Introduction
The bug bounty landscape is shifting faster than ever—AI-driven applications, cloud-native architectures, and API-first designs have created a new attack surface that demands updated methodologies. This roadmap, originally shared by Mohammed Nafeed and hosted on GitHub (https://lnkd.in/gFEhZdev), condenses years of real-world experience into a structured path for 2026. Whether you’re starting from zero or looking to refine your skills, this guide integrates essential tools, hands-on commands, and exploitation techniques across web, cloud, and AI domains.
Learning Objectives
- Build a complete bug bounty lab with isolated environments and industry-standard tooling.
- Execute every phase of an engagement: reconnaissance, vulnerability analysis, exploitation, and responsible disclosure.
- Apply modern techniques to test APIs, cloud misconfigurations, and AI-specific flaws.
You Should Know
1. Setting Up Your Bug Bounty Lab
A dedicated lab ensures you can test tools and payloads without affecting production systems.
Step‑by‑step guide:
- Install a penetration testing distribution – Kali Linux is the industry standard. On VMware or VirtualBox, download the ISO and install. Alternatively, use Windows Subsystem for Linux (WSL) with Kali:
On Windows (PowerShell as Admin) wsl --install -d kali-linux
- Update and install core tools:
sudo apt update && sudo apt full-upgrade -y sudo apt install kali-linux-headless installs a meta-package of tools
- Set up vulnerable targets – Docker makes this easy:
OWASP Juice Shop (Node.js web app) docker pull bkimminich/juice-shop docker run -d -p 3000:3000 bkimminich/juice-shop Damn Vulnerable Web Application (DVWA) – PHP/MySQL docker pull vulnerables/web-dvwa docker run -d -p 80:80 vulnerables/web-dvwa
- Configure Burp Suite Community – Download from PortSwigger, set up FoxyProxy to route browser traffic through
127.0.0.1:8080, and install the CA certificate for HTTPS interception.
2. Reconnaissance: The Art of Gathering Intelligence
Reconnaissance is the foundation of any successful bounty. Modern recon combines passive and active techniques.
Step‑by‑step guide:
- Subdomain enumeration – Use Amass for passive data and brute‑forcing:
amass enum -passive -d target.com -o subdomains.txt amass enum -brute -w /usr/share/wordlists/seclists/Discovery/DNS/subdomains-top1million-5000.txt -d target.com
- Port and service scanning – Nmap with version detection and default scripts:
nmap -sV -sC -p- -T4 -oA nmap_scan target.com
- Content discovery – Ffuf (or gobuster) to find hidden directories and files:
ffuf -u https://target.com/FUZZ -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -c -t 50
- GitHub dorks – Search for exposed API keys or credentials using tools like
gitdorker:gitdorker -tf TOKENS_FILE -q "target.com" -d dorks/DEFAULT_DORKS.txt -o output
3. Vulnerability Analysis and Detection
Automated scanners save time, but manual verification is critical to avoid false positives.
Step‑by‑step guide:
- Automated scanning with Nuclei – Use templates for known CVEs and misconfigurations:
nuclei -u https://target.com -t ~/nuclei-templates/ -severity critical,high,medium -o nuclei_results.txt
- SQL injection detection – Test parameters with sqlmap, but always verify manually:
sqlmap -u "https://target.com/page?id=1" --dbs --random-agent --batch
- XSS discovery – Use a combination of automated (XSStrike) and manual payloads:
python3 xsstrike.py -u "https://target.com/search?q=test"
- API endpoint fuzzing – Use Postman or Burp Intruder to send malformed JSON/GraphQL queries and observe error messages.
4. Exploitation and Proof of Concept
Moving from detection to exploitation demonstrates real impact. Always stay within legal boundaries.
Step‑by‑step guide:
- Insecure Direct Object References (IDOR) – After discovering an endpoint like
/api/user/123, increment IDs and check if you can access another user’s data. Use Burp Repeater to automate:GET /api/user/124 HTTP/1.1 Host: target.com
- File upload vulnerabilities – Attempt to upload a web shell (e.g., `shell.php` with
<?php system($_GET['cmd']); ?>). Bypass filters using double extensions or magic bytes. - Server‑Side Request Forgery (SSRF) – If an endpoint fetches a URL (e.g.,
/fetch?url=), try `file:///etc/passwd` or `http://169.254.169.254/latest/meta-data/` to access cloud metadata. - Crafting a PoC with Python – Automate exploitation for complex logic flaws:
import requests url = "https://target.com/vulnerable-endpoint" payload = {"user": "victim", "action": "transfer", "amount": 1000} headers = {"Authorization": "Bearer <attacker_token>"} r = requests.post(url, json=payload, headers=headers) print(r.status_code, r.text)
5. API and Cloud Security Testing
Modern targets often expose REST/GraphQL APIs and reside in the cloud. Misconfigurations are goldmines.
Step‑by‑step guide:
- REST API testing – Use Burp to capture requests, then test for mass assignment (sending extra parameters) and improper HTTP methods (e.g., `PUT` on a read‑only endpoint).
- GraphQL introspection – Query the schema to discover hidden queries:
query { __schema { types { name fields { name } } } } - AWS S3 bucket enumeration – Check for public buckets using AWS CLI:
aws s3 ls s3://target-bucket --no-sign-request aws s3api get-bucket-acl --bucket target-bucket
- Cloud metadata endpoints – If SSRF exists, try cloud provider metadata:
- AWS: `http://169.254.169.254/latest/meta-data/`
– GCP: `http://metadata.google.internal/computeMetadata/v1/` - Azure: `http://169.254.169.254/metadata/instance?api-version=2017-08-01`
6. Reporting and Responsible Disclosure
A clear, actionable report increases your chance of bounty and builds trust.
Step‑by‑step guide:
- Structure your report – Use templates from platforms like HackerOne. Include:
- Summary – One‑paragraph description of the vulnerability.
- Steps to reproduce – Numbered steps with exact URLs, parameters, and payloads.
- Impact – Explain what an attacker could achieve (e.g., data theft, account takeover).
- Remediation – Suggest fixes (input validation, access controls, etc.).
- Use screenshots and videos – Annotate critical parts.
- Communicate professionally – Be patient with triage teams; provide additional info if requested.
7. Continuous Learning and Keeping Up
The bug bounty field evolves rapidly. The GitHub roadmap for 2026 (https://lnkd.in/gFEhZdev) includes curated resources, but you must stay engaged.
Step‑by‑step guide:
- Follow researchers – Twitter, LinkedIn, and blogs (PortSwigger Research, Detectify Labs).
- Participate in CTFs – Platforms like HackTheBox, TryHackMe, and PentesterLab offer hands‑on practice.
- Contribute to open‑source – Submit new Nuclei templates, improve reconnaissance tools.
- Join bug bounty platforms – Start on HackerOne, Bugcrowd, or Intigriti with public programs.
What Undercode Say
- Key Takeaway 1 – The 2026 roadmap underscores that automation (Nuclei, FFuF) handles the low‑hanging fruit, but manual creativity—especially in business logic and AI/cloud misconfigurations—separates top hunters.
- Key Takeaway 2 – Practical lab work with Docker and vulnerable apps is non‑negotiable; you cannot learn exploitation solely from theory.
- Analysis – The shift toward AI and serverless means hunters must understand how models are trained, how APIs are exposed, and how cloud IAM policies can be abused. The GitHub repository linked provides a living document that adapts to these trends, making it an essential bookmark for 2026.
Prediction
By 2026, bug bounty programs will prioritize AI model extraction attacks, prompt injection in LLMs, and serverless function misconfigurations. Automated scanners will dominate common web flaws, pushing hunters to specialize in complex, chained exploits that require deep architectural understanding. The roadmap’s emphasis on cloud and API security reflects this inevitable evolution.
