On January 12, 2014, the pro-ISIS hacker group CyberCaliphate hacked the Twitter and YouTube accounts of the U.S. Armed Forces Central Command (CENTCOM). The group used the accounts to disseminate their propaganda, as well as to leak information on CENTCOM personnel and other documents. The Pentagon later said the information posted by CyberCaliphate was not "highly classified."
The CENTCOM Twitter account was subsequently taken offline, and the official CyberCaliphate Twitter account, which also announced the hacking, has been suspended.
CyberCaliphate began operating only recently, and has already claimed responsibility for multiple cyber-attacks on U.S. targets, including, on December 24, 2014, the Albuquerque Journal and unnamed "official network communications." The group also claimed to have hacked the FBI's New Mexico office on January 7, 2015.
Following are several tweets made by CyberCaliphate from the hacked account (some info has been blurred out by MEMRI), as well as from CENTCOM's YouTube page, and from CyberCaliphate's own Twitter account, as well as expressions of support for the hack from the Jihadi Media Platform (a pro-ISIS message board):
