int main() { char shellcode[] = "\x55\x48\x8b\x05\xb8\x13\x00\x00"; // Your shellcode here int (*func)() = (int (*)())shellcode; func(); return 0; } Compile and run it:
gcc -o example.exe example.c Use objdump to extract the binary data from the EXE file: convert exe to shellcode
def exe_to_shellcode(exe_path): # Extract binary data subprocess.run(["dumpbin", "/raw", exe_path], stdout=open("example.bin", "wb")) This guide provides a basic overview of the process
# Usage: shellcode = exe_to_shellcode("example.exe") print(shellcode.hex()) Note that this is a simplified example. Depending on your specific requirements, you might need to adjust the process. Converting an EXE file to shellcode involves several steps, including extracting binary data, removing headers and metadata, and aligning the shellcode to a page boundary. This guide provides a basic overview of the process. However, keep in mind that the specifics may vary depending on your use case and requirements. Always ensure you're working with legitimate and authorized data when experimenting with shellcode. # Align to page boundary subprocess
# Align to page boundary subprocess.run(["msvc", "-c", "example.bin.noheader", "-Fo", "example.bin.aligned"])
# Remove headers and metadata subprocess.run(["dd", "if=example.bin", "of=example.bin.noheader", "bs=1", "skip=64"])
