The development of information and communication technologies directly contributes to the increasing number of connected vehicles on market, and their frequent use increases the number of crimes committed through unauthorized access to connected vehicles. Connected vehicles can contain key data that can help solve certain crimes such as car theft, identity theft, remote monitoring of an individual or solve traffic accidents involving or directly involved connected vehicles. Since the development of information and communication technologies directly contributes to the development of connected vehicles, analyzing potential points for unauthorized access to connected vehicles reduces the number of unauthorized access to connected vehicles using varius software and hardware tools. In this paper are analyzed potential points for unauthorized accesss to connected vehicles and their development in order to reduce the possibiliy of access to connected vehicles.The purpose of the paper is to present the possibility and features, i.e. limitations and potential points of intrusion into the systems of connected vehicles through which persons with unauthorized access obtain material or other benefits. The aim of the research is to present the concept of connected vehicles, the architecture and communication technologies of connected vehicles and their weaknesses. The paper was created by analyzing existing relevant literature on the topic, that is, an analysis of secondary literature, scientific articles and books was carried out using the Internet.
