Invited Talks

"Cross-Domain Theft and the Future of Browser Security"

Appsec research 2010 invited talk 1.jpg

Chris Evans
Troublemaker, Information Security Engineer, and Tech Lead and Google inc.
The sole author of vsftpd.

Ian Fette
Product Manage for Chrome Security and Google's Anti-Malware initiative

Abstract
The web browser, and associated machinery, is on the front line of attacks. We will first look at design-level problems with the traditional browser in terms of monolithic architecture and fundamental problems with the same-origin policy. We will then look at the types of solution that are starting to appear in browsers such as Google Chrome and Internet Explorer. We will look at other important browser-based defenses such as Safe Browsing. We will detail what a future browser might look like that has a much more secure design, but is still usable on the wide variety of web sites that people use daily.

"The Security Development Lifecycle -- The Creation and Evolution of a Security Development Process"

Appsec research 2010 invited talk 2.jpg

Steve Lipner
Senior Director of Security Engineering Strategy, Trustworthy Computing Security, Microsoft Corporation.
Co-author of "The Security Development Lifecycle", Microsoft Press (book cover above).

Abstract
This keynote will review the evolution of the Security Development Lifecycle (SDL) from its origins in the Microsoft “security pushes” of 2002-3 through its current status and application in 2010. It will emphasize the aspects of change and change management as the SDL and its user community have matured and grown and will conclude with a summary of some recent changes and additions to the SDL. Specific topics to be addressed include:

  • Motivations for introducing both the SDL and its predecessor processes.
  • Considerations in selling the process to management and sustaining a mandate over a prolonged period.
  • Scaling the SDL to an organization with tens of thousands of engineers.
  • Managing change.
  • The role of automation in the SDL.
  • Adaptation of the SDL to agile development processes.
  • Thoughts for organizations that are considering implementing the SDL.

The presentation will cover technical aspects of the SDL including a brief review of requirements and tools, and results.

Speaker Bio
Steven B. Lipner is senior director of Security Engineering Strategy at Microsoft Corp where he is responsible for programs that provide improved product security for Microsoft customers. Lipner leads Microsoft’s Security Development Lifecycle (SDL) team and is responsible for the definition of Microsoft’s SDL and for programs to make the SDL available to organizations beyond Microsoft. Lipner is also responsible for Microsoft’s corporate strategies related to government security evaluation of Microsoft products. Lipner joined Microsoft in 1999 and was initially responsible for the Microsoft Security Response Center. In the aftermath of the major computer “worm” incidents of 2001, Lipner and his team formulated and led programs that helped customers respond to the immediate challenges posed by software vulnerabilities and Internet worms. Lipner and his team also devised the strategy of “security pushes” that, as part of the Trustworthy Computing initiative, enabled Microsoft to make rapid improvements in the security of its software products and to change the corporate development culture to emphasize product security. The SDL is the product of these improvements, and is widely viewed as the industry’s leading secure software development process.

Before joining Microsoft, Lipner worked for a variety of software vendors and government contractors as a researcher, consultant, development manager and general manager in IT security. Many of the concepts whose development he led form the basis for today’s approaches to building secure systems. Some examples of these contributions include the application of virtual machine monitors (VMMs) as an approach to isolating security domains, and mathematical models for multilevel security.

Lipner is coauthor with Michael Howard of The Security Development Lifecycle (Microsoft Press, 2006) and is named as inventor on twelve U.S. patents and two pending applications in the field of computer and network security. He has authored numerous professional papers and conference presentations, and served on several National Research Council committees. He served two terms – a total of more than ten years – on the United States Information Security and Privacy Advisory Board and its predecessor. Lipner holds S.B. and S.M. degrees in Civil Engineering from the Massachusetts Institute of Technology and attended the Harvard Business School’s Program for Management Development.

Training

Training

Registration for training will open within a few days. The price will be €990 (~$1.350) for a two-day course. Take a chance to learn from these excellent appsec trainers!

Course 1: Threat Modeling and Architecture Review (two days)

AppSec Research 2010 Pravir Chandra.jpg

Pravir Chandra, Fortify Software

Abstract: Threat Modeling and Architecture Review are the cornerstones of a preventative approach to Application Security. By combining these topics into single comprehensive course attendees can get a complete understanding of how to understand the threat an application faces and how the application will handle those potential threats. This enables the risk to be accurately assessed and appropriate changes or mitigating controls recommended.

Trainer Bio: Pravir Chandra is Director of Strategic Services at Fortify where he works with clients to build and optimize software security assurance programs. Pravir is widely recognized in the industry for his expertise in software security and code analysis, and also for his ability to apply technical knowledge strategically from a business perspective. His book, Network Security with OpenSSL is a popular reference on protecting software applications through cryptography and secure communications. His varied special project experience includes creating and leading the Open Software Assurance Maturity Model (OpenSAMM) project

Course 2: Introduction to Malware Analysis (two days)

AppSec Research 2010 Jason Geffner.jpg

Jason Geffner, Next Generation Security Software (NGS), and Scott Lambert, Microsoft

Abstract: Security researchers are facing a growing problem in the complexity of malicious executables. While dynamic black-box automation tools exist to discover what malware will do on a given execution, it is often important for an analyst to know the full capabilities of a given malware sample. What port does it listen on? What password does it expect for backdoor access? What files will it write to? What will it do tomorrow that it didn't do today? This class will focus on teaching attendees the steps required to understand the functionality of given malware samples. This is a hands-on course. Attendees will work on real-world malware through a series of lab exercises designed to build their expertise in understanding the analysis process.

Trainer Bio: Jason Geffner joined Next Generation Security Software Ltd. in June of 2007 as a Principal Security Consultant. Jason focuses on performing security reviews of source code and designs, reverse engineering software protection methods and DRM protection methods, deobfuscating and analyzing malware, penetration testing web applications and network infrastructures, and developing automated security analysis tools.

Course 3: Introduction to Malware Analysis (two days)

AppSec Research 2010 Dave Wichers.jpg

Dave Wichers, Aspect Security

Abstract: Students gain hands-on testing experience with freely available web application security test tools to find and diagnose flaws and learn how to identify them in their own projects. Because finding flaws is worthless without effective communication, the course also covers the process of creating and communicating software security flaws effectively. In addition, Aspect’s engineers are leaders in the AppSec Community and will offer the students an amazing perspective.

Trainer Bio: Dave Wichers is a member of the OWASP Board and a coauthor, along with Jeff Williams, of all previous versions of the OWASP Top Ten. Dave is also the Chief Operating Officer of Aspect Security, a company that specializes in application security services. Mr. Wichers brings over twenty years of experience in the information security field. Prior to cofounding Aspect, he ran the Application Security Services Group at a large data center company, Exodus Communications. His current work involves helping customers, from small e-commerce sites to Fortune 500 corporations and the U.S. Government, secure their applications by providing application security design, architecture, and SDLC support services: including code review, application penetration testing, security policy development, security consulting services, and developer training.

Course 4: Assessing and Exploiting Web Apps with Samurai-WTF (two days)

AppSec Research 2010 Justin Searle.jpg

Justin Searle, InGuardians

Abstract: This course will focus on using open source tools to perform web application assessments. The course will take attendees through the process of application assessment using the open source tools included in the Samurai Web Testing Framework Live CD (Samurai-WTF). Day one will take students through the steps and open source tools used to assess applications for vulnerabilities. Day two will focus on the exploitation of web app vulnerabilities, spending half the day on server side attacks and the other half of the day on client side attacks. The latest tools and techniques will be use throughout the course, including several tools developed by the trainers themselves.

Trainer Bio: Justin Searle, a Senior Security Analyst with InGuardians, specializes in web application, network, and embedded penetration testing. Justin has presented at top security conferences including DEFCON, ToorCon, ShmooCon, and SANS. Justin has an MBA in International Technology and is CISSP and SANS GIAC-certified in incident handling and hacker techniques (GCIH) and intrusion analysis (GCIA). Justin is one of the founders and lead developers of Samurai-WTF.

Course 5: Securing Web Services (two days)

AppSec Research 2010 Jason Li.jpg

Jason Li, Aspect Security

Abstract: Aspect Security offers a one or two day course titled Securing Web Services designed to focus on the most important messages regarding the development and of secure web services. The objective for this course is to ensure that developers understand the real risks associated with Service Oriented Architectures, what standard are available to help, and how to use the standards. The course includes a combination of lecture and demonstration designed to provide detailed guidance regarding the implementation of specific security principles and functions.

Trainer Bio: Jason Li is a Senior Application Security Engineer for Aspect Security where he performs application security assessments and architecture reviews, as well as application security training, to a wide variety of financial and government customers. Jason is an active OWASP leader, contributing to several OWASP projects and serving on the OWASP Global Projects Committee.

Challenges

Countdown Challenges -- Free Tickets to Win!

There will be a challenge posted on the conference wiki page the 21st every month up until the event. The winner will get free entrance to the conference. Be sure to sign up for the conference mailing list to get a monthly reminder.

AppSec Research Challenge X: Build an Enterprise Java Rootkit

The tenth challenge is here!

Jeff Williams, chairman of OWASP, gave a very interesting talk at last year's Black Hat US and OWASP AppSec US -- "Enterprise Java Rootkits -- Hardly Anyone Watches the Developers". Now it's time for you to write a rootkit yourself, exploring Jeff's techniques and more.

The Project to Fool
Your assignment is to be the evil developer who implements and hides a backdoor in a Java servlet. We've implemented a very simple login web application and exported the Eclipse project (zip here). We will use this project to evaluate your submissions. It's a simple servlet/jsp project that we deployed on Tomcat 6.0. It even contains an evil output of user credentials to a temp file (not yet hidden though) to get you started. Screenshot from the app and the project structure:


Appsec research 2010 challenge X eclipse project.jpg Appsec research 2010 challenge X login screen.jpg

Rules

  • You must explain what your changes do (we need to evaluate your rootkit!)
  • The original features + look and feel must be preserved
  • Your additions should preferably look like security features such as IP whitelisting, logging, anti-CSRF, frequency blocking etc.
  • You're only allowed to change the servlet (Login.java), and the gif image (appsec_research_challenge_X.gif)
  • You do not have to use the jsps
  • The original size of Login.java is 1,856 bytes and it mustn't grow to more than 4,000 bytes
  • The gif image mustn't grow in size and should look close enough to the original to fool the committee
  • Code should "look" readable, i e not minimized too heavily

How To Win
The organization committee will evaluate who has been able to hide the most evil stuff while complying to the rules. The more malicious functionality and the more clever disguise -- the more "points". All submissions must be posted as links or pasted code in this sla.ckers.org thread. Send an email to [email protected] when you post code or need attention. Deadline April 20.


AppSec Research Challenge 9: Crack 'Em Hashes

February's AppSec Research 2010 challenge is about breaking hashed passwords. It starts off easy with the old LM hash and ends with SHA256 and GOST3411.

Owasp appsec research 2010 hash challenge.jpg

How To Win
The first one to publish each broken password gets points according to the table below but at the same time helps the others since the password is the salt of the next hash. So you have to decide -- should you publish your cracked password and collect your points before the others or should you keep it a secret to get a head start cracking the next one? Deadline it March 21st.

To collect points for a password you must be the first one to publish that broken password on this sla.ckers.org thread. Please send an email to [email protected] at the same time so we can correct any misunderstandings. For instance we can happen to run into hash collisions, where someone finds another mixed alpha password of max 5 characters that concatenated with the right salt produces the same hash. In such a case we will publish the real password and give points to the one who found the collision.

The one with the most points on March 21st wins a free ticket to the conference!

Points to Earn

  • pwd1 (LM) => 1 point
  • pwd2 (MD2) => 3 points
  • pwd3 (MD4) => 5 points
  • pwd4 (MD5) => 9 points
  • pwd5 (RIPEMD160) => 15 points
  • pwd6 (SHA1) => 25 points
  • pwd7 (SHA256) => 50 points
  • pwd8 (GOST3411) => 100 points

The Hashes
Each password comprises of a-zA-Z (mixed alpha) and is max 5 characters long. With salt that means max 10 mixed alpha characters as input to the hash function. All hashes here are in hex format. The Java source code has all the details. The plus operator means string concatenation.

  • LM(pwd1) 0C04DACA901299DBAAD3B435B51404EE
  • MD2(pwd2 + pwd1) 16189F5462BF906E9D88CF6F152DE86F
  • MD4(pwd3 + pwd2) FA8F46A6D347087D6980C3FA77DD4DE9
  • MD5(pwd4 + pwd3) 425B33D6F60394C897B8413B5C185845
  • RIPEMD160(pwd5 + pwd4) 35F34671D30472D403937820DCABC1C78C837071
  • SHA1(pwd6 + pwd5) AE81A30510B2931921934218636B26A803330EB1
  • SHA256(pwd7 + pwd6) B2FF0269E927C6559804A37590A0688C45DF143F85CEE0E3F239F846B65C9644
  • GOST3411(pwd8 + pwd7) 16CC9F1FF65688E040F5ADA82A41A258FF948769CDA4C4A17D85228A6F358971

Example: Given that pwd1 is "Win" and pwd2 is "You", the hash 16189F5462BF906E9D88CF6F152DE86F is the result of MD2("YouWin"). Now pwd2 will be the salt when you crack pwd3.

The Source Code
The source code we've used to produce the hashes is available here zip. It's Java and all but the LM hash is done with Bouncy Castle 1.4.5.


AppSec Research Challenge 8: Construct an OWASP Polyglot

January's AppSec Research Challenge is to construct an OWASP polyglot, more specifically an OWASP logo that also can be run as JavaScript:

Show image: <img src="owasp_logo.gif">
Run script: <script src="owasp_logo.gif"></script>

Wikipedia says: "a polyglot is a computer program or script written in a valid form of multiple programming languages". This is about as cool as it gets :).

Rules

  • Make your polyglot out of the regular OWASP logo in the upper left corner of this wiki (circle with the wasp).
  • The file size must not grow.
  • Pixel colors in the gif must not differ more than 5 in red, green, or blue. Ex: If a pixel originally had rgb 100,100,100 then 104,95,96 is OK.
  • No malicious stuff of course
  • When your polyglot is run as JavaScript it should execute as many of the following features as possible, starting from the top:
  1. alert(all cookies belonging to the current domain);
  2. alert(the last keystrokes on the keyboard every ten keystrokes);
  3. alert(the current time in Stockholm, once every minute);
  4. A quine. The polyglot outputs its own source code on the HTML page.

How to get started

Jasvir Nagra gave a talk on these kind of polyglots and published a gif/JavaScript polyglot on his blog. A good starting point is his gif file. Jasvir has also written an extensive article on gif/perl polyglots which explains how to get code into the gif file. Check out his guide.

How to win

Submit your entries in this sla.ckers.org thread. Either the first complete polyglot or the most complete polyglot wins. We will most probably provide you with a gif checker that validates the color differences. Check the thread. 

AppSec Research Challenge 7: X-Mas Capture the Flag

AppSec Research 2010 Stocking.gif Merry Christmas everyone!AppSec Research 2010 Stocking.gif

It's the 21st and a new AppSec Research Challenge is posted.

Setting up the AppSec Research 2010 X-mas Challenge was a cooperative effort by the winner of AppSec Research Challenge 3, Mario Heiderich, and Martin Holst Swende. It is a multi-step challenge which involves finding a vulnerability in a web application and locating a hidden message. The winner gets free entrance to next year's conference. Start by subscribing to the conference mailing list. Then check the simple rules below and get going.

Rules:

  • Please do not perform any resource-intensive tests, as the machine is pretty low-end and can be DoS:ed without much effort.
  • The computer at the given IP address is the only system involved in this challenge, so please do not perform any tests of neighboring systems.
  • Otherwise, you are free to hack away!

Challenge-page: 66.249.7.26

Discussions, QnA and reports about how far you have made it is welcome at the official sla.ckers thread.

Good luck and happy holidays! (And don't forget the submission deadline for the conference -- February 7)


Note: This challenge is re-opened. Submit by February 21st.

November's AppSec Research 2010 Challenge asks you to design the conference logotype. So far we have used this:

Appsec research 2010 logo prototype (small).png

... but would like something less "word processor-like".

How to win

  • The logo should be suitable for both large printing and small web banners
  • If you make a color logo, please submit a b/w version too
  • "OWASP AppSec Research 2010" should in some way be part of the logo :)

Copyright?
By submitting your logo you agree to share it according to Creative Commons Attributions and that we credit you in the conference brochure and on the conference wiki but not in all places where we use the logo (i e we will not credit you on banners, sponsoring program, powerpoint presentations etc).

How to submit
Email jpg + svg to john.wilander [at] owasp.org before Monday December 14th 23:59 UTC. The creator of the best logo wins a free ticket to the AppSec Research 2010 conference!

AppSec Research Challenge 5: Graphical Effects

The October OWASP AppSec Research 2010 challenge is over. The winner of a free entrance ticket to next year's AppSec conference in Stockholm is "sirdarckcat" with FireworksIsNotABrowser_v4 (although we like the slightly oversized v6 better).

The challenge was about writing the coolest graphical effect in a 2010 character script.

An Example

As an example, copy the script below and paste the script over the URL in the URL bar.

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval('A()',5); void(0)

As a simple teaser we give these png letters for the script to play with.

AppSec Research 2010 O.pngAppSec Research 2010 W.pngAppSec Research 2010 A.pngAppSec Research 2010 S.pngAppSec Research 2010 P.png

Rules

  • The script should work in Firefox 3.5 (yeah, that means HTML5 and CSS3 :)
  • Any resource, linked document, script, or image defined on the AppSec Research 2010 wiki page may be loaded/accessed/used
  • No requests to any other location is allowed
  • No obfuscation is allowed
  • The script may only use ASCII
  • Max length of the script is 2010 characters
  • You have to give your effect an id and a version number (further explanation below)
  • Any form of malicious code is of course banned ;)

How to Compete

There's an official thread on sla.ckers were you share your code and thoughts (Worried someone will steal you code? Check the originality bullet below). You can enter as many effects as you like but each effect has to have an id and a version number, e.g. JohnWobbler_v1.3 for version 1.3 of John's Wobbler effect. Deadline is November 14th, 23:59 UTC.

Choosing the Winner

Since this is a creative challenge the OC will choose the winner based on the following:

  • Originality (tweaking someone's code is cool and encouraged but changing a few magic numbers or inverting a function won't make you the winner)
  • Coolness (yeah, you need to convince a few Scandinavian people + Seba and Kate that your script is the coolest)

Either the OC will choose a winner by ourselves or we choose the top effects and let you guys vote for the winner.

AppSec Research Challenge 4: Who's Who in Security?

September's AppSec Research 2010 Challenge was to identify a number of people that are, in one way or another, known in the security business, by their picture. There were thirteen photos in total, portraiting thirteen different individuals.

The winner of a free ticket to the OWASP AppSec Research conference in 2010 was Thomas Vollstädt who submitted the correct solution just one day after the challenge was posted.

AppSec Research Challenge 3: Non-Alphanumeric JavaScript

The August AppSec Research 2010 Challenge was to create a JavaScript alert("owasp") that pops up the word 'owasp', case-insensitive, without using any alphanumeric characters (0-9a-zA-Z). There was a tremendous activity and we want to thank everyone who participated. The size of the final result was almost a third of the first entry (see chart below). Want to check out the winning snippet by .mario? Enter the following in the Firebug console: ω=[[Ṫ,Ŕ,,É,,Á,Ĺ,Ś,,,Ó,Ḃ]=!''+[!{}]+{}][Ś+Ó+Ŕ+Ṫ],ω()[Á+Ĺ+É+Ŕ+Ṫ](Ó+ω()[Ḃ+Ṫ+Ó+Á]('Á«)'))

It is based on a few different ideas. First of all, a variable assignment on the form

[a,b,c,,e]="abcde" // a="a", c="c",e="e"

Which is performed on the string "truefalse[object Object]"

[Ṫ,Ŕ,,É,,Á,Ĺ,Ś,,,Ó,Ḃ]=!''+[!{}]+{}] // right-hand side is "truefalse[object Object]"

Also, the following construction obtains the window.sort-function, which leaks the window-object when called without arguments :

ω=[]["sort"] //ω is now window.sort

Therefore, calling ω()["alert"] invokes window.alert. To generate the string "owasp", the string "wasp" can be obtained by calling btoa on the characters "Á«)".

This was really a great team effort, and I think a lot of us learned some new tricks. The final winner was .mario. Congratulations!

JavaScript Without Alphanumeric Characters?

It is possible to write valid javascript completely without alphannumeric characters (0-9a-zA-Z). To produce a number, you can instead use for example an empty string, '', interpret it as a boolean with a bang: !'' -- which leads to the boolean object true. true, interpreted as a numeric value, equals one. Thus,

$ = +!''; // $ === 1

$++;$++; // $ === 3

In a similar fashion, strings can be created from strings embedded in the language. The boolean object true can be converted to string by concatenation, and then accessed by numeric index to, for example, produce the letter 'e' :

â = (!''+'')[$] // â[$] === "true"[3] === e

Previous Similar Contest

These two techniques are behind a previous contest at the forum "sla.ckers.org", where the contest was to create alert(1) with as few non-alphanumeric characters as possible. Currently, the code actually being executed was:

([],"sort")()["alert"](1) // since ([],"sort")() leaks window object in FF, ==> window["alert"](1) is called, which is another form of window.alert(1)

The winner, or at least current leading entry is 84 bytes long, and looks like this:

(Å='',[Į=!(ĩ=!Å+Å)+{}][Į[Š=ĩ[++Å]+ĩ[Å-Å],Č=Å-~Å]+Į[Č+Č]+Š])()[Į[Å]+Į[Å+Å]+ĩ[Č]+Š](Å)

The Challenge

August's challenge was to, in a similar fashion, create an alert("owasp"), case-insensitive, not using any alphanumeric characters. The shortest working code snippet submitted by September 18th 23:59:59 UTC won a free ticket. By "working" we meant JavaScript that executes in Firefox/Firebug, not depending on any Firebug DOM variables for execution.

AppSec Research Challenge 2: OWASP Crossword Puzzle

July's crossword challenge is over. Many permutations arrived in our inbox but it was tricky to get it completely right. Congratulations to Johannes Dahse and Johan Nilsson who in the end were allowed to join forces to be able to find the correct solution. They win a 50 % conference ticket discount each.

You find the solution below.

AppSec Research Challenge 1: Input Validation and Regular Expressions

This challenge is over. The winner was Partik Nordlén. To see the solution(s), please visit the appsec_eu_2010 mailing list archive.

Some people, when confronted with a problem, think “I know, I'll use regular expressions.” Now they have two problems.
        --Jamie Zawinski, in comp.emacs.xemacs

The 21st of each month up until the conference in June 2010 we'll have a countdown challenge posted here. The winner each month will get a free entrance ticket worth about €300/$400. Be sure to sign up for the conference mailing list to get a monthly reminder.

The Challenge

A community is hosted on a very large domain, yahoogle.com. The users of that community all have profiles, where they are allowed to use basic HTML for customization, as well as JavaScript files hosted on the domain.

All the code for the profile pages are filtered on the server side, and whenever a piece of code containing "<script..." is encountered, the following regular expression is used to validate that the script loaded is hosted on a subdomain of yahoogle.com:

.*(<script){1}([^>]+)src=('http:\/\/[a-zA-Z]+.yahoogle.com\/scripts\/[0-9A-Za-z]+\.js').*\/>

Capture group 3 is then also checked against a whitelist of allowed scripts on that domain. The whitelist consists of "http://secure.yahoogle.com" and "http://scripts.yahoogle.com".

Your task is to formulate a snippet of HTML that goes correctly through the filter and the whitelist, but loads the script "http://insecure.com/evil.js" instead. Also, rework the regular expression to defend against your "attack".

Email your solution to Martin Holst Swende <[email protected]>. The first correct answer wins a free ticket to the conference. The free ticket is personal and the judgement of the organizing committee can not be overruled :).

Call for Papers and Proposals (closed)

AppSec Research 2010 2nd cfp.png


1. Publish or Perish. Peer-reviewed 12 page papers to be published in formal proceedings by Springer-Verlag (Lecture Notes in Computer Science, LNCS). Presentation slides and video takes will be posted on the OWASP wiki after the conference.
2. Demo or Die. A demo proposal should consist of a pdf with a 1 page abstract summarizing the matter proposed by the speaker(s) and 1 page containing demo screenshot(s). Demos will have ordinary speaker slots but the speakers are expected to run a demo during the talk (live coding counts as a demo), not just a slideshow. Presentation slides and video takes will be posted on the OWASP wiki after the conference.
3. Present or Repent. A presentation proposal should consist of a 2 page extended abstract representing the essential matter proposed by the speaker(s). Presentation slides and video takes will be posted on the OWASP wiki after the conference.

If you have any questions regarding submissions etc, please email [email protected]
