Intruder Tab In Burp Suite

What is the intruder tab?

The Intruder tab in Burp Suite is a powerful tool for automating customized attacks against web applications. It allows you to perform various tasks such as brute force attacks, parameter fuzzing, and testing for vulnerabilities like SQL injection, cross-site scripting (XSS), and more.



Key Features:

1. Target and Position: Specify the target URL and define the positions within the request where payloads will be inserted. These positions are marked with the symbols §.

2. Attack Types: Choose from different attack types such as Sniper, Battering ram, Pitchfork, and Cluster bomb, each with unique ways to combine payloads and positions:

  • Sniper: Uses one set of payloads and iterates through them, attacking one position at a time.

  • Battering Ram: Uses one set of payloads and inserts the same payload into all positions simultaneously.

  • Pitchfork: Uses multiple payload sets and iterates through them in parallel, inserting payloads into corresponding positions.

  • Cluster Bomb: Uses multiple payload sets and iterates through every possible combination, inserting them into the positions.

3. Payloads:

  • Payload Sets: Configure one or more sets of payloads. Each set can be customized with different types of payloads, including simple lists, numbers, dates, and custom payloads.

  • Payload Options: Customize the payloads using transformations, encodings, and other options.

4. Options:

  • Attack Options: Configure various attack options such as the number of threads, request throttling, and handling of HTTP responses.

  • Grep - Match and Extract: Specify patterns to match or extract data from responses, which are useful for analyzing the results of the attack.

  • Redirections: Handle HTTP redirections automatically during the attack.

  • Handling of Cookies and Sessions: Configure session handling rules to maintain or regenerate sessions during the attack.

Practical Applications:

1. Brute Force Login: Identify valid username and password combinations for a login form.

2.SQL Injection Testing: Test for SQL injection vulnerabilities by inserting payloads into parameters.

3. Cross-Site Scripting (XSS) Testing: Identify XSS vulnerabilities by injecting malicious scripts into input fields.

4. Directory and File Enumeration: Discover hidden directories and files on the web server.

5. Parameter Fuzzing: Identify unexpected behavior by sending a variety of payloads to different parameters.

6. Session ID Analysis: Assess the predictability and strength of session IDs by generating and analyzing multiple session tokens.

7. HTTP Header Injection Testing: Test for vulnerabilities by injecting payloads into HTTP headers.

8. CSRF Token Analysis: Evaluate the strength and predictability of CSRF tokens.

9. Hidden Parameter Discovery: Discover hidden parameters that are not exposed in the normal application flow.

How to use the intruder tab:



  • In Burp Suite you find the intruder tab. it looks like that.




  • From the intercept tab, you can send the request to the intruder tab. you can right-click and click on send to intruder or press Ctrl+I for send request to intruder tab.



  • Then open the intruder tab. you can see the request that you sent from the intercept.



  • From intruders, you can perform 4 types of attacks. which are Sniper, Battering ram, Pitchfork, and Cluster bomb. 



  • Select the text that u want to target. for example, i take one OGPC. and then click on the add button to add it to the position. 



  • After clicking the add button you can see the added position like this.



  • Then click on the payloads. then you see the number of payloads that u added. select one by one.



  • You can set any payload like any list, numbers, and more.



  • If you have only a few then you can also add like this. For example, I add some text in the payload list. then click on the start attack button to start the attack.




  • After clicking that you see the output like this. here you have all the responses for the payload you use in the attack.



  • you can also click on the request that you want. after the click, you see the request at the bottom. 



  • you can also see the response here.

OWASP Top 10 : Understanding Broken Access Control

What is broken access control? Broken access control is a security issue where users can access data or perform actions that they shouldn't be allowed to. This happens when the system fails to properly enforce rules about what users can and cannot do. Types of access controls :  1 . Vertical privilege escalation:  Vertical privilege escalation happens when a normal user gains access to functionalities reserved for higher-privileged users. Example:  A normal user can change the policies of the company.  2. Horizontal privilege escalation:  Horizontal privilege escalation allows a user to switch their access to another user's account, essentially impersonating them. Example:  A normal user can switch their account to admin.  3 . Insecure direct object reference ( IDOR):  IDOR occurs when an application exposes a reference to an internal implementation object, such as a file, directory, or database key. Example:  Suppose...

Intruder - Battering Ram Attack

Purpose:  The Battering Ram attack type is used when you need to insert the same payload into multiple positions within the same request. This can be useful in scenarios where multiple fields might share the same value or where you want to test how the application handles identical inputs across different parameters. How It Works: Multiple Position Synchronization:  In a Battering Ram attack, the same payload is simultaneously inserted into all the designated positions within the request. Synchronized Input Testing:  This type of attack is beneficial for testing inputs that are expected to be the same or related across different fields. Steps: 1.Capture the Request: Use Burp Suite’s Proxy tab to intercept the login request. For example, the intercepted HTTP POST request might look like this :                                       ...

Intruder - Pitchfork Attack

Purpose:  The Pitchfork attack type allows you to test multiple parameters with different payloads simultaneously. It’s ideal for scenarios where you want to test how different combinations of inputs interact with each other. How It Works: Parallel Payload Insertion:  In a Pitchfork attack, Burp Suite inserts different payloads from multiple lists into multiple positions. Each position gets its unique payload. Combinatorial Testing:  This method is effective when you suspect that specific combinations of inputs might trigger unique responses or vulnerabilities. Steps: 1.Capture the Request: Use Burp Suite’s Proxy tab to intercept the login request. For example, the intercepted HTTP POST request might look like this :                                        POST /example?p1=p1val&p2=p2val HTTP/1.0      ...
