The U.S. Department of Defense has long advocated going on the offensive against criminal gangs and foreign governments that seek (and often succeed) to penetrate U.S. government and military Internet security, and steal information, or sabotage operations. Without much fanfare, the Department of Defense has made preparations to do just that.
Since the military cannot afford to pay enough to recruit qualified software and Internet engineers for this sort of work, it has turned to commercial firms. There are already some out there, firms that are technically network security companies, but will also carry out offensive missions (often of questionable legality, but that has always been an aspect of the corporate security business.)
Some of these firms have quietly withdrawn from the Internet security business, gone dark, and apparently turned their efforts to the more lucrative task of creating Cyber War weapons for the Pentagon.
