so letamp;#39;s talk about modifying or patching binaries itamp;#39;s generally useful for cracking something but it has users beyond that sometimes you just want to change the behavior of a program a little bit and for example sometimes in CTF challenges you want to bypass some checks just to make the exploit development easier and then later you can go back and edit the check back in a very long time ago at the beginning of my channel I created this episode called reversing and cracking first simple program itamp;#39;s in the binary exploitation playlist and itamp;#39;s the episode hex 5 itamp;#39;s a very simple program that we are looking at we are basically just having a very very simple password check and back when I made this I decided to just dynamically show you that you can change the execution flow of a program so back then I just used gdb and then changed what happens at the if comparison and I didnamp;#39;t patch the binary because I thought that would add a bit too
