We understand that hackers look for weaknesses in networks to manipulate or take data, but understanding the ways that vehicles can also be accessed either remotely or physically can be a bit surprising.
Today's guest is Derrick Thiecke. Derrick works as an Embedded Systems Security Tester in the automotive industry where he found himself after spending over a decade in the corporate IT world. When Derrick isn't data dumping ROM chips, scouring through vehicle log data, or fuzzing CAN networks, he can be found as a brief blur passing by you on the highway.
Show Notes:
- [0:58] - Derrick shares his background and current role as a security tester for automotive controllers and devices.
- [3:30] - There are differences between vehicle networks and home networks. The main network for vehicles is CAN bus.
- [5:12] - Because it is a bussed network, Derrick explains how all devices on the network can access all the data.
- [6:50] - Previously, you had to have physical access to hack a car, but not anymore.
- [8:19] - Derrick describes how his own vehicle accesses data on a network.
- [9:56] - The implementation of standards has changed the way vehicles are serviced.
- [11:18] - Safety critical features are isolated, but some things can still be accessed that can be harmful.
- [12:29] - There was an event in 2015 where a parking feature was hacked while the vehicle was in motion.
- [13:59] - There are ways to communicate with and change the fuel mapping over CAN bus, but there is usually a physical component required.
- [16:07] - Derrick describes a scenario that creates a potential threat.
- [19:04] - The automotive industry typically sits about a decade behind in technology.
- [21:24] - Derrick lists some of the features in a vehicle that are connected to a network.
- [23:18] - The number of vehicle recalls due to software issues has increased since 2015, but the issues aren't growing.
- [25:01] - Movies depict vehicle hacking as possible disasters. Derrick shares his concerns.
- [26:44] - When ransomware became a problem, we had the same questions. The threat for the worst case scenario is plausible.
- [28:31] - Derrick describes the most concerning problem he has experienced as a tester.
- [30:59] - Different cars all use the same controllers, even those without the same features.
- [32:26] - There are devices that can unlock vehicles without the key or keyfob.
- [34:18] - When there is an issue with a computer, typically there is an update to solve it. That currently isn't the case for most vehicles.
- [35:41] - There are some updates that can happen remotely, but the catch-22 is that the wireless connection makes the vehicle susceptible to threats.
- [37:02] - There is a huge shortage of workforce in this industry.
- [38:41] - Derrick recommends the book The Car Hacker's Handbook if you are interested in this field.
