Doing some research about packing and such, I went on the possibility to use the old msfencode to generate a packed exe.
However, msfencode is not updated anymore (still found on kali however), and I wish to use the encoders on the x64 architecture.
By the way, I tested to use msfvenom simply to pack my executable, using the 'no payload' option as such : '-p -'. But, it just keeps asking me to supply a payload on stdin.
So, is it possible to just pack a binary using msfvenom?
