go-shellcode

1. Use xorme to convert a raw Shellcode to a XOR slice of bytes.
2. Replace the EncBuf variable in utils/payload.go.
3. Ensure your Build matches your Payload architecture.
4. Build using -ldflags "-s -w".

A few notes on Windows targets (basic protections enabled):

• To avoid detection, memory protection on execution is restricted to read and execute.
• Due to above reason the provided raw Shellcode CAN NOT be encoded otherwise won't work.
• Avoid using a staged Payload, it will get detected during the 2nd stage.
• Build AMD64 binaries and use x64 Payloads for ARM64 targets to avoid Payload limitations.

A note on Linux targets:

• Some (or all?) non staged msfvenom payloads only allow elf as the output format, so you'll have to relay on staged Payloads which is OK except in some specific circumstances.
