Many of us use a 4 digit pin code to lock our phones. [David Randolph] over at Hak5 has come up a simple way to use a 3D printer to brute force these passwords. Just about every 3D printer out there speaks the same language, G-code. The same language used in CAD and CNC machines for decades.
[David] placed a numeric keypad on the bed of his printer. He then mapped out the height and positions of each key. Once he knew the absolute positions of the keys, it was easy to tell the printer to move to a key, then press and release. He even created a G-code file which would press every one of the 10,000 4 key pin combinations.
A file this large was a bit unwieldy though, so [David] also created a python script which will do the same thing â€” outputting the G-code and coordinates to brute force any 4 pin keypad.Â While a printer is quite a bit slower than Hak5â€™s own USBÂ Rubber Ducky device (which acts as an automated keyboard), it will successfully brute force a password. Although most phones these days do limit the number of password attempts a user gets.
[David] admits this is probably useless in a clandestine/hacking application, but the video is still a great introduction to G-code and using 3D printers for non-printing functions.

This refurbished product has been professionally inspected and repaired. It contains all parts and accessories, but may show signs of wear. It is guaranteed to work like new, but may not come in the original packaging. If you’re ready to take your ideas and designs from paper or CAD file to the next level, the Monoprice MAKER SELECT 3D Printer is the perfect starter solution for your needs! Unlike kit-based printers, which require a certain level of knowledge, experience, and time to assemble, the MAKER SELECT 3D Printer is assembled using only 6 screws and includes everything you need to begin printing right out of the box. It has the ability to print any type of 3D filament and has a price point lower than most DIY kits, making it the best in class choice for your 3D printing needs. Preloaded with Printable 3D Models Includes Sample PLA Filament Ready to Print in 10 Minutes! Print Now: Unlike DIY kits, this printer comes almost fully assembled, requiring just 4 screws to secure the frame to the base and 2 screws to attach the filament holder. Additionally, the printer comes with everything you need, including sample PLA filament and a microSD card with sample 3D model files, ready to print! Compatible Software: With the ability to use both open-source and commercial software, such as Cura, Repetier, or Simplify 3D, the MAKER SELECT 3D Printer is compatible with Windows®, Mac® OS X®, and Linux. Large Volume: The large 8″ x 8″ build plate and generous 7″ vertical spacing means that you can print larger, more complex models. At less than the price of new gaming console, give the gift of learning and creativity this year! Maker Select 3D
