Hands-On Application Penetration Testing with Burp Suite

By: Carlos A. Lozano, Dhruv Shah, Riyaz Ahemed Walikar

Overview of this book

Burp suite is a set of graphic tools focused towards penetration testing of web applications. Burp suite is widely used for web penetration testing by many security professionals for performing different web-level security tasks. The book starts by setting up the environment to begin an application penetration test. You will be able to configure the client and apply target whitelisting. You will also learn to setup and configure Android and IOS devices to work with Burp Suite. The book will explain how various features of Burp Suite can be used to detect various vulnerabilities as part of an application penetration test. Once detection is completed and the vulnerability is confirmed, you will be able to exploit a detected vulnerability using Burp Suite. The book will also covers advanced concepts like writing extensions and macros for Burp suite. Finally, you will discover various steps that are taken to identify the target, discover weaknesses in the authentication mechanism, and finally break the authentication implementation to gain access to the administrative console of the application. By the end of this book, you will be able to effectively perform end-to-end penetration testing with Burp Suite.

Exploiting crypto vulnerabilities


More than exploiting vulnerabilities related to cryptography, Burp Suite allows users to perform analysis to detect weak algorithms.

To perform this analysis, we need to create a capture. This capture is just a navigation where we log in and log out from an application in order to create sessions, tokens, and IDs. The idea is to create the biggest capture that we can in order to have a sample.

 

 

After creating the capture, use the normal history in Burp Suite, go to the Sequencer tool, and click on Analyze now, as demonstrated in the following screenshot:

Here, you can see the final analysis, as follows:

The Final Analysis

Now, you can determine whether the algorithm used is weak or not based on the entropy, the charset, and the probability.
