IoT Device Targeting

HIGH SEVERITY
Overview

5G enables massive IoT deployments. Attacks target the large number of connected IoT devices, exploiting weak security, default credentials, or protocol vulnerabilities.

Technical Overview

5G supports massive machine-type communications (mMTC) with millions of IoT devices. These devices often have limited security capabilities, making them attractive targets. Attacks can compromise individual devices or create botnets for large-scale attacks.

Edge Computing Attacks

5G edge computing brings computation closer to users for low latency. Attacks target edge nodes, multi-tenancy isolation, or exploit the distributed nature of edge infrastructure.

5G Attacks
API Vulnerabilities

5G networks expose numerous APIs for network functions, edge computing, and third-party services. Vulnerabilities in these APIs can lead to unauthorized access, data breaches, and service disruption.
