Evil DoS Attacks Techniques and How to build a Strong Defenses

https://www.youtube.com/watch?v=scBSr6T_6uc
On the attack side, this talk will explain and demonstrate attacks which crash Mac OS X, Windows 8, Windows Server 2012, and Web servers; causing a BSOD or complete system freeze. The Mac and Windows systems fall to the new IPv6 Router Advertisement flood in thc-ipv6-2.1, but only after creating a vulnerable state with some "priming" router advertisements. Servers fail from Sockstress--a brutal TCP attack which was invented in 2008, but still remains effective today. On the defense side: the inside story of the DDoS that almost Broke the Internet. In March 2013, attackers launched an attack against Spamhaus that topped 300Gbps. Spamhaus gave us permission to talk about the details of the attack. While CloudFlare was able to fend off the attack, it exposed some vulnerabilities in the Internet's infrastructure that attackers will inevitably exploit. If an Internet-crippling attack happens, this is what it will look like. And here's what the network needs to do in order to protect itself. Sam Bowne (@sambowne) has been teaching computer networking and security classes at CCSF since 2000. He has given talks at DEFCON, BayThreat, LayerOne, Toorcon, and lightning talks at HOPE on Ethical Hacking, and taught classes and seminars at many other schools and teaching conferences. He has a PhD & lot of industry certs but still no CISSP. Matthew Prince (@eastdakota) is the co-founder & CEO of CloudFlare, the web performance and security company. Matthew wrote his first computer program at age 7 when his mom would sneak him in to university computer science courses. After attending law school, he worked as an attorney for one day before jumping at the opportunity to be a founding member of a tech startup. He hasn't looked back. CloudFlare is Matthew's third entrepreneurial venture. CloudFlare was named a 2012 Technology Pioneer by the World Economic Forum and selected by the Wall Street Journal as the Most Innovative Internet Technology company for the last two years running. Today, CloudFlare accelerates and protects more than 120 billion page views for over a million customers and more than 1.5 billion web visitors every month. Matthew holds a degree in English and Computer Science from Trinity College. He graduated with highest honors from the Harvard Business School where he was a George F. Baker Scholar and was awarded the Dubliner Prize for Entrepreneurship. He earned a JD from the University of Chicago and is a member of the Illinois Bar. He teaches technology law as an adjunct professor at the John Marshall Law School where he serves on the Board of Advisors for the Center for Information Technology and Privacy Law. He is also the co-creator of Project Honey Pot, the largest community of webmasters tracking online fraud and abuse. On the side, Matthew is a certified ski instructor, a former mountain guide, and a regular attendee of the Sundance Film Festival By Emmanuel Akpan (For more information you can visit our main website to see more Tutorials - http://www.socialwebng.com)

Extracting Data from Difficult Websites

https://www.youtube.com/watch?v=UiOSEhDT7Pc
Screen scrapers and data mining bots often encounter problems when extracting data from modern websites. Obstacles like AJAX discourage many bot writers from completing screen scraping projects. The good news is that you can overcome most challenges if you learn a few tricks. This session describes the (sometimes mind numbing) roadblocks that can come between you and your ability to apply a screen scraper to a website. You'll discover simple techniques for extracting data from websites that freely employ DHTML, AJAX, complex cookie management as well as other techniques. Additionally, you will also learn how "agencies" create large scale CAPTCHA solutions.

internet censorship, how to defeat internet censorship, bypassing internet filters,

The greatest danger to free speech on the Internet today is filtering of traffic using protocol fingerprinting. Protocols such as SSL, Tor, BitTorrent, and VPNs are being summarily blocked, regardless of their legal and ethical uses. Fortunately, it is possible to bypass this filtering by reencoding traffic into a form which cannot be correctly fingerprinted by the filtering hardware. I will be presenting a tool called Dust which provides an engine for reencoding traffic into a variety of forms. By developing a good model of how filtering hardware differentiates traffic into different protocols, a profile can be created which allows Dust to reencode arbitrary traffic to bypass the filters. Dust is different than other approaches because it is not simply another obfuscated protocol. It is an engine which can encode traffic according to the given specifications. As the filters change their algorithms for protocol detection, rather than developing a new protocol, Dust can just be reconfigured to use different parameters. In fact, Dust can be automatically reconfigured using examples of what traffic is blocked and what traffic gets through. Using machine learning a new profile is created which will reencode traffic so that it resembles that which gets through and not that which is blocked. Dust has been created with the goal of defeating real filtering hardware currently deployed for the purpose of censoring free speech on the Internet. In this talk I will discuss how the real filtering hardware work and how to effectively defeat it.

WPA2 is the most robust security configuration available today for WiFi networks. It is widely used to secure enterprise WLANs. Interestingly, it is also being used to secure guest, municipal and public WiFi networks. In this paper, we present a new vulnerability found in WPA2 protocol which can be exploited by a malicious user to attack and compromise legitimate users. We also present a few attack mitigation techniques which can be used to protect genuine WiFi users.
