CNET reports: "Flash mobs may have been responsible for those denial-of-service (DoS) attacks in Estonia last May. So says Gadi Evron, security evangelist for Beyond Security, who gave a thorough presentation last week at Black Hat and then again at Defcon, recounting in detail the events surrounding the attack, some of which he experienced first-hand, surrounding the attack. Although he originally joked that the KGB was to blame--and quickly explained that the KGB no longer existed--Evron said could not prove conclusively that the Russians were behind the events. Yet he did call it the first true cyberwar, if only that the commerce and day-to-day functions of one country were interrupted significantly."
This article really makes you think how any country these days could be effected by cyber-warfare.
