Federal cyber authorities just detailed a set of flaws in a heavy truck's brake computer, the unit that runs anti-lock braking, traction control, and stability.
Researchers found memory-corruption bugs and a hard-coded password inside it. In testing, a crafted signal sent over a legacy powerline data bus could knock out ABS, steering assist, the speedometer, and shifting. About 450,000 trucks were in scope.
The fix had already shipped, but quietly, as a safety recall with no security label attached.
That's the hard problem we work on: the computer inside the machine, not just the office network. When you think about vehicle security, does the brake controller make the list?
