Due to the prevalence of spammers on the internet CAPTCHAs have become a necessary security measure. Without a CAPTCHA in place a system is incapable of knowing whether a human or an automated computer is executing a request. Currently one of the most widely implemented versions of this system is Google's reCAPTCHA due to its robustness thus far. This paper illustrates techniques to defeat this system which has been trusted to secure websit....
Think you might ever be "asked" by a dictator of an Axis of Evil country to take down the USA in a cyberwar? Ever wonder how someone who finds vulnerabilities and breaks into computers for a living would approach cyberwar, i.e. not Richard Clarke? Then this is the talk for you! In this talk, I outline how to construct a cyber army to attack a developed country, based on my experience as a penetration tester and security researcher. This wil....
This session is about Parameter Pollution in Connection Strings Attack. Today, a lot of tools and web applications allow users to configure dynamically a connection against a Database server. This session will demonstrate the high risk in doing this insecurely. This session will show how to steal, in Microsoft Internet Information Services, the user account credential, how to get access to this web applications impersonating the connection ....

FOCA is a tool to extract information in footprinting and fingerprinting phases during a penetration test. It helps auditors to extract and analyze information from metadata, hidden info and lost data in published files. This new release of FOCA, version 2, adds tools to scans internal domains using PTR Scanning, Software recognition through installation paths, etc. The idea of FOCA is to give as much info as can be discovered automatically....

Facebook's privacy issues are numerous and well-documented, from software "glitches" to decisions that take control away from users. Despite that, it is a still-growing force in the modern Internet and is currently trying to position itself as the gateway to the "social Web" for its 500 million users. What can we, as hackers, do to protect the privacy of those millions? This panel walks through a few existing projects that apply s....
If you think that RFID tags can only be read a few inches away from a reader you haven't met EPC Gen2, the tag that can be found in Enhanced Drivers Licenses - this 900MHz tag is readable from 30 feet with off-the-shelf equipment. Without amplifying the signal from a commercial reader we were able to equal the previous Defcon record of 69 feet, and with less than $1000 of equipment we achieved considerably further than that. This talk cover....

It's widely accepted that the cryptoscheme in GSM can be broken, but did you know that if you're within radio range of your target you can intercept all of their cellphone calls by bypassing the cryptoscheme entirely? This talk discusses the practical aspects of operating an "IMSI catcher", a fake GSM base station designed to trick the target handset into sending you its voice traffic. Band jamming, rolling LACs, Neighbour advertisements an....

Your Internet, phone and web application providers are all, for the most part, in bed with the government. They all routinely disclose their customers' communications and other private data to law enforcement and intelligence agencies. Worse, firms like Google and Microsoft specifically log data in order to assist the government, while AT&T and Verizon are paid $1.8 million per year in order to provide real time access to customer communica....

This talk will demonstrate how many consumer routers can be exploited via DNS rebinding to gain interactive access to the router's internal-facing administrative interface. Unlike other DNS rebinding techniques, this attack does not require prior knowledge of the target router or the router's configuration settings such as make, model, internal IP address, host name, etc, and does not rely on any anti-DNS pinning techniques, thus circumvent....
Lets be honest: Year in, year out, we keep finding the same bugs in the same places, and wondering: Why don't they learn? Why don't developers use these beautiful tools we provide them -- parameterized queries, XSRF tokens, X.509 certificates, and escapes in all their glorious forms? I will tell you: It is because these tools are not very good. And they are not very good, because their quality simply has not mattered. Security demands, devs....

Our world is instrumented with countless sensors. While many of these are outside of our control (at least without significant effort...) there is an incredible amount of publicly available information being generated and gathered all the time. While much of this data goes by unnoticed or ignored it contains fascinating insight into the behavior and trends that we see throughout society. The trick is being able to identify and isolate the u....

For the fifth year in a row, the DEFCON Badge makes its appearance as a full-fledged, active electronic system. Pushing fabrication techniques to the limit and using some components that are so new they barely exist, the design of this year's badge took some serious risks. Did they pay off? If you're in this talk and not standing in a long line to get your badge, then the answer is "Yes!" Join Kingpin as he guides you through the entir..
Hardware hacking is cool, but it can be daunting to software guys. Microcontrollers mix hardware and software basically allowing software guys to do hardware in software. Lately several products have emerged that make it even easier for software guys to get hardware up and working. Arduinos are relatively cheap, open source, all-in-one prototyping boards with a strong community behind them. All you need is a USB cable and the Ardu....

Using cloud computing to attack systems allows for the testing of a company's incident response and recovery program. We have been using the cloud computing environment to test real world scenarios for different types of attacks, such as Distributed Denial of Service, Flooding, and Packet Fragmentation. The presentation will review some of the common attack types, what they are, and how they can be used to disrupt service. I will also revie....

Imagine the following experiment, a unique case is given to three digital forensic analysts and each is given the opportunity to engage the requester in order to develop the information needed to process the case. Based on the information gathered, each of the three analysts is asked to provide an estimate to complete the investigation and can proceed with up to 20 hours to process the case. The analysts are then measured based on the total....
