malware DoS Event:
Black Hat Abu Dhabi 2011 Abstract: 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.

router exploiting Cisco Event:
Hashdays 2010 Abstract: The talk demonstrates, based on Cisco devices, that DDoS attacks, spam and viruses are not only coming from the "normal suspects" (PC, server and mobile devices). There are other devices, like routers or switches, which can do the same. All these devices are becoming more and more "intelligent" and have "features", which will make it possible to realize all kinds of attacks. Because of broad distribution of all these feature packed devices to the customer, these devices have a greater potential for misuse and will in the future become more in focus of hackers.

DDoS DoS Event:
Black Hat DC 2011 Abstract: Denial-Of-Service is an attempt to make a computer resource unavailable to its intended users and is not new. In recent history April 2009, government and financial sites in the U.S. and South Korea were attacked by DDOS and were brought offline for days. This incident followed the Georgian DDOS attacks in 2008 and Estonian DDOS attacks in 2007. Common attack methods include systems infected with malware that are controlled and all connect to the target host at the same time using Layer 4 (Transport) which are already addressed by anti-DDOS solutions when employed. In 2009 a lethal form of Layer 7 (Application) attack techniques were being examined by Wong Onn Chee of OWASP Foundation Singapore and in 2010 together with Tom Brennan of OWASP Foundation presented the findings publicly for the first time with code samples. Tom Brennan will walk through the history and details of how this lethal HTTP POST DOS technique works, interesting findings in the protocol and the challenges in defending critical infrastructure against targeted attacks and demonstrate and release his open-source tool that can be used to test your own production systems -- or render others useless with the touch of a button from a single laptop.
