  • The Boscloner's research piggybacks off of tremendous research projects, such as the Proxmark and the Bishop Fox Tastic RFID Thief
  • While the Boscloner has been proven to be exceptionally successful on real-world penetration testing assessments, it is considered a community research project, and there is always room for improvements, feature additions, and stability fixes.



The Boscloner/Proxmark3 (BC/PM3) board is based upon the available Proxmark3 design.  The BC/PM3 has the added following features. The BC/PM3 board has added 2x 8 Pin headers which breakout the SPI bus and extra IO on the PM3 board. The extra headers are used to allow a Boscloner “shield” to be plugged into and communicate with the PM3 board. The Boscloner Shield is intended to act as a gateway to the PM3 which allows for custom commands and functions to be added to the base functionality of the PM3. The shield also allows for many types of additional functions to be added, some of which were used on the Boscloner Shield board.

See below images of the BC/PM3 and the attached Boscloner Shield.

PM3 with Boscloner Shield


The Boscloner PM3 functionality is based upon the stock Proxmark ProxSpace project which contains all of the stock PM3 functionality. Instructions for setting using the Proxmark3 (all apply to using the Boscloner Proxmark3) can be found on the Proxmark3 github wiki here ( The modified source code for the Boscloner project is available from the Boscloner source package ( and can be used as a basis for further adding additional custom functionality to the Boscloner/PM3 environment.  


The Boscloner Shield (BCS) was designed as a shield to plug into the BC/PM3 board and add the following features. 


  • SPI gateway to send and receive custom commands from the BC/PM3 board.  
  • Bluetooth communication
  • OLED 128x64 LCD
  • Wiegand decoding plug in interface
  • Optional SD card expansion
  • 2x Push buttons
  • 2x User LEDs

The Boscloner shield uses a freescale kinetis MCU, which is a high performance and low cost processor very capable of handling any job that the user may want to do when working with the proxmark3 board. The source code was developed in Kinetis Design Studio (KDS) ( which is a free unlimited eclipse based IDE that users can use to modify the existing source to create their own custom functionality. The IDE runs on Linux or Windows OS. There are many types of additional functionality that could potentially be added to the Boscloner shield and new pieces of functionality can be easily added using this environment and the available source code.


The HID Maxiprox 5375 Long Range Reader can be purchased from a variety of sources, including eBay and Amazon. Expected average price is anywhere between $230 - $400:

The user can directly download the Boscloner APK application package from github ( There may be some warnings about installing an application from outside of the Google Play Store. Click OK on these warnings and install the Boscloner App.

The iOS app can be downloaded directly from the App Store:

Source code files for the Boscloner app for the purpose of revising the source code, adding features, etc.. can be found below:


  1. You must first “pair” with the HC-06/HC-05 device from the Bluetooth settings in the Android app. Be sure the Boscloner/PM3 is powered on and the Bluetooth LED is blinking. Go to Bluetooth settings from the Android settings, search, then pair with the found HC-06/HC-05 device.

    No manual pairing is required since we are now using the new BLE modules.

2) Once the HC-06 / HC-05 has been paired, you can open the Boscloner app and connect to the HC-06 / HC-05.  Select the HC06 / HC-05 from the drop down menu and press the Connect button. The pink “clone” button will light up and the terminal window will show MCU ACK (acknowledge).  

3)  The “Clone” button is enabled by default and will cause the Boscloner/PM3 to autoclone cards when the Maxiprox scans card data.

The terminal window will show the data that is “cloned” or “scanned” (only read and not cloned) in the terminal window.  When a card is “cloned” the card ID will be stored in the “History” window of the App.  

The user can view and clone card IDs directly from the “History” window from the Boscloner App.  

4) To clone a stored history value.  Click the “...” icon from the main window in the Boscloner App. This will bring up all stored ID values. Scroll to the ID you want to clone and Long Press the ID. A pop-up will ask you if you really want to clone this ID value. Click “OK” and the ID will be sent to the Boscloner/PM3 to be cloned. The result will be displayed on the OLED display of the Boscloner/PM3.


The Boscloner PM3 has the features outlined in the Overview section. The below image shows the given functions applicable to using the Boscloner to clone and scan cards.  

  • The Boscloner/PM3 connects to the Boscloner app through the Bluetooth adapter.
  • Update data is displayed on the OLED Display.  
  • Pushbutton enables and disables Auto Clone feature
  • The right Pushbutton resets the Shield board.  
  • The Wiegand connect is used to connect the Maxiprox Wiegand signals to the Boscloner Shield.  
  • Optional USB power is available through the micro USB connector
  • An optional microSD footprint is on the PCB for alternative storage functions


  • Power the Boscloner/PM3 using the Mini USB connector on the PM3 Board
  • Connect the Wiegand cable from the Maxiprox to the Wiegand Connector shown in the image
  • Connect a LF antenna to the PM3 board using the Hirose USB connector

Once the board is powered it will be “Auto-Clone” mode and once a card ID is received from the Wiegand Cable a clone will be run on the PM3 Board and LF Antenna.  The display will update with events that are occurring. The Auto-Clone feature can be enabled or disabled using the left push button.  Connect to the board using the Boscloner App to utilize more features.  

Desired Future Features

  • To add the ability to simply type in the ID values that the user wishes to write to a blank card, rather than relying solely on scanning new badges or using the history file.
  • Bug fixes
  • iOS App
  • App and Boscloner shield diversification to support other Wiegand cards, other than HID.


Boscloner/PM3 board

  • When the PM3 board is connected to a PC and a terminal connection has not been opened, the board will periodically lock up and reset. Tests have done with the original PM3 and the same problem occurs, therefore it is believed that the issue is within the USB driver code of the official Proxspace source code.  
  • The issue does not occur when the Boscloner/PM3 board is connected to a power supply, which is how the board is expected to be used during real-world applications.

    Boscloner Real-World Use

    • The Maxiprox “read” antenna is very strong, and can cause interference with the smaller “write” antenna that is used for cloning/writing to new badges. To remedy this, the write antenna and corresponding badge needs to be isolated from possible interference. This is achieved by using a faraday cage based approach. A simple paper cup (large enough to fit the “write” antenna, that is surround with tinfoil, is enough to prevent disruptive interference (See figure of simple faraday cage below). The Boscloner is designed to be used within a laptop messenger bag, but is flexible so as long as the “read” antenna does not interfere with the “write” antenna
    • The “write” antenna is weak, and the blank HID badge to be written must be very close and almost directly centered. To remedy this, one may simply attach a one-side sticky piece of velcro to both the HID badge itself, and the “write” antenna. This ensures it is easy enough to place the badge where it needs to be to be properly written to while the user moves around their environment.
