The Islamic State seems to have a hacking division, and it has published the details of 1,400 military and government personnel, from the U.S. as well as Australia.

Published online on Wednesday, the spreadsheet contains names, email addresses, phone numbers and passwords of officials of the Marine Corps, NASA, the state department, Air Force and FBI. Australian Counter-Terrorism Minister Michael Keenan confirmed that details of eight Australians had been compromised.

A spokesperson for the IS told the Guardian that the information was obtained from military and government databases.

But the U.S. military denied the claims.

"This is the second or third time they've claimed that and the first two times I'll tell you, whatever lists they got were not taken by any cyber attack," U.S. Army Chief of Staff Gen. Ray Odierno said, according to The Guardian. "This is no different than the other two," he said, referring to so-called hacks by IS in January and May. "But I take it seriously because it's clear what they're trying to do ... even though I believe they have not been successful with their plan." 

The spreadsheet was accompanied by a message that read, "Know that we are in your emails and computer systems, watching and recording your every move, we have your names and addresses, we are in your emails and social media accounts. We are extracting confidential data and passing on your personal information to the soldiers of the khilafah, who soon with the permission of Allah will strike at your necks in your own lands!" reports The Daily Mail.

Neil Prakash, Australia's top IS fighter, sent the list to his 1,100 followers and urged them to attack, saying, "Kill them where you find them and enslave their women," according to The Herald Sun.
