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...

Installation and use of assetfinder

What is assetfinder ? Assetfinder is a subdomain discovery tool used in Kali Linux, focusing on finding related domains and subdomains for a target. It’s especially valued for its simplicity and efficiency in discovering assets associated with a domain, including subdomains and related domains. Assetfinder is particularly useful during the reconnaissance phase of penetration testing. Uses of Assetfinder in Kali Linux: Subdomain and Domain Discovery:  Assetfinder searches the web to find subdomains and related domains for a target domain. It aggregates data from various sources to provide a comprehensive list of assets. Combining Multiple Data Sources:  The tool integrates with numerous online services and databases, combining their results to give a broader view of the domain’s subdomains. This includes sources like crt.sh , certspotter , hackertarget , and others. Efficient and Quick Enumeration:  Assetfinder is known for its speed and efficiency. It quickly en...

OWASP Top 10 :Understanding Insecure Design

    What is insecure design? Insecure design means creating a system or application without thinking enough about security. These occur when security is not considered or prioritized during the design process, resulting in weaknesses that attackers can exploit. Types of Insecure Design: 1. Lack of Security Requirements:  Not including security requirements during the design phase. Example : Failing to specify that passwords should be stored using strong hashing algorithms. 2. Improper Data Validation:  Not verifying input data properly, Example : Not checking user inputs, allowing SQL injection attacks. 3. Weak Authentication and Authorization:  Inadequate mechanisms to verify user identity and access permissions. Example : Allowing access to sensitive data without proper user verification. 4. Lack of Logging and Monitoring : Not tracking system activities or security events. Example : Not logging failed login attempts, making it hard to detect brute-force attac...
