World War 2.0, a news video on Wired Science, presents the realities of internet warfare and how a botnet attack against Estonia might have been a manifestation of this new war technique. Botnets are so powerful, and hackers are very skilled and experienced that they can "destroy servers of a whole state." Josh Davis traced back when the attack against Estonia started and how security officials in Estonia fought back. Bill Woodcock, founder of Packet Clearing House, provides a brief explanation on how a botnet operates and how the attack against Estonia happened. Jaak Aaviksoo, Estonian Defense Minister, Ago Väärsi, technical manager at Postimees.ee, and Hillar Aareland, head of the Estonian CERT, were also interviewed as well as Russian internet security expert Emin Azizov and IT director of the United Civilian Front Eugeni Grigorian.
