This lab’s two-factor authentication is vulnerable to brute-forcing. The PortSwigger Web Security Academy formulates the task as follows: The test task is available on the PortSwigger Web Security Academy educational portal it’s perfectly suited for my purposes because you have to perform hundreds of repetitive multistep actions. By the way, you can gain a considerable reward on Bug Bounty for exploiting such vulnerabilities. Today, such passwords are used virtually everywhere. To test the above methods, I will use a very typical problem: brute-forcing a four-digit one-time password.
Let’s discuss these approaches (and their advantages and limitations) in more detail. Turbo Intruder extension developed by the creators of Burp Suite.The tool provides several ways to automate your actions: In addition, to be able to send and process requests at a high speed and implement parallel execution, you need to know the correct stacks that neither slow down the parallel execution nor perform unnecessary actions that complicate the execution.īurp Suite was developed for lazy hackers unwilling to use programming languages for implementation of such tasks. Scripting languages are perfectly suited for automated multistep attacks, but in many situations, it’s not reasonable to spend an extra hour writing and debugging code when a ready-made solution requiring minimum configuring is available. Which one to choose if you need, for instance, to make five requests over HTTP a thousand times in a row, while maintaining the same session? My choice is Burp Suite, and in this article, I will explain why. There are plenty of tools designed for this purpose. brute-force a password or the second authentication factor, repeatedly use the same resource, etc.). When you attack a web app, you sometimes have to perform a certain sequence of actions multiple times (e.g.
