Immortalising 20 Years of Epic Research

In December 2019 we launched this new technical security research blog site. As part of its launch we had cause to revisit our old blog website and found a myriad of forgotten whitepapers and conference presentations spanning NCC Group’s history (formation in 1999). Deeply nested on our old blog site we found over 200 whitepapers and conference presentations dating as far back as 2001, and which included key outputs from previous cyber security acquisitions including NGS Software (2008), iSEC Partners Inc. (2010), Matasano Security (2012), Intrepidus Group (2012), FortConsult A/S (2014), Fox-IT (2015), Payment Software Company Inc (2016), and VSR Inc. (2016).

While much of the research may not be so relevant anymore due to changes in technology landscapes and a maturation of the cyber security industry; the whitepapers and presentations chronicle much of the foundation of our industry, and at many times show the genesis of ideas and techniques, classes of vulnerability, methods of attack and defence, open source tooling and public reports on key Internet components, and much more. This research has helped our clients with their cyber security assurance needs, and has positively contributed to the security of the Internet as we all know and use it.

There is also sometimes much value in revisiting historical research – this can aid in general learning and development, stimulation of new research ideas and/or re-invigoration of older research ideas that perhaps at the time were theoretical or unfeasible, but are now realisable due to improvements in technology and computational power.

Word cloud created from the whitepaper titles

What a journey its been! With early whitepaper topics covering finding and exploiting format string vulnerabilities in Windows 2000, to more recent topics covering assessment of Unikernel security, and practically every type of technology in between and the security aspects of those technologies.

The research is in no way exhaustive either – many of the public presentations that we have delivered at all manner of Tier-1 conferences around the world over the past 20 years didn’t find their way to our old web site for whatever reason. We have however taken whatever was available and present it here, greppable by title, author, synopsis and year of publication in the table below.

We welcome feedback on additional and relevant things to include in this list and we will happily update the table accordingly.

Just reading the author names in the table is fascinating – many of those individuals are now CISOs, CEOs or senior and influential cyber security professionals in the industry and at some of the largest companies in the world. We are proud of them and their research legacy.

Our current research team continues to build on this legacy as can be seen from their great outputs that we are always excited and proud to showcase on this blog platform. Thank you to everyone who does, and has, contributed to NCC Group’s research and here’s to the next 20 years and the immense research challenges it will bring…

Hackproofing Lotus Domino Web ServerDavid LitchfieldThis document describes how to secure the web service that comes with Lotus Domino. It is written to show Lotus Domino administrators how an attacker would attempt to subvert the security of a Domino Web server and provide insight into the mind and modus operandi of a Domino hacker.2001
Windows 2000 Format String VulnerabilitiesDavid LitchfieldA deep-dive on format string vulnerabilities in Windows 2000.2001
Advanced SQL Injection In SQL Server ApplicationsChris AnleyThis document discusses in detail the common ‘SQL injection’ technique, as it applies to the popular Microsoft Internet Information Server/Active Server Pages/SQL Server platform.2002
More Advanced SQL InjectionChris AnleyThis paper addresses the subject of SQL Injection in a Microsoft SQL Server/IIS/Active Server Pages environment, but most of the techniques discussed have equivalents in other database environments. It should be viewed as a “follow up”, or perhaps an appendix, to the previous paper, “Advanced SQL Injection”.2002
E-mail Spoofing and CDONTS.NEWMAIL – Protecting Microsoft Active Server Pages ApplicationsDavid LitchfieldThis paper will examine how the CDONTS.NEWMAIL object can be used by attackers to send arbitrary e-mails via the vulnerable web server and what must be done to prevent an online ASP application being abused in this way.2002
Assessing IIS Configuration Remotely – Low Level IIS Application AssessmentDavid LitchfieldThis document will look at the relatively unsung skill of assessing the in-depth configuration of a Microsoft IIS web server remotely, showing how to “read” server responses to do this.2002
Hackproofing Oracle Application Server – A Guide to Securing Oracle 9David LitchfieldThis paper will show how an attacker can break into an Oracle-based site, gaining control of the web front end and from there the database server. With each attack explained, the defense against it will be covered.2002
Microsoft SQL Server Passwords – Cracking the password hashesDavid LitchfieldThis paper will discuss the function in detail and show some weaknesses in the way SQL Server stores the password hash. In fact, as we shall see, later on I should be saying, ‘password hashes’.2002
Non-stack Based Exploitation of Buffer Overrun Vulnerabilities on Windows NT/2000/XPDavid LitchfieldThis document will describe what they are and how to write one. As will be seen they are easy to write, more so than traditional stack based overflows and as they only require only an understanding of how functions are called at a low level. The non-stack based buffer overflow exploit writer doesn’t even need to know assembly language.2002
Creating Arbitrary Shellcode In Unicode Expanded Strings – The “Venetian” exploitChris AnleyThe paper is intended to be read by the portion of the security community responsible for creating protective mechanisms to guard against “shellcode” type security flaws; the intention is to remove the perception that Unicode buffer overflows are non exploitable and thereby improve the general state of network security.2002
Violating Database – Enforced Security Mechanisms Runtime Patching Exploits in SQL Server 2000: a case studyChris AnleyThis paper discusses the feasibility of violating the access control, authentication and audit mechanisms of a running process in the Windows server operating systems.

Defeating the Stack Based Buffer Overflow Prevention Mechanism of Microsoft Windows 2003 ServerDavid LitchfieldThis paper presents several methods of bypassing the protection mechanism built into Microsoft’s Windows 2003 Server that attempts to prevent the exploitation of stack based buffer overflows. Recommendations about how to thwart these attacks are made where appropriate.2003
Variations in Exploit methods between Linux and WindowsDavid LitchfieldThis paper will examine the differences and commonality in the way a vulnerability common to
both Windows and Linux is exploited on each system.
New Attack Vectors and a Vulnerability Dissection of MS03-007David LitchfieldThe patch announced by Microsoft on the 17th March 2003 fixed a security vulnerability in the core of the Windows 2000 operating system. The problem, however, is much wider in scope than just simply machines running IIS. Researchers at NGSSoftware have isolated many more attack vectors including java based web servers and
other non-WebDAV related issues in IIS. Due to this, NGSSoftware urge Windows 2000 users to apply the patch.
Quantum Cryptography – A study into the present technologies and future applicationsBill GrindlayIn this report I intend to demonstrate why many scientists now view quantum
cryptography as the first ever completely unbreakable cipher, which will allow people all over the world to communicate securely and privately.
I shall also consider the implications which this will have on society as a whole, including potential problems for law enforcement organisations and the possible
impact on civil liberties.

Slotting Security into Corporate DevelopmentGunter Ollmann
Sherief Hammad
John Heasman
Chris Anley
Technology trail-blazing organisations such as large financial institutions have been working to secure their custom applications for several years, but the second-tier “technology following” organisations have been slow to follow. This is now rapidly changing due to recent bad press following many highly publicised security compromises.2004
Blind Exploitation of Stack Overflow Vulnerabilities – Notes on the possibilities within Microsoft Windows NT based operating systemsPeter Winter-Smith
Chris Anley
This paper presents a number of technical discussion points relating to the potential for exploiting stack overflow vulnerabilities without having direct access to the application which is to be exploited.2004
Passive Information Gathering The Analysis of Leaked Network Security InformationGunter OllmannLike it or not, every Internet-connected system unintentionally leaks internal information about their organisation which could be used to formulate a targeted attack. Depending upon the source of this leakage, the information may relate to the components used within the organisation’s physical asset infrastructure, the ma2004
Second-order Code Injection Attacks – Advanced Code Injection Techniques and Testing ProceduresGunter OllmannA second-order code injection attack can be classified as the process in which malicious code is injected into a web-based application and not immediately executed, but instead is stored by the application and then later retrieved, rendered and executed by the victim.2004
Database Security: A Christmas CarolDavid LitchfieldPresentation2004
An Introduction to Heap overflows on AIX 5.3LDavid LitchfieldIn terms of exploitation, one way to exploit heap overflows is with the “arbitrary 4 byte overwrite”. When the pointers that keep track of heap blocks are updated, an attacker can influence this if they manage to overwrite the inline heap management data.2005
Anti Brute Force Resource Metering – Helping to Restrict Web-Based Application Brute Force Guessing Attacks through Resource MeteringGunter OllmannWhilst commonly proposed solutions make use of escalating time delays and minimum lockout threshold strategies, these tend to prove ineffectual in real attacks and may actually promote additional attack vectors.2005
Database Servers on Windows XP and the Unintended Consequences of Simple File SharingDavid LitchfieldThis paper presents some unexpected consequences of running database servers on Windows XP with
Simple File Sharing enabled
Securing PL/SQL Applications with DBMS_ASSERTDavid LitchfieldOracle has introduced the DBMS_ASSERT PL/SQL package. Whilst integrated into Oracle 10g Version 2 from day one, the DBMS_ASSERT was introduced into 10g Version 1 as part of the October 2005 Critical Patch Update. As a security researcher, it is excellent to see Oracle finally making the right positive moves in the direction of greater security.2005
Security Best Practice: Host Naming URL Conventions Security considerations for web-based applicationsGunter OllmannThere are a number of simple steps that can be
taken to strengthen the security of an environment or application making it more resilient to
several popular attack vectors. By understanding how an attacker can abuse poorly thought
out naming conventions, and by instigating a few minor changes, it is possible to positively
increase the defence-in-depth stature of an environment.
Data-mining with SQL Injection and InferenceDavid LitchfieldSQL Inference is the subject of this paper; this paper is the paper I promised I’d write after talking about this at
the Blackhat Security Briefings in Europe of in the March of 2005. Better late than never!
Stopping Automated Attack Tools – An analysis of web-based application techniques capable of defending against current and future automated attack toolsGunter OllmannThis whitepaper examines techniques which are capable of defending an application against these tools; providing advice on their particular strengths and weaknesses and proposing solutions capable of stopping the next generation of automated attack tools.2005
The Pharming Guide – Understanding Preventing DNS-related Attacks by PhishersGunter OllmannThis paper, extending the original material of “The Phishing Guide”, examines in depth the workings of the name services of which Internet-based customers are dependant upon, and how they can be exploited by Pharmers to conduct identity theft and financial fraud on a massive scale.2005
Writing Small ShellcodeDafydd StuttardThis paper describes an attempt to write Win32 shellcode that is as small as possible, to perform a common task subject to reasonable constraints. The solution presented implements a bindshell in 191 bytes of null-free code, and outlines some general ideas for writing small shellcode.2005
Buffer Underruns, DEP, ASLR and improving the Exploitation Prevention Mechanisms on the Windows platformDavid LitchfieldStarting with Windows 2003 Server, Microsoft introduced a number of Exploitation Prevention Mechanisms (XPMs) into their software. Over time these XPMs were refined as weaknesses were discovered and more XPMs were introduced.2005
Software Penetration TestingBrad Arkin – Symantec
Scott Stender – iSec Partners
Gary McGraw – Cigital
Quality assurance and testing organizations are tasked with the broad objective of assuring that a software application fulfills its functional business requirements. Such testing most often involves running a series of dynamic functional tests to ensure proper implementation of the application’s features.2005
Dangling Cursor Snarfing: A New Class of Attack in OracleDavid LitchfieldWhat is detailed in this document should provide a security reason as to why developers should ensure that cursors are closed properly, especially in the event of an exception.2006
Implementing and Detecting a PCI RootkitJohn HeasmanThis paper discusses means of persisting a rootkit on a PCI device containing a flashable
expansion ROM.
Inter-Protocol CommunicationWade AlcornThis paper explores the Inter-Protocol Communication attack vector. That is, the potential of two different protocols meaningfully communicating commands and data. This has been investigated through encapsulating the target protocol within a carrier protocol. The findings demonstrate that under certain conditions distinct protocols are interoperable.2006
Low Cost Attacks on Smart Cards The Electromagnetic Side-ChannelAdam MatthewsThis paper documents a successful Electromagnetic Analysis attack implemented using limited technical knowledge and low cost equipment. EM traces were
acquired from a sample card and analysis software successfully identified the correct key guesses in proprietary traces.
Which database is more secure? Oracle vs. MicrosoftDavid LitchfieldThis paper will examine the differences between the security posture of Microsoft’s SQL Server and Oracle’s RDBMS based upon flaws reported by external security researchers and since fixed by the vendor in question.2006
Oracle Passwords and OraBrutePaul Wrightoracle-passwords-and-orabrute2007
A Simple and Practical Approach to Input ValidationDavid SolderaInput validation, in theory, is not a difficult problem to solve; it is however a difficult problem to get developers to prioritise security (with regards to other development pressures) and put the time and effort into following good security practice when validating input.2007
Attacking the Windows KernelJonathan LindsayThis paper is focused on Windows and the Intel Architecture, and will briefly outline the current
supervisor boundaries provided. Different attack vectors, along with relevant examples, will be
provided to demonstrate how to attack the supervisor from the perspective of the supervised, as
well as an outline of what possible architectures could be used to mitigate such attacks, such as
the research operating system Singularity.
DNS Pinning and Web ProxiesDafydd StuttardThere are various ways in which DNS-based attacks against web proxies could potentially be prevented through changes to proxy and browser software. Each of the fixes considered suffers from important shortcomings. In the meantime, there are other defences that organisations and individuals can employ to prevent attacks against them.2007
Inter-Protocol ExploitationWade AlcornIn October 2006, this author presented a paper exploring the threat of Inter-Protocol Communication. That is, the possibility of two different applications using two different
protocols to meaningfully exchange commands and data. This paper extends that and other research to explore Inter-Protocol Exploitation. These findings demonstrate the
practicality of encapsulating exploit code in one protocol to compromise a program which uses a different protocol.
Database Security Brief: The Oracle Critical Patch Update for April 2007David LitchfieldOn the 17th April 2007 Oracle released their 10th Critical Patch Update. This brief discusses the database

Oracle database server.
Oracle Forensics Part 2: Locating dropped objectsDavid LitchfieldAs this second paper in the Oracle Forensics series will show, even when an object has been dropped and purged from the system there will be, in the vast majority of cases,
fragments left “lying around” which can be sewn together to build an accurate picture of what the actions the attacker took – or at least some of their actions.
Oracle Forensics: Part 3 Isolating Evidence of Attacks Against the Authentication MechanismDavid LitchfieldIn this section we’ll look at attacks against the
authentication mechanism and evidence from the TNS Listener log file and audit trail, assuming CREATE SESSION is audited of course, and to check whether a logon
attempt was successful or not. We’ll also look at other attacks levelled at the authentication process including SID guessing, user enumeration and brute forcing of
passwords over the network.
Oracle Forensics Part 4: Live ResponseDavid LitchfieldAn organization should have a clear understanding of what actions should be taken in the event of an incident occurring. For those that don’t have a plan often the knee-jerk response is to pull the plug or disconnect the system from the network.2007
Oracle Forensics Part 5: Finding Evidence of Data Theft in the Absence of AuditingDavid LitchfieldThis paper details information about Oracle 10g Release 2 only and should be used as a guideline for investigating other versions of Oracle as no guarantees or assertions can be made about other versions.2007
Oracle Forensics Part 6: Examining Undo Segments, Flashback and the Oracle Recycle BinDavid LitchfieldThis paper examines the ways in which a forensic examiner or incident responder may look for evidence in those places and technologies designed by Oracle for disaster
recovery purposes – namely Undo segments, Flashback and the Recycle Bin – of a compromise and the actions an attacker may have taken.
Exploiting PL/SQL Injection Flaws with only CREATE SESSION PrivilegesDavid LitchfieldWhen exploiting PL/SQL injection flaws in SELECT/UPDATE/INSERT/DELETE statements it has long been known that if an attacker can create their own function, and inject this, then it is possible for them to execute arbitrary PL/SQL code2007
Weak Randomness Part I – Linear Congruential Random Number GeneratorsChris AnleyThis, the first paper in the series, describes the extremely common linear congruential generator and describes a bug in Jetty, a popular Java-based web server, which illustrates some of the dangers described in the paper.2007

Blind Security Testing – An Evolutionary ApproachScott StenderSecurity testing requires that functional testing be covered, for example by ensuring that an authorization mechanism grants or denies access where appropriate, in addition to testing for nonfunctional aspects of the system, a much less tractable test.2007
ProxMon – Automating Web Application Penetration TestingJonathan WilkinsPerforming a web application penetration test is full of repetitive but essential tasks. ProxMon is an extensible Python based framework that reduces testing effort, improves consistency and reduces errors. Its use requires limited additional effort as it processes the proxy logs that you’re already generating and reports discovered issues. In addition to penetration testing, ProxMon is useful in QA, developer testing and regression testing scenarios.2007
Command Injection in XML Signatures and EncryptionBrad HillThis paper describes the vulnerabilities in detail and offers advice for remediation. The most damaging attack is also likely to apply in other contexts where XSLT is accepted as input, and should be considered by all implementers of complex XML processing systems.2007

Tom Ritter
Jon Passki (Aspect Security)
Certain block cipher confidentiality modes are susceptible to an adaptive chosen-ciphertext attack against the underlying format of the plaintext. When the application decrypts altered ciphertext and attempts to process the manipulated plaintext, it may disclose information about intermediate values resulting in an oracle. In this paper
we describe how to recognize and exploit such an oracle to decrypt ciphertext and control the decryption to result in arbitrary plaintext. We also discuss ways to mitigate and remedy the issue.

Further adventures with USBAndy DavisPresentation2012
The Demise in Effectiveness of Signature and Heuristic Based Antivirus: “Or has the death of AV been wildly exaggerated?”NCC Group’s Technical Directors ForumOverall our view is that signature based antivirus is tackling a problem we had 20 years ago and is not relevant to many of today’s threats for businesses, although we feel it still has a role in protecting the consumer. As a result, NCC Group’s opinion is that security budgets might be more effectively directed into other areas of mitigation that offer a higher return on investment in terms of risk reduction.2013
To dock or not to dock, that is the question: Using laptop docking stations as hardware-based attack platformsAndy DavisThis paper details how attackers can exploit the privileged position that laptop docking stations have within an environment.

Advancements in password cracking and frequent theft of password databases endanger single-factor password authentication systems. Password managers are one of the only tools available that can help users remember unique high-entropy passwords, and other secrets such as credit card numbers, for a large number of applications. Can password managers deliver on security promises, or do they introduce their own security vulnerabilities? This paper examines popular browser-based password managers and presents common security flaws that could be exploited to remotely extract a user’s password.2013

XML Schema, DTD, and Entity Attacks
A Compendium of Known Techniques
Timothy D. Morgan and Omar Al IbrahimThe eXtensible Markup Language (XML) is an extremely pervasive technology used in countless software projects. A core feature of XML is the ability to define and validate document structure using schemas and document type definitions (DTDs).
