What Washington, D.C., calls a hacker attack on government computer systems, in a cyberwar the offensive force picks the battlefield, and the other side may not even realize it's under attack. Just as with e-anything and i-anything, we are also seeing the use of "cyber-anything" (including cyberguerrilla, cybercop, and so on). These terms are usually used by journalists to create a sensation, but cyberwars are legitimate and can be very destructive.
For example, China denied reports that Chinese "cyberspies" had stolen sensitive data from thousands of computer across the world. An April, 2009 report by the Information Warfare Monitor, a Canadian watchdog group, said a Chinese spy ring had hacked classified documents from governments and organizations in 103 countries, including the Dalai Lama's private files! The group said the hackers could take complete control of computers, even activating microphones and cameras to spy on people in the vicinity.
