Open a terminal and pass the input executable to the tool. pe2shc.exe target.exe shellcode.bin Use code with caution.
The code must use relative addressing (like RIP-relative addressing in x64 assembly) so it can execute from any arbitrary memory address.
The resulting file remains a valid EXE but can also be injected directly into memory and run as raw shellcode. 2. Donut (TheWover) convert exe to shellcode
Donut is not the only game in town.
This only works if your code does not use any global variables or external DLL calls, as those addresses will be broken once moved. Key Challenges Open a terminal and pass the input executable to the tool
Shellcode is a type of machine code that is designed to be executed directly by the computer's processor, without the need for an operating system or any other software. It is typically used in exploit code, which is designed to take advantage of vulnerabilities in software applications. Shellcode is usually written in assembly language and then compiled into machine code, which can be executed directly by the processor.
/GS- : Disables buffer security checks (which introduce absolute addresses). /O1 : Optimizes for smallest file size. /NODEFAULTLIB : Removes the standard C runtime library. Step 3: Extract the Text Section The resulting file remains a valid EXE but
#include <windows.h>
Instead of writing the entire loader by hand (error-prone), you can:
It adds a small bootstrap at the beginning of the EXE. When you jump to the start of the file, this bootstrap relocates the rest of the PE structure in memory.
For very simple, self-contained programs written in C or Assembly, you can extract the .text section directly.
