WASHINGTON (AP) - The military's top cyber warrior says he is confident that foreign leaders are deterred from launching an electronic attack on vital infrastructure in the United States because they know such a strike could be traced to its source and would generate a robust response.
But Army Gen. Keith Alexander, head of U.S. Cyber Command, told a Senate committee Tuesday the country is not preventing what he called low-level harassment of private and public web sites, property and information by other states. He did not mention any specific countries.
Offensive cyber weapons are growing and evolving, Alexander said, and it is only a matter of time before tools developed by other nations wind up in the hands of extremist groups or even individuals who could cause serious damage and disruption.
