raspberry p

I was interested in learning ARM assembly language for developing small applications for microcontrollers. I wrote this small piece of shellcode which will write “127.0.0.1 google.lk” inside the /etc/hosts file in a Linux system. I used my Raspberry Pi model B+ for this 🙂

We will be needing the following syscalls.

[code language=”c”]
#define __NR_exit (__NR_SYSCALL_BASE+ 1)
#define __NR_write (__NR_SYSCALL_BASE+ 4)
#define __NR_open (__NR_SYSCALL_BASE+ 5)
#define __NR_close (__NR_SYSCALL_BASE+ 6)
[/code]
