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.

The document discusses various web security topics such as Google hacking, session hijacking, cross-site scripting, and SQL injection. It provides an agenda covering vulnerability types, mitigation strategies, and tools for testing each vulnerability. Recommendations are given for securing websites against common attacks discovered through search engines.

The document outlines 10 mistakes hackers want developers to make when building applications. The mistakes include: 1) Using dependencies with known vulnerabilities; 2) Unsanitized user input which can enable injection attacks; 3) Unsafe regex patterns that can allow denial of service attacks; 4) Failure to implement rate limiting and prevent abusive requests. The document provides examples and solutions for avoiding each mistake to help developers build more secure applications.

Bug bounty programs involve paying security researchers rewards for finding vulnerabilities in companies' products. To participate, researchers need to understand the target company's products and domains, know which companies offer bounties, and find bugs that are in scope like XSS, SQL injection, or authentication bypasses. Rewards can range from $100 to $20,000. Major companies like Google, Facebook, and Mozilla run bounty programs and have collectively paid over $1 million to researchers. Examples are shown of real bugs found and reported through bounty programs. The conclusion encourages reporting bugs to companies rather than selling vulnerabilities.

A web service platform for creating customized testing methodology based on the tech stack of the target, and how much time you have to test.

Hackers and developers are compared in the document. Hackers are described as skillful with deep technical understanding but often unsocial and focused on breaking systems. Developers are portrayed as true professionals who work with people to build applications and believe they can change the world. The document then provides examples of how hacking can look simple, such as cross-site scripting attacks on websites. It offers suggestions for prevention including input sanitization and access control. Later it discusses hacking in Node.js and risks of SQL and NoSQL injection. Finally it addresses how hacking and development skills could be applied for social good or security testing.

This paper presents a machine learning approach to identify malicious URLs. The researchers use URL lexical features, JavaScript source code features, and payload size as inputs to an SVM classifier. They achieve an accuracy of 0.81 and an F1 score of 0.74 when combining all feature types. Future work could involve testing on more malicious URLs and incorporating additional JavaScript and network features to improve detection of evolving attacks. The goal is to develop a real-time system for classifying URLs on mobile devices.

Different types of attacks Information security cross site scripting Denial of service attack phishing spoofing

Web security involves protecting information transmitted over the internet from attacks like viruses, worms, trojans, ransomware, and keyloggers. Users can help secure themselves by using antivirus software, avoiding phishing scams, and reporting spam. Larger attacks often involve botnets, which are networks of infected computers that can overwhelm websites and services with traffic through distributed denial of service attacks.

This document discusses hackers and software security. It provides examples of past hacks such as those on Sony Pictures and Citigroup. It outlines why software security is important when handling sensitive user information. The document discusses how hackers think and different types of hackers. It recommends following security principles like defense in depth, least privilege, and keeping security simple. It provides references for further reading on application security topics.

This document discusses phishing attacks and countermeasures. It begins by defining phishing as a type of email fraud where perpetrators send seemingly legitimate emails to collect personal and financial information. It then describes how phishing works, outlining the typical stages: creating fake websites, sending phishing emails with links to these sites, and hoping victims provide sensitive data or get infected with malware when they click the links. Specific phishing scams like spear phishing, whaling, pharming, spoofing, and vishing are also explained. The document concludes by listing warning signs of phishing websites and attacks.

The document discusses phishing attacks and how they work. It describes common phishing techniques like fraudulent links and forms in emails that steal personal information. It also explains how phishing kits are used to launch attacks and how money mules are recruited to launder stolen funds. Technical aspects like address bar spoofing and DNS hijacking are also covered, showing how phishers exploit systems and social engineering to target victims.

The document discusses trends in malware threats observed by McAfee Avert Labs. It notes a massive increase in the number of malware samples analyzed daily, with most being encrypted or packed to avoid detection. Banking trojans like ZeuS that perform man-in-the-middle attacks to steal login credentials are among the most prevalent threats. Criminal organizations have developed toolkits and markets to enable others to easily create and distribute their own malware.

Credential stuffing involves using breached username and password pairs from one site to attempt to log in to other sites where users may have reused passwords. It occurs in four main steps: 1) obtaining credentials from data breaches, 2) automating the login process without human interaction, 3) defeating any login defenses, and 4) distributing the process globally through botnets and cloud hosting. While two-factor authentication prevents account takeovers, credential stuffing can still reveal valid user accounts. Users and organizations are encouraged to take steps like using unique passwords, password managers, and two-factor authentication to help mitigate credential stuffing risks.

This All Things Open 2022 talk shows how to use current-gen WebAssembly to build complex applications out of components.

This document summarizes an analysis of an exploited NPM package called event-stream. It describes how an attacker gained control of the package and added malicious code that was downloaded by thousands of projects whenever their dependencies were updated. The malicious code stole cryptocurrency from wallets containing large amounts. It highlights the risks of supply chain attacks and emphasizes the importance of auditing dependencies, locking versions, and thinking carefully before adding new dependencies to avoid compromising entire projects and their users.

Jarrod Overson presented on a supply chain attack that occurred in 2018 through the compromise of the event-stream Node.js package. An unauthorized developer gained commit access and introduced malicious code through new dependencies that was then installed by millions of users. The malware harvested cryptocurrency private keys from the Copay wallet app. While the community responded quickly, such attacks demonstrate vulnerabilities in open source software supply chains and dependency management that will continue to be exploited if not properly addressed through changes to practices and tooling.

Shape Security analyzes 1.5 billion logins per week and protects 350 million user accounts. In 2016 alone, 1.6 billion credentials were leaked and sold or traded by criminals on dark web markets. Shape uses headless browsers like PhantomJS to automatically test leaked credentials on other sites, stopping over $1 billion in fraud losses in 2016. However, captchas intended to prevent automated attacks do not work and ruin the user experience.

Talk given at Mozilla's first View Source Conference in Portland, 2015. Details out the parallels between graphics and game developments compared to traditional web development.

This document discusses the dark side of web security, including automated threats from bots and attackers. It notes that traditional security like flossing is difficult to measure effectiveness. It outlines the OWASP top 10 vulnerabilities and automated threats attackers use. While captchas are meant to stop bots, services have made bypassing captchas easier. If a site has value like money, data, or content, there is value in exploiting it. Detection of attacks is difficult as attackers use many proxies and fingerprints to avoid detection. Patching is not enough, and spikes in traffic from many IPs could indicate an attack.

This was a talk given at HTML5DevConf SF in 2015. Ever wanted to write your own Browserify or Babel? Maybe have an idea for something new? This talk will get you started understanding how to use a JavaScript AST to transform and generate new code.

This document discusses ECMAScript 2015 (ES2015), also known as ES6. It provides examples of new ES2015 features like arrow functions, template literals, classes, and modules. It also discusses how to set up a development environment to use ES2015, including transpiling code to ES5 using Babel, linting with Eslint, testing with Mocha, and generating coverage reports with Istanbul. The document emphasizes that while ES2015 is fun to explore, proper tooling like linting and testing is needed for serious development. It concludes by noting ES2015 marks a transition and thanks the audience.

The document discusses achieving maintainability in code through examining code quality with linters, generating visual reports on metrics like complexity and coverage, and automating processes like builds, linting, and testing through tools like Grunt and Gulp. It emphasizes setting limits on metrics like complexity, enforcing code style through automation, and treating documentation as important as code.

1) The document discusses achieving maintainability in code through analysis, automation, and enforcement of standards. 2) It recommends setting up linting, code coverage, and other analysis tools to examine code quality and automatically enforcing code style through build processes. 3) The key is to automate as many processes as possible like testing, linting, and documentation to make the code easy to work with and prevent issues from being introduced.

Slides for the keynote given at QCon Sao Paulo 2014. Talk goes into the problems scaling Riot and how we've tried to solve them as well as what we've learned from the web and what lies in store next.

This document discusses managing complexity in JavaScript projects. It addresses coming to terms with the challenges of dynamic languages being messy, having an immature tooling ecosystem, and rapid evolution. It emphasizes respecting code style conventions, enforcing linting rules, documenting code, and using metrics like cyclomatic complexity to reduce testing difficulty. The overall message is that perseverance is needed to tame JavaScript's complexity through automation, visualization, honesty and acceptance of its challenges and opportunities.

The document discusses web components, which include HTML templates, custom elements, shadow DOM, and HTML imports. Web components allow the creation of reusable custom elements with their own styles and DOM structure. They provide encapsulation and help avoid issues with global namespaces. While browser support is still emerging for some features, polyfills exist and frameworks like Polymer make web components accessible today. Web components represent an important evolution of the web that will improve how code is structured and shared.
