Mastering Bug Hunting: A Beginner’s Guide to Effective Methodologies

Bug bounty programs offer a fantastic opportunity to gain recognition and compensation by reporting security vulnerabilities to websites and software developers. This guide provides essential resources and strategies to help you dive into the world of bug hunting.

Recommended Books for Bug Hunting:

If you’re new to bug bounty hunting, these resources will introduce you to web application penetration testing and web exploitation, which are core skills in most bug bounty programs:

The Web Application Hacker’s Handbook — A comprehensive guide to identifying and exploiting web vulnerabilities.
OWASP Testing Guide — The essential guide from OWASP for secure web application testing.
Penetration Testing — A hands-on introduction to discovering vulnerabilities, perfect for beginners.
The Hacker Playbook 2: Practical Guide to Penetration Testing — Step-by-step strategies for penetration testing with real-world examples.

Practice Makes Bug Hunting Perfect:

Hands-on practice is essential to build and retain your skills. Use these platforms to test your knowledge in safe, simulated environments:

BWAPP — A free vulnerable web application to practice various security issues.

WebGoat — An intentionally insecure application from OWASP, perfect for learning about web app security.

RootMe — Offers a variety of challenges in web security and other areas.

OWASP Juice Shop — A vulnerable app for practicing web application hacking.

TryHackMe — A platform with structured training paths and rooms for both beginners and advanced learners.

Web Pentesting Checklists:

Use these checklists to organize your penetration testing process:

Pentestbook Checklist — A detailed guide covering various aspects of web testing.

OWASP Web Application Penetration Checklist — An official checklist from OWASP to help ensure you’ve covered all testing areas.

Bug Hunting Methodology

Define the Scope: Clearly identify the allowed targets and boundaries for testing.

Reconnaissance: Gather information about potential targets using subdomain enumeration tools like Sublist3r and VirusTotal.

Select and Analyze Targets: Choose specific targets and run scans to gather details (CMS, server, technologies in use).

Information Gathering with Google Dorks: Use search operators to reveal additional insights.

Service Review: Check open ports, applications, and services.

Fuzz Testing: Look for errors and hidden vulnerabilities through fuzzing techniques.

Exploit and Document Vulnerabilities: Create proof-of-concepts for identified weaknesses.

Essential Tools, Wordlists, and Payloads Tools for Reconnaissance and Scanning:

Nmap — Network scanning for identifying open ports and services.
Burp Suite — Comprehensive web vulnerability scanner.
WPScan — WordPress-specific security scanner.
Kali Linux — A powerful operating system pre-loaded with security tools.
Your Browser — Often the most underrated tool!

Wordlists for Testing:

SecLists — Wordlists for discovery, fuzzing, shell paths, and more.
Directory and Portable Wordlists — For directory discovery and file enumeration.
FUZZ-DB — Database of payloads and attack patterns for fuzzing.

Passive Reconnaissance Tools:

Shodan — A search engine for internet-connected devices.
BuiltWith — Technology profiler for discovering the tech stack behind websites.
Censys — Similar to Shodan, used for finding connected devices.
Whois — Domain and IP ownership information.
OSINT Framework — A framework for open-source intelligence gathering.

Payload Resources:

Payloads All The Things — A vast collection of attack payloads for different vulnerabilities.
XSS and SQL Injection Payloads — Specific payloads for cross-site scripting and SQL injection.
Google Dorks Payloads — Predefined Google Dorks for information discovery.
