Hey! interesante
ReplyDeletetambien se puede usar el comando hexdump desde terminal, si le pones el -C te pinta lo mismo que el editor hex.
Me pregunto si con este tipo de tecnica se podra inyectar el shellcode a un exe para hacer un buffer overflow :o
algun uso le podre dar :)
Vale la pena intentar lo que sugiere Eve ;) +1 para N3P.
