Golang execute child process from binary data in memory

Question

I know that it is possible to embed executables in Golang executables and run them, or run Golang code from a string using projects like Yaegi , but is it possible to run a binary stored as a variable without writing it to a file , as a child process? The binary is already in memory as a variable so is it possible to just execute it somehow?

If I'm not mistaken there is a difference between executable memory and data memory so would that prevent this from being done?

The reason for my question is that I'm writing an open-source RAT/payload dropper as a project to learn Golang and would like to make is as modular as possible, including file-less updates and binary (also file-less) payloads.

EDIT: Any solution is welcome, but cross-platform solutions are preferred.

EDIT2: According to this SO answer, this is not possible / very difficult in C++. Seemingly, the main reason for this is dynamically linking libraries. As Golang is statically linked, would this be any easier?

Answer 1

No, there is no portable way to do this.

Answer 2

Yes, try this way to do this. https://github.com/amenzhinsky/go-memexec
