Craig Smith (@OpenGarages) spoke with us about hacking the software in cars. His book is the Car Hackers Handbook. There is a 40% off coupon toward the end of the show. OpenGarages is Craig's site to improve and encourage hacking. Some tools he recommends for getting started are USB2CAN and CANTact. An older (shorter) version of the handbook is on OpenGarages. I Am The Cavalry (iamthecavalry.org) is an excellent site for learning more about security. CERT.org is also good. Theia Labs is Craig's company.
