Seems that cyber warfare becomes a constant in armed conflicts between countries like it happened in the last few days in Georgia. When Arbor Networks' Jose Nazario noticed data streams containing strings like 'win+love+in+Russia' and DDOS attacks started as early as July 20, this was just a test run for worse things to come, including web site defacements and a general inavailability of Georgia's Internet infrastructure. The role of Russian telecommunications firms that hosted servers involved in the attacks (or at least that contributed to the general propaganda) is yet to be analyzed. With estimated costs of 4 cents per attacking machine, this kind of attack will be seen more often, especially against countries whose infrastructure depends on the Internet. (Source)
