first of all i know there is not any fast one click-y way to do this(if there is in a few days AVs will detect it)
i want to learn basics of process of making payloads undetected.
is there any good references for it?
what exactly should do?
what in assembly code of exe file we should change to make it undetected?
placing push ax pop ax in random palaces will make it undetected?
