Bug Mastery vs Learn Cyber Security & Hacking

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.

Learn cyber security and ethical hacking from zero — no IT background required. Hands-on lessons on network security, web attacks, cryptography and defense, with quizzes, CTF-style challenges and an AI mentor that explains every concept. Built for beginners aiming at real security careers: SOC analyst, penetration tester, security engineer. WHY LEARN CYBER SECURITY? • Security is one of tech's fastest-growing, best-paid fields — and it's chronically short of people • You don't need a degree to start: fundamentals + hands-on practice + certifications is a proven path • Understanding how attacks work makes you valuable in ANY tech role • Every lesson is practical — how attacks actually happen and how defenders actually stop them WHAT YOU'LL LEARN • How attackers think — phishing, social engineering and malware • Network security — protocols, firewalls, scanning and monitoring • Web security — how injection, XSS and common vulnerabilities work, and how to prevent them • Cryptography — encryption, hashing and how secrets stay secret • Defense — hardening, incident response and security operations • Linux and command-line foundations for security work • Career paths and the concepts behind entry certifications EVERYTHING YOU NEED TO GET STARTED • AI Mentor — confused by a protocol or an attack chain? Ask anything and get a clear answer in seconds • 100+ bite-sized lessons (5–10 minutes each) — theory you can actually finish • Quizzes and CTF-style challenges after every topic to lock in what you learn • Weekly Challenge — compete with learners around the world • Certificate of completion — pass the final exam and prove your skills • Streaks, progress tracking and smart reminders to keep you consistent • Learn on the go — lessons load fast and keep working on flaky connections • App available in 22 languages WHO IT'S FOR • Complete beginners curious about hacking and defense • IT professionals moving toward security roles • Students preparing for security fundamentals and certification concepts • Developers who want to write code attackers can't break WHITE-HAT ONLY Everything in this app is taught for defense, education and legal, ethical use. Learning how attacks work is how defenders are made. Part of CoddyKit — a family of 40+ coding apps trusted by 100,000+ learners worldwide.
