Bug Mastery is the ultimate ethical hacking tutorial app for learning how to find vulnerabilities in web applications, APIs, and networks. Whether you are a cybersecurity beginner or a seasoned researcher, this app gives you everything you need to master vulnerability discovery, exploitation, and responsible disclosure — all in one place.
Explore 100+ topics covering reconnaissance, web application security, OWASP Top 10, advanced exploitation, and professional reporting. Every topic includes clear explanations so you understand not just what each vulnerability is, but how to find, exploit, and report it.
MASTER VULNERABILITY HUNTING FROM BEGINNER TO ADVANCED
Getting Started — Learn what professional bug hunting is, how security programs work on platforms like HackerOne and Bugcrowd, and how to set up your environment. Understand responsible disclosure, scope, and ethics.
Reconnaissance — Master the critical first phase. Learn subdomain enumeration, port scanning, directory bruteforcing, fingerprinting, Google dorking, and OSINT techniques revealing hidden attack surfaces.
Web Fundamentals — Understand how web apps work. Learn HTTP methods, headers, cookies, sessions, authentication flows, and browser-server interactions.
OWASP TOP 10 AND CORE VULNERABILITIES
XSS — Master reflected, stored, and DOM-based cross-site scripting. Learn payload crafting, filter bypasses, and impact demonstration for effective reports.
SQL Injection — Understand classic, blind, time-based, and error-based SQLi. Learn data extraction, access escalation, and chaining for maximum impact.
Broken Authentication — Identify weak login mechanisms, session flaws, credential stuffing, and authentication bypass techniques.
SSRF — Exploit server-side request forgery to access internal services, cloud metadata, and restricted resources.
IDOR — Master insecure direct object reference detection to find authorization flaws exposing sensitive data.
CSRF — Understand cross-site request forgery, token validation weaknesses, and exploitation methods.
Security Misconfigurations — Find exposed admin panels, default credentials, verbose errors, and misconfigured cloud storage.
ADVANCED VULNERABILITY CLASSES
API Security — Test REST and GraphQL APIs for broken access controls, mass assignment, rate limiting bypasses, and information disclosure.
Business Logic Flaws — Discover bugs scanners miss. Identify race conditions, price manipulation, privilege escalation, and workflow bypasses.
File Upload Vulnerabilities — Understand unrestricted uploads, extension bypasses, and paths to remote code execution.
Subdomain Takeover — Identify dangling DNS records and unclaimed cloud resources for valid submissions.
REPORTING AND METHODOLOGY
Writing Reports — Master professional vulnerability reports. Write clear steps, demonstrate impact, assign severity, and communicate for faster rewards.
Hunting Methodology — Build a systematic workflow. Learn how top researchers approach targets, prioritize findings, and stay consistent across programs.
