Introduction to Binary Exploitation - Practical Buffer Overflow Challenges for Beginners

Learn binary exploitation fundamentals through hands-on buffer overflow challenges designed for beginners in this comprehensive video tutorial series. Master essential cybersecurity tools including Ghidra, IDA, Radare2, GDB with PwnDbg/GEF/PEDA extensions, PwnTools, Checksec, ropper, and MSFVenom through practical demonstrations. Develop exploits to overwrite stack variables, redirect program execution to chosen functions using ret2win techniques, supply function parameters, inject shellcode, and perform return-to-libc attacks including ret2system exploits. Explore format string vulnerabilities to overwrite Global Offset Table (GOT) entries, leak Position Independent Executable (PIE) and libc addresses, and bypass stack canaries. Practice manual exploit development alongside automated approaches using PwnTools for both 32-bit (x86) and 64-bit architectures while utilizing PwnDbg for debugging. Progress through eleven structured modules covering introduction and setup, stack variable overwriting techniques, return-to-win exploits with function parameters, shellcode injection using Shellcraft and MSFVenom, return-to-libc attacks with one_gadget, format string vulnerability exploitation through printf, PIE and libc leaking for bypass techniques, GOT entry overwriting, and stack canary bypass methods. Access accompanying binary files, source code, and exploitation scripts through the provided GitHub repository to practice alongside the demonstrations.
