Does anybody use any tools other than msfvenom for producing shellcodes?
I used it as a starting point for the Execute challenge. But when I tried entering the entire list of bad characters, msfvenom would just fail.
However, I was able to just manually re-write a lot of the opcodes to equivalent instructions fairly easily. So is there a utility that can just automatically do that for me? I’m just trying to do this faster next time around.
