Web Penetration Testing with Kali Linux

Chapter 2. Reconnaissance

The term Reconnaissance by definition comes from the military warfare strategy of exploring beyond the area occupied by friendly forces to gain information about the enemy for future analysis or attack. Reconnaissance of computer systems is similar in nature, meaning typically a Penetration Tester or hacker will attempt to learn as much as possible about a target's environment and system traits prior to launching an attack. This is also known as establishing a Footprint of a target. Reconnaissance is typically passive in nature and in many cases not illegal (however, we are not lawyers and cannot offer legal advice) to perform as long as you don't complete a three-way handshake with an unauthorized system.

Examples of Reconnaissance include anything from researching a target on public sources such as Google, monitoring employee activity to learn operation patterns, and scanning networks or systems to gather information, such as manufacture type, operating system...

Reconnaissance objectives


  • Target background: What is the focus of the target's business?

  • Target's associates: Who are the business partners, vendors, and customers?

  • Target's investment in security: Are security policies advertised? What is the potential investment security, and user security awareness?

  • Target's business and security policies: How does the business operate? Where are the potential weaknesses in operation?

  • Target's people: What type of people work there? How can they become your asset for the attack?

  • Define targets: What are the lowest hanging fruit targets? What should be avoided?

  • Target's network: How do the people and devices communicate on the network?

  • Target's defenses: What type of security is in place? Where is it located?

  • Target's technologies: What technologies are used for e-mail, network traffic, storing information, authentication, and so on? Are they vulnerable?

Kali Linux contains an extensive catalog of tools titled Information Gathering specified for Reconnaissance...

Initial research


Reconnaissance should begin with learning as much as possible about people and business associated with the target. Sun Tzu is credited with the phrase, "know your enemy" in the book, The Art of War. As a Penetration Tester, you need to know your target. If your target happens to be a website, you should look at all aspects of that website. It will give you a better understanding of how the site is maintained and run. Great Reconnaissance returns more possible vulnerabilities.

It is scary how much information is available on public sources. We have found the unimaginable, such as classified documents, passwords, vulnerability reports, undesirable photography, and access to security cameras. Many Penetration Testing project objectives start with leveraging information off public sources. Here are some starting points for gathering information from public sources.

Company website

There is a lot of valuable information that can be obtained from a target's website. Most corporate...

Summary


Reconnaissance is typically the most critical step in a Penetration Testing exercise and can be the most time consuming. Any actions taken against a target is customized around results from Reconnaissance previously performed. The more data known about a target equates to the less likely to trigger alarms, as well as better chance of identifying a way to compromise the target. It is recommended to look at this chapter as a prerequisite to the remaining chapters in this textbook.

In this chapter, we focused on various ways to gather information about a target. We showcased some popular free tools available on the Internet, as well as Information Gathering utilities available in Kali Linux. At this point, you should be ready to evaluate targets identified through Reconnaissance for possible exploitation.

The next chapter will focus on identifying and exploiting vulnerabilities in web applications and web servers.

Key benefits

  • Learn key reconnaissance concepts needed as a penetration tester
  • Attack and exploit key features, authentication, and sessions on web applications
  • Learn how to protect systems, write reports, and sell web penetration testing services

Description

Kali Linux is built for professional penetration testing and security auditing. It is the next-generation of BackTrack, the most popular open-source penetration toolkit in the world. Readers will learn how to think like real attackers, exploit systems, and expose vulnerabilities. Even though web applications are developed in a very secure environment and have an intrusion detection system and firewall in place to detect and prevent any malicious activity, open ports are a pre-requisite for conducting online business. These ports serve as an open door for attackers to attack these applications. As a result, penetration testing becomes essential to test the integrity of web-applications. Web Penetration Testing with Kali Linux is a hands-on guide that will give you step-by-step methods on finding vulnerabilities and exploiting web applications. "Web Penetration Testing with Kali Linux" looks at the aspects of web penetration testing from the mind of an attacker. It provides real-world, practical step-by-step instructions on how to perform web penetration testing exercises. You will learn how to use network reconnaissance to pick your targets and gather information. Then, you will use server-side attacks to expose vulnerabilities in web servers and their applications. Client attacks will exploit the way end users use web applications and their workstations. You will also learn how to use open source tools to write reports and get tips on how to sell penetration tests and look out for common pitfalls. On the completion of this book, you will have the skills needed to use Kali Linux for web penetration tests and expose vulnerabilities on web applications and clients that access them.

Who is this book for?

"Web Penetration Testing with Kali Linux" is ideal for anyone who is interested in learning how to become a penetration tester. It will also help the users who are new to Kali Linux and want to learn the features and differences in Kali versus Backtrack, and seasoned penetration testers who may need a refresher or reference on new tools and techniques. Basic familiarity with web-based programming languages such as PHP, JavaScript and MySQL will also prove helpful.

What you will learn

  • Perform vulnerability reconnaissance to gather information on your targets
  • Expose server vulnerabilities and take advantage of them to gain privileged access
  • Exploit client-based systems using web application protocols
  • Learn how to use SQL and cross-site scripting (XSS) attacks
  • Steal authentications through session hijacking techniques
  • Harden systems so other attackers do not exploit them easily
  • Generate reports for penetration testers
  • Learn tips and trade secrets from real world penetration testers
