Investigation

Online Tools

  • Wireless Network Mapping. If you have the BSSID, you can get the location. You need to create an account to use the advanced search.

Check Status

  • Retrieve the Device IP Address

    # IP address
ip addr
# IP address - Show the specific interface only
ip addr show eth0
ip addr show eth1
ip addr show tun0

# IPv4 only
ip -4 addr
# IPv6 only
ip -6 addr

# Static route
ip route

  • Delete Network Interfaces From Your Devices

    ip link delete docker0

  • Find Current WiFi IP Address

    We can get the ip adress of the WiFi that we’re currently connecting by checking a default gateway in results of ipconfig command.

    ipconfig

# Outputs

...

Default gateway . . . . . : 192.168.1.1

  • Find Another Computer's IP Address/MAC Address on Network

    arp -av

  • Get Public IP Address

    We can get our public ip address from command line as below.

    curl https://api.ipify.org

    Alternatively, we can get the public ip online like https://www.whatismyip.com/.

Crack WiFi Passwords

Default Router Credentials

admin:Admin
admin:admin
admin:password
admin:Michelangelo
root:admin
root:alpine
sitecom:Admin
telco:telco

Crack from A Packet Capture File

If we have a packet capture file (.cap or .pcap) of the WiFi network, we can crack the WiFi password using the file.

aircrack-ng example.cap -w wordlist.txt

Find BSSID From SSID

  1. Access to WiGLE and login.

  2. Go to View → Advanced Search.

  3. Open the General Search tab.

  4. Input the SSID in the SSID/Network Name.

  5. Check the result.

MAC Address Spoofing

  1. Preparation

    # Show available interfaces
airmon-ng

# Put an interface into monitor mode
airmon-ng start wlan0
airmon-ng start eth0
# or
iwconfig wlan0 mode monitor
iwconfig eth0 mode monitor

# Choose the access point (monitor mode)
airodump-ng wlan0mon

  2. Retrieve Client's MAC Addresses

    # Retrieve client's MAC address from the chosen access point
# -c 9: channel 9
# --bssid: target router MAC address
# -w psk: the dump file prefix
# eth0: interface name
airodump-ng -c 6 --bssid XX:XX:XX:XX:XX:XX -i wlan0mon
airodump-ng -c 9 --bssid 00:14:6C:7E:40:80 -w psk eth0

  3. Spoof MAC Address using the Retrieved Address

    # Take down the network at first
ip link set wlan0 down

# Set MAC address which you got by airodump-ng in the previous section
macchanger -m XX:XX:XX:XX:XX:XX wlan0

# Bring up the network
ip link set wlan0 up

  4. Confirmation

    # Check the current MAC address
macchanger -s wlan0

  5. Reset to the Original MAC Address

    # Reset to the original (permanent) MAC address
macchanger -p wlan0

Other Useful Tools

  • The Swiss Army knife for 802.11, BLE, IPv4 and IPv6 networks reconnaissance and MITM attacks.

  • List of MAC OUI (Organizationally Unique Identifier). You can get the information from the BSSID.

    • Access to the OUI Standards

      If the target BSSID is "B4:5D:50:AA:86:41", search text by inputting "B4-5D-50" on the string search. Then check the information.

First of all, you need to use network adapter which has monitor mode on your machine. is a complete suite of tools to assess WiFi network security.
