A pro-Islamic State (IS) hacking group calling itself the "CyberCaliphate" claimed hacking the Twitter and YouTube accounts of the U.S. Central Command (CENTCOM), posting on them IS videos and alleged documents it stolen from networks and personal devices.
The group posted an English statement on Pastebin on January 12, 2015, claiming that it operates "under the auspices of ISIS," and that it hacked "Pentagon networks." It announced:
While the US and its satellites kill our brothers in Syria, Iraq and Afghanistan 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. With Allah's permission we are in CENTCOM now. We won't stop! We know everything about you, your wives and children. U.S. soldiers! We're watching you!
Before CENTCOM's primary and Russian-language Twitter accounts were suspended, the "CyberCaliphate" posted on them images of some of the documents and the link to access the Pastebin page. The page included links to download two Rar archive files, one containing PowerPoint presentations in a folder called "war scenarios," and the other containing 16 PDFs and one Word document about army budgets, forces, and officers.
The group also tweeted from CENTCOM's Russian Twitter account two lewd images of a woman, with the post reading: "We know everything about your wives."
In addition to these alleged hacks, the "CyberCaliphate" claimed hacking the FBI and posted a link on January 12 to download allegedly stolen files.
