minimal environment for shellcode development in linux. For now supports x86.
- edit shellcode.asm file
- execute "make asm=shellcode.asm"
- Wow !
a quick example of exit(0) shellcode:
section .text
global _start
_start:
xor ebx, ebx
xor eax, eax
inc eax
int 0x80saved as examples/shellcode.asm.
make asm=examples/shellcode.asm
::: x86 Shellcode Factory :::
::: Your piece of art :::
examples/shellcode.out: file format elf32-i386
Disassembly of section .text:
08048060 <_start>:
8048060: 31 db xor ebx,ebx
8048062: 31 c0 xor eax,eax
8048064: 40 inc eax
8048065: cd 80 int 0x80

examples/shellcode.bin contains our precious shellcode :)
