🌐 What is Burp Suite?

Burp Suite, developed by PortSwigger, is a popular platform for web security testing. It is widely used by penetration testers, ethical hackers, bug bounty hunters, and security researchers.

🎯 Key Features of Burp Suite

HTTP/S interception
Manual request modification
Automated scanning (Pro/Enterprise editions)
Vulnerability identification (e.g., XSS, SQLi)
Repeater, Intruder, Spider tools
Plugin support via the BApp Store

🧰 Versions of Burp Suite

Community Edition (Free): Basic manual tools
Professional Edition (Paid): Adds automation, scanner, and collaborator
Enterprise Edition (Paid): Designed for automated CI/CD scanning in dev pipelines

Burp Suite is ideal for testing modern web applications that use JavaScript-heavy interfaces, REST APIs, and authentication mechanisms.

🛠️ Setting Up Burp Suite and Your Browser

📥 Step 1: Download and Install

Visit Burp Suite’s official download page
Choose your OS (Windows/Mac/Linux)
Download and install the Community or Professional version

🌐 Step 2: Configure Browser to Route Traffic

Burp Suite uses a proxy to intercept web traffic. To make this work:

Launch Burp Suite
Go to Proxy > Options
Ensure it’s listening on 127.0.0.1:8080

Firefox (Recommended):

Open Settings > Network Settings > Manual Proxy
HTTP Proxy: 127.0.0.1, Port: 8080
Check: “Use this proxy server for all protocols”

Chrome:

Use an extension like FoxyProxy to configure Burp for Chrome.

🔐 Step 3: Install Burp’s CA Certificate

HTTPS websites won’t load properly unless you install Burp’s certificate.

Open your browser and visit http://burp
Download the certificate
Import it in browser settings (Certificates > Authorities)
Trust the certificate for website identification

Now you’re ready to start intercepting HTTPS and HTTP traffic.

💡 Tip: Always test in a separate browser profile to avoid logging into your real accounts during testing.

🗺️ Burp Suite Interface Overview

The interface is divided into tabs, each performing specific roles:

🔍 Target

Displays site map
Visualizes attack surface
Organizes requests by domain

🔐 Proxy

Intercepts requests/responses
Allows real-time modification

🔄 Repeater

Manually modify and resend requests
Analyze server responses

⚙️ Intruder

Automates payload delivery for brute force and fuzzing

🕷 Spider (deprecated in newer versions)

Crawls applications to discover endpoints

📊 Scanner (Pro only)

Automated vulnerability scanner
Identifies OWASP Top 10 issues

📦 Extender

Add tools and features via BApp Store

👁 Logger++ (Extension)

Logs all requests/responses in detail

🔄 Common Tools in Action

🛡️ Proxy Tab

Use it to:

Intercept HTTP/S requests
View headers, parameters, cookies
Modify requests before reaching the server

You can forward or drop requests, modify query strings, POST data, and cookies.

🧪 Repeater Tab

This is your manual testing playground:

Send request
Modify parameters
Analyze response

Great for testing:

Cross-Site Scripting (XSS)
SQL Injection
Authentication mechanisms

🚀 Intruder Tab

Used for brute force, fuzzing, or testing multiple payloads. Modes:

Sniper: One payload at a time
Battering Ram: Same payload across positions
Pitchfork: Parallel payloads
Cluster Bomb: Combinatorial testing

Useful for:

Testing login forms
Hidden fields
Session tokens

🧭 Target Tab

Maps the entire web application
Click on pages to see their requests
Set Scope to limit attacks to your targets only

⚠️ Caution: Always define Scope before attacking to avoid hitting unauthorized systems.

🔍 Performing Basic Web Testing with Burp

Here’s a beginner-friendly workflow:

Step-by-Step Testing Workflow

Configure proxy and browser
Browse the application to build target map
Set target scope
Intercept requests via Proxy
Send suspicious requests to Repeater
Use Intruder for automated payloads
Log results and take notes

Use Burp Suite Labs or vulnerable web apps like:

💣 Identifying Web Vulnerabilities

✅ Cross-Site Scripting (XSS)

Insert scripts into input fields and observe execution:

<script>alert('XSS')</script>

If the script runs, it’s a reflected or stored XSS vulnerability.

✅ SQL Injection

Inject SQL payloads like:

admin' OR '1'='1 --

Watch for:

Login bypass
SQL error messages
Unexpected data

✅ Broken Authentication

Use Intruder to brute force login or reset endpoints. Test:

Weak credentials
Password reset tokens

✅ CSRF (Cross-Site Request Forgery)

Re-use intercepted POST requests without CSRF tokens.

✅ Insecure Direct Object Reference (IDOR)

Manually change object IDs in URLs (e.g., user/1002) to access unauthorized data.

✅ Server-Side Request Forgery (SSRF)

Inject internal IPs or URLs into form inputs or headers. Monitor responses or use Collaborator.

🔎 Don’t forget to test for HTTP Header Injection, Open Redirects, and Session Mismanagement.

🔌 Using Extensions for More Power

Replay session cookies
Modify JWT tokens

📈 Rate Limiting Tests

Use Intruder with high-speed payloads
Identify endpoints lacking throttle controls

🔂 Session Management Testing

Check session fixation
Test cookie flags (HttpOnly, Secure, SameSite)

🧠 Best Practices for Web Testing

✅ Ethical & Legal

Always have written permission before testing
Never scan production apps without approval
Use isolated labs for learning

✅ Technical Guidelines

Define Scope clearly
Avoid overloading systems
Keep logs for each finding
Use unique payloads for different inputs

✅ Continuous Learning Resources
