Show notes

Even with encryption and 2FA, if someone steals your logged-in laptop, you're compromised. Michael Altfield created Buskill - an open source USB "dead man switch" - to solve this analog attack vector. In this interview, you’ll hear about the real incidents that inspired it, the advocacy work that fueled it, and the collaborative engineering efforts that turned it into a practical tool for protecting sensitive data.
