Open Source 5G Networks, Spoofing Attacks, and Proof-of-Concept Multi-Node Continuous Spectrum Analysis

Abstract

As 5G networks increase in popularity, so do their security concerns. This report will be focused primarily on 5G Spoofing Attacks and proposes a way to prevent this. This is done by taking advantage of the Global User Temporary Identifier (GUTI), Random Access Control, and other aspects of 5G specifications to create a connection to a User Equipment (UE) that would accept 5G data packets and hold them from an adversary gNB. The original plan for this project was to create a 5G network and design spoofing and targeted attacks; however, several issues with the OAI software prevented this plan from materializing. Because of this, the latter part of this project shifted its focus to creating a network of sensor nodes to collect data from 5G networks that would allow for further analysis
