Hands-On Bug Hunting for Penetration Testers

Choosing Your Hunting Ground

When you're deciding what bug bounty programs you'd like to participate in, it's nice to have a baseline of information about your options an offering company's report-submission process, submission success rate, the attack surface of the sites in question, and more. Luckily, that information is typically easy to find based on the type of company, its size, the nature of its reward program (third-party marketplace, in-house), and its public statements and documentation.

This chapter will cover how to evaluate marketplaces, programs, and companies and gauge their promise as productive engagements. It will also cover how to zero-in on the areas of web applications where you're most likely to find bugs. At the end of it, you'll know what programs to participate in, why, and how you can make the most of your target...

Technical Requirements

There are no software requirements associated with this section: you can explore all the resources listed here with just a standard web browser. In our case, that's Chrome (66.0.3359.139).

An Overview of Bug Bounty Communities – Where to Start Your Search

There are many different choices for bug bounty programs to participate in, but most boil down to two types: third-party marketplaces and company-sponsored programs.

Third-Party Marketplaces

Marketplaces are sites that match companies and researchers. They standardize the submission process, rules of engagement disclosure, and other documentation, while providing forums, teaching blogs, and other services to the community. Marketplaces are good sources of technical information and the metrics they typically collect related to things such as a company's response time and average payout can help you decide where to direct your efforts...

The Vulnerability of Web Applications – What You Should Target

Once you've narrowed down the program you're going to participate in or maybe you've skipped that and are just plowing through random sites, looking for easy pickings you can start evaluating individual applications for testing.

Doing so requires an understanding of each application's attack surface. As a quick refresher, Wikipedia sums it up succinctly:

The attack surface of a software environment is the sum of the different points (the attack vectors) where an unauthorized user (the attacker) can try to enter data to or extract data from an environment.

We'll get into actual Attack Surface Analysis in the next chapter, preparing for an engagement, but it helps to have a simple idea of it while evaluating different options.

Using that definition of an attack surface...

Evaluating Rules of Engagement – How to Protect Yourself

It's important before beginning an engagement to closely read the rules of engagement (sometimes also called a code of conduct) to understand the bounds of what is accepted within the program.

The Rules of Engagement lay out:

  • What techniques are allowed in the source of testing
  • What sites/domains/apps are open to pentesting
  • What parts (if any) of those apps are excluded from testing
  • What vulnerabilities merit the highest payouts
  • What vulnerabilities will not receive a payout at all
  • What credentials/account you should use as a security researcher (for a social network or something with authentication-restricted pages, companies will often offer pentesters a path to creating an account they can use to test user-restricted functionality)

The RoE are extremely important not just because they affect your ability...

Summary

This chapter discussed the criteria you can use to evaluate bug bounty marketplaces, programs, and individual pentesting targets. It covered different types of programs, their distinguishing features, and some of the basics of the bug bounties offered by Amazon, Facebook, Google, GitHub, and Microsoft, along with the learning resources and the general value of third-party bug bounty marketplaces such as Bugcrowd, HackerOne , Vulnerability Lab, BountyFactory, and Synack. It also went over the appeal of swag reward programs, the unique role of the Internet bug bounty Program, the nature of Coordinated Vulnerability Disclosure and the risks in using third-party brokers, along with how the Rules of Engagement/code of conduct for different bug bounty programs can differ. Finally, it covered setting up systems and processes within your own pentesting engagements to abide by...

Questions

  1. What are some differences between third-party marketplaces such as Bugcrowd and bug bounty programs offered by individual companies?
  2. Is it worth it to participate in programs that reward vulnerabilities with swag? Why or why not?
  3. What's a private bug bounty program?
  4. What are some resources you can use to find programs not covered in this chapter?
  5. What makes a site more or less attractive as a hunting ground for reward-eligible bugs?
  6. What is coordinated vulnerability disclosure?
  7. What steps can you take to minimize your legal liability during a pentesting session?

Description

Bug bounties have quickly become a critical part of the security economy. This book shows you how technical professionals with an interest in security can begin productively—and profitably—participating in bug bounty programs. You will learn about SQli, NoSQLi, XSS, XXE, and other forms of code injection. You’ll see how to create CSRF PoC HTML snippets, how to discover hidden content (and what to do with it once it’s found), and how to create the tools for automated pentesting work?ows. Then, you’ll format all of this information within the context of a bug report that will have the greatest chance of earning you cash. With detailed walkthroughs that cover discovering, testing, and reporting vulnerabilities, this book is ideal for aspiring security professionals. You should come away from this work with the skills you need to not only find the bugs you're looking for, but also the best bug bounty programs to participate in, and how to grow your skills moving forward in freelance security research.

Who is this book for?

This book is written for developers, hobbyists, pentesters, and anyone with an interest (and a little experience) in web application security.

What you will learn

  • Choose what bug bounty programs to engage in
  • Understand how to minimize your legal liability and hunt for bugs ethically
  • See how to take notes that will make compiling your submission report easier

No special information, a lot of linked resources and common terms for people that have expirience in basic bug bounty system. I understand the book is a entry level but I saw the book as a list of information not a methodology.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
