3rd video from the "Practical Buffer Overflow Exploitation" course covering the basics of Binary Exploitation. In this video we'll exploit a buffer overflow vulnerability and redirect the flow of execution to a function of our choice (return to win). We'll use checksec, ghidra, pwndbg and create a couple of pwntools scripts, automating finding the EIP/RIP offset and making use of ROP objects! Write-ups/tutorials aimed at beginners - Hope you enjoy 🙂 #BinaryExploitation #BufferOverflow #BinExp #RE #Pwn #PwnTools
