Sometimes even the top dudes need a refresher course. Remedial Heap Overflows is not so much a lesson to the lame, but a refresher for the leet. One day the speaker was approached (in a subway, of course) by a top-notch dude (who has his own posse) and asked how they work. Clearly not even the best of the best always know everything. atlas, a disciple of the illustrious Skodo, has a history in programming, systems support, telec..
RDS-TMC is a standard based on RDS (Radio Data System) for communicating over FM radio Traffic Information for Satellite Navigation Systems. All modern in-car Satellite Navigation systems sold in Europe use RDS-TMC to receive broadcasts containing up to date information about traffic conditions such as queues and accidents and provide detours in case they affect the plotted course. The system is increasingly being used around Europe a....
If you're responsible for the burglar alarm at your facility, do you understand how it's being monitored by the "Data Monitoring Group" flunkees? Are all those alarm conditions real? The Completion Backward Principle covers issues arising from Internet-enabled monitoring of burglar alarm systems, and possible mitigations. Spot The Fed will most assuredly be played at this talk. For the past seventeen years, geoffrey has been a Fac..
The recent case of Julie Amero has cast a bright spotlight on the difference in understanding between the worlds of technology and the law. We will examine adoption of technology within the legal profession, trial court decisions, as well as legislative and appellate decisions which may be inconsistent with generally accepted security measures. John Benson is the co-chair of the Kansas City Metropolitan Bar Association Computer Law and..
The presentation details the process whereby journalists select, discard, research and ultimately publish security related articles. It outlines the credibility necessary for security researchers to be taken seriously in the presentation of their findings and examines the "blowback" that criminal and kiddie hackers have on the security industry from a journalists perspective. This talk also looks at the current practices of legitimate ....
Intrusion Analysis has been primarily reserved for network junkies and bit biters. However, due to the advances in network systems automation we now have time to pay more attention to subtle observations left by attackers at the scene of the incident. Century old sciences have enabled criminal investigators the ability attribute attacks to specific individuals or groups. Sean M. Bodmer is an active developer and deployer of intrusion ..
Last semester I taught a new course in "Ethical Hacking and Network Defense" at City College San Francisco. I had legal, ethical, and practical concerns about this class, so I took several precautions to prevent the students from one another, and others from them. The course was a success--it was full and popular, and there were no security problems (at least none that I found out about). We have built hacking into our Computer Netwo..
I will show how entropy, a measure of information content defined by Shannon in 1948, can provide useful ways of organizing and analyzing log data. In particular, we use entropy and mutual information heuristics to group syslog records and packet captures in such a way as to bring out anomalies and summarize the overall structure in each particular data set. I will show a modification of Ethereal that is based on these heuristics,....
Being in the know" is key to supporting or violating a security infrastructure.

This talk will focus on modern radio systems and the challenges of listening to them. We will provide information on several utilities and resources t....
Cross Site Scripting has received much attention over the last several years, although some of its more ominous implications have not received much attention. Anti-DNS pinning is a relatively new threat that, while not well understood by most security professionals, is far from theoretical. This presentation will focus on a live demonstration of anti-DNS pinning techniques. A victim web browser will be used to execute arbitrary, interactive....
Have you tried to firewall a machine from itself? Have you ever tried to protect a machine with a multi-personality disorder? These questions are brought to us by the wonderful technology of virtualization. Though the technology is clearly sexy, security has clearly been an afterthought. While every product claims isolation, it seems that's only when you don't have an attacker involved. Despite what the press releases say, it's not ..
Social engineering has traditionally been more of an art than a science, we try different things, and if they work, we continue to use them over and over again. Some of the best social engineers have developed excellent technique even without understanding why what they're doing works. Mike & Anton are skilled communicators trained in NLP, hypnosis, FACS and other sciences of influence, and will present (and demonstrate) some of the cutting....
This presentation reviews the important prosecutions, precedents and legal opinions of the last year that affect internet and computer security.

Additionally, we look at topics such as: email retention and discovery; active response; use of CFAA as non-competition methods; identity theft and notifi....
Satellite imagery was once restricted to organizations like CTU, but now it is freely available to us all via powerful free online tools and commercial services. In this talk we will look at commercial collection platforms and capabilities, orbital mechanics and a variety of imagery analysis techniques. We will analyze examples from interesting places around the world and explore issues surrounding the future of satellite surveillance. ..
The core of the security problem is that most software contains latent bugs, and many of these bug can be exploited by attackers to cause the software to do something undesirable to the victim's computer. To block this threat, one can either use only perfect software (of which there is a shortage :) or use a security system to control what software may and may not do. The problem is that such systems are historically very difficult to use....
Careers in information security are often difficult to navigate, with the industry changing more and more radically every year. We're going to talk about the important skills, traits and knowledge that a security pro needs, not just the usual stuff (like "go get a CISSP"), we're going to come from the perspective of two people who spend much of their time talking to hiring managers and companies looking for security stars, as well as talkin....
Ever wanted to hijack a connection between machines on a LAN, deny service between a host you're attacking and a log server or intrusion detection system, or maybe wanted to sniff traffic on a switched network? Now you can! Er, wait... You already could with the ARP attacks we all know and love. While these network attacks are quite effective, they do have their weaknesses, as well as security controls to help prevent them. In this ....

Security researchers around the world have been SLAPPed (strategic lawsuits against public participation) across the face by vulnerable software vendors. Bogus legal threats intended to intimidate and prevent public exposure of vulnerabilities are becoming increasingly common. If the software industry succeeds at silencing these researchers the public, governments, global industries, and end user customers are ill served and increasingly....
What would you do if you had a massive collection of malware? What secrets could you uncover? This rapid fire presentation seeks to reveal some of these secrets based on the analysis of Offensive Computing's large malware collection. (Over 100,000 samples) What are malware author's commonly using to pack their binaries? What are the rarest packers, and could this indicated a targeted attack? How do Anti-Virus companies generally perform on ....
Runtime code coverage analysis is feasible and useful when application source code is not available. An evolutionary test tool receiving such statistics can use that information as fitness for pools of sessions to actively learn the interface protocol. We call this activity grey-box fuzzing. We intend to show that, when applicable, grey-box fuzzing is more effective at finding bugs than RFC compliant or capture-replay mutation black-box ....
Firstly, I will be covering the basics of SCADA networks and give a general overview of the SCADA protocols namely Modbus, DNP3, ICCP and IEC standards. North America mainly uses Modbus, DNP3 and to an extent ICCP, the European countries use the IEC standards. After the basics I will be getting into the finer details of the protocols as to what function code, internal indication flags does what and how that can be used to attack or take dow....

Today there is a lot of hype around some new proof-of-concept technology or around politically motivated trojans, etc. This talk will deliver a reality check, give an idea what kind of malware the McAfee Research organisation is actually seeing to be used in the real world and show how the different trojans work, what the impact is. The material used are internal statistics of the various threats sent to or discovered by us, some more detai....
Ever wonder just what rules law enforcement must follow? When do the police have to read you the Miranda Warnings? Who is subject to a Stop and Frisk? When does Double Jeopardy apply. What does a cop actually have to know before they can legally stop you? What is the effect of an Invalid arrest? Just when can the SWAT team kick your door without knocking first? When must an officer have a search warrant? During the "Ask the Crimi..
I will talk about the evolution and differences of the hacking communities around the world. Why and how this affects the hackers being taken to the corporate life, motivations, or just why is it better to stay totally underground. How companies attract and manage hackers, and how the scare them away. Computers are cool now, like the tshirt says, and small kids already know what ip addresses are, how to use netstat, etc. Is security gonna b....
Kernel vulnerabilities are often deemed unexploitable or at least unlikely to be exploited reliably. Although it's true that kernel-mode exploitation often presents some new challenges for exploit developers, it still all boils down to "creative debugging" and knowledge about the target in question. This talk intends to demystify kernel-mode exploitation by demonstrating the analysis and reliable exploitation of three different kernel....
There is a pervasive dream about a free Internet which is robust, fully decentralized yet efficient, and which ensures privacy for all users. For seven years, the Freenet project has been the most visible embodiment of this vision. This talk will show that the recent 0.7 release of Freenet -- marketed to solve most of the problems -- entirely fails to deliver. Freenet 0.7 promises efficient routing in restricted-ro....
