This document summarizes a presentation on cross-site scripting (XSS) attacks and the XSS Alert tool. It defines XSS as enabling attackers to inject client-side scripts into web pages. It describes three types of XSS attacks and provides an example of a reflected XSS attack. It also discusses DOM security, how XSS Alert works to detect XSS vulnerabilities, and demonstrates an XSS attack on a Yahoo server.
Cross-Site Scripting (XSS) is a web security vulnerability that allows attackers to inject client-side scripts into web pages viewed by other users. There are three main types of XSS attacks: reflected XSS, stored XSS, and DOM-based XSS. XSS has been one of the top vulnerabilities on the OWASP Top Ten list for many years. While XSS attacks can compromise user sessions and steal sensitive data, developers can prevent XSS through proper input sanitization and output encoding. As web applications continue to grow in use, jobs in web application security and penetration testing are also expected to increase significantly in the coming years.

Phishing with Super Bait
Jeremiah Grossman, Founder and CTO, WhiteHat Security
The use of phishing/cross-site scripting (XSS) hybrid attacks for financial gain is spreading. ItÕs imperative that security professionals familiarize themselves with these new threats to protect their websites and confidential corporate information.
This isn't just another presentation about phishing scams or cross-site scripting. WeÕre all very familiar with each of those issues. Instead, weÕll discuss the potential impact when the two are combined to form new attack techniques. Phishers are beginning to exploit these techniques, creating new phishing attacks that are virtually impervious to conventional security measures. Secure sockets layer (SSL), blacklists, token-based authentication, browser same-origin policy, and monitoring / take-down services offer little protection. Even eyeballing the authenticity of a URL is unlikely to help.
By leveraging cross-site scripting, the next level of phishing scams will be launched not from look-alike web pages, but instead from legitimate websites! This presentation will demonstrate how these types of attacks are being achieved. We'll also demonstrate the cutting edge exploits that can effectively turn your browser into spyware with several lines of JavaScript. And, we'll give you the steps you need to take to protect your websites from these attacks.

Cross-Site Scripting (XSS) is a security vulnerability that allows malicious code to be injected into web pages viewed by other users. There are three main types of XSS attacks: non-persistent reflects the user's input back without filtering; persistent stores the input and displays it later to other users; and DOM-based exploits vulnerabilities in client-side scripts. XSS attacks are used to hijack user accounts, steal cookies, and conduct phishing scams. Developers can prevent XSS by sanitizing all user input, using encoding on untrusted fields, and keeping software updated.

Over the past year, clickjacking received extensive media coverage. News portals and security forums have been overloaded by posts claiming clickjacking to be the upcoming security threat.
In a clickjacking attack, a malicious page is constructed (or a benign page is hijacked) to trick the user into performing unintended clicks that are advantageous for the attacker, such as propagating a web worm, stealing confidential information or abusing of the user session.
This presentation introduces a novel solution we designed and implemented for an automated detection of clickjacking attacks on web-pages. The presentation details the architecture of our detection and testing system and it presents the results we obtained from the analysis of over a million "possibly malicious" Internet pages.

After my successful presentation "Testing iOS Apps without Jailbreak in 2018" it's time to change the side. This talk will cover the most important milestones in reaching secure iOS/macOS apps. I'm going to show you how to develop modern&secure iOS/macOS apps using new security features presented on WWDC2018. H4ckers will be satisfied as well since I'm going to talk about these steps from pentester's perspective. What's more - this presentation will include vulnerabilities that I found during my professional work and my vulnz found in real Apple's apps! (That I haven't disclosed yet!)
Cross-site scripting (XSS) allows malicious code injection into web applications. There are three types of XSS vulnerabilities: non-persistent, persistent, and DOM-based. To avoid XSS, developers should eliminate scripts, secure cookies, validate input, and filter/escape output. Proper coding practices can help prevent XSS attacks.

This document discusses cross-site scripting (XSS) attacks against mobile applications. It defines XSS as a type of injection where malicious scripts are injected into trusted websites. The document describes three types of XSS attacks - reflected XSS, stored XSS, and DOM-based XSS. It provides examples of each type of attack and how attackers are able to execute scripts on a victim's machine by injecting code. The document concludes with recommendations for preventing XSS attacks, including validating all input data, encoding all output data, and setting the proper character encoding.
Cross Site Scripting (XSS) is a vulnerability that allows malicious users to insert client-side code into web pages that is then executed by a user's browser. This code can steal cookies, access private information, perform actions on the user's behalf, and redirect them to malicious websites. XSS works by having the server display input containing malicious JavaScript from a request. There are different types of XSS attacks, including non-persistent, persistent, and DOM-based attacks. Prevention methods include validating, sanitizing, and escaping all user input on the server-side and client-side. Web vulnerability scanners like Burp Suite can help test for XSS and other vulnerabilities.
Cross site scripting (XSS) is a type of computer security vulnerability typically found in web applications, but in proposing defensive measures for cross site scripting the websites validate the user input and determine if they are vulnerable to cross site scripting. The major considerations are input validation and output sanitization.
There are lots of defense techniques introduced nowadays and even though the coding methods used by developers are evolving to counter attack cross site scripting techniques, still the security threat persist in many web applications for the following reasons:
• The complexity of implementing the codes or methods.
• Non-existence of input data validation and output sanitization in all input fields of the application.
• Lack of knowledge in identifying hidden XSS issues etc.
This proposed project report will briefly discuss what cross site scripting is and highlight the security features and defense techniques that can help against this widely versatile attack.

Asfws 2014 slides why .net needs ma-cs and other serial(-ization) tales_v2.0Cyber Security Alliance
The document summarizes a presentation about discovering a design issue in .NET's handling of view state fields without integrity protection. During a web application assessment in 2012, the presenter found that custom serialization of view state into an unprotected field could allow tampering by modifying the serialized object graph. This led to the realization that known .NET deserialization behaviors could be triggered remotely by manipulating the view state. A proof-of-concept exploited this by generating view state containing a FileInfo object that deleted a file on the server when deserialized. This uncovered a remote code execution vulnerability in some ASP.NET applications.

The document discusses detecting and defending against security vulnerabilities in Web 2.0 applications. It begins by outlining the top security issues in Web 1.0 vs Web 2.0 applications. Examples of vulnerabilities in Web 2.0 like cross-site scripting and injection flaws are provided. The document then demonstrates how to use security tools to detect vulnerabilities in a sample Web 2.0 application. Lastly, it discusses strategies for developing securely and testing applications, along with lessons learned from security findings.
The document discusses four main problems with the traditional approach to application security:
1. Security testing creates an asymmetric arms race between testers and attackers. Traditional end-of-cycle penetration tests only provide minimal security.
2. Applications often incorporate outsourced, open source, or third party code that may contain vulnerabilities. Dependency issues are rarely tested.
3. It is difficult to manage vulnerabilities at scale across a large number of applications and reports from different testers.
4. Security issues overwhelm developers with too much information, creating "white noise" and prioritizing compliance over risk. Contextualizing risk is important.
[CB16] Electron - Build cross platform desktop XSS, it’s easier than you thin...CODE BLUE
Electron is a framework to create the desktop application on Windows,OS X, Linux easily, and it has been used to develop the popular applications such as Atom Editor, Visual Studio Code, and Slack.
Although Electron includes Chromium and node.js and allow the web application developers to be able to develop the desktop application with accustomed methods, it contains a lot of security problems such as it allows arbitrary code execution if even one DOM-based XSS exist in the application. In fact, a lot of vulnerabilities which is able to load arbitrary code in applications made with Electron have been detected and reported.
In this talk, I focus on organize and understand the security problems which tend to occur on development using Electron.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
