Want to check the security of your network? In the past, to do that, you would usually need a computer equipped with a specific wireless network card and pre-installed with an operating system, such as Windows or Linux. However, now, with only certain Android devices, you can scan and crack wireless networks. These tools are all provided for free, as long as your device is compatible. Note that breaking into a router without permission is illegal. The steps below will show you how to check your own network security.

Jailbreak compatible device. Not all Android phones or tablets can crack the WPS PIN. It must be a device with a bcm4300 or Broadcom bcm4329 wireless microprocessor and must be a jailbroken device. You will have the best chance of success with Cyanogen ROM. Some of the supported devices include:

  • Nexus 7
  • Galaxy S1/S2/S3/S4/S5
  • Galaxy y
  • Nexus One
  • Desire HD
  • Micromax A67

Download and install bcmon. This tool turns on Monitor Mode on the Broadcom microprocessor – the component that plays a very important role in PIN cracking. The bcmon APK file is freely available from the bcmon page of the Google Code website.

  • To install the APK file, on the Security menu, you will have to allow installation from unknown sources.

Run bcmon. Once the APK file has been installed, run the app. Install firmware and tools when required. Tap the “Enable Monitor Mode” option. If the app freezes, open it and try again. If three times and still not, your device is most likely not supported.

  • To run bcmon, your device must be jailbroken.

Note down the displayed MAC address. This is the MAC address for the router. If the list lists different routers, make sure that’s the correct MAC address you need. Record this address.

  • Also, you need to record the Channel that the access point is using to broadcast the signal.

Start scanning for channels. You will have to gather information from the access point for several hours before you can attempt to crack the password. Type airodump-ng -c channel# --bssid MAC address -w output ath0 and press Enter. Airodump will start scanning. You can leave the device somewhere for a while while it scans for information. Make sure the device is plugged in if the battery is low.

  • Replace channel# with the channel number that the access point is using to transmit (such as 6).
  • Replace the MAC address with the router’s MAC address (such as 00:00a:95:9d:68:16).
  • Continue scanning until at least 20,000-30,000 packets are obtained.

Note down the hexadecimal password when done. When the password cracking process (which can take up to several hours) is complete, the Key Found! (Key Found!) appears. Next is the key in hexadecimal. For the key to work, make sure that “Probability” is 100%. [1]

  • When entering the key, do not enter the “:” sign. For example, if the key found is 12:34:56:78:90, enter 1234567890 .

    Start the jailbreak process. Click the “Start attack” button located at the bottom of the Reaver Settings menu. The screen is opened and the results of the ongoing jailbreak are displayed.

    • WPS Jailbreak can take anywhere from 2 to 10+ hours to complete and is not always successful. [2]

    • Warning

    • Unauthorized access to a router that you are not authorized to access is illegal.
    • In the US and UK, where unauthorized access to a WiFi connection is illegal, getting someone involved in these activities is also subject to fines or arrest.

    Advice

    • Under the common computer unauthorized access law (in the Netherlands), someone who illegally accesses a WiFi router cannot be prosecuted because a WiFi router does not conform to the computer definition set forth under Dutch law. Lan.
