A Distributed Denial-of-Service(DDoS), one of the simplest and most powerful cyber attacks is a big problem nowadays. It has existed since the past, but now attackers can give greater damage to their target due to the development of more effective attack techniques and the propagation of high-speed internet and so on. Especially DDoS attack is now getting a huge problem because the unspecified individuals(called zombie PCs) are used in loading malicious codes while attacking a single site or system. DDoS attack is directly related to targeted companies, institutions and even governments, security companies and users as well. Plus, there is a possibility of running malicious code onto many other types of electronic devices such as smart phones, game consoles, home appliances and even cars. Therefore a new type of DDos attack might be seen in various places. In this presentation, we will figure out the large-scale DDoS attacks occurred in Korea(July 2009, March 2011) with detailed analysis and reverse tracking and how defenders(Korean institutions and security companies) coped with the attack. WE WILL NOT MENTION WHO THE ATTACKER IS. Also we will show the new type of DDoS attacks (by PC, smart phone, game console and so on) through demonstration. In this demonstration, we will handle the mechanism of DDos attacks including the type of attack, damage and preparation stage as well. Finally, we will suggest a solution of this problem. *IMPORTANT* This presentation tries not to include boring stuff. It will be fun with easy explanation and interesting demonstration.
