Over the last couple of years a range of privacy threats have been in occurring. Europe is starting to look like the playing field of what is to come to the US: Storage of all e-mail traffic, online presence, phone calls, actual traveling throughout nations and filtering of content. Fortunately a closer look at the measures shows that it is never smart to overestimate the abilities European governments have and digital self defense is possi....
This talk was given by Brenno de Winter in place of the much talked about canceled talk : The Anatomy of a Subway Hack:Breaking Crypto RFID's and Magstripes of Ticketing Systems by the original authors: Zack Anderson,Student, MIT RJ Ryan,Student, MIT Alessandro Chiesa,Student, MIT Original Summary & Bio's: In this talk we go over weaknesses in common subway fare collection systems. We focus on the Boston T subway, and s....
Much literature has addressed the issue of the relative sizes of shadow economies in different countries. What is largely missing from this discussion is a more structured discussion on how to incorporate estimates of shadow economic activity into the national income accounting framework and a discussion of how the shadow components of specific industries can be analyzed in either an input-output or macroeconomic framework. After a brief di....
Over the last several years, we've seen a decrease in effectiveness of "classical" security tools. The nature of the present day attacks is very different from what the security community has been used to in the past. Rather than wide-spread worms and viruses that cause general havoc, attackers are directly targeting their victims in order to achieve monetary or military gain. These attacks are blowing right past firewalls and anti-virus an....
The market share for Apple devices has grown considerably over the past few years, but most reverse engineering topics still focus on Microsoft platforms. This talk will outline what is necessary to begin reversing software on OS X. This will include a rundown of the tools available to an apple based researcher, how Objective-C works and what it looks like in a binary, the basics of the Mach-O file format including the undocumented _OBJC se..
This presentation describes how attackers could take advantage of SQL Injection vulnerabilities using time-based blind SQL injection. The goal is to stress the importance of establishing secure development best practices for Web applications and not only to entrust the site security to the perimeter defenses. This article shows exploitation examples for some versions of Microsoft SQL Server, Oracle DB Engine,MySQL and Microsoft Access datab....
A major drawback with the use of most reverse engineering tools is that they were not designed with collaboration in mind. Numerous kludgy solutions exist from asynchronous use of the same data files to working on multiple copies of data files which quickly diverge leaving the differences to somehow be reconciled. Pedram Amini's Ida Sync provided a first step towards automated collaboration among Ida users however Ida Sync suffers from seve....
This presentation is intended for individuals with an understanding of the Intel 8051 and Motorola 6805 processor families from an Assembly language perspective. This will be an interactive presentation with the audience. Log files will be examined that have been taken from the targets (smartcards) at every clock cycle of the CPU during its runtime. We will discuss our possibilities and determine points in time (clock cycle periods) to....
This talk discusses privacy issues concerning Adobe Flash Local Shared Objects. Adobe LSOs are similar to HTTP cookies, but not as easily controlled or configured using a standard web browser. Potential problems with Flash LSOs will be presented, as well as suggestions for increasing privacy while using Adobe LSOs. Clinton Wong published HTTP Pocket Reference and Web Client Programming with Perl. He works in Silicon Valley.
It's past time for a session layer. It's time to replace port knocking with a real authentication framework. It's time to do what DNS did with IP addresses to port numbers. It's time to run services over NATs, eliminate the need for vhosts in your webserver and provide optional transparent encryption for any client who wants it. In this talk, we'll do that and a couple other tricks... within the framework of a little-known RFC that was writ....
DNS is at the heart of every network -- when a web site is browsed to, it says where the site is, and when an email is sent, DNS says where to. The answer is usually correct -- but not always. Six months ago, it became clear that there was an ancient design flaw, present in the original 1983 specification for DNS, that would allow any attacker to insert their own addresses for DNS names. An industry wide bug hunt commenced, culminating in a..
While commercial web application scanners have been available for quite a while, the selection of open source tools has been limited. Grendel-Scan is a new tool that aims to provide in-depth application assessment. Written entirely in Java and featuring an easy to use GUI, the tool is intended to be useful to a wide variety of technical backgrounds: from IT security managers, to experienced penetration testers. Grendel-Scan can test fo....
Security is getting better; there is no doubt about that. High value targets are increasing their security while buying into the buzzword hype with phrases like "defense in depth". Firewalls, IPS, AV, NAC, and a host of other technologies have done a lot to give the pointy hair bosses of the world the ability to sleep easy...or has it. While those PHB sleep easy in their bed the ability to compromise a site at will continues to grow. R....
This presentation will detail the newest developments in RE:Trace, a reverse engineering framework based on Ruby and DTrace. We will discuss implementations for walking and searching the heap on OS X, tracing for kernel and driver vulnerabilities, pinpointing format string bugs and leveraging custom application probes, such as those built into browser and database software. David Weston is security researcher and penetration tester at ....
Stories about the loss of sensitive data are becoming more common, and an untold number of others probably are not known because they were not covered by law or did not get the attention of regulators. A loss may happen when data is stolen or simply lost, or when a system is breached. Existing federal and state laws cover specific industries and prescribe particular responses, but pending legislative proposals threaten to expand coverage si....
Security-related laws and regulations, with parallel privacy measures, are assuming an ever-expanding role in American society. As a result, the likelihood that an organization will receive a call, visit, subpoena, or letter from a law enforcement agency is constantly increasing. This program will address issues related to addressing these contacts. It will explore relevant legal questions but also the real world processes and consideration....

Your stack is smash-proof. Your dumpster is fully alarmed. And your firewall is so secure that it has former Soviet officials green with envy. So why are the developers finding their undocumented features in competitors' products, or company executives on a constant hunt for leaks and traitors? There's a whole lot more to doing an end-run around network security than calling up and pretending to be the help desk or hoping someone chucks a s..
In less than an hour, during a scheduled pentest, our team was able to retrieve 3.2 million patient insurance records from a HIPAA-compliant medical facility. Using these records, we could have generated counterfeit insurance and prescription cards which would pass muster at any doctor's office or pharmacy counter. If you are one of the 47 million Americans with no health insurance or happen to have a medical condition you wished to hide fr....
How fast a port-scan can be is largely dependent on the performance of the network in question. Nonetheless, it is clear that choosing the most efficient scanning-speed is only possible based on sufficient information on the network's performance. We have thus designed and implemented a port-scanning method which provokes extra network-activity to increase the amount of information at our disposal in an attempt to gain speed on the long run....
Thanks to Web 2.0 and other over hyped BS, development has been moving farther and farther away from bare metal. Assuming you trust your libraries, this could even be called a good thing. If you're high." PC gaming, despite Microsoft's best efforts, is not dead. Yet. The modding community is alive and active, and even those same over hyped web technologies are starting to encroach in to shaders, and other things they shouldn't touch. L....
Recent developments such as the FBI operation "Cisco Raider" that resulted in the discovery of 3,500 counterfeit Cisco network components show the growing concern of U.S. government about an electronic hardware equivalent of a "Trojan horse". In an electronic Trojan attack, extra circuitry is illicitly added to hardware during its manufacture. When triggered, the hardware Trojan performs an illicit action such as leaking secret information,....
Attacks on network infrastructure are not a new field. However, the increasing default protections in common operating systems, platforms and development environments increase interest in the less protected infrastructure sector. Today, performing in-depth crash analysis or digital forensics is almost impossible on the most widely used routing platform. This talk will show new developments in this sector and how a slightly adjusted net....
The talk focuses on 1D and 2D barcode applications with interference possibilities for the ordinary citizen. Ever wondered what is in these blocks of squares on postal packages, letters and tickets? Playing with them might have interesting effects, reaching from good old fun to theft and severe impact. Barcodes have been around for ages, but most of the time were used as simple tags with a number. The rise of 2D barcodes started to put....
The Nmap Security Scanner was built to efficiently scan large networks, but Nmap's author Fyodor has taken this to a new level by scanning millions of Internet hosts as part of the Worldscan project. He will present the most interesting findings and empirical statistics from these scans, along with practical advice for improving your own scan performance. Additional topics include detecting and subverting firewall and intrusion detection sy....
Take a trip back in time and discover what hacking was like in the pioneer days -- before the Internet, the PC, or even the Commodore 64 or TRS-80. The speaker started "exploring" computer systems in 1973, when the only law about hacking was the hacker ethic itself. Join a humorous reminiscence about what it was like building an Altair 8800, "discovering" the 2600 Hz tone, storing programs on punched cards, cracking bad crypto, and more. Yo..
Every time we use the web, we disclosure tremendous amounts of information to ISPs, Internet backbone providers, and online companies; information that will be shared and data mined, but rarely discarded. Email addresses, phone numbers, aggregated search queries, cookies, IP addresses - any unique feature of our behavior provides a mechanism to link, profile, and identify users, groups, and companies. From these revelations all aspects of o....
Cable modems are widely used these days for internet connections or other applications. This talk gives a detailed overview of this mean of communication with a focus on its security. DOCSIS (Data Over Cable Service Interface Specification) is currently the most used protocol around the world for providing internet over TV coaxial cable. Due to its nature, this protocol can easily be sniffed by taping onto the TV cable using a digital ....
In this talk Professor Angell will take the Devils advocate position, warning that computer technology is part of the problem as well as of the solution. The belief system at the core of computerization is positivist and/or statistical, and that itself leads to risk. The mixture of computers and human activity systems spawns bureaucracy and systemic risk, which can throw up singularities that defy any positivist/statistical analysis. Using ....
What do you want? This is the question that almost every commercial organization on the planet thinks they have an answer to, but do they? Figuring out what people want is essentially a process of reverse engineering human needs, desire, and preference. It turns out that hackers are particularly adept at reverse engineering, so what happened when we applied our skills to reverse engineering what you, and everyone else, wants? This talk....
This session will discuss the risks associated with creation of replicating code. A combination of wide availability of virus source code as well as the problem of control over replicating code make these experiments quite risky. To demonstrate these points we shall see how a computer virus was once created unintentionally in a self-modifying tool called ALREADY.COM (we'll disassemble and debug it). We shall watch a video of the "Corrupted ....
This talk will reintroduce classic steganographic techniques to use with serializing, watermarking, or stashing your data in the latest Internet meme. Why not let everyone who is forwarding yet another painful nut-shot AFHV clip store your data for you? We will create a simple filesystem that is robust enough to survive conversion, and building a structure to organize the data, focusing on indirection and fault tolerance. Jim has over ..
In order to prevent music from being copied among consumers, content providers often use DRM systems to protect their music files. This talk describes the approach taken while analysing a DRM system (whose identity needs to be kept secret due to legal issues). It is shown what techniques were used to protect the system from being easily reverse engineered. This is not about how to hack $Insert_DRM_Here. No decryption tools or information on..
For the past 3 years, Jason Scott (creator of BBS: The Documentary) has been working on another project, telling the history and the legends of text adventure games. 80 interviews later, he comes to DEFCON to show footage, describe the process of making the film, why history of games is important, and what it was like to visit the actual cave the first adventure game was based on. Jason Scott is celebrating 10 years of running his comp..
In the face of far stronger firewall and IPS-protected perimeters,attackers are compromising far more systems by hacking our web browsers, e-mail clients, and office document tools. Unfortunately,vulnerability assessment practices still focus on checking listening services, even on workstations. Detecting vulnerable clients is left for patch management tools, which aren't in consistent or wide enough use. Even when organizations are able to....
This talk introduces a new open source, plugin-extensible attack tool for exploiting web applications that use cleartext HTTP, if only to redirect the user to the HTTPS site. We'll demonstrate attacks on online banking as well as Gmail, LinkedIn, LiveJournal and Facebook. We'll also compromise computers and an iPhone by subverting their software installation and update process. We'll inject Javascript into browser sessions and demonstrate C....
How much data do you generate in the process of living an ordinary day? This talk covers various ways to gather, persist and analyze the data stream that is your life. We'll cover a few of the approaches that are available today, some easy code you can whip up to persist anything you please, and what to expect from the community and businesses moving forward. Privacy/security impact is sure to be huge, so hold on to your hats, and start tra..
Have you gone to school? Are you going to school? Do you work at a school? How do you prove you went to a particular high school, college or university? FACT: Educational institutions MUST keep your personal/confidential information. Therefore, your personal/confidential information might be at risk! This presentation will be about typical software packages found at educational institutions and their vulnerabilities. We will use known attac....
We like hardware and we like messing with people. BSODomizer lets us do both. BSODomizer is a small propeller-based electronic device that interfaces between a VGA output device (laptop or desktop) and VGA monitor and will flash images at random time intervals. (Surprise Goatse!) Or display your favorite BSOD causing the confused user to turn off their machine over and over again. Customization for different modes are configurable via on-bo....
The legal community is slowly accepting that the changes to the Federal rules which change the law's approach to electronic evidence are not going away. Vendors are clamoring to sell their e-discovery "solutions" to law firms and corporations alike, often taking advantage of the uncertainty that comes with such sweeping changes to the law. The changes to the Federal Rules change the way in which individuals and organizations approach t....
Own the VMware box and you get half the servers on the network for free. Although, depending on the VMware server's configuration, whether you want to be stealthy about it and whether you want to avoid any disruption it may not always be quite that simple. During this talk we will take a look at ways of jumping from a server to guest OS without causing any disruption and also some tools for assessing the security posture of VMware products.....
Pre-boot authentication software, in particular full hard disk encryption software, play a key role in preventing information theft. In this paper, we present a new class of vulnerability affecting multiple high value pre-boot authentication software, including the latest Microsoft disk encryption technology : Microsoft Vista's Bitlocker, with TPM chip enabled. Because Pre-boot authentication software programmers commonly make wrong assumpt....
