The document discusses an open redirect vulnerability found on the website nctsnet.org. An open redirect occurs when a website redirects a user's browser to a different URL, allowing an attacker to perform phishing attacks or distribute malware. The vulnerability on nctsnet.org was found in the pubdlcnt.php script, which did not validate or verify the redirect URL. An attacker could exploit this by crafting a malicious URL with the vulnerability and tricking users into clicking on the link. Open redirects abuse a site's trust and can be used to steal user information or credentials from a trusted domain.

Warningbird
This document describes WarningBird, a system for detecting suspicious URLs in Twitter streams. It uses URL redirection chains and tweet context to extract 11 features for classifying URLs. WarningBird crawls URLs to obtain redirection chains, then performs domain grouping, feature extraction and logistic regression classification. It achieved low false positive and negative rates on real Twitter data. WarningBird can process URLs quickly and detect suspicious accounts faster than Twitter's own systems.
How Twitter Usage Differs Between Humans and Company Accounts
The document analyzes differences between tweets from company accounts and personal accounts that one user follows. It finds that company accounts tweet much more often, with their tweets making up around 80% of tweets in the user's timeline even though they only represent around 46% of followed accounts. Company tweets also tend to receive more engagement in the form of favorites and retweets. In contrast, personal accounts interact with each other more by mentioning each other in tweets. Finally, company tweets are much more likely to include a URL, with around 95% doing so compared to a lower rate for personal accounts.
WARNINGBIRD: A NEAR REAL-TIME DETECTION SYSTEM FOR SUSPICIOUS URLS IN TWITTER...
This document describes WarningBird, a near real-time system for detecting suspicious URLs in Twitter streams. It analyzes correlated redirection chains of URLs, where attackers often reuse the same redirection routes. When WarningBird observes over w tweets, it groups URLs with the same domains and identifies frequently shared URLs. It extracts 11 features from redirection chains and uses supervised learning to flag tweets containing URLs from suspended accounts as suspicious. Compared to prior work, WarningBird enables real-time detection without account information and is resistant to fabrication through correlated URL analysis.
Security for javascript
An attacker can inject malicious scripts into a web page by exploiting security vulnerabilities in the browser environment. Once a foothold is gained, an attacker can access additional scripts from any server, make unauthorized requests to the vulnerable server, read data in the document, and send data to other servers. These attacks have been issues since Netscape 2 in 1995. Ultimately, JavaScript and the DOM need to be replaced with more secure alternatives to prevent cross-site scripting (XSS) attacks.

NTXISSACSC3 - How I hacked the Government and Got Away with It by Seven HatfieldNorth Texas Chapter of the ISSA
This document summarizes how the speaker hacked into a government training website and downloaded training videos without authentication. They describe their multiple unsuccessful attempts to report the vulnerability to the government via email, Twitter, and other means. The document suggests ways for the government to improve security, such as implementing a bug bounty program, conducting code audits, and having a vulnerability management program. It concludes that the government is currently unresponsive to security issues and that improvements are needed to address vulnerabilities.How I Hacked The Government And Got Away With It
In this presentation I spoke about how I found an information disclosure vulnerability within a Federal CyberSecurity training website, was able to report it responsibly, and the issues that came up as I attempted to do so.
Stateless Anti-Csrf
The document discusses stateless anti-CSRF techniques. It proposes a "triple submit" approach where the server sets an HTTP-only cookie with a random name and value, tells the client the value but not name, and the client submits both the name and value as request parameters. However, an attacker can still bypass this via cross-site scripting (XSS) by overflowing the browser's cookie jar and overwriting the HTTP-only cookie. The document demonstrates how to do this in different browsers.

Grey H@t - Cross-site Request Forgery
Cross-site scripting (XSS) and cross-site request forgery (XSRF) are two related web application vulnerabilities. XSS involves injecting malicious scripts into a web application to steal user data or perform actions on the user's behalf. XSRF tricks authenticated users into performing actions in a web application by submitting forged requests, since their browser will automatically include authentication cookies. While mitigations like validating HTTP referrers can help prevent XSRF, XSS can still be used to bypass these by scraping tokens or directly launching attacks from within compromised pages. Together, XSS and XSRF pose serious risks if not properly mitigated in web applications that handle sensitive data or perform sensitive actions.

This document discusses common security vulnerabilities in plugins and how to prevent them. It covers cross-site scripting (XSS) vulnerabilities, which can allow attackers to run JavaScript in a victim's browser. It also discusses cross-site request forgery (XSRF) vulnerabilities, which trick a victim into performing unwanted actions. The document provides guidance on using HTML encoding, generating secure random numbers, restricting file system access, and other techniques to prevent these vulnerabilities. It focuses on securing plugins used in Atlassian products like JIRA, Confluence and Bamboo.
CSRF Attack and Its Prevention technique in ASP.NET MVC
As the name suggests Cross Site Request Forgery Attack deals with the forgery of the trusted website of an authorized user with unwanted action. . These attacks have been called the “sleeping giant” of web-based vulnerabilities, because many sites on the Internet fail to protect against them and because they have been largely ignored by the web development and security communities . Our project aims at attacking the victim user by including a link or script in a page that accesses a site to which the user is known or is supposed to have been authenticated. Deep analysis of CSRF attack and finding the possibilities to mitigate the CSRF attack is our main focus and our objective on this project.
Web spoofing (1)
Web spoofing allows an attacker to create a fake version of the World Wide Web to trick victims. The attacker lures victims to their fake site, which looks identical to the real site. On the fake site, the attacker can observe any sensitive information entered by the victim. Current browsers are vulnerable to web spoofing attacks even on secure connections. Users should disable JavaScript, always check the URL bar, and be wary of any requests for sensitive information over email.

State of the Art Analysis Approach for Identification of the Malignant URLs
Malicious URLs have been universally used to ascend various cyber attacks including spamming, phishing and malware. Malware, short term for malicious software, is software which is developed to penetrate computers in a network without the user’s permission or notification. Existing methods typically detect malicious URLs of a single attack type. Hence such detection systems are failed to protect the users from various attacks. Malware spreading widely throughout the area of network as consequence of this it becomes predicament in distributed computer and network systems. Malicious links are the place of origin of all attacks which circulated all over the web. Hence malicious URLs should be detected for the prevention of users from these malware attacks. In this paper we described a novel approach which analyze all types of attacks by identifying malicious URLs and secure the web users from them. This technique prevents the users from malignant URLs before visiting them. Therefore efficiency of web security gets maintained. For such anatomization we developed an analyzer which identifies URLs and examine as malicious or benign. We also developed five processes which crawl for suspicious URLs. This approach will prevent the users from all types of attacks and increase efficiency of web crawling phase.

How not to make a hacker friendly application
Presentation on application security basics and some common vulnerabilities like XSS, SQL Injection, IDOR etc.
Web spoofing
Web spoofing allows an attacker to create a fake version of the entire web in order to trick victims. The attacker rewrites URLs on web pages so they link to the attacker's server instead of the real server. When the victim interacts with forms or links, their data and browsing is redirected to the attacker's server without their knowledge. While the victim sees secure connections, these are actually to the attacker's server, not the intended site. The attacker can then observe and modify any private information submitted by the victim.
Cookie surveillance
This document analyzes the privacy risks of mass surveillance by leveraging third-party HTTP tracking cookies. The researchers find that over 90% of a typical user's web visits can be linked together through shared unique cookies. Additionally, nearly half of popular websites leak a logged-in user's real identity in unencrypted traffic. This allows a passive network observer to cluster a user's entire browsing history and attach their real identity, violating expectations of privacy. The researchers discuss implications for targeted and mass surveillance online.
Unauthorized access, Men in the Middle (MITM)
In this type of attack, the attacker attempts to insert himself in the
middle of a communication for purposes of intercepting client’s data.
50063
Vulnerability Alert from Symantec reports that SilverStripe, an open source content management system, is prone to multiple cross-site scripting vulnerabilities in its admin URIs. This allows attackers to execute arbitrary script code in users' browsers to steal cookies or launch other attacks. The vulnerabilities are due to a failure to sanitize user input passed through various admin URIs. SilverStripe 2.4.5 is confirmed vulnerable.
Search Engine Poisoning
This report from Imperva’s Hacker Intelligence Initiative (HII), describes a Search Engine Poisoning (SEP) campaign from start to finish. SEP abuses the ranking algorithms of search engines to promote an attacker-controlled Web site that contains malware. Imperva’s Application Defense Center (ADC) has witnessed these types of automated attack campaigns, which cause search engines to return high-ranking Web pages infected with malicious code that references an attacker-controlled Web site.

SeanRobertsThesis
The document presents a hierarchical classification of web vulnerabilities organized into two main groups: general vulnerabilities that affect all web servers and service-specific vulnerabilities found in particular web server programs. General vulnerabilities are further divided into three sub-groups: feature abuse involving misuse of legitimate features, unvalidated input where user input is not checked before being processed, and improper design flaws. Validating user input and disabling vulnerable features can help eliminate certain vulnerability types like cross-site scripting resulting from unvalidated input or cross-site tracing from feature abuse. The hierarchy aims to help webmasters understand and address vulnerabilities by grouping similar issues.
Web Application Security
This document discusses web application security from the perspectives of web developers and attackers. It covers common issues web developers face, such as tight deadlines and lack of security standards. It also describes how attackers exploit vulnerabilities like injection attacks and XSS. Recent attacks are presented as examples, such as compromising a power grid operator's website through SQL injection. The document aims to raise awareness of web security challenges.
Pantallas escaneo Sitio Web
The document describes a vulnerability where the target server supports weak TLS/SSL ciphers and protocols, including SSLv2. This could allow attackers to decrypt encrypted communications and compromise sensitive data through man-in-the-middle attacks. Recommendations include disabling weak ciphers and protocols like SSLv2 to strengthen the security of encrypted connections.

A8 cross site request forgery (csrf) it 6873 presentation
The document discusses Cross Site Request Forgery (CSRF) attacks. It defines CSRF as an attack where unauthorized commands are transmitted from a user that a website trusts. The attack forces a logged-in user's browser to send requests, including session cookies, to a vulnerable website. This allows the attacker to generate requests the site thinks are from the user. The document outlines how CSRF works, example attacks, defenses for users and applications, and myths about CSRF. It recommends using unpredictable CSRF tokens or re-authentication to prevent CSRF vulnerabilities.

CSRF, or cross-site request forgery, occurs when a malicious website causes a user's browser to perform unintended actions on a website where the user is authenticated. Attackers can use CSRF to perform actions like transferring money from a user's bank account without their knowledge or consent. To prevent CSRF, websites should use POST requests instead of GET, assign random tokens for requests, and include CSRF protections in frameworks. Major sites have been vulnerable to CSRF in the past, so defenses against it are important.
Secure Form Processing and Protection - Devspace 2015
Joe Ferguson discusses common web application vulnerabilities like cross-site scripting (XSS) and cross-site request forgery (CSRF). He explains different types of XSS exploits and how CSRF works. To prevent these issues, he recommends sanitizing user input, using cryptographic nonces, and leveraging security features in frameworks like Angular, Zend, Symfony, Laravel and others. He also provides examples of widespread exploits on sites like Twitter, Facebook and MySpace to demonstrate the importance of secure form processing.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Must Know Postgres Extension for DBA and Developer during Migration
Must Know Postgres Extension for DBA and Developer during Migration
Paper nctsn
- 1. Open Redirect Vulnerability on NCTSN nctsnet.org has a link you can exploit it using open redirect vulnerability for a phishing. If you right click on mouse you can see this url: Taking the second part of the link, after pubdlcnt.php? =, you can include a malicious url and send to some user to perform phishing. http://www.nctsnet.org/sites/all/modules/pubdlcnt/pubdlcnt.php?file=
- 2. Analyzing the source code, we can observe that there is no validation or verification of the link to where the user will be redirected. But what are Open Redirect Vulnerabilities? An open redirect vulnerability occurs when a victim visits a particular URL for a given website and that website instructs the victim’s browser to visit a completely different URL, on a separate domain. When you visit the URL, the main page would receive a GET HTTP request and use the variable to parameter's value to determine where the visitor's browser should be redirected. After doing só, another page would return a 302 HTTP response, instructing the user's broswer to make a GET request to another page, the variable parameter's value. The Open Web Application Security Project (OWASP), which is a community dedicated to application security that curates a list of the most critical security flaws in web applications, has listed this vulnerability in ther 2014 Top Ten vulnerabilities list. Open redirects exploit the trust of a given domain, www.nctsnet.org, to lure victims to a malicious website. This can be used in phishing attack to trick users into believing theu are submitting information to the trusted site, when their valuable information is actually going to a malicious site. This also enables attackers to distribute malware from the malicious site or steal Oauth tokens.
- 3. Not all vulnerabilities are complex. This open redirect simply required changing the domain_name parameter to an external site, which would have resulted in a user being redirected off-site from NCTSNET. This type of vulnerability relies on an abuse of trust, where victims are tricked into visiting an attacker's site thinking they will be visiting a site they recognize. When you spot likely vulnerable parameters, be sure to test them out thoroughly and add special characters, like a period, if some part of the URL is hard-coded.
