[PANEL] After Napster: The Inevitable Ascent of Peer-to-Peer Networks, LiveHives, Smart Mobs and Massive Subscription File-Sharing Services

From Napster to the current emerging techno-social phenomena of livehives and smart mobs, the evolution of peer-to-peer networks is exhibiting an exponential profligacy both in use and popularity, and actually influencing the evolution of human social interaction on both a local and a global scale.

Beginning with Napster, the popular Internet file sharing software created in 1999 by Shawn Fanning, arguably a revolution has taken place.
Napster was at the forefront of the one of the most important electronic debates of the 20th century’s fin-de-siecle: DMCA and various attendant copyright debates.

However, the perhaps the most important role that Napster played was as a “proof of concept” on a grand scale (98 million globally at it’s peak) of the power of peer-to-peer communications.

Wireless data communication devices have screamed onto the networking scene in and may be poised to revolutionize social intercourse. Blogger journos can instantly upload text, audio, and video to their weblogs from the scene of breaking news events. With conventional cellular telephones tactical organization of crowds, “smart mobs,” can be coordinated in political actions.. The newest breed of communication technologies can document in real-time documentation of an event without the need to rely on traditional media reports.

In “proof of concept” exercises, recent anti-war protests have utilized “livehive” and “smart mob” technologies to out flank police actions and effectively shut down city centers and targeted economic targets. “After Napster” will follow the evolution of peer-to-peer networks and their evolution as social communities of affording a new level of global awareness and action.

Revolutionizing Operating System Fingerprinting

Xprobe is an active operating system fingerprinting tool, which was officially released two years ago at the Blackhat briefings USA 2001. The first version of the tool was a proof of concept for the methods introduced in the “ICMP Usage in Scanning” project, which I have conducted. Two years after, and several versions later (mainly Xprobe2 v0.1 release), this talk would examine several issues with operating system fingerprinting we (Fyodor Yarochkin and myself) have encountered during the development of Xprobe and Xprobe2.

Mainly the talk will explain why traditional operating system fingerprinting methods suffer from a number of caveats, and how these issues directly affects the results different operating system fingerprinting tools relying on these methods produce (these issues will be explained along with different examples).

During the talk I will introduce several advancements in the field of operating system fingerprinting. The methods introduced greatly enhance the accuracy of operating system fingerprinting. Several new ways to gather information about a host OS will be uncovered along with ways to overcome many of the current issues of active operating system fingerprinting methods.

During the talk examples will be given, and the audience will be encouraged to participate in a discussion.

A paper release, and a new version of Xprobe2 will accommodate the talk.

Ofir Arkin is the founder of the Sys-Security Group, a non-biased computer security research and consultancy body.

Self-Abuse For Smarter Log Monitoring

Your Unix-based webserver has logs, and you know you should be keeping an eye on them. But what should you be looking for? Would you recognize an attack even if you saw one? What sort of automated log-watchers are available, and what if you need to tell *those* what to look for?

Attacking your own system while scanning its logs is a quick way to learn what anamolous log activity looks like. Plus, it's a fun excuse to run Nessus, nmap, and whisker against someone who won't call the cops on you (i.e., yourself). In my presentation I'll demonstrate this sort of productive self-abuse, using the aforemention tools plus less-glamorous but equally useful commands like telnet and wget. My groovy two-laptop demos will show both attacks and logged messages simultaneously, adding to the overall excitement.

In addition to all that, I'll discuss how to fine-tune the mechanisms that control logging, and how to use automated log-watchers such as swatch (which needs to be told what to look for) and logwatch (which doesn't necessarily).

The presentation will culminate in a challenging game of "You Be the K1d10t," in which Def Con attendees will be welcomed to take their best shot at my wireless-connected laptop, while the audience & I watch the log messages that result (or don't). Anybody who roots my box, or causes a really entertaining log message, will receive a piece of the donated junk arrayed on the stage for that purpose. (But if my box gets DoSed beyond salvage, I'll just ask some trivia questions and call it a day, so please play nice!)

This will be a fairly technical presentation. Attendees should have a
working knowledge of the Unix variant of their choice (my demo systems both run Linux), but my presentation should be comprehensible to most Unix newbies, while still being useful to intermediate and maybe even advanced users (hey, everybody knows different stuff).

Michael D. Bauer, CISSP, is Security Editor for Linux Journal, lead author of its monthly "Paranoid Penguin" security column, and an Information Security Consultant for Upstream Solutions in Minneapolis, MN. Mick's first book, "Building Secure Servers With Linux" was published by O'Reilly & Associates last October.

Locking Down Mac OS X

Apple's OS X operating system combines BSD Unix with easy-to-use Mac operating system components. This has produced an operating system that natively runs Microsoft Office, is friendly as can be finding you people with which to chat and exchange fileshares with, and yet still runs a command line! Needless to say, it could probably use some lockdown before you want to take it to Def Con, or even to the airport, with the wireless card plugged in.

The speaker has ported Bastille Linux to OS X and learned a thing or two about locking down OS X in the process. This talk will demonstrate lockdown, showing you how to harden the OS X operating system against future attack.

Jay Beale is a security specialist focused on host lockdown and security audits. He is the Lead Developer of the Bastille project, which creates a hardening script for Linux, HP-UX, and Mac OS X, a member of the Honeynet Project, and a core participant in the Center for Internet Security. A frequent conference speaker and trainer, Jay speaks and trains at the Black Hat and LinuxWorld conferences, among others.  A senior research scientist with the George Washington University Cyber Security Policy and Research Institute, Jay makes his living as a security consultant through Baltimore-based JJBSec, LLC.

Airsnarf - Why 802.11b Hotspots Ain't So Hot

As wireless hotspots continue to pop up around the country, the opportunity to take advantage of the weakest point of this new networking fad becomes greater. What weak point is that? Why, the user, of course. Why sniff traffic, or crack WEP, or spoof MACs, when you can simply ASK for and easily receive usernames and passwords? Members of the Shmoo Group discuss how wireless miscreants can garner corporate or hotspot credentials the easy way: rogue access points. Additionally, a new utility will be provided to make rogue AP setups a cinch--with a twist. Little to no wireless knowledge is needed to understand how simple it is to never again pay for wireless hotspot access.

Beetle is a member of the Shmoo Group, holds a BS in Computer Science, and is a D.C.-area computer security engineer. He is CEO of a Northern Virginia WISP, Vice President of the Capital Area Wireless Network, and licensed amateur racecar driver. His war-driving setup and adventures have been covered by The Washington Times, The Baltimore Sun, and NPR.

Toward a Criminal Law for Cyberspace

The traditional model of law enforcement was shaped by certain assumptions about criminal activity. These assumptions derive from characteristics of real-world crime, i.e., that victim and offender must be in physical proximity, that crime is limited in scale, that physical evidence will be found at a crime scene and that crime falls into identifiable patterns. These assumptions gave rise to a hierarchically-organized model which operates on the premise that crime is localized, i.e., occurs within a specific geographical area encompassed by a single set of national laws. The traditional model, in effect, assumes the primacy of nation-states as law enforcers.

Neither these assumptions nor the premise that crime is localized apply to cybercrime; cybercrime makes nation-states irrelevant. It evades the assumptions that shaped the traditional model and, in so doing, creates significant challenges for law enforcement. It is therefore necessary to devise a new approach for dealing with cybercrime, one that takes into account the distinctive characteristics of technologically-mediated crime.

Such an approach is evolving in the cybercrime task forces established pursuant to a mandate contained in the USA PATRIOT Act. Whereas the old model emphasized law enforcement’s reacting to completed crime, this approach emphasizes collaboration between potential victims and law enforcement in an effort to prevent cybercime. It also emphasizes lateral, networking arrangements in which law enforcement personnel often function more as consultants than as sole investigators. Clearly, a lateral, collaborative approach is a more advantageous strategy for dealing with cybercrime.

The problem is that individuals also need to be involved if this approach is to be effective. Currently, corporations and other entities are more likely to understand the need and have the resources to partner with law enforcement in an effort to implement cybersecurity. This is not generally true of individuals, but it may be possible to use new principles of criminal liability – modified rules of criminal law and imported, modified civil law rules – to create incentives for individuals to participate in such an approach.

Susan W. Brenner is NCR Distinguished Professor of Law and Technology at the University of Dayton School of Law, where she teaches Criminal Law, Criminal Procedure, a Cybercrimes survey course and a Cybercrimes Seminar.

Professor Brenner has spoken at numerous conferences, including Interpol’s Fourth International Conference on Cybercrimes in Lyon, Interpol’s Fifth International Conference on Cybercrimes in Seoul, the American Bar Association’s National Cybercrime Conference, the American Bar Association’s 2002 Annual Conference, the National District Attorneys Association’s National Conference, the National Association of Attorneys General’s cybercrime training program and the Hoover Institution’s Conference on International Cooperation to Combat Cyber Crime and Terrorism, held at Stanford University. She participated in the Økokrim Conference, “The Internet as the Scene of Crime,” held in Oslo and is one of a group of experts assisting with the European Commission – Joint Research Centre’s CTOSE project on electronic evidence; she also spoke on cybercrime legislation at the Ministry of the Interior of the United Arab Emirates. She is Co-Chair of the International Efforts Working Group for the American Bar Association’s Privacy and Computer Crime Committee, serves on the National District Attorneys Association’s Cybercrimes Committee and is Co-Chair of the National Institute of Justice - Electronic Crime Partnership Initiative’s Working Group on Law & Policy. Her internationally known website,, was featured on “NBC Nightly News.” She has published various articles dealing with cybercrime, including Toward a Criminal Law for Cyberspace: A New Model of Law Enforcement?, __ Rutgers Computer & Technology Law Journal ___ (2003), The Emerging Consensus on Criminal Conduct in Cyberspace, 2002 UCLA J.L. & Tech,, Computer Searches and Seizures: Some Unresolved Issues, 9 Michigan Telecommunications & Technology Law Review 39 (2002), and The Privacy Privilege: Law Enforcement, Technology and the Constitution, 7 Journal of Technology Law and Policy 123 (2002), She has also written chapters for several cybercrimes books.

Professor Brenner has published numerous law review articles and book chapters dealing with issues in criminal law and two books: Federal Grand Jury Practice (West 1996) and Precedent Inflation (Rutgers 1990). Her grand jury web site,, provides information on state and federal grand juries.

Before joining the University of Dayton faculty, Professor Brenner practiced with two firms--Shellow, Shellow & Glynn in Milwaukee and Silets & Martin in Chicago.

Opensource Kernel Auditing and Exploitation

For a period of up to 3 months in 2002, a part-time manual security audit of the operating system kernels in Linux, FreeBSD, OpenBSD, and NetBSD was conducted.

The aims of audit were to examine the available source code, under the presumption of language implementation bugs. Thus classic programming bugs, prevalent in the implementation language [C], exemplified in integer overflows, type casting, incorrect input validation and buffer overflows etc were expected. The initial introduction to auditing examined easily accessible entry points into the kernel including the file system and the device layer. This continued to an increased coverage and scope of auditing. From this work, identification of conjectured prevalent bug classes was possible. These results are in favour of the initial expectations; that bugs would be that in line of classical language bugs.

The results of this audit are surprising; a large [more than naively expected] number of vulnerabilities were discovered. A technical summary of these vulnerabilities will be treated in detail. Bug classes and [conjectured] less secure specific subsystems in the kernel will be identified. These conjectures support the the research of Dawson Engler's work in automated bug discovery in application to open-source kernel auditing.

Vulnerabilities after bug categorisation, are applied in the treatment of exploitation. The results are again surprising; exploitation sometimes being trivial, and primarily being highly reliable. The assumptions of exploitation difficulty, is conjectured to be a false belief due to lack of any serious focus on kernel auditing prior to this paper. This conjecture is supported by in-line documentation of kernel sources indicative of immediate security flaws.

Attack vectors are identified as a generalisation of bug classes. Risk management is touched upon to reduce the scope of attack, but is not the primary purpose of this paper.

Discussion is finally that of vendor contact, and the associated politics of vulnerabilities. First hand reports of acknowledgement times, problem resolution times and public dissemination policies are presented in candid. The author may be biased at this point, but it appears that in during this audit period, open-source holds up to the promise of security concern and responsibility in its community. Problem acknowledgement in at least one of the the cases presented is perhaps the fastest in documented history (less than three minutes).

The majority of the vulnerabilities discovered during the audit, were resolved and patched in co-operation with the open-source developers and community responsible for each respective operating system. A very large thanks must go to Alan Cox, Solar Designer and later followed by Dave Miller who made enormous efforts to continually resolve all issues uncovered.

Silvio Cesare has for many years, been involved in computer security and the many talented and lesser front page individuals behind it. In 2001, Silvio relocated from Australia to France to work in the development of managed vulnerability assessment, after the best part of the previous year in Australia establishing the legal requirements to make this possible. In 2002, he relocated again to the US, after cessation of product development in France. During the last months working in the US as scanner architect of the companies flagship MVA product, he spent his part time auditing open source operating system kernels. Silvio spoke at conferences in 2002, including CanSecWest on his reverse engineering work; for which he was at one time in negotiations for authoring a book on Unix Virus. After impending legal requirements to leave the US, Silvio returned back to Australia for 2003. During the current year, he has been quietly involved in Ruxcon, an Australian computer security conference, presenting the results of the previous years part-time auditing. Silvio spends his days currently in Australia as a System Administrator outside of industry interests in computer security.

What Hackers Need to Know about Post 9/11 Legal Changes

The Bush Administration's relentless assault on freedom and privacy online and offline hit the ground running with the Patriot Act in the immediate aftermath of 9/11, but hasn't slowed since then. While the terrorist acts had absolutely no relationship to computer hacking, hackers were a clear target in the Patriot Act and subsequent developments. The changes in the legal landscape are vast and wide, but anyone interested in computer security research, whether professionally or as a hobby, should have a basic understanding of the new world order. EFF was one of the broad coalition of groups that fought the Patriot Act -- its analysis comes up first in a Google search on the law -- and continues its work opposing all of its ugly brothers, sisters, cousins and stepchildren. The talk will focus on the portions of these laws and programs that affect hackers of all hat colors, including:

  • Changes in the Computer Fraud and Abuse Act
  • The expanded definitions of "terrorist" and "material assistance to terrorists" and what they may mean for toolmakers
  • All your logs are belong to us - the reduced provisions for subpoenas to ISPs and others who have information about you
  • What reduced judicial oversight,fewer checks and balances and more sharing among various cops means in practice
  • What Patriot II/DSEA holds in store
  • TIA, CAPPS II and other acronyms you should know about
  • How can you legally to better protect yourself and others.

Cindy Cohn is the Legal Director for the Electronic Frontier Foundation. She is responsible for overseeing the EFF's overall legal strategy. EFF has been actively involved in nearly all areas where civil liberties are impacted online. EFF has focused in the past few years on the challenge to the constitutional rights presented by recent changes and broad application of intellectual property laws, including Felten v. RIAA, Universal v. Reimerdes (2600 Magazine), Newmark v. Turner (ReplayTV is not a crime) and advising the criminal defense attorneys in U.S. v. Sklyarov. The EFF has also worked to preserve the right to anonymous speech online and continues to defend those accused of various offenses based upon their protected speech activities. In the aftermath of the attacks of September 11, 2001, EFF has returned to its roots, focusing on the issues of government surveillance and other traditional civil liberties online.

Ms. Cohn first became involved with the EFF over 7 years ago, when the EFF asked her to serve as the lead attorney in Bernstein v. Dept. of Justice, the successful federal court challenge to the U.S. export restrictions on cryptography. That case was the first to hold that source code was protected expression subject to protection under the First Amendment. The Bernstein case was one of the major catalysts for decision by the U.S. government in January, 2000, to dramatically loosen its restrictions on the export of encryption software.

Interface Design of Hacking Tools

Publicly available computer security tools are often great works of
technological expertise. A great deal of effort goes into the technical implementation, often at the expense of the user interface and overall user experience. Designed for all levels of expertise, this talk explores common user interface design techniques that will put a usable front end on computer security tools. A variety of tools will be examined and critiqued to illustrate and reinforce these techniques. Attendees will leave with an increased understanding of user interface and user experience design that they can apply to their own development projects to make them more effective.

Greg Conti is an Assistant Professor of Computer Science at the United States Military Academy. He holds a Masters Degree in Computer Science from Johns Hopkins University and a Bachelor of Science in Computer Science from the United States Military Academy.

More Embedded Systems

The talk focuses on more embedded systems - this time, looking into the mobile world of GSM as well. How can the infrastructures and protocols in the Internet enabled GSM world be used for attacks? This session will give you an introduction to the concepts of WAP and GPRS. Equiped with this knowledge, some interesting applications of these protocols will be presented. Of course, it also covers some funny things you can do with (against) mobile phones. The second part will show you the latest advancements in Cisco IOS exploitation. While Phenoelit showed you last year that it can be done, we will go on and show you this year that it can be done better, more reliable and more elegant.

FX of Phenoelit is the leader of the German Phenoelit group. His and the group's primary interests are in security implementations and implications of standards or less-known protocols, as shown on past DefCon conventions. FX works as a Security Solution Consultant at n.runs GmbH.

Embedded Reverse Engineering: Cracking Mobile Binaries

The embedded mobile market is headed for a day of reckoning when it will become the target of virus/trojan writers. To prepare for this, security experts must understand reverse-engineering fundamentals, as they apply to the pocket PC device, so they can research, investigate and understand the impact of malware and how to prevent it from spreading.

Unfortunately, when it comes to understanding malware for the PPC environment, there is little guidance. The only exception to this is ironically found in the backyard of same people who would write the destructive code. What we are talking about is the reverse-engineering of software protection schemes.

As a result, this talk will focus on the security protection schemes built into PocketPC software, and how these protections are circumvented. Using the same tricks, tools, and techniques that crackers use to bypass anti-piracy schemes, we will demonstrate first hand how these programs are cracked using a simple 'crackme' serial validation program as an example. We will start with a discussion on the hardware environment and reverse-engineering fundamentals to provide a background and foundation for the core of the talk; a step-by-step demonstration on how to crack a real program.

Seth Fogie has co-authored three security books, the latest of which (Maximum Wireless Security) has topped the best seller list for wireless security books. He is currently the VP of Airscanner, an up and coming wireless security software company. In addition, Seth also co-hosts's security section, where he both manages and writes articles and book reviews for Pearson's authors.

Hack Any Website

This session will learn how you can hack any website whatever its protection. The most basic and simple attack against a website is to change the content of one of its pages. When trying to attack a website, one first thinks to attack the web server. But attacking the client could be easier and more powerful. This is what you will see during this session. In one hour, you will understand how to take the full control of Internet Explorer 4.x and above and modify on-the-fly the content of any HTML page before it is rendered.

Internet Radio Politics: A Tale Of Betrayal And Hope

A summary of the current legal state of internet radio. How the RIAA, a group of popular commercial webcasters, and Congress conspired to betray smaller webcasters, in an attempt to eliminate the majority of stations broadcasting on the internet. We will compare the philosophies of those who see internet radio as just another mass medium to be controlled and consolidated into as few stations as possible, and those who want to maintain a large number of stations with a rich variety of programming, and how these groups are fighting to influence the public, Congress, and the media. We'll close with a look at the future of internet radio, and outline the Webcaster Alliance's strategy to break the RIAA's hold over this new medium.

Brian Hurley runs Detroit Industrial Underground, an internet radio station which plays industrial and electronica genres. DIU has been broadcating since February of 1999. The station features music by independent artists, with an emphasis on Michigan based bands. Hurley has been active in the internet radio community since DIU started brodcasting, and has participated in Castercon 2000, and spoke at Rubi-con 5 on internet radio politics. He is one of most politically active hobbyist webcasters, and has been quoted in several publications on the subject.

He is an officer in the Detroit Electronica Coalition, and an active member of the Motor City Music Foundation Advisory Board. The MCMF produces the annual Detroit Music Awards.

Ann Gabriel is President of the Webcaster Alliance, and CEO and founder of Gabriel Media, Inc. She has been producing streaming media events since 1998.

Why Anomaly Based Intrusion Detection Systems Are A Hackers Best Friend

The security market is booming. New types of tools are emerging all the time with promises of being able to protect networks better than the last generation.The newest trend is anomly based intrusion detection systems.These systems claim the ability to detect new types of attacks before comprable signature based systems while being able to scale to higher network speeds. Are these claims true? Will these systems be the silver bullet to protectthe clueless? Are these tools any better than the other script kiddie prevention tools? This talk will answer these questions and more.

New and improved Icer 3.1.4 is smarter and faster than the previous versions. He's more l33t than ever and his skill at breaking security tools is best. Not to mention he knows 20 ways to make the ladies call him Big Daddy.

Icer exists in a world beyond your world. What we only fantasize, he does. He lives in Atlanta, where nothing is beyond him, including ripping quotes from bad movies and consuming large amounts of guinness at the Highlander. Icer is still amazed Martin Sargent answers emails.

Credit Card Networks 101: What They Are, and How to Secure Them

Credit card networks have grown into a viable and necessary asset in large transaction based businesses. Are these networks protected? Are there formal security measures to protect these packets from external, and internal threats? Most network administrators, controllers (CFO) and CIO's are not even aware of credit card's flow or existence on a network. Further some over protect their switched network, disabling these systems from working correctly. One needs to have knowledge of these networks, know the possible exploits, and how to secure them.

Robert Imhoff S4SE*: has worked in the computer security industry for over 4 years, focusing his more recent in the credit card technology sector. He has worked with large credit card networks ranging from Casino and Hotel to Internet based e-commerce world wide. He currently works for a major eTransaction solutions provider servicing these type of major clients on a day to day bases. He is currently working on a "global solutions" project to help streamline the processes of integrating these networks security in cooperate LAN/MAN/WAN topology's.


Introducing nmrcOS

nmrcOS provides a secure environment for the modern hacker-type to call home, which would help protect the privacy and security of the users of the system. In addition, it provides a portable working environment for the hacker on the go— easy loading on simple hardware, no-nonsense command-line for uber control, yet usable by most people out of the box.

Discussion will focus on the history of the project and current design choices. Details on how to develop for the system will also be presented. Presentation includes demonstration of installation and configuration.

Inertia can neither confirm nor deny that he/she is a member of the Nomad Mobile Research Centre, an international group of hackers that explore technology. Further, it cannot be determined if he/she is co-author of ncrypt, a secure encryption tool. It is unknown whether Inertia's latest project involves the development of nmrcOS, the official NMRC distribution of Linux.

Stack Black Ops:  New Concepts for Network Manipulation

What can your network do? You might be surprised. Layer by layer, this talk will examine previously undocumented and unrealized potential within modern data networks. We will discuss aspects of the newest versions of scanrand, a very high speed port scanner, and the rest of the Paketto Keiretsu. Interesting new techniques will also discussed, including:

  • Bandwidth Brokering - a technique that allows market-based load balancing across administrative boundries using existing TCP protocols
  • DHCP-less Bootstrapping - a sub-optimal but effective strategy for bootstrapping network access for hosts that cannot directly acquire a DHCP lease
  • State Reconstruction - a design model that allows stateless network scanners (such as scanrand) to acquire deep knowledge about scanned hosts
  • Multihomed Node Detection - a simple set of techniques that expose firewalled hosts with alternate paths to an unfirewalled network link.
  • Generic ActiveX Encapsulation - a step-by-step methodology for safely launching arbitrary win32 tools (such as putty or a Cygwin OpenSSH environment) from a web page

We will also be discussing significant advances in data visualization, made necessary by the sometimes daunting amount of raw information these sorts of tools can expose one to.

Dan Kaminsky, also known as Effugas, is a Senior Security Consultant for Avaya's Enterprise Security Practice, where he works on large-scale security infrastructure. Dan's experience includes two years at Cisco Systems designing security infrastructure for large-scale network monitoring systems, and he is best known for his work on the ultra-fast port scanner scanrand, part of the "Paketto Keiretsu", a collection of tools that use new and unusual strategies for manipulating TCP/IP networks.

Dan is based in Silicon Valley.

Tony (aka Xam) Kapela
Fashonably Late - What Your Networks RTT Says About Itself

In this session, we will explore network fingerprinting through the use of high-frequency active probes to determine the network's delay. We will also discuss how signal analysis techniques on those delay measurements can be employed to characterize a network's performance and configuration. Using examples from a real-world enterprise network, various layer-1 and layer-2 features will be exposed including: a router or switch's queuing behavior, evidence of unrelated cross-traffic, and the presence of a configured monitoring or "span" port, perhaps indicating the presence of an eavesdropper.

Tony Kapela still has too much time on his hands. He's spoken at the past two Defcons with Adam Shand and Bruce Potter on various wireless network topics, and was a pannelist at Rubicon 5.

Currently He is spending time volunteering in a network research lab at the University Of Wisconsin, Madison, and does freelance network engineering & RF system design.

For balance, Tony often climbs radio towers (it's not really work, is it?) and hones his skills at bass guitar and percussion performance.

Information Leakage --- You posted what?!

If information is power, they why are so many organizations willing to give away this power? Are they are not aware of the risk to their network by posting network diagrams on the Internet? Or to staff, by posting the CEO’s home addresses, wife and kids names on their website? Or to the organizations financial wellbeing by leave their financial transactions zipped on their company ftp server?

The focus of this presentation will show the ways organizations release information both intentionally and non-intentionally.

Joe Klein, CISSP has been involved in IT security since 1988. During that time he has performed many Competitive Intelligence studies and consulted on protecting against Information Leakage. Over the years he has been a Security Engineer and Chief Security Officer in various company’s in the southeast US. He currently is Sr. Security Consultant at Avaya Corporation.

HavenCo: What Really Happened

HavenCo, an attempt at creating an offshore data haven, was launched in 2000 by a small team of cypherpunks and pro-liberty idealists.

During 2002, the Sealand Government decided they were uncomfortable with their legal and PR exposure due to HavenCo, particularly in the post-DMCA and post-911 world, and regulated, then took over the remains of the business, forcing the remaining founders out. While HavenCo continues to serve a small number of customers, it no longer is a data haven, and has exposed the ultimate flaw in relying on a single physical location in one's quest for privacy.

Ryan Lackey was with HavenCo from inception until late 2002, and will tell exactly what happened (not the PR-friendly whitewashed version) from day one until the end, what lessons were learned, and how similar goals can be achieved in the future by motivated individuals and groups.

Watching the Watchers: Target Exploitation via Public Search Engines

In today's world of all-knowing, all-seeing search engines, it should come as no surprise that very sensitive information lies in the deep recesses of big search engines' data banks.

What may come as a surprise, however, is just how much of a search engine's collected data exposes security flaws and vulnerabilities about the crawled sites. In some cases, even after a security hole is fixed, a search engine may cache data about that vulnerability, providing information about other avenues of attack. This process of "watching the watchers" is not theoretical. It happens, and it happens daily.

This session demonstrates the technique of crawling one of the most popular search engines for security vulnerabilities on one or many targets simultaneously.

Sample information will be extracted about various friendly targets without sending any data or packets to the intended targets, leaving those targets completely unawares.

A database of hundreds of vulnerabilities (and growing) will be uncovered and presented to the participants, as well as an automated tool which can be used to scan search engines for vulnerabilities on participant's hosts and networks.

A little-known research page has been started with working examples of this technique applied to one popular public search engine. See for details.

This presentation (especially when presented in conjunction with a live internet feed) is not only informative and eye-opening, but both refreshingly fun and amazing to watch. Most participants will have a great deal of familiarity with the search engines presented and will be delighted (and rightfully concerned) to see them operating in a manner they were not designed for. Solutions for remedying and controlling this amusing (yet very serious) vulnerability will also be discussed.

Johnny Long has actively explored both sides of the computer security fence, but since the grass was greener with a paycheck as a security professional, he now opts to spend his time as one of the good guys.

Johnny did not develop his skills within the hallowed halls of higher learning but rather by spending way too many late nights huddled in front of his computer, developing his anti-social tendencies.

Although Johnny finds it ironic that he is often asked to speak before large groups of intelligent, educated and highly technical security people, he has found his niche within the world of intelligent and highly technical security people.

Mr Long has previously presented at SANS and other computer security conferences nationwide. In addition, Mr Long has presented before several government entities including NSA, NASA, FBI, DOJ, AFOSI, AFIWC, DOE, US, canadian and Australian DOD, DCITP, DCFL, and the US ARMY. During his career as an attack and penetration specialist, Mr Long has performed active network and physical security assessments for hundreds of government and commercial clients."

He received a PhD in Electrical and Computer Engineering from Rice University, was on the Faculty of the University of Texas Medical School in Galveston, and was Chief Scientist at PentaSafe Security Technologies. He is currently Chief Scientist at White Oak Labs in Houston, Texas.



Mimicry is the ability to survive by mimicking your surroundings. In 1996 a book named Disappearing Cryptography by Peter Wayner was published and with it proof of concept code called the mimic functions that allow for encrypted data to be hidden in innocent looking text. This allows for encrypted data to be passed through networks undetected by filters looking for anything out of the ordinary. This talk will include an introduction to how the mimic functions do what they do and will also be an introduction to a tool called ircMimic that uses the mimic functions to hide data in an IRC conversation.

Mystic is a poetic coder and a self described "creative hacker".

Today's Modern Network Killing Robot

Today's Modern Network Killing Robot will give an overview on the new generation of DDOS tools. Back in the day, a couple of large pings could take down lots of machines. When those techniques stopped being effective means of taking down networks, people started writing DDOS programs. These programs required a little bit of manual work to install, but were effective at taking down large networks for a while. This generation of DDOS tools were made famous in the media by DDOS'ing famous websites for hours at a time. Soon people learned to control the damage done by these tools, and so a new generation of DDOS tools were born: Ones that could infect thousands of machines automatically to create large botnets, and hide their communications in order to evade detection better than their predecessors.

These botnets are now the most effective DDOS tools in popular use today. This talk will go over the more popular botnets, such as gtbot and sdbot, and talk about how they work and some ways to spot them on your network.

There will be a demonstration of an irc botnet in action.

Viki Navratilova lost on Hacker Jeopardy when she wouldn't agree that WEP is secure. After getting her B.S. in C.S., she's bounced around various corporations in the Chicago area doing computer security, 5ESS, and Unix admin stuff. She has collected clothing with company logos from all of them. Her writings on Linux and computer security have been published in web page, magazine, newspaper, and book form.

In 2001 Viki got the Chicago Tribune to publish a map of all the open wireless networks in downtown Chicago on the front page of the Business section to go along with her article on widespread unsecured wireless networks.

Adversary Characterization and Scoring Systems

Cyber adversary characterization is a topic which was conceived by the panel members along side other members of the computer security and intelligence communities in an attempt to provide an accurate way to build profiles of cyber adversaries, much like the way in which criminal psychologists profile more traditional criminals.

The characterization metrics conceived attempt provide a characterization of both theoretical adversaries, classing them based on statistics harvested from the wild and an accurate way of characterizing an adversary at an incident response level by studying the methodologies used during the attack.

The panel will begin with an introduction to the topic, followed by in depth discussion regarding the various characterization metrics and their applications; toward the end, we will be taking questions from the floor.

Bluetooth – The Future of Wardriving

By some estimates, there are more Bluetooth radios deployed than 802.11 radios. However, Bluetooth as largely been ignored by the security community. Over the next several years, this will change dramatically as Bluetooth security tools catch up with 802.11 security tools. Bluetooth devices tend to be always-on machines that generally contain and transmit highly personalized information. Due to limitations of the platforms and interfaces that utilize Bluetooth, many developers chose to avoid implementing security mechanisms. This combination of private information and lowered security makes Bluetooth a likely candidate for attacks targeted at an individual… or simply an interesting protocol to keep voyeurs happy.

This talk will cover the basics of the Bluetooth protocol and its security mechanisms. I will discuss attacks that may be carried out against Bluetooth enabled PANs. I will compare Bluetooth and 802.11, especially from a discovery and interception point of view. Finally, I will present The Shmoo Group’s new Bluetooth wardriving utility.

Bruce Potter has a broad information security background. From application security assessments to low-level smartcard analysis to wireless network deployments, Bruce has worked in both the open- and closed-source communities. Trained in computer science at the University of Alaska Fairbanks, Bruce now serves as a Senior Security Consultant for Cigital, Inc. in Dulles VA.

Technical Security Countermeasures: The Real Story Behind Sweeping for Eavesdropping Devices

As a corporate security advisor, former investigator, and TSCM technician, we will dispel the myths behing bugging and wiretapping. We will separate what tappers can and can not do (everything you see in the movies is not always true!!). What companies can do that will realistically protect themselves from eavesdropper and thereby help to protect their network, proprietary information, and intellectual property. We will explain and demonstrate the sophisticated electronic tools used by a professional sweep team, and describe what happens during the sweep process. We will demonstrate how phones are tapped in homes(analog phones), small businesses (KSU telephones systems), and larger companies (PBX systems). We will show how corporate spies attempt to infiltrate company telephone systems and ultimately compromise your network infra-structure. We show how anything purchased to detect eavesdropping from a "spy shop" will only waste your money and give you a false sense of security. We lay out the planning and execution of a successful sweep, and explain how to protect your company from threats in the future.

Hacking Web Apps

WARNING: The vulnerabilities you are about to see are real. Only the names have been changed to protect the vulnerable. Viewer discretion is advised.

Is your web application secure? Many have found out the hard way: encryption and firewalls are not enough.

Since 1996 the instructor has performed security assessments against web-based applications for Fortune 500 companies. The applications audited included consumer banking (US, Europe, and Asia), business banking, credit unions, conference & travel reservation systems, credit card applications & account access, 401K account access, stock broker transactions, and consumer telephone account access.

What were the real-world vulnerabilities encountered? Come see for yourself as this fast paced course re-enacts these hacks. See what the weaknesses were and how they were exploited.

If Fortune 500 companies made these mistakes, chances are good that they are not alone. The lessons learned will apply to web portals, e-commerce (B2B or B2C), online banking, shopping, subscription-based services, or any web-enable application.

  • Watch how attackers manipulate HTTP and HTML to locate web app vulnerabilities
  • See the latest hacker tools and techniques for web apps
  • Demo: Real-world web app weaknesses and exploits will be demonstrated live
  • The vulnerabilities demonstrated will be based on real vulnerabilities seen by the instructor while auditing customers &Mac246; only the names have been changed to protect the vulnerable.
  • This presentation offers valuable insight into some subtle but serious dangers for online applications

HTTP IDS Evasions Revisited

HTTP IDS evasions have been prevalent ever since the release of RFP's whisker. But what's been happening since? This presentation addresses the advancement in HTTP IDS evasions since whisker. Some of the specific topics covered will be:

  • The evolution of protocol-based IDS and signature-based IDS in regards to HTTP evasions. What's the same and what's different?
  • Latest and greatest obfuscations in URL Encoding (what the IDS vendors don't know). We'll go into the various types of URL encodings, how the different types of Unicode encoding really work, and new encoding types and combinations that confuse IDS HTTP decoders.
  • Evasions using HTTP/1.1 protocol characteristics, in the spirit of Bob Graham's Sidestep program.

The following source code will be released to demonstrate and automate the various URL encoding methods and HTTP/1.1 protocol evasions tactics:

  • Source code for automatically generating URL IDS evasions using the tactics discussed in the presentation.
  • Source code for generating Unicode codepoint values on target IIS machines for further fun with URL obfuscation and evasion.
  • Source code that profiles web servers for what types of evasions do and do not work against them -- hopefully this can be released.

Daniel Roelker is a security researcher and software developer for Sourcefire, Inc in Columbia, MD. His most recent projects include a new HTTP protocol decoder for the Snort IDS (soon to be released) and his work on the Snort 2.0 high-speed detection engine with fellow developer Marc Norton. Previous to working at Sourcefire, Dan Roelker was a lead developer on the Dragon Network IDS at Enterasys Networks where he worked on application protocol decoders, high-speed packet capturing technology, event correlation (with Randy Taylor), and revamping the Dragon detection engine. Dan has also had fun working at the Johns Hopkins Applied Physics Lab in Information Operations for the DoD. He could tell you about it but then he'd have to kill you... His current security research is located at, which is currently under construction but will be done by Defcon.

Punishing Collaborators Redux: CAPPS II, Passenger Profiling, and the Boycott of Delta Air Lines

Just when you thought Total Information Awareness was dead, The Department of Homeland Security rolled out plans in February of this year to introduce an Orwellian airport passenger profiling system called CAPPS II. The plan originally called for running checks on credit, banking, and criminal records every time a citizen flew on a commercial aircraft. Bill Scannell didn't feel like being asked 'papers, please' every time he traveled, so he targeted the only airline participating in the testing of CAPPS II: Delta Airlines. The resulting Delta boycott and millions of dollars in negative publicity caused Homeland Security to pull the plug on the program pending a privacy investigation, and for Congress to withhold all 2004 funding.

Bill Scannell has been active in the cypherpunk and privacy community for a number of years. A former US military intelligence officer turned foreign correspondent turned publicist, Scannell launched some of the most important privacy projects of the last few years, including HavenCo and MojoNation. Together with Paul Holman, he launched a successful boycott of Adobe Systems in 2001 in response to the arrest of Dmitry Slylarov at DefCon that year. His latest successful project is

The Internet's Private Cops: Defending Your Rights Against Corporate Vigilantes

It is not only governments that are engaged in surveillance of Internet activity. Increasingly, private actors, including corporations asserting intellectual property interests, are being given the power to police the network and demand user identities, in the name of enforcing their private interests. Even when the law does not give them the authority, some have been overzealous in sending legal threats claiming such rights. This presentation will examine the legal claims (such as DMCA, copyright, trespass) frequently raised by private parties, your rights in response, and ways to protect yourselves from these threats, including via the Chilling Effects website.

Wendy Seltzer is a Staff Attorney with the Electronic Frontier Foundation, specializing in intellectual property and free speech issues. As a Fellow with Harvard Law School's Berkman Center for Internet & Society, she founded and leads the Chilling Effects Clearinghouse, helping Internet users to understand their rights in response to cease-and-desist threats. Prior to joining EFF, Wendy taught Internet Law as an Adjunct Professor at St. John's University School of Law and practiced intellectual property and technology litigation with Kramer Levin Naftalis & Frankel in New York. Wendy speaks frequently on copyright, trademark, open source, and the public interest online. She has an A.B. from Harvard College and a J.D. from Harvard Law School, and occasionally takes a break from legal code to program (Perl).

With over 32,000 Frontpage enabled webservers currently on the Internet, it's easy to take it for granted. However, Microsoft Frontpage is one of the least documented and most mis-understood web authoring systems available.

In this presentation we will seek to close that gap, and expose the inner working of the Frontpage and Frontpage Server Extensions protocol. We'll show the hidden flags and undocumented options within the session data, many of which are unavailable even to Microsoft Frontpage users!

Plus we will debut new open source tools geared directly toward taking advantage of the Frontpage systems, including a Perl-Gtk Frontpage vulnerability scanner.

Our presentation will cover the following areas:

  • Frontpage: An Initial Perspective
    "Breaking down the overall system, providing an overall process view.
  • Frontpage: Decoding the System
    "Explaining the authentication system, the protocol spec, command sequence, and undocumented options
  • Frontpage:Knocking on the door
    "Debut custom tools built to specifically manipulate the authentication system and provide an open source Frontpage vulnerability scanner.
  • Frontpage: What to do when your there
    "Provide a basic understanding of Microsoft's Active Server Pages Visual Basic language, and provide example hacker tools developed in ASP.
  • Frontpage: Holding down the fort
    "Give those supporting frontpage the much needed information to help better secure their enterprise.

Increasing The Security Of Your Election By Fixing It

In response to the problems that plagued the last United States presidential election, many communities plan to replace existing paper ballot machines with electronic voting systems. Unfortunately, the new systems open up a Pandora's box of security issues that traditional paper ballots do not face. It is difficult to understand the issues because there is a serious lack of data describing the real world performance of these systems. This problem is compounded by the fact that the major commercial vendors' products are closed, proprietary systems protected as trade secrets. Ignorance of the unique security concerns raised by electronic voting could leave US State and Federal elections open to unprecedented levels of fraud.

This past April, a new online election system was used at the University of California at Berkeley. We present this system as a case study, which sheds much needed light on electronic voting security. We describe the workings of this system, and discuss the findings of our security analysis. Additionally, we crafted a man-in-the-middle attack that exploits a flaw inherent in the system architecture. Our talk provides a detailed technical explanation of the attack.

Finally, we discuss the implications of the case study. We will show that many of our conclusions apply to the major commercial systems, in spite of tangible differences with the case study system. We will answer questions from the audience, and offer constructive ways to address some of the concerns we raise.

This talk is suitable for attendees of all technical levels. For a thorough understanding of our man-in-the-middle attack, we suggest that you have some programming experience and familiarity with DNS and NAT.

Hacking the Invisible Network: The Risks and Vulnerabilities Associated with Wireless Hotspots

Wireless hotspots are emerging as an effective means of providing on-demand Internet access for users with 802.11x enabled devices. The networks typically exist in places frequented by business travelers, such as hotels, airports or in locations with persistent clientele such as coffee shops. The technology provides an efficient and cost effective way for companies to deliver Internet access to their customers and also offers an alternate revenue source, as many networks are “pay for play”.

Most users are enticed by the convenience of these networks, but are unaware of the security risks that they present. Companies have historically implemented security by building an impenetrable fortress around network assets. This system is flawed. It does nothing to protect the multitude of portable devices such as laptops and PDAs that are frequently used outside of this fortress. Hotspots are shared networks that broadcast traffic. By design, hotspots do not implement encryption schemes such as WEP, which provides a target rich environment for malicious attackers. Unencrypted network traffic can be intercepted and traditional remote attacks can be perpetrated on machines that are operating without protection from attack. This poses a significant risk for corporations as these devices commonly contain sensitive corporate data.

Research conducted on numerous hotspot implementations has revealed that most leave end users unnecessarily exposed to both local and remote attackers. Most networks also have weak access controls that leave business owners exposed to loss of revenue from various attack scenarios such as session hijacking, data tunneling and connection sharing.

The presentation will address the following:

  • The risks associated with using Hotspots
  • Specific attack scenarios – identifying tools and techniques that were used
  • The network design of specific hotspot implementations
  • What users can do to protect themselves

Hacker Generations: From Building the Network to Using the Network to Being the Network

It has all happened so fast.

Eleven years of Def Con define three identifiable generations of hackers. (Yes, that's an arbitrary distinction, but it's useful.)

The first generation helped build the network, the second learned how to use the network, and the third has become the network.

The management of perception in the mind of society is the battle in which we are now engaged. Online life is threaded through with deception and counter-deception, intelligence and counter-intelligence, but that's second nature to the latest generation of hackers. They understand that intuitively. They operate in small cells, manage their egos with discipline, and execute stealthy sophisticated operations with finesse.

Richard Thieme shows how boundaries have morphed, power has been redefined, and The Matrix is more than a movie. Not since Blade Runner has a film described so well the territory that must be crossed. Owning our own souls is the ultimate intention of Third Generation Hacking, the only end that justifies the means.

Thieme holds nothing back as he addresses the deeper implications of what it means to be the network. The stakes are high and the battle is worthy of our best efforts. This talk is a call to arms to accept responsibility for the life and death battle being waged for the hearts and minds of digital humanity.

The Story of EFFI. How We Started a Cyber-rights Group in Finland, Which Kicks Ass

We want to show you how just a couple of fellows can start a truly efficient cyber rights group at a regional level (state, country etc) and influence the encryption, privacy, fair use etc laws & change the public opinion. We did this in Finland in a year.

EFFI was founded in 2001 and now, in summer 2003, has some 300-400 paid members and counting. We got to the nation's main newspapers in spring 2002 and hit the radio and TV in fall 2002 and been since then regulars in the media. Our top achievement so far has been stopping EU Copyright Directive (Europe's DMCA) in Finland. We've also fundamentally changed the law on the feeedom of speech and spamming (see for details).

Next, we'll answer basic questions on how we get there. Who proposes these laws and how can even individual hackers and tech enthusiasts influence the legislative process? How did we build relationships to politicians? How did we got ourselves to TV regulars in Finland and changedthe public opinion to our support? How can we extend our regional success to European level?

Finally we want to explain why the political, moral and legal issues are inherently global and why the hacker community should support action in every corner of the world. We get into details of US and European hacker-unfriendly politics and compare different options to support our common cause: influence parliamentary and democratic process vs. act independently & anonymously hacking the software of "evil corporations". Our approach is to act with names and do everything politically correct.

Network Worms, What Is Possible

Network worms have been around for almost as long as the computer networks they need to spread via, but it only with the advent of mass internet access that they have become commonplace. This presentation will outline what network worms are, and how they differ from a ‘normal’ computer virus. but in the main concentrate on what future worms could achieve.

The presentation will look forward to what we could see in both the near, and far future giving examples of what can be developed. Web replication and other possible distribution methods will be discussed and you will learn why so few worms currently effectively achieve mass distribution.

No prior technical knowledge is required of the audience, and should be understandable by those with limited knowledge of computers, although greater knowledge will be a plus.

Jonathan Wignall is the Chair of the Data and Network Security Council a UK not for profit information security campaign group, calling for improved online security/privacy protection. He also is an experienced college lecturer with research intrests in self replicating code and network dependency attacks.

Deploying DNSSEC

Although DNSSEC is still a moving target, it has matured enough for large scale experimenting. The first part of the presentation explains the new concepts in DNSSEC and the new record types introduced. Rudimentary knowledge of DNS is required.

The second part of the presentation is a step-by-step guide using Bind to secure an existing zone. Participants who which to secure their own domain need to have the latest Bind9 snapshot and a copy of the zones they wish to secure.

The third part of the presentation will demonstrate the interaction between the Registrant and the Registrar. The Dutch SECREG system will be demonstrated for securing .nl domains at the ccTLD. The VeriSign experiment will also be shown on how to secure the generic TLD's. Time permitting, participants are invited to try and compromise the Speaker's secured zones.

Paul Wouters has been involved with Linux networking and security since he co-founded the Dutch ISP "Xtended Internet" back in 1996. His first article about network security was published in LinuxJournal in 1997 Since then, he has written mostly for the Dutch spin-off of the German "c't magazine", focussing on Linux, networking and the impact of the digital world on society. He has presented papers at SANS, OSA, CCC and HAL.

He is currently involved with the FreeS/WAN project, a Linux IPsec stack that aims to bring Opportunistic Encryption to everyone. For this feature, a secure DNS is needed, which triggered his interest in assisting the widespread use of DNSSEC. Wouters received his Bachelors degree in Education in 1993

For that, he was the target of a three-year criminal investigation, because the government held that US export restrictions for cryptographic software were violated when PGP spread all around the world following its 1991 publication as freeware. Despite the lack of funding, the lack of any paid staff, the lack of a company to stand behind it, and despite government persecution, PGP nonetheless became the most widely used email encryption software in the world. After the government dropped its case in early 1996, Zimmermann founded PGP Inc. That company was acquired by Network Associates Inc (NAI) in December 1997, where he stayed on for three years as Senior Fellow. In August 2002 PGP was acquired from NAI by a new company called PGP Corporation, where Zimmermann now serves as special advisor and consultant. Zimmermann currently is consulting for a number of companies and industry organizations on matters cryptographic, and is also a Fellow at the Stanford Law School's Center for Internet and Society.

Before founding PGP Inc, Zimmermann was a software engineer with more than 20 years of experience, specializing in cryptography and data security, data communications, and real-time embedded systems. His interest in the political side of cryptography grew out of his background in military policy issues.

He has received numerous technical and humanitarian awards for his pioneering work in cryptography. In 2001 Zimmermann was inducted into the CRN Industry Hall of Fame. In 2000 InfoWorld named him one of the Top 10 Innovators in E-business. In 1999 he received the Louis Brandeis Award from Privacy International, in 1998 a Lifetime Achievement Award from Secure Computing Magazine, and in 1996 the Norbert Wiener Award from Computer Professionals for Social Responsibility for promoting the responsible use of technology. He also received the 1995 Chrysler Award for Innovation in Design, the 1995 Pioneer Award from the Electronic Frontier Foundation, the 1996 PC Week IT Excellence Award, and the 1996 Network Computing Well-Connected Award for "Best Security Product." PGP was selected by Information Week as one of the Top 10 Most Important Products of 1994. Time Magazine also named Zimmermann one of the "Net 50", the 50 most influential people on the Internet in 1995.

In addition to the awards for versions of PGP developed before Zimmermann started a company, subsequent versions of PGP as refined by the company's engineering team continue to be recognized each year with many more industry awards.

Zimmermann received his bachelor's degree in computer science from Florida Atlantic University in 1978. He is a member of the International Association of Cryptologic Research, the Association for Computing Machinery, and the League for Programming Freedom. He is Chairman of the OpenPGP Alliance, serves on the Boards of Directors for Computer Professionals for Social Responsibility and Veridis, and is on the Advisory Boards for, Hush Communications, and Qualys.
