To be fair, this is the most extreme implementation of BusKill. TechCrunch reports that the full drive option is available only on Linux. For Windows and MacOS, the application can only lock your PC. Future options might let it shut down automatically, and thus leave one more layer of encryption between potential data thieves and their prize. BusKill began as an open-source Linux project, with the help of a magnet break-away cable (similar to the Magsafe charging cables seen on Macbooks). Fortunately, after the project became very popular, a Crowd Supply project created an entire package that included custom hardware and software to implement the security tool. An AC port and a downloaded app are all you need. Usefully, you can disable or remove the security, and with the push of a button. A recommended use case for BusKill. BusKill The project is designed for people who manage sensitive information and can get involved in espionage with the help of journalists, activists and traders. But because the matter of your paranoia does not mean nobody is going to be able to get you, and anyone security-conscious can buy a BusKill unit for 49-99 USD depending on the extras. Take my tip and you don’t use it anywhere near cats, dogs, children or even adults who are less than graceful. A tug on your arm may cause a lot of grief for you.
