Objective: Launch Burp Suite with a Specific Project File

This command starts Burp Suite and instructs it to load an existing project file or create a new one if it doesn't exist.

Command:

Bash

burpsuite --project-file=/home/kali/projects/client-a.burp

Command Breakdown:

Ethical Context & Use-Case: In a professional penetration testing engagement, maintaining separate project files for each client is a non-negotiable requirement for organization and data segregation. This command allows you to load the entire state of a previous session, including the target scope, sitemap, proxy history, and tool configurations, ensuring a seamless continuation of your assessment.

[VISUAL OUTPUT: The Burp Suite splash screen appears, followed by the main dashboard. The project file /home/kali/projects/client-a.burp is loaded, and the window title reflects the project name.]

Objective: Start Burp Suite with a Custom Configuration File

This command launches Burp Suite and applies a pre-saved configuration file, which can contain settings for the proxy, scanner, user interface, and more.

Command:

Bash

burpsuite --config-file=/home/kali/configs/api_testing_config.json

Command Breakdown:

Ethical Context & Use-Case: Efficiency is key during an assessment. Penetration testers often create different configuration files for various testing scenarios (e.g., testing a REST API vs. a standard web application). This command allows you to instantly load a tailored testing environment, saving significant time on manual reconfiguration and ensuring consistency across tests.

[VISUAL OUTPUT: Burp Suite launches. A dialog box confirms that the configuration from api_testing_config.json has been loaded, potentially altering settings like Proxy listeners or live scanning options visible in the UI.]

Objective: Launch Burp Suite with Extensions Disabled

This command starts Burp Suite without loading any installed extensions (BApps).

Command:

Bash

burpsuite --disable-extensions

Command Breakdown:

Ethical Context & Use-Case: Occasionally, an installed extension may cause instability, performance issues, or conflicts with the target application. This command is a critical troubleshooting step, allowing you to launch a "clean" instance of Burp Suite to determine if an extension is the source of a problem. It ensures the core tool's reliability when you need it most.

[VISUAL OUTPUT: Burp Suite launches normally, but the Extender tab shows an empty list of installed extensions, and no extension-related output appears in the console or event log.]


Tactical Operations: Core Modules & Use-Cases


Burp Suite's power comes from its integrated set of tools. The following "examples" are structured as tasks performed within the GUI, representing the core workflow of a web application penetration tester.


Burp Proxy: The Interception Engine


The Proxy is the heart of Burp Suite, sitting between your browser and the target application, allowing you to inspect and manipulate all traffic.

Objective: Intercept and Modify an HTTP GET Request

Action/Steps:

  1. Launch Burp Suite and configure your browser to use the Burp Proxy listener (typically 127.0.0.1:8080).

  2. In the Burp Suite UI, navigate to the Proxy > Intercept tab.

  3. Ensure the "Intercept is on" button is active.

  4. In your browser, navigate to a page on your target application (e.g., http://example.com/profile?id=123).

  5. The request will be captured and displayed in the Intercept tab.

  6. Modify the id parameter value from 123 to 124.

  7. Click the "Forward" button to send the modified request to the server.

Configuration Breakdown:

Ethical Context & Use-Case: This is the most fundamental technique in web application testing. By intercepting a request, a tester can manipulate parameters to test for vulnerabilities like Insecure Direct Object References (IDOR). For instance, changing id=123 to id=124 could test whether you can view another user's profile, which would be a critical security flaw. This must only be done on applications you are authorized to test.

[VISUAL OUTPUT: The Proxy > Intercept tab shows the raw HTTP GET request. The id=123 parameter is highlighted, showing the user has edited it to id=124. The response from the server for user 124's profile is then visible in the HTTP history.]

Objective: Drop a Specific Request

Action/Steps:

  1. With interception enabled in the Proxy > Intercept tab, wait for a request to be captured.

  2. Analyze the request. If it is irrelevant to your testing (e.g., a request to a third-party analytics service), click the "Drop" button.

Configuration Breakdown:

Ethical Context & Use-Case: During an assessment, a web application generates a lot of "noise"—requests to trackers, ad networks, or content delivery networks that are not in scope. The "Drop" function allows a tester to efficiently discard this traffic, keeping the focus and the proxy history clean and relevant to the target application's security.

[VISUAL OUTPUT: An intercepted request to google-analytics.com is displayed in the Intercept tab. After clicking "Drop," the request disappears, and the browser waiting for the request eventually times out or moves on.]

Objective: Add a Target to Scope

Action/Steps:

  1. Navigate to the Proxy > HTTP history tab.

  2. Browse the target application to populate the history.

  3. Right-click on a request made to the target domain (e.g., https://authorized-target.com).

  4. In the context menu, select "Add to scope".

  5. A dialog will ask if you want to stop sending out-of-scope items to the history. Select "Yes".

Configuration Breakdown:

Ethical Context & Use-Case: Defining a clear scope is the most important first step in any professional penetration test. It ensures you are only testing assets you have explicit permission to assess. Adding a target to scope in Burp focuses the tool's powerful features, like the scanner and sitemap, only on the authorized targets, preventing accidental or illegal testing of out-of-scope systems.

[VISUAL OUTPUT: The Target > Scope tab now shows https://authorized-target.com as a defined target. The Proxy > HTTP history tab now visually grays out or hides requests to other domains.]

Objective: Create a Proxy Match and Replace Rule

Action/Steps:

  1. Navigate to the Proxy > Options tab.

  2. Scroll down to the "Match and Replace" section and click "Add".

  3. Create a new rule:

  4. Ensure the checkbox next to the rule is enabled.

Configuration Breakdown:

Ethical Context & Use-Case: During an authorized penetration test, it's often professional courtesy—and sometimes a requirement—to use a custom User-Agent string. This allows system administrators and security teams on the client's side to easily identify traffic coming from the testing team in their logs and differentiate it from real user traffic or a genuine attack.

[VISUAL OUTPUT: The "Match and Replace" table in the Proxy Options now lists the new User-Agent rule. In the Proxy HTTP history, every subsequent outgoing request now shows the User-Agent: HACKR-Testing-Bot/1.0 header.]


Burp Repeater: Manual Request Crafting


Repeater allows you to take any request, modify it endlessly, and resend it to observe how the server responds. It is the primary tool for manual vulnerability discovery.

Objective: Test for SQL Injection using Repeater

Action/Steps:

  1. In the Proxy > HTTP history, find a request with a parameter, such as GET /products?id=5.

  2. Right-click the request and select "Send to Repeater".

  3. Navigate to the Repeater tab. The request will be pre-loaded.

  4. Click "Send" to get a baseline response.

  5. In the request panel, modify the id parameter to id=5'.

  6. Click "Send" again.

  7. Observe the response panel for changes, such as a database error message, a different HTTP status code, or a change in content length.

Configuration Breakdown:

Ethical Context & Use-Case: Repeater is the surgeon's scalpel for vulnerability testing. This specific use-case demonstrates a basic manual check for SQL Injection. By sending a single quote ('), we attempt to break the SQL query on the backend. If the application returns a database error, it's a strong indicator of a vulnerability. This controlled, single-request method is perfect for careful, non-disruptive probing of an authorized target.

[VISUAL OUTPUT: The Repeater UI is shown. The left panel contains the request with id=5'. The right panel displays the server's response, which now includes a verbose SQL error message like "You have an error in your SQL syntax..."]

Objective: Test for Path Traversal

Action/Steps:

  1. Find a request in your proxy history that appears to be loading a file, e.g., GET /viewfile?name=report.pdf.

  2. Send this request to Repeater.

  3. In the Repeater request panel, modify the name parameter to test for path traversal. Try payloads like:

  4. Click "Send" after each modification and analyze the response.

Configuration Breakdown:

Ethical Context & Use-Case: Path Traversal vulnerabilities allow an attacker to read arbitrary files from the server. By using Repeater to send controlled payloads like ../../etc/passwd, a penetration tester can safely determine if the application is vulnerable without using automated scanners, which might be too noisy. A successful test would return the contents of the /etc/passwd file, a critical finding in any assessment.

[VISUAL OUTPUT: The Repeater's response panel shows the raw text content of a typical /etc/passwd file, starting with root:x:0:0:root:/root:/bin/bash.]


Burp Intruder: Automated Fuzzing


Intruder is a powerful tool for automating custom attacks. It can iterate through lists of payloads, sending a request for each one and logging the results.

Objective: Fuzz for Usernames (Enumeration)

Action/Steps:

  1. Capture a failed login request (e.g., POST to /login) and send it to Intruder.

  2. Go to the Intruder > Positions tab. The request will be displayed.

  3. Click "Clear §" to remove default payload markers.

  4. Highlight the value of the username parameter (e.g., user=test) and click "Add §".

  5. Go to the Attack type dropdown and select Sniper.

  6. Go to the Payloads tab. Under "Payload Options [Simple list]", click "Add" and enter a list of potential usernames (e.g., admin, administrator, root, user).

  7. Click the "Start attack" button.

Configuration Breakdown:

Ethical Context & Use-Case: During an authorized test, an ethical hacker may need to determine valid usernames on an application. The login page often gives different responses for "invalid username" versus "invalid password." By automating this check with Intruder, a tester can efficiently identify valid accounts by looking for subtle differences in the server's responses (e.g., response length or specific error messages), which is a valuable piece of information for subsequent password attacks.

[VISUAL OUTPUT: A new Intruder attack window opens, showing a table of results. Each row represents a request. The "Payload" column shows admin, administrator, etc. The "Length" column for the admin payload is different from the others, indicating a different server response and thus a likely valid username.]

Objective: Brute-Force a 4-Digit PIN

Action/Steps:

  1. Capture a request to a PIN validation endpoint (e.g., POST /validate_pin) and send it to Intruder.

  2. Go to the Intruder > Positions tab and mark the PIN parameter (e.g., pin=1111) as the payload position.

  3. Go to the Payloads tab.

  4. Set the "Payload type" to Numbers.

  5. Configure the number range:

  6. Configure number formatting options:

  7. Click "Start attack".

Configuration Breakdown:

Ethical Context & Use-Case: Many applications use weak PINs for authentication or session validation. This Intruder configuration allows a tester to perform a comprehensive brute-force attack against a 4-digit PIN endpoint within an authorized testing scope. The results can be sorted by response length or HTTP status to quickly identify the correct PIN, demonstrating a critical authentication vulnerability to the client.

[VISUAL OUTPUT: The Intruder attack window displays results for payloads 0000 through 9999. One row, for payload 1337, shows a 302 Found status code and a different response length, while all others show a 200 OK with a "PIN Invalid" message.]


Burp Decoder & Comparer


Decoder is a utility for transforming data, while Comparer is a visual diff tool for comparing requests or responses.

Objective: Decode a Base64 Encoded Parameter

Action/Steps:

  1. In your Proxy history, find a request that contains what appears to be a Base64 encoded string (e.g., a parameter like data=eyJuYW1lIjoiSm9obiJ9).

  2. Highlight the encoded string eyJuYW1lIjoiSm9obiJ9.

  3. Right-click and select "Send to Decoder".

  4. Navigate to the Decoder tab. The string will be in the input field.

  5. In the "Decode as" menu on the right, select Base64. The decoded text will appear in the output field.

Configuration Breakdown:

Ethical Context & Use-Case: Developers sometimes use simple encoding like Base64 to obfuscate data, believing it provides security. It does not. A penetration tester must be able to quickly decode this data to understand what the application is transmitting. In this case, decoding the string reveals a JSON object ({"name":"John"}), which can then be manipulated and re-encoded to test for other vulnerabilities like privilege escalation or injection.

[VISUAL OUTPUT: The Decoder tab shows eyJuYW1lIjoiSm9obiJ9 in the top box. In the box below, after selecting "Decode as: Base64", the text {"name":"John"} is displayed.]

Objective: Compare Two Responses in Comparer

Action/Steps:

  1. From your Proxy history or Repeater, find two responses you want to compare. For example, the response for a valid user and an invalid user.

  2. Right-click the first response and select "Send to Comparer".

  3. Right-click the second response and also select "Send to Comparer".

  4. Navigate to the Comparer tab. The two items will be loaded.

  5. Select "Words" or "Bytes" at the bottom to perform the comparison.

Configuration Breakdown:

Ethical Context & Use-Case: Comparer is essential for spotting subtle differences that indicate a vulnerability. For example, when testing for a blind SQL injection, a successful query might result in only a one-word change deep within a large HTML response. Manually finding this change is nearly impossible. Comparer automates this process, visually highlighting the exact differences and allowing the tester to confirm the vulnerability with certainty.

[VISUAL OUTPUT: The Comparer window shows two large HTML responses side-by-side. The left response contains the text "Welcome back, user!", while the right one contains "Welcome back, admin!". The words "user" and "admin" are highlighted in different colors to show the modification.]


Strategic Campaigns: Advanced Command Chains


While Burp Suite is primarily a GUI tool, its output can be saved and processed by powerful command-line utilities to extract and analyze data efficiently.

Objective: Extract All Unique Endpoints from Proxy History using grep and sort

Action/Steps:

  1. In Burp Suite, go to the Proxy > HTTP history tab.

  2. Select all requests for the in-scope target.

  3. Right-click and choose "Save items". Save the file as history.xml.

  4. In a terminal, run the following command to parse the XML, extract URLs, clean them, and find unique endpoints.

Command:

Bash

cat history.xml | grep -oP '<url><!\[CDATA\[.*?\]\]></url>' | sed -e 's/<\/\?url><!\[CDATA\[//g' -e 's/\]\]>//g' | cut -d '?' -f 1 | sort -u

Command Breakdown:

Ethical Context & Use-Case: During the reconnaissance phase of a test, understanding the complete attack surface is critical. While Burp's Target sitemap is excellent, sometimes a simple, clean list of all unique endpoints is required for scripting or reporting. This command chain provides a rapid way to process a large Burp history file and generate such a list, which can then be fed into other tools or used for manual analysis.

--> Expected Output:

https://authorized-target.com/
https://authorized-target.com/about
https://authorized-target.com/api/login
https://authorized-target.com/api/users
https://authorized-target.com/contact
https://authorized-target.com/dashboard
https://authorized-target.com/login
https://authorized-target.com/profile
https://authorized-target.com/static/main.js

Objective: Find Interesting Responses from Intruder Results using awk

Action/Steps:

  1. In a Burp Intruder attack window, select all results.

  2. Go to the "Save" menu and choose "Results table".

  3. Save the results as a comma-delimited text file named intruder_results.csv.

  4. In a terminal, use awk to parse the CSV and print requests that resulted in a specific response length (e.g., a length that indicates a successful login).

Command:

Bash

awk -F',' '$3 == 302 { print "Found interesting payload:", $2 }' intruder_results.csv

Command Breakdown:

Ethical Context & Use-Case: An Intruder attack can generate thousands of results. Manually sifting through them is inefficient and prone to error. This command automates the analysis. For example, in a password brute-force attack, a successful attempt might result in a 302 Found (redirect) status code, while all failures result in 200 OK. This awk one-liner instantly filters a massive result set to pinpoint the exact payload that succeeded.

--> Expected Output:

Found interesting payload: P@ssword123
Found interesting payload: Qwerty!

Objective: Search All Responses in a Saved Project for a Specific Error String

Action/Steps:

  1. Save your Burp project as client-a.burp. Note that Burp project files are archives.

  2. Unzip the project file into a directory to access the raw request/response data.

  3. Use grep recursively to search all the raw response files for a specific string that might indicate a vulnerability (e.g., "SQL syntax").

Command:

Bash

unzip client-a.burp -d client-a_files && grep -r "SQL syntax" client-a_files/

Command Breakdown:

Ethical Context & Use-Case: Sometimes after a long testing session, you might want to perform a global search for specific keywords or error messages across every single response received. This could be to find all occurrences of a specific error code, an email address, or, as in this example, a string indicating a potential SQL injection that was missed during initial analysis. This technique allows for a thorough post-assessment data mining exercise on an authorized project file.

--> Expected Output:

client-a_files/13/2.resp:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
client-a_files/45/8.resp:Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /var/www/html/users.php on line 88. SQL syntax error.


AI Augmentation: Integrating with Artificial Intelligence


Leveraging AI, particularly through scripting, can significantly enhance the analysis of data generated by Burp Suite, turning raw output into actionable intelligence.

Objective: Visualize Intruder Attack Results with Python to Find Anomalies

This script uses Python with pandas and matplotlib to parse exported Intruder results and create a scatter plot of response lengths, making it easy to spot outliers that represent interesting server behavior.

AI Integration Script (Python):

Python

import pandas as pd
import matplotlib.pyplot as plt

# Ethical Pre-computation: Assume an Intruder attack was run and results were
# saved as 'intruder_results.csv'. The columns are assumed to be:
# Position, Payload, Status, Length, Time
# This script analyzes that pre-existing data from an authorized test.

csv_file = 'intruder_results.csv'

# Use pandas to read the CSV data
try:
    df = pd.read_csv(csv_file)
    df.columns = ['Position', 'Payload', 'Status', 'Length', 'Time']
except FileNotFoundError:
    print(f"Error: The file {csv_file} was not found. Please export from Burp Intruder.")
    exit()

# Create a scatter plot
plt.figure(figsize=(12, 6))
plt.scatter(df.index, df['Length'], alpha=0.5)

# Highlight anomalies (e.g., response lengths that deviate significantly)
mean_length = df['Length'].mean()
std_dev = df['Length'].std()
anomalies = df[abs(df['Length'] - mean_length) > 2 * std_dev]
plt.scatter(anomalies.index, anomalies['Length'], color='red', label='Anomalies')

# Add labels and title for the report
plt.title('Intruder Response Length Analysis')
plt.xlabel('Request Number')
plt.ylabel('Response Length (Bytes)')
plt.legend()
plt.grid(True)

# Save the plot for the penetration test report
plt.savefig('intruder_analysis_plot.png')

print("Analysis complete. Plot saved to intruder_analysis_plot.png")
print("\nAnomalous Payloads Found:")
print(anomalies[['Payload', 'Status', 'Length']])

Script Breakdown:

Ethical Context & Use-Case: In a blind vulnerability assessment (like blind SQLi or content discovery), the only indicator of success is often a subtle change in response length. A Python script can programmatically ingest thousands of data points from an Intruder attack and use statistical analysis to identify anomalous responses that a human might miss. Generating a plot provides clear, visual evidence for a penetration test report, making the findings easier for the client to understand.

[VISUAL OUTPUT: A scatter plot image named intruder_analysis_plot.png. The plot shows hundreds of blue dots clustered around a central horizontal line (the average response length). A few red dots are scattered far above or below this line, clearly marked as anomalies.] --> Expected Output:

Analysis complete. Plot saved to intruder_analysis_plot.png

Anomalous Payloads Found:
       Payload  Status  Length
1337   OR 1=1     200     15432
2501   admin'#    200     15432
8080   ../../     200     812

Objective: Generate Context-Aware Wordlists with an LLM for Burp Intruder

This example demonstrates how to use a Large Language Model (LLM) to generate a highly specific wordlist for fuzzing directories or files based on the context of the target application.

AI Integration Script (Python with OpenAI API):

Python

import openai
import os

# Ethical Pre-computation: This script assumes the user has an API key and
# is authorized to perform directory enumeration on the target.
# The goal is to create a smarter wordlist than a generic one.

# Set your API key (best practice is to use environment variables)
# openai.api_key = os.getenv("OPENAI_API_KEY")
# For this example, we'll use a placeholder.
openai.api_key = "YOUR_API_KEY_HERE"

app_context = """
The web application is for a hospital patient management system.
It is built with Java Spring Boot and uses a Tomcat server.
Known sections include patient records, billing, appointments, and a doctor's portal.
"""

prompt = f"""
Based on the following application context, generate a wordlist of 50 potential
hidden file or directory names for security testing.
Include common framework-related paths and business-logic-related paths.
The output should be a single column of text, with one word per line.

Application Context:
{app_context}
"""

try:
    response = openai.Completion.create(
      engine="text-davinci-003",
      prompt=prompt,
      max_tokens=200,
      temperature=0.5
    )

    wordlist = response.choices[0].text.strip()

    # Save the wordlist to a file for Burp Intruder
    with open("ai_generated_wordlist.txt", "w") as f:
        f.write(wordlist)

    print("AI-generated wordlist saved to ai_generated_wordlist.txt")
    print("\n--- Sample from Wordlist ---")
    print("\n".join(wordlist.split('\n')[:10])) # Print first 10 lines

except Exception as e:
    print(f"An error occurred: {e}")
    print("Please ensure your API key is correctly configured.")

Script Breakdown:

Ethical Context & Use-Case: Generic wordlists like rockyou.txt are often inefficient for discovering hidden application endpoints. An LLM can be used as an intelligent assistant to generate a much smaller, higher-quality, and context-specific wordlist. By providing the AI with details about the application's purpose and technology stack (discovered during authorized recon), the resulting list is more likely to contain valid names (e.g., /actuator/health, /patient-api, /billing/export), making fuzzing attacks in Burp Intruder faster and more effective.

--> Expected Output:

AI-generated wordlist saved to ai_generated_wordlist.txt
