Ayo Serang Balik Pengguna Netcut

K-Comunity akan membahas cara MENYERANG PENGGUNA NETCUT

Koneksi putus bukan menjadi sebuah dilema lagi, melainkan bisa dikarenakan beberapa sebab. Terutama di hotspot gratisan atau di warnet-warnet, kalau koneksi kita lemot dan tidak bisa akses internet dengan tidak normal, mungkin salah satunya karena ada pengguna warnet lainnya yang menggunakan NETCUT.

Agar tidak bete karena loading lama, serang balik saja pengguna NETCUT tersebut.

Langkahnya adalah:

Harus sudah terdapat python compiler di komputer
Download toolsnya disini: http://1337day.com/exploits/17338
Jalankan tools tersebut dengan compile: python filenameexploit.py [ethernet] [macaddress], contoh:python netcutkiller.py eth0 A1:B2:C3:D4:E5:F6
