Identity and Disinformation: Playing Chess in Multiple Dimensions
Let's not kid ourselves: security in the 21st century is about the
management of perception, the juggling of useful illusions, and the
supervision of multiple identities while they go about their business. The
only question confronting masters of information security is, how much red
pill can you swallow?
Philosophical questions are irrelevant only if you don't want to examine the
essence of information security. Those who do are willing to open a door
leading into a hall of mirrors, free spirits willing to dance with the devil
And as the devil said (in Woody Allen's Deconstructing Harry), "Sometimes
youre up and sometimes you're down. In the end, the house always wins. It
doesn't mean you didn't have fun."
This presentation is about having fun while you secure illusory boundaries
so others can play the game, too ...
Tom Stracener - "Advanced Cross-Site Scripting Scenarios, Filter Evasion and Browser Exploits"
Richard Thieme (www.thiemeworks.com) is an
author and professional speaker focused on the deeper implications of
technology, religion, and science for twenty-first century life. He has
spoken for Def Con for ten years and Black Hat for eight as well as for
venues ranging from ShmooCon, Pump Con and ToorCon to InfraGard and AUSCERT
to the Pentagon, the FBI, Los Alamos National Laboratory and the US
Department of the Treasury. He has consulted for Network Flight Recorder,
Neohapsis, Psynapse/Center for the Advancement of Intelligent Systems,
OmniTech, and SPC (System Planning Corporation. His internet columns,
"Islands in the Clickstream," are widely read and were published by Syngress
Publishing in June 2004. Since then he has published fourteen short stories
including "The Geometry of Near," a hacker tale published by Phrack and
included in the anthology CyberTales: Live Wire. A short story collection,
More Than a Dream: Stories of Flesh and the Spirit is coming soon and he is
writing a novel, The Necessity for Invention, which includes the adventures
of Don Coyote and Pancho Sanchez, two suitably wily hackers.
In a subject matter so heavily trafficked by security vendors and researchers, the most often overlooked topic is the potential impact of cross-site scripting in a real world setting. Cross-Site Scripting in web applications is nothing new but, despite being a very well known vulnerability, the deep internals of cross-site scripting, as an attack, are still regarded as fundamentally mysterious. In this presentation, Tom Stracener, senior vulnerability research analyst for Cenzic, will cover the latest Cross-Site Scripting techniques and discuss specific examples of how attackers can bypass application input validation filters using various mutation-based injection strategies. The presentation will also provide insight into how Cross-Site Scripting attacks can be leveraged within the context of an intruder's overall plan to penetrate a web application, how such attacks can be deployed and used, and attack combinations. In doing so, he will cover a number of other major variations of Cross-Site Scripting attacks, from basic cookie theft to using redirects to exploit browser flaws, to content-spoofing type Cross-Site Scripting attacks that trick the user into undermining their own security. The goal of this talk is to give a practical tour de force of the script hacker's arsenal.

Security has become the limiting reagent in the broad adoption of web services. As a result, much emphasis has been placed on the development of various high-level security standards and protocols, but in most cases the simplest attacks, those at the application level, have been neglected.
Nish Bhalla and Sahba Kazerooni of Security Compass will explore, at a low-level, the vulnerabilities inherent to web services from an attacker's point of view. The talk covers the dependency of web services on xml, the various forms of xml-based attacks, including exploiting parsers and validators, and finally provides recommendations and countermeasures.
This talk is intended for developers and web application architects. It drills down to the details of web services implementation, while maintaining a focus on good versus bad architectural design.

Mackerel is a family of symmetric cryptovirus constructions that allows up to IND-CCA2 and INTCTXT security; they're based around the AES in CTR mode (IND-CPA) for preserving confidentiality and CMAC-AES (SUF-CMA) for preserving integrity. The optimal configuration (IND-CCA2 and INT-CTXT), "King Mackerel," employs two 256-bit symmetric keys, for encryption and authentication in the Encrypt-then-Authenticate (EtA) composition, and claims a 128-bit security level. All functions operate in the Troutman mode of information extortion (TIE), a slight variation of Young and Yung's information extortion attack . While Mackerel requires its own set of intrinsic analyses, it takes advantage of the analytical scrutiny of the AES; as such, the security of Mackerel reduces to that of the AES. Mackerel is based on original research conducted by Troutman, in *. Mackerel is in the final stages of preliminary cryptanalysis, of which will support Mackerel in a standalone paper, set to appear in Spring '07, along with a complementary protocol for ensuring fairness via game theory.
Advantages over Young and Yung's attack:
The original information extortion attack in  relies on asymmetric cryptography (i.e., RSA) and an RNG to produce symmetric keys for encryption, once the cryptovirus has reached the host. Because of this, the adversary hasn't a priori knowledge of the keys, and requires that the cryptovirus encrypt them with RSA, before instructing the victim to send them; this preserves the confidentiality of the symmetric keys, which the adversary uses as leverage in the attack. The RNG proves to be the bottleneck of that attack; in Mackerel, the two symmetric keys for encryption and authentication are generated beforehand, thus removing the necessity for an RNG. In turn, this also removes the necessity for RSA, since the adversary now has a priori knowledge of the keys. By removing the RNG alone, the attack's speed is doubled. Although the keys now exist in plaintext form, within the cryptovirus, the idea is that methodologies exist (i.e., malware) for getting the cryptovirus to the host fast enough for the cryptovirus to execute. Preliminary tests have largely supported this notion.

What do we, as customers or researcher, need to know about testing methodologies for IDSs ? Are the currently "standard" industry test methodologies standard enough? And, more to the point - do they actually MEAN anything? How can we make sense (or disperse the FUD) in the cloud of statistics that vendors regularly use for concealing their flaws? And should you be tasked to design an evaluation testbed for intrusion detectors in our environment, how should we deal with the various performance indexes of IDS systems?
