Other messages include threats to the American soldiers such as these messages: "AMERICAN SOLDIERS, WE ARE COMING, WATCH YOUR BACK. ISIS" and "In the name of Allah we are watching you."

The hackers also posted and published details about top U.S. officials including their emails, phone numbers and addresses. However, when the numbers were called, most of them were found to be outdated. There were also PowerPoint slides made public but it is not yet clear whether or not these plans are from the CENTCOM.

Another photo tweeted by the hackers showed what appears to be military plans and an image from a computer web that allegedly came from a military facility. The tweet warned that ISIS has already infiltrated the facility and the PCs of the military base.

As for the YouTube page, the CyberCaliphate is being held responsible for the hacking as they have posted propaganda videos in favor of the ISIS militants. Due to this, the accounts have already been suspended. and officials have ruled the attack as a form of "cybervandalism."

Officials said they are still investigating the hacking incident but noted that there was no valuable information released from the two social networking accounts.

According to Central Command spokesman Col. Patrick S. Ryder, as for their initial assessment, no classified information was released by the hackers and that the operational military networks were not compromised, based on their initial assessment.

This is not the first time that CyberCaliphate, attempted to hack websites. Last year, the group tried to hack a Maryland television station and a newspaper from New Mexico and they succeeded in hacking the Albuquerque Journal's website last December.
