Cyber Security Complete Course 2026 | From Zero to Job Ready Ethical Hacker + Blue Team Expert | The Techzeen - I Bypassed the Password 😱 Binary Patching with Ghidra (Reverse Engineering Lab) 2026

One small patch… and the password check was gone. 😱 This is the real power of Reverse Engineering. In this video of the Cyber Security Course, I perform a complete hands-on Reverse Engineering practical using Ghidra. You’ll see how attackers analyze binaries, extract hidden details, and perform binary patching to bypass authentication logic. This is one of the most important practical labs for anyone serious about malware analysis, ethical hacking, or software security. ⏳ TIMESTAMPS (The Ghidra Mastery Lab) 0:00 - Inside the Binary: How Reverse Engineering Decodes Any Software 🧠 1:24 - Lab Setup: Building a Protected C-Program for Security Testing 3:36 - Forensic Analysis: Extracting Hardcoded Strings from Binaries 🔍 4:47 - The NSA Secret: Why Ghidra is the World’s Most Powerful RE Tool 5:36 - Deployment: Installing & Configuring Ghidra on Kali Linux 6:00 - Initialization: Launching the Ghidra Reverse Engineering Suite 6:22 - Data Ingestion: Importing Executables & Setting Up the Project 7:40 - Static Analysis: Deconstructing File Headers & Logic Maps 8:40 - Code Recovery: Using the Ghidra Decompiler to Read Source Logic 9:32 - Binary Patching Live: Manipulating Assembly Jumps to Bypass Auth 🛠️ 12:13 - Re-Compiling the Exploit: Exporting the Modified Patched Binary 12:40 - THE FINAL BOOM! Executing the Bypass — Access Granted! 💥 📘 Topics Covered * Reverse Engineering practical walkthrough * Creating and compiling a protected program * Extracting hidden strings from binaries * Introduction to Ghidra powerful features * Binary analysis using disassembler & decompiler * Understanding password check logic * Binary patching concept (live demo) * Exporting patched executable * Real demonstration of password bypass * Why binary patching is dangerous 🧪 Practical Highlights In this hands-on lab, I demonstrated: ✅ Creating a C program with admin password ✅ Compiling into executable binary ✅ Reading sensitive strings from binary ✅ Installing and setting up Ghidra ✅ Importing and analyzing the binary ✅ Exploring assembly and decompiled code ✅ Performing live binary patching ✅ Exporting modified executable ✅ Demonstrating authentication bypass 👉 This gives you real reverse engineering experience — not just theory. 🎓 Course Context 📚 Cyber Security Course (2026) – Advanced Concepts This lab is a critical step toward real malware analysis and software security research. ⚠️ Educational Purpose This video is created strictly for educational and ethical security awareness purposes. ❗ Do NOT use these techniques on software you don’t own or don’t have permission to test.
