Setelah liat, ups. Judulnya menggoda kiddo seperti saya Dan bener, saya pun tergoda oleh rayuan sang demon Setelah compile dan nge-jalanin, kok ancur Selidik punya selidik, ternyata ada 1 baris code yang di hash di atas Apa itu ? Decode sendiri deh

Kalau saya kutip dari antihackerlink, ada baris yang menyatakan seperti ini :

But Please DO NOT EXECUTE it if you did not know anything about shell code.
Because there are a lines in there that will delete your entire hardisk !!!
You have to modify first from the source code, than (maybe) you can use it 

Enjoy
