10: Bypassing Stack Canaries (leak + write) - Buffer Overflows - Intro to Binary Exploitation (Pwn)
10th video from the "Practical Buffer Overflow Exploitation" course covering the basics of Binary Exploitation. NX and stack canaries are enabled this time, so we'll use a printf() format string vulnerability leak the stack canary, allowing us to overwrite it with the expected value. We'll use checksec, ghidra, pwndbg and pwntools! Write-ups/tutorials aimed at beginners - Hope you enjoy 🙂 #BinaryExploitation #BufferOverflow #BinExp #RE #Pwn #PwnTools
