Jeff Moss introduces the Keynote and welcomes everyone tthe Amsterdam 2007 conference!
Roger will provide an overview of the work of CPNI in reducing vulnerability in information systems that form part of the UK. He will then challenge the community on a number of issues, including the development of the malicious market place, and the role security researchers in addressing vulnerabilities as used by a range of threat actors.
Until 31 January 2007 Roger Cumming was Director of the National Infrastructure Security Co-ordination Centre (NISCC), the UK centre responsible for minimising the impact of electronic attack on the UK critical national infrastructure. Since 1 February Roger has been Head of Advice Delivery and Knowledge Development at the UK Centre for the Protection of National Infrastructure (CPNI). CPNI provides protective security advice on information security as well as physical and personnel security treduce the vulnerability of the UK's national infrastructure tterrorism and other threats. -

"Adam Laurie is Chief Security Officer and a Director of The Bunker Secure Hosting Ltd. He started in the computer industry in the late Seventies, working as a computer programmer on PDP-8 and other mini computers, and then on various Unix, Dos and CP/M based micrcomputers as they emerged in the Eighties. He quickly became interested in the underlying network and data protocols, and moved his attention tthose areas and away from programming, starting a data conversion company which rapidly grew tbecome Europe's largest specialist in that field (A.L. downloading Services).
During this period, he successfully disproved the industry lie that music CDs could not be read by computers, and, with help from his brother Ben, wrote the world's first CD ripper, 'CDGRAB'. At this point, he and Ben became interested in the newly emerging concept of 'The Internet', and were involved in various early open source projects, the most well known of which is probably their own-'Apache-SSL'-which went on tbecome the de-factstandard secure web server.
Since the late Nineties they have focused their attention on security, and have been the authors of various papers exposing flaws in Internet services and/or software, as well as pioneering the concept of re-using military data centres (housed in underground nuclear bunkers - http://www.thebunker.net) as secure hosting facilities.
Adam has been a senior member of staff at DEFCON since 1997, and alsacted as a member of staff during the early years of the Black Hat Briefings. More recently he has become interested in mobile device security, and was responsible for discovering many major Bluetooth security issues, and has alsspoken on other wireless topics such as InfraRed and Magnetic Stripes. His current interest, RFID, has spawned another Open Source project, RFIDIOt, which is alsbringing several security issues tthe fore. More detail can be found here: http://rfidiot.org" -

"Heap exploitation is getting harder. The heap protection features in the latest versions of Windows have been effective at stopping the basic exploitation techniques. In most cases bypassing the protection requires a great degree of control over the allocation patterns of the vulnerable application.
This presentation introduces a new technique for precise manipulation of the browser heap layout using specific sequences of JavaScript allocations. This allows an attacker tset up the heap in any desired state and exploit difficult heap corruption vulnerabilities with great reliability and precision.
This talk will begin with an overview of the current state of browser heap exploitation and the unreliability of many heap exploits. It will continue with a discussion of Internet Explorer heap internals and the techniques for JavaScript heap manipulation. I will present a JavaScript heap exploitation library that exposes an abstract heap manipulation API. Its use will be demonstrated by exploit code for twcomplex heap corruption vulnerabilities.
The talk will focus on Internet Explorer exploitation, but the general technique presented is applicable tother browsers as well. "

"The last years have seen the growth of botnets and its transformation inta highly profitable business. Most of the botnets seen until now have used the same basic concepts. This presentation intends tshow what are the major challenges faced by botnet authors and what they might try in the future tsolve them. The presentation will pass through some interesting solutions for botnet design challenges. A layered and extensible approach for Bots will be presented, showing that solutions from exploit construction (like metasploit), P2P networks (Gnutella and Skype), authentication (digital signatures) and covert channels research fields can be used tmake botnets more reliable, extensible and hard tput down."

"The Achilles' heel of network IDSes lies in the large number of false positives (i.e., false attacks) that occur: practitioners as well as researchers observe that it is common for a NIDS traise thousands of mostly false alerts per day. False positives are a universal problem as they affect both signature-based and anomaly-based IDSs. Finally, attackers can overload IT personnel by forging ad-hoc packets tproduce false alerts, thereby lowering the defences of the IT infrastructure. Our thesis is that one of the main reasons why NIDSs show a high false positive rate is that they dnot correlate input with output traffic: by observing the output determined by the alert-raising input traffic, one is capable of reducing the number of false positives in an effective manner. Tdemonstrate this, we have developed APHRODITE (Architecture for false Positives Reduction): an innovative architecture for reducing the false positive rate of any NIDS (be it signature-based or anomaly-based). APHRODITE consists of an Output Anomaly Detector (OAD) and a correlation engine; in addition, APHRODITE assumes the presence of a NIDS on the input of the system. For the OAD we developed POSEIDON (Payl Over Som for Intrusion DetectiON): a two-tier network intrusion detection architecture.
Benchmarks performed on POSEIDON and APHRODITE with DARPA 1999 dataset and with traffic dumped from a real-world public network show the effectiveness of the twsystems. APHRODITE is able treduce the rate of false alarms from 50% t100% (improving accuracy) without reducing the NIDS ability tdetect attacks (completeness)."

"Long gone are the days of widespread internet attacks. What's more popular now are more directed or targeted attacks using a variety of different methods. Since most of these attacks will be a single shot styled attack attackers will often look for anyway tincrease the likelihood of success.
This is where data seepage comes in. Unbeknownst ta lot of mobile professional's laptops, pdas, even cell phones can be literally bleeding information about a company's internal network. This can be due tapplications like email clients that are set tstart up and automatically search for its mail server, windows may be attempting tremap network drives, an application could be checking for updates.
All this information can be used by an attacker tmake attacks more accurate with a higher likelihood of success. Don't laugh and dismiss this as a trivial problem with nimpact. Through demonstrations and packet caps we will show how this problem can be the weak link in your security chain. " -
"Kernel vulnerabilities are often deemed unexploitable or at least unlikely tbe exploited reliably. Although it's true that kernel-mode exploitation often presents some new challenges for exploit developers, it still all boils down t""creative debugging"" and knowledge about the target in question.
This talk intends tdemystify kernel-mode exploitation by demonstrating the analysis and reliable exploitation of three different kernel vulnerabilities without public exploits. From a defenders point of view this could hopefully serve as an eye-opener, as it demonstrates the ineffectiveness of HIDS, NX, ASLR and other protective measures when the kernel itself is being exploited.
The entire process will be discussed, including how the vulnerabilities were found, how they were analyzed tdetermine if and how they can be reliably exploited and of course the exploits will be demonstrated in practice. -
"ScarabMon is a new tool and framework for simplifying web application pentests. It makes the process of finding many common webapp flaws much easier. The user simply navigates the target site while using the WebScarab proxy and ScarabMon constantly updates the user with information on discovered flaws.
ScarabMon is written in Python and all code and modules will be released at the conference.
ScarabMon is alseasily extensible, with useful checks often only requiring 5-10 lines of Python code.
I wrote ScarabMon because I couldn't find anything like it.
Historically the standard web proxies have been @Stake's WebProxy (which is totally unavailable anymore as Symantec killed it after the acquisition), SpikeProxy and WebScarab. Those have have recently been joined by twother apps, WebScarab-NG and Pantera.
The latter are not ready for serious usage yet. Pantera development seems thave stalled and WebScarab-NG is missing major features, though it shows the most promise. The latest date on any of the SPIKEProxy files is from 2003.
Sbasically everyone uses WebScarab for web application pen tests.
WebScarab is obnoxious tprogram for, as you have twrite dozens of lines of Java code (BeanShell) for the simplest tasks. BeanShell is alsoften unstable.
ScarabMon is currently designed twork with WebScarab, but could be ported twork with any of the above should the need arise. Instead of acting as a proxy, it just monitors the output of the proxy and opportunistically performs tests. Some tests are things people have seen before in other tools (like finding directories that support PUT) and others aren't anything I've seen in any other tool such as finding values that were set as cookies over SSL that later wind up as a query string parameter.
The best thing is that you get all of this for free. You don't have tchange *anything* about your current testing methodology. You just run ScarabMon in the background and it sees the servers and files you're accessing and generates findings. -
"Classical debuggers make use of an interface provided by the operating system in order taccess the memory of programs while they execute. As this model is dominating in the industry and the community, we show that our novel embedded architecture is more adapted when debuggee systems are hostile and protected at the operating system level.
This alternative modelization is alsmore performant as the debugger executes from inside the debuggee program and can read the memory of the host process directly. We give detailed information about how tkeep memory unintrusiveness using a new technique called allocation proxying.
We reveal how we developed the organization of our multi- architecture framework and its multiple modules sthat they allow for graph-based binary code analysis, compositional Fingerprinting, program instrumentation, real-time tracing, multithread debugging and general hooking of systems. Finally we reveal the re?ective essence of our framework : our analyzers are made aware of their own internal structures using concepts of aspect oriented programming, embedded in a weakly typed language dedicated treverse engineering.

"When dealing with Windows exploits, an issue that often emerge is their cross-platform reliability, meaning they often work against either some given service packs of the OS, or some localization of the OS. It is quite rare tfind exploits that will work on a very wide range of Windows installs.
While multiplying the number of targets in an exploit is often the solution found in the wild, it seems that nobody has yet disclosed a solution tfingerprint a Windows language, or discuss about cross languages and service packs return addresses (though cross SP only is now fairly well mastered).
Immunity, Inc. had twork on this issue for CANVAS, in order tbuild more reliable exploits, and this paper intend texplain some of the solutions that were found tthese issues.

"Fuzzing is a software testing technique that consists in finding implementation bugs. Fuzzing Wi-Fi drivers is becoming more and more attractive as any exploitable security bug will enable the attacker trun arbitrary code with ring0 privileges (within victim's radicoverage).
This presentation will describe all the processes involved in the design from scratch of a fully-featured Wi-Fi fuzzer. It will pinpoint all issues and constraints when fuzzing 802.11 stacks (scanning, bugs identification, replaying bugs, analyzing kernel crashes...).
Then some features will be focused on, in order tunderstand which kind of implementation bugs may be discovered and which vulnerabilities we discovered thanks tthis tool (CVE-2006-6059, CVE-2006-6125).
Finally, a real-world example will be fully explained: how we found the first (publicly known) madwifi stack-based overflow thanks tour Wi-Fi fuzzer (CVE-2006-6332)."

"The SMTP protocol, used in the transport and delivery of e-mail messages, includes control headers along with the body of messages which, as opposed tother protocols, are not stripped after the message is delivered, leaving a detailed record of e-mail transactions in the recipient mailbox.
Detailed analysis of SMTP headers can be used tmap the networks traversed by messages, including information on the messaging software of clients and gateways. Furthermore, analysis of messages over time can reveal organization patching policies and trends in user location and movements - making headers a very valuable resource during the target selection phase of targeted attacks."

"Introduction:The following presentation is twparts, the first covers aspects of Microsoft's GS implementation and usage. The second is a complementary section dealing with ASLR in Windows Vista, its implementation and some surprising results...
Part I Synopsis: GS is a Visual Studicompiler option that was introduced in Visual Studi2002 tmitigate the local stack variable overflows that resulted in arbitrary code execution. The following paper details the methods Symantec used tassess which binaries within Windows Vista 32bit leveraged GS as a defensive mechanism. This paper presents the results of this analysis, the techniques that have been developed, and supporting material. The results in this paper are from the 32bit RTM release of Microsoft Windows Vista
Part II Synopsis: Address Space Layout Randomization (ASLR) is a mitigation technique designed thinder the ability of an attacker tachieve arbitrary code execution when exploiting software vulnerabilities. As the name implies, ASLR involves placing a computer program and its associated memory at random locations, either between reboots or executions, thinder the attacker's ability treliably locate either their shell code or other required data. This paper is the result of a brief analysis of the implementation of ASLR within Microsoft Windows Vista 32bit RTM, conducted by Symantec's Advanced Threat Research. "

"SS7 has been a walled garden for a long time: only big telcwould be interconnected tthe network. Due tderegulation and a push toward all-IP architecture, SS7 is opening up, notably with SIGTRAN (SS7 over IP) and NGN (Next Gen Networks) initiatives.
SCTP is the protocol used tcarry all telecom signalling information on IP according tthe SIGTRAN protocol suite. It's the foundation, as TCP is the foundation for the web and email. SCTP is alsused for high-performance clusters, resources pooling and very high-speed file transfer.
When you discover open SCTP ports, you discover a secret door tthis walled garden. As a walled garden, the internal security of the SS7 network is not as good as one might expect. SCTPscan is a tool tdexactly just that, and is released as open source.
This presentation will explain how SCTPscan manages tscan without being detected by remote application, how discrepancies between RFC and implementation enable us tscan more efficiently and how we manage tscan without even being detect by systems like SANS - Dshield.org. Here we will have a look at INIT packet construction, stealth scanning and a beginning of SCTP fingerprinting.
Then, we gon tdetail upper layer protocols that use SCTP and the potentials of the SIGTRAN protcol suite in term of security. We'll see the M2UA, M3UA, M2PA, IUA which are SIGTRAN-specific protocols, and alsthe more generic SS7 protocols such as ISUP, BICC, BSSAP, TCAP, SCCP and MTP. "

"n this talk, after briefly reviewing why we should build a good anomaly-based intrusion detection system, we will briefly present twIDS prototypes developed at the Politecnicdi Milanfor network and host based intrusion detection through unsupervised algorithms.
We will then use them as a case study for presenting the difficulties in integrating anomaly based IDS systems (as if integrating usual misuse based IDS system was not complex enough...).
We will then present our ideas, based on fuzzy aggregation and causality analysis, for extracting meaningful attack scenarios from alert streams, building the core of the first 360 anomaly based IDS.
Also, we will introduce some brand new ideas for correlation based on statistical fitting tests."

"This paper will show a extremely simple technique tquickly audit a software product in order tinfer how trustable and secure it is. I will show you step by step how tidentify half dozen of local 0day vulnerabilities in few minutes just making a couple of clicks on very easy tuse free tools, then for the technical guys enjoyment the vulnerabilities will be easily pointed out on disassembled code and detailed, finally a 0day exploit for one of the vulnerabilities will be demonstrated and explained.
While this technique can be applied tany software in this case I will take a look at the latest version of Oracle Database Server: 10gR2 for Windows, which is a extremely secure product sit will be a very difficult challenge tfind vulnerabilities since Oracle is using advanced next generation tools tidentify and fix vulnerabilities."

"Today, other than doing a full static analysis of the code, the most common practice tfind vulnerabilities in your web application is tget off-the-shelf automated web scanner, point ta URL, and hope that it's doing the right thing.
But is it? How dyou know that the scanner exercised all the vital areas of your application? How accurate and complete are the results? Is relying on HTTP response the best way tfind all vulnerabilities in an application? What if there was a way tlook at what's happening inside the application while these web scanners were hitting the application?
In this talk, we'll explore that "looking inside the application as the security test runs" possibility - through byte-code instrumentation. We will see how we can use aspect oriented technologies such as AspectJ tinject security monitors directly inside a pre-compiled Java / .NET web application. We will alsgthrough a proof of concept and dem- turning a typical blackbox test inta "whitebox" test using the techniques discussed in this talk, gaining a more complete picture: gaining coverage insight, finding more vulnerabilities, weeding out false positives reported by the scanners, and gaining root cause source information.
