The open-source project BusKill has presented a working prototype for a 3D-printed kill cord. The so-called BusKill serves as a kind of emergency stop switch for laptops.
The USB cable with magnetic disconnect attaches to the user. When disconnected, the screen is locked or the computer is shut down to protect the data. Previously, the cables were manufactured commercially, but now months of work have gone into developing a version that can be made with a 3D printer.
According to the creators, this allows for easier verifiability and customization of the kill cords. Some 3D-printed components such as housing parts, a bracket and magnets were used to prove the prototype’s functionality. The developers see great potential in the self-printed BusKill to increase data security for vulnerable individuals.
Currently, the makers are still working on improvements to make the cables practical. Adaptations for a more stable connection and larger magnets are planned. Nevertheless, the prototype presented has already demonstrated the principle functionality of the concept.
