2nd video from the "Practical
2nd video from the "Practical Buffer Overflow Exploitation" course where we cover the basics of Binary Exploitation. In this video we'll build upon the last video to overwrite an important local function variable on the stack. The last challenge required any non-zero input to bypass but this time, the password/key on the stack needs to be overwritten with a specific value. We'll use checksec, ghidra, pwndbg and create another basic pwntools script! Write-ups/tutorials aimed at beginners - Hope you enjoy 🙂 #BinaryExploitation #BufferOverflow #BinExp #RE #Pwn #PwnTools
