This document summarizes Stefano di Paola's talk on security issues with JavaScript libraries. It discusses how jQuery's $() method can be considered a "sink" that executes HTML passed to it, including examples of XSS via jQuery selectors and AJAX calls. It also covers problems with JSON parsing regular expressions, AngularJS expression injection, and credentials exposed in URLs. Solutions proposed include validating all input, auditing third-party libraries, and moving away from approaches like eval() that execute untrusted code.
This document summarizes Bruno Gonçalves de Oliveira's talk on hacking web file servers for iOS. It introduces Bruno and his background in offensive security and discusses how iOS devices store a lot of information and mobile applications are often poorly designed and vulnerable. It provides examples of vulnerable file storage apps, outlines features and vulnerabilities like lack of encryption, authentication, XSS issues, and path traversal flaws. The document demonstrates exploits like unauthorized access to file systems on jailbroken devices and how to find vulnerable systems through mDNS queries. It concludes that mobile apps are the future but designers still do not prioritize security and there are too many apps for users to vet carefully.
Agile 2012 the 0-page agile test plan - paul carvalhodrewz lin
The document discusses moving to an agile test plan approach. It suggests ditching traditional test plans and instead focusing on what information provides value to stakeholders. The document provides a template for a lightweight test strategy, including naming the test strategy, listing features and environments, identifying personas or quality attributes of interest, and the date. It also suggests generating test charters from the strategy and committing to applying the lessons by exchanging contact information with another attendee.
The document discusses maintaining high-quality acceptance tests. It provides 5 principles: 1) Treat tests like production code, 2) Interact with the system under test like a user, 3) Continuously curate user journeys, 4) Have collective ownership of acceptance tests, 5) Tests own their own data. The presentation emphasizes that quality is a shared responsibility and tests require ongoing care like production code. Exhaustive story-level testing alone does not lead to maintainable test suites.

Web security-–-everything-we-know-is-wrong-eoin-kearydrewz lin
1) Web application security is often approached incorrectly, focusing too much on annual penetration tests and compliance, rather than ongoing monitoring and prevention through the development process.
2) Many vulnerabilities are introduced through third party libraries and dependencies, which are not properly tested or managed. Continuous testing across the full software supply chain is needed.
3) Not all vulnerabilities are equal - context is important. A risk-based approach should prioritize the most critical issues based on factors like impact, likelihood, and the development environment. Compliance alone does not ensure real security.
This document summarizes a presentation about the mobile security Linux distribution Santoku Linux. It discusses how Santoku Linux was created by modifying Lubuntu to include mobile forensic and security tools from the company viaForensics. Some key tools discussed include AFLogical OSE for Android logical acquisitions, iPhone Backup Analyzer, and utilities for analyzing mobile malware samples. Real-world examples of analyzing the Any.DO task manager app and Korean banking malware are also provided.
This document discusses sandboxing untrusted JavaScript from third parties to improve security. It proposes a two-tier sandbox architecture that uses JavaScript libraries and wrappers, without requiring browser modifications. Untrusted code is executed in an isolated environment defined by policy code, and can only access approved APIs. This approach aims to mediate access between code and the browser securely and efficiently while maintaining compatibility with existing third-party scripts.
This document discusses how HTML5 features can be used for authentication purposes and addresses some security challenges. It describes APIs like local storage, canvas, geolocation, and notifications that could be leveraged for authentication factors like passwords, patterns, and one-time passwords. However, it also notes risks like storing sensitive data on devices, spoofing locations, and notifications not being reliable. The document advocates using HTML5 responsibly and understanding privacy and user behavior when designing authentication solutions.

It provides the methodology for conducting code reviews, which includes gaining access to source code, understanding the technology, threat modeling, analyzing the code, and creating automation scripts. Finally, it discusses specific vulnerabilities that may be found in Windows Phone, hybrid, Android, and iOS applications.
The document discusses research conducted by Gregg Ganley and Gavin Black at MITRE in FY13-14 on iOS mobile application security. It describes their work on a tool called iMAS (iOS Mobile Application Security) which aims to provide additional security controls and containment for native iOS applications. iMAS addresses vulnerabilities related to runtime access, device access, application access, data at rest, and threats from app stores/malware. It utilizes techniques like encrypted code modules, forced inlining, secure MDM and more to raise security levels above standard iOS but below a fully customized/rooted mobile device environment. The document outlines the motivation, capabilities and future research directions for the iMAS project.
Defeating xss-and-xsrf-with-my faces-frameworks-steve-wolfdrewz lin
This document discusses how to defeat cross-site scripting (XSS) and cross-site request forgery (XSRF) when using JavaServer Faces (JSF) frameworks. It covers validating user input, encoding output, and protecting view states to prevent XSS, as well as configuring JSF implementations to protect against XSRF by encrypting view states and adding tokens to URLs. The presentation emphasizes testing validation, encoding, and protection in specific JSF implementations since behaviors can differ.
This document summarizes a presentation on defending against CSRF (cross-site request forgery) attacks. It discusses four main design patterns for CSRF defenses: the synchronizer token pattern, double submit cookies, challenge-response systems, and checking the referrer header. It then provides details on implementing these patterns, specifically looking at libraries and features in .NET, .NET MVC, Anticsrf, CSRFGuard, and HDIV that can help implement CSRF tokens and validation. The document covers the tradeoffs of different approaches and considerations for using them effectively on the code and server level.
Chuck willis-owaspbwa-beyond-1.0-app secusa-2013-11-21drewz lin
This document provides an overview of the OWASP Broken Web Applications (OWASP BWA) project. It discusses the background and motivation for the project, describes the current status including what applications are included in the virtual machine, outlines future plans, and solicits feedback to help guide and expand the project. The goal of OWASP BWA is to provide a free, open-source virtual machine containing a variety of intentionally vulnerable web applications to aid in testing tools and techniques for finding and addressing security issues.
This document provides a summary of a presentation by Robert Hansen on the future of browser security. Hansen argues that while browser developers want to improve security and privacy, their companies' business models focused on advertising revenue prohibit them from doing so. He outlines various techniques used by advertisers and browser companies to track users against their preferences. Hansen advocates for technical controls that allow users to opt out of tracking through a "can not track" approach, rather than relying on ineffective "do not track" policies. He concludes by discussing WhiteHat Security's focus on privacy and their plans to add more security and privacy features to their Aviator browser.

(1) A study surveyed 600 software developers and found that most did not have a basic understanding of software security concepts, with 73% failing an initial survey and the average score being 59% before training. (2) However, after training, developers' understanding of key concepts increased, with some areas like cross-site scripting seeing a 20 percentage point gain. (3) The study concluded that targeted security training can improve developers' knowledge in the short-term, though retention of this knowledge may require refresher training over time.
Appsec 2013-krehel-ondrej-forensic-investigations-of-web-exploitationsdrewz lin
This document discusses forensic investigations of web exploitations. It presents a scenario where a web server in a DMZ zone was exploited but logs are unavailable, so network traffic must be analyzed. Wireshark will be used to analyze a PCAP file of recorded traffic to determine what happened and find any traces of commands or malware. The document also provides information on the costs of different types of cyber attacks, how to decode HTTP requests, and discusses tools that can be used for network forensics investigations like Wireshark, tcpdump, and Xplico.
Appsec2013 assurance tagging-robert martindrewz lin
The document discusses engineering software systems to be more secure against attacks. It notes that reducing a system's attack surface alone is not enough, as software and networks are too complex and it is impossible to know all vulnerabilities. It then discusses characteristics of advanced persistent threats, including that the initial attack may go unnoticed and adversaries cannot be fully kept out. Finally, it argues that taking a threat-driven perspective beyond just operational defense can help balance mitigation with detection and response.
The document summarizes a presentation on vulnerabilities found in SCADA systems between 2009-2013. It analyzed vulnerabilities by component, with the majority (66%) found in communication components like Modbus and DNP3 protocols. Examples of vulnerabilities are described for several devices. Real-world issues with SCADA systems are discussed like lack of authentication and patching. Recommendations are provided like auditing SCADA networks, implementing secure protocols and password policies, and keeping systems updated.
