The rapid development of intelligent networked vehicles has also raised cyber‐security problems, and vehicle cyber‐security has become an important part of national security. In order to improve the cyber‐security level of intelligent networked vehicles, this paper conducts cyber‐security risk analysis for several in‐vehicle network equipment with high installation rates in intelligent networked vehicles. Mainly carry out the following aspects: firstly, conduct research on the attack path, attack method and damage caused by security risks; secondly, carry out test verification, and conduct real vehicle tests on the security risks existing in in‐vehicle network equipment. This paper is of great significance for guiding the development of vehicle network equipment protection and improving its cyber‐security level.
