All I want for Christmas is to understand why my shellcode crashes the calling Python process... (executing shellcode with ctypes, kernel32 VirtualAlloc & RtlMoveMemory) Black Hat Python book with msfvenom

Hello all,

Hopefully there are some folks that have some experience with this. I'm going through the Black Hat Python book, and I'm working on Chapter 8: Pythonic Shellcode Execution. Using the following msfvenom commads:

msfvenom -p windows/x64/messagebox TEXT="Test Msg" TITLE="Test Title" -b '\x00' '\x0A' '\x0D' '\xFF' '\x20' EXITFUNC=thread -o msg.raw
base64 -w 0 -i msg.raw > msg.bin

msfvenom -p windows/x64/exec -f raw cmd=calc.exe -b '\x00' '\x0A' '\x0D' '\xFF' '\x20' EXITFUNC=thread -o calc.raw
base64 -w 0 -i calc.raw > calc.bin …
