OWASP Hong Kong
OWASP Foundation (Overview Slides) is a professional association of global members and is open to anyone interested in learning more about software security. Local chapters are run independently and guided by the Chapter_Leader_Handbook. As a 501(c)(3) non-profit professional association your support and sponsorship of any meeting venue and/or refreshments is tax-deductible. Financial contributions should only be made online using the authorized online chapter donation button. To be a SPEAKER at ANY OWASP Chapter in the world simply review the speaker agreement and then contact the local chapter leader with details of what OWASP PROJECT, independent research or related software security topic you would like to present on.
Or consider the value of Individual, Corporate, or Academic Supporter membership. Ready to become a member?
The Hong Kong chapter was formed in December 2004. The objectives to establish OWASP Hong Kong Chapter are mainly because: -There are many web applications established in past 10 years. However, how many developers know that their developed application are secure. Meanwhile, there are many transactional-based systems, we should not ignore that the web application is another channel for hackers to compromise one's confidential information and interrupt any critical business operations.
- Raise the security awareness of web application development among the professionals.
- Encourage professionals to reference standard like ISO7799 for their web application security and post-deployment review as well as audit.
- Accelerate to Share, learn, discuss and review best practices of the experienced web application development security professionals even across various user groups (Java User Group and .NET User Group ) and security associations (i.e. PISA) in Hong Kong.

- Mainstream web technologies (i.e. .NET, J2EE and PHP on Linux) security assessment
- Web application platform (i.e. Apache, IIS, Linux, Database) security assessment and review.
- Recent Web application security concerns.
- Regularly convey latest projects and presentations from OWASP.
News from Hong Kong Chapter
Chapter meeting on Jan-19, 2012: "Securing the SSL channel against man-in-the-middle attacks: Future technologies - HTTP Strict Transport Security and and Pinning of Certs"
I have arranged a seminar on 19 Jan 2012 from Tobias from OWASP London Chapter from 1900 to 2000 at HK Polytechnic University.I would like to invite OWASP, PISAM, ISOC-HK, HK Software Exploitation and VXRL fellows to attend to it:
Topic: HSTS and Pinning of Certs (defending against CA private key compromises - learnings from the DigiNotar breach):
Description: This is cutting edge and will talk about new technologies that will be coming up in the coming months to counter risks that became apparent from the current trust model used in browsers with hundreds of equally trusted CAs and its vulnerability to a breach of a single individual CA.
Presenter: You could find his profile from here and he is readily a great and nice researcher indeed. He has presented talks in Appsec Beijing and Europe before: https://www.owasp.org/index.php/User:Tgondrom
Synopsis: "Securing the SSL channel against man-in-the-middle attacks: Future technologies HTTP Strict Transport Security and and Pinning of Certs In the recent months major trusted CAs providing trusted certificates for SSL/TLS in browser scenarios were compromised (e.g. seen in the Diginotar breach) and based on the current trust models (trusting all registered CAs equally for all domains) exposed vital web applications to the risk of man-in-the-middle attacks. Several approaches are currently discussed to mitigate this risk. The most advanced and closest to final adoption being the technologies discussed by the browser vendors at the recent IETF meeting in November in Taipei: HSTS and pinning of certificates. To better protect content providers against the distribution of bogus certificates, an HTTP header extension containing a fingerprint of their certificates linked to a domain address has been defined. This approach, which has been partly tested in Chrome, and already helped identify and protect to some extend Google's web application in the recent Diginotar compromise. Chrome users were able to detect the bogus DigiNotar certificates because Chrome had embedded the hashes of valid Google certificates. Back in July, the hacked DigiNotar certificate authority (CA), which has since gone out of business, was used to issue more than five hundred bogus certificates for companies including Google and various intelligence services.
The presented technology is cutting edge and although the specification is not final yet, it will be rolled-out in about 6 months time. Two other models that compete or complement this approach will also be discussed (DNSSEC and Moxie's Convergence)."
NEW!!!! Software Exploitation - It is about reverse engineering and exploit
I feel very honorable to invite Nguyen NAM to provide 2-day workshop on software exploit and reverse engineering. In fact, we met in OWASP Appsec Conference 2008 at Taipei and his team has won CTF (Capture The Flag) in Hack In The Box (HITB) 2008. It is really a valuable chance to have him to be in Hong Kong and this workshop is normally charged at 1000 USD per head. Meanwhile, there is NO such kind of workshop held in Hong Kong. Please reach me at email@example.com for reservation.
Status - 16 Dec 2008 : The speaker will arrive on 19 Dec and please bring USB storage more than 8GB to copy the VM for practice later on) Please act fast to reserve it first and the current reservation is 30. The class size is expected to be at most 35.
1) Send the payment to: Hang Seng Bank, 390-031367-888 and then send back the receipt to firstname.lastname@example.org and email@example.com
2) Please reach me if you have enquiry at +852 6778 2668.

Summary This course is a primer into software exploitation on the Linux environment. The course assumes only basic understanding of the Linux commands, and C programming with the standard library. It explains the computer architecture, assembly language then moves on to three basic classes of security bug: buffer overflow, format string, and race condition and methods to take advantage of them. Throughout the course, various examples are introduced with increasing difficulty so that participants will naturally realize the art of software exploitation for themselves.
This course does not discuss about shell coding. Except on one example where provided shell code is used as an illustration, all other challenges require only good analysis and calculation.
The course is conducted as a workshop with heavy interaction between participants and instructor. There will not be any presentation slide. Participants are to take note during the course.
Software developers, system administrators, security engineers \with some experience in Linux and C programming. It is good to prepare a candidate to join for Capture The Flag (CTF) event.
