How to steal and modify data using Business Logic flaws - Insecure Direct Obj...Frans Rosén
This document discusses insecure direct object references (IDOR), which occur when a developer exposes references like file or database keys without access control. This allows attackers to access unauthorized data by manipulating the references. The document provides examples of IDOR vulnerabilities found in Twitter, Oculus, Square, Zapier, and WordPress. It emphasizes having a generic access control model, using user IDs instead of numeric IDs, and thoroughly reviewing code to prevent IDOR issues.
The Secret Life of a Bug Bounty Hunter – Frans Rosén @ Security Fest 2016Frans Rosén
Frans Rosén has reported hundreds of security issues using his big white hat since 2012. He have recieved the biggest bounty ever paid on HackerOne, and is one of the highest ranked bug bounty researchers of all time. He's been bug bounty hunting with an iPhone in Thailand, in a penthouse suite in Las Vegas and without even being present using automation. He'll share his stories about how to act when a company's CISO is screaming "SH******T F*CK" in a phone call 02:30 a Friday night, what to do when companies are sending him money without any reason and why Doctors without Borders are trying to hunt him down.

This document discusses penetration testing approaches from the past compared to today. It notes that in the past, penetration testing was easier because networks had fewer security controls like firewalls and patches. The document then provides tips and techniques for identifying security controls like load balancers, intrusion prevention systems, and web application firewalls that may be in place on modern networks. It also discusses ways to potentially bypass these controls like using encryption, proxies, or virtual private networks.

The first security technology bug bounty predated the Internet by over one hundred years: Alfred C Hobbs breaking an unbreakable lock at the Great Exhibition of 1851 for the princely sum of 200 Guineas. With the acceleration of technology adoption, unintended consequences, our adversaries, and the need to quickly understand how "unhackable" things really are, it's safe to say that things have escalated since then.
In 2021, there as many who benefit from engaging the good-faith hacker community as there are folks who find themselves lost in a mish-mash of term confusion, unclear expectations, and general reservations - in spite of the increasingly obvious truth that "it takes an army of allies to overcome an army of adversaries". This breakout is for both.
Casey John Ellis, the Founder, Chairman, and CTO of Bugcrowd, pioneer of the crowdsourced security as-a-service category, and co-founder of The Disclose.io Project will unpack the "family tree" of vulnerability disclosure, bug bounty, and crowdsourced security testing, frame up how we got here, and facilitate a discussion from the group about where it all goes next.
ACRNA Webinar #5: Cyber Security – The Unlikely RomanceCasey Ellis
When most folks hear the word “hacker” their reaction is one of fear, but those responsible for cybersecurity are increasingly understanding the role of the “digital locksmiths” amongst us. In this talk, Casey Ellis will unpack the unlikely romance between trusted, good-faith computer hackers, and the people who build and defend software infrastructure. He’ll share insights on how this feedback loop between builders and breakers has broken out of the early-adopter technology bubble to create a more resilient Internet for more traditionally conservative industries, including those where ICS/SCADA make up the core of their business.
There will also be plenty of time for Q&A, so get your questions ready!
#AusCERT2021 - Inside The Unlikely Romance Crowdsourced Security from a Finan...Casey Ellis
It has been 20 years since Rainforest Puppy released the RFPolicy responsible disclosure policy, 11 years since Google and Facebook brought the concept of bug bounty into the eye of the security industry, and 9 years since Bugcrowd pioneered the concept of inserting a platform in the process to facilitate conversations between builders and breakers in order to level the skill and resourcing playing field against our adversaries.
So, how’s it all going? Did it all turn out to be a “tech company” thing? What have the results, and the impact on cybersecurity defense been on more traditionally conservative industries, like financial services? What can the history of the relationship between helpful hackers and organizations tell us about what we’ll need for the future?
In this talk, Casey Ellis (Founder, Chairman, and CTO of Bugcrowd) will unpack some salient lessons after nearly 10 years building Bugcrowd.
Cross-Site Request Forgery (CSRF in short) is a kind of a web application vulnerability which allows malicious website to send unauthorized requests to a vulnerable website using active session of its authorized users
In simple words, it’s when an “evil” website posts a new status in your twitter account on your visit while the login session is active on twitter.
For security reasons the same origin policy in browsers restricts access for browser-side programming languages such as Javascript to access a remote content.
As the browsers configurations may be modified, the best way to protect web application against CSRF is to secure web application itself.

Applying principles of chaos engineering to serverless (O'Reilly Software Arc...Yan Cui
This document summarizes a talk on applying principles of chaos engineering to serverless applications. It discusses defining steady state, injecting realistic failures like latency and errors, and using controlled experiments to build confidence in a system's ability to withstand failures in production. Specifically for serverless, it addresses challenges like smaller units of deployment and many managed services, and demonstrates how to inject latency and errors at different points to test failure handling. The goal is learning from failures, not intentionally breaking systems, so containment is important.
The document discusses a meeting at Mozilla Paris on June 5th 2014 about application security. It begins with an introduction of Sebastien Gioria from OWASP who will be presenting. The agenda includes discussing the current state and future of application security, as well as an overview of the Open Web Application Security Project (OWASP) and major projects. It then discusses why application security is important given the prevalence of digital services and connected devices that can be hacked. Statistics are presented on the most common vulnerabilities and who the "winners" are in cyber attacks. An overview of OWASP is provided, including its mission, community involvement, resources and projects. The 10 most critical web application security risks or "OWASP Top 10
The document discusses various factors related to cybersecurity from multiple perspectives. It begins by looking at common human errors that contribute to cyber incidents, such as lack of communication, knowledge, teamwork, resources, and assertiveness. It then examines specific cybersecurity incidents and attributes the causes to human factors. The document advocates changing perspective to see problems as resulting from human rather than technical factors. It also discusses challenges around cloud computing and the need to consider both user and provider security controls and perspectives. Finally, it analyzes the "dirty dozen" human error types in more depth and provides countermeasures to address each type of error.
This document provides an overview of bug bounty hunting. It discusses:
- What bug bounty programs are and how they work
- A brief history of major bug bounty programs from the 1990s to present day
- Reasons to participate in bug bounty hunting like money, career opportunities, and enjoyment
- Popular bug bounty platforms and programs
- How to get started with the process of bug hunting
- Tips for writing bug reports that document the issue and steps to reproduce it

Puppet is an awesome tool to automate the configuration of your infrastructure, but it's also a potential attack vector. In this talk, we'll discuss some common patterns and changes you can make to harden your Puppet infrastructure, from the basic good practises such as data abstraction in modules, to some advanced customisation you might need in a high-security setup.
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.

Mobile Penetration Testing: Episode III - Attack of the CodeNowSecure
In the final installment of our mobile penetration testing trilogy, we dive deep to find security flaws in mobile apps by dissecting the code with reverse-engineering and code analysis.
This document contains over 100 links to RSS feeds from security organizations, vendors, and blogs that provide information on cyber threats, vulnerabilities, and security news. The feeds cover topics like malware, hacking, vulnerabilities, and security advisories from sources such as Cisco, Symantec, US-CERT, Sophos, Krebs on Security, and SANS.
Carsten Eiram has been involved with vulnerability databases (VDBs) for over 10 years. He reflects on areas related to vulnerabilities after a decade of experience working with VDBs. Some key metrics used to measure vulnerabilities, such as the number reported and severity scores, do not accurately capture a product's security state or level of risk. Other factors like whether issues are patched, the type of vulnerability, and potential chaining of issues need to be considered. Severity metrics also struggle with accurately scoring issues like sandbox bypasses that enable further attacks.
This document summarizes common web application vulnerabilities like SQL injection and cross-site scripting (XSS) for PHP applications. It provides examples of each vulnerability and discusses mitigation strategies like input sanitization, encoding output, and using security frameworks.

[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.

Common vulnerabilities included input validation issues, predictable URLs and parameters enabling CSRF, excessive privileges, and session management flaws. The author provides examples of compromising ClearOS and Websense gateways, and demonstrates OSRF through Proofpoint's email system. They conclude many techniques are older but there remains a knowledge gap between secure web and UI development.
Owasp Top 10 - Owasp Pune Chapter - January 2008abhijitapatil
The document discusses various cybersecurity topics including vulnerabilities, threats, attacks, and countermeasures. It provides an overview of the Open Web Application Security Project (OWASP) which focuses on improving application security. It also summarizes common web vulnerabilities like cross-site scripting (XSS), SQL injection, buffer overflows, and cross-site request forgery (CSRF). Recommendations are given to prevent these vulnerabilities.
XSS (cross-site scripting) is a common web vulnerability that allows attackers to inject client-side scripts. The document discusses various types of XSS attacks and defenses against them. It covers:
1) Reflected/transient XSS occurs when untrusted data in URL parameters is immediately displayed without sanitization. Stored/persistent XSS occurs when untrusted data is stored and later displayed. DOM-based XSS manipulates the DOM.
2) Defenses include HTML/URL encoding untrusted data before displaying it, validating all inputs, and using context-specific encoding for HTML elements, attributes, JavaScript, and URLs.
3) The OWASP Java Encoder Project and Microsoft Anti
The document discusses a meeting at Mozilla Paris on June 5th 2014 about application security. It introduces Sebastien Gioria from OWASP and provides an agenda covering the current state of application security, where it is hopefully going, and major OWASP projects that can be used. It then discusses why application security is important given the prevalence of digital services and connected devices, and common vulnerabilities found in websites.
Hacking 101 (Henallux, Owasp Top 10, WebGoat, Live Demo) Nitroxis Sprl
This document outlines an agenda for a training on web application hacking and security. It introduces common web application vulnerabilities like injection, broken authentication, cross-site scripting, and more. Examples of real-world hacking incidents are provided. The bulk of the training focuses on the OWASP Top 10 list of critical security risks, demonstrating each one through examples and a demo of the WebGoat vulnerability practice application. The training concludes with a discussion of additional topics and a question/answer period.
Make sure you’re defending against the most common web security issues and attacks with this useful overview of software development best-practices. We'll go over the most common attacks against web applications and present real world advice for defending yourself against these types of attacks.
1) The document discusses new hacking techniques that can exploit browsers and access internal corporate networks even when the browser has JavaScript disabled or restricted. These techniques bypass traditional perimeter security measures.
2) One technique uses CSS to steal a user's browsing history without JavaScript. Another obtains the user's internal IP address using a Java applet and then port scans the internal network to find vulnerabilities.
3) The author concludes that a user's browser, when visiting public websites, can potentially be silently hijacked to target and hack resources on the internal corporate network.
Security in the cloud protecting your cloud appsCenzic
The document discusses security best practices for cloud applications. It notes that 75% of cyber attacks target internet applications and over 400 new vulnerabilities are discovered each month. The top vulnerabilities include cross-site scripting, SQL injection, and insecure direct object references. The document provides examples of how these vulnerabilities can be exploited by hackers and recommends best practices like input validation, output encoding, secure authentication and session management to help protect applications.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
