Subvert Trust Controls: UDS Security Access

Adversaries may exploit UDS Security Access in vehicle cybersecurity to gain unauthorized access to critical ECU services. This technique involves cracking the challenge and response mechanism used to unlock secure features. By reversing the challenge and response function, adversaries can extract the key and bypass the security measures in place.

This attack method allows adversaries to access and modify sensitive vehicle components, such as read/write memory, without proper authorization.
