FAQ

No. Even if an exact replica was inserted, BusKill will still be triggered if it's disconnected.

That's good! But it won't protect you if a thief snatch-and-runs with your laptop after you've authenticated.

The only way to defend against this sort of attack is by using a Dead Man Switch to detect that you've been replaced at the helm, such as BusKill.

Using a radio-based Dead Man Switch introduces complexity, delays, and an increased vector of attack. BusKill is a simple hardware kill cord and is therefore more secure than any wireless solution.
