qualification by motivation, targets, methods, and centrality of computer use in the act. U.S. government agencies also use varying definitions and that none of these have so far attempted to introduce a standard that is binding outside of their sphere of influence. Depending on context, cyberterrorism may overlap considerably with cybercrime, cyberwar or ordinary terrorism. Eugene Kaspersky, founder of Kaspersky Lab, now feels that "cyberterrorism" is a more accurate term than "cyberwar". He states that "with today's attacks, you are clueless about who did it or when they will strike again. It's not cyber-war, but cyberterrorism." He also equates large-scale cyber weapons, such as the Flame Virus and NetTraveler Virus which his company discovered, to biological weapons, claiming that in an interconnected world, they have the potential to be equally destructive. If cyberterrorism is treated similarly to traditional terrorism, then it only includes attacks that threaten property or lives, and can be defined as the leveraging of a target's computers and information, particularly via the Internet, to cause physical, real-world harm or severe disruption of infrastructure. Many academics and researchers who specialize in terrorism studies suggest that cyberterrorism does not exist and is really a matter of hacking or information warfare. They disagree with labeling it as terrorism because of the unlikelihood of the creation of fear, significant physical harm, or death in a population using electronic means, considering current attack and protective technologies. If death or physical damage that could cause human harm is considered a necessary part of the cyberterrorism definition, then there have been few identifiable incidents of cyberterrorism, although there has been much policy research and public concern. Modern terrorism and political violence is not easily defined, however, and some scholars assert that it is now "unbounded" and not exclusively concerned with physical damage. There is an old saying that death or loss of property are the side products of terrorism, the main purpose of such incidents is to create terror in peoples' minds and harm bystanders. If any incident in cyberspace can create terror, it may be rightly called cyberterrorism. For those affected by such acts, the fears of cyberterrorism are quite real. As with cybercrime in general, the threshold of required knowledge and skills to perpetrate acts of cyberterrorism has been steadily diminishing thanks to freely available hacking suites and online courses. Additionally, the physical and virtual worlds are merging at an accelerated rate,
