pro-Islamic State (IS) hacking group "CyberCaliphate," has been celebrated as a massive achievement among IS fighters and supporters on Twitter.

Update 2: Centcom's YouTube account has also been hacked...

Update: 40 minutes after the first hacked tweet appeared at 12:29pm Eastern, the Centcom account has been suspended.

Another day, another escalation in the conflict between supporters of the Islamic State and western powers, in this case the Twitter account of the US Central Command (@Centcom), which appears to have been hacked, and where compromising tweets revealing details about military members and potential conflict scenarios involving China and North Korea, are being sent out in real time.

This is the threat that was released via the hacked account moments ago:

A sampling of the hacked tweets:

Perhaps of increased concern: the disclosure of Centcom's "China scenarios"
