Automotive Pen Testing Is Different in 2026
Automotive pen testing used to be very much an extra service. An OEM or manufacturer might test a vehicle in a very broad way i.e perhaps doing a general scan for known vulnerabilities. Today however, a modern vehicle runs tens of millions of lines of code across dozens of electronic control units, exposes attack surfaces over CAN, Ethernet, Bluetooth, Wi-Fi, cellular and UWB, ships with companion mobile apps and dealer tools, and connects to OEM cloud platforms that handle telematics, OTA updates and V2X services.
