5 Steps Wifi Hacking – Cracking WPA2 Password security

Today we will learn about 5 Steps Wifi Hacking – Cracking WPA2 Password.After the long time I  come  back with  very  importent  topic that  is  how to  hack  wifi  even  in  wpa2 password  security,   first  I want to  give  some  idea  about  wifi  security  so  ...

what  Wikipedia say  about  security of  wifi:

    Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols and security certification programs developed by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the previous system, WEP (Wired Equivalent Privacy).A flaw in a feature added to Wi-Fi, called Wi-Fi Protected Setup (WPS), allows WPA and WPA2 security to be bypassed and effectively broken in many situations. Many access point they have a Wifi Protected Setup enabled by default (even after we hard reset the access point).

what  is  your  Requirements ?

1. ) first  of  all you  need  Wireless card (support promiscuous mode)

note:In this tutorial I use ALFA AWUS036H from Amazon.

2.) Access point with WPA2 and WPS enables

5 Steps Wifi Hacking – Cracking WPA2 Password:

step:1.) first  of  all  you  Open our terminal if  you  don't  know how  simply  press (CTRL+ALT+T) and typeairmon-ng  (this command will lists our wireless card that attached with our system.

step:2.)after  that  our next step is  ,we need to stop our wireless monitor mode by running 

airmon-ng stop wlan0

step:3.) Now we ready to capture the wireless traffic around us. By running airodump-ng wlan0 our wireless interface will start capturing the data.

after  exicuting proper  commmand  ,From the picture above, we can see many available access point with all the information. you  see In the green box is our victim access point but here  it is  my  own access point :-)

some  Information you want  to  need:

BSSID (Basic Service Set Identification): the MAC address of access point

PWR: Signal level reported by the card.

Beacons: Number of announcements packets sent by the AP

#Data: Number of captured data packets (if WEP, unique IV count), including data broadcast packets.

#/s: Number of data packets per second measure over the last 10 seconds.

CH: Channel number (taken from beacon packets).

MB: Maximum speed supported by the AP. If MB = 11, it's 802.11b, if MB = 22 it's 802.11b+ and higher rates are 802.11g.

ENC: Encryption algorithm in use.

CIPHER: The cipher detected. TKIP is typically used with WPA and CCMP is typically used with WPA2.

AUTH: The authentication protocol used.

ESSID: Shows the wireless network name. The so-called “SSID”, which can be empty if SSID hiding is activated.

step:4.)  From the step 3 above, we can find access point with encryption algorithm WPA2 and make  sure  you  note the AP channel number. Now we will find out whether target AP has WPS enabled or not.execute following  command

wash -i wlan0 -c 8 -C -s

here  you  see   WPS Locked status is No, then we ready to crack and move to step 5  without  wasting  time.

step:5) after that  The last step is cracking the WPA2 password  for  this  we  use  reaver. exicute following  command

reaver -i -b –fail-wait=360

note: Because we already get the information from step 3 above, so my command look like bellow  format:

reaver -i wlan0 -b E0:05:C5:5A:26:94 –fail-wait=360

importent: it took about 5 hours to crack 19 characters WPA2 password from my Kali virtualBox, but it depend with our hardware and wireless card.

security tips:

1. WPA and WPA2 security implemented without using the Wi-Fi Protected Setup (WPS)  are unaffected by the security vulnerability.

2. To prevent this attack, just turn off our WPS/QSS feature on our access point.

Instruction for you:  this  is  make  sure that Only practice this tutorial on your own lab and your own device. Hacking can be a crime if you don't know where to put it.me  and  this  website  is  not  responsible  for  the  action  taken  by  your  victim if you  harm him/her.
