Ah, 5G, what promising associations it evokes in our brains in these exciting times of change. Ultrafast speeds, lower latency, higher connection density, increased bandwidth: a beautiful new world lays ahead. However, just like any system that has been built on top of another system, certain weaknesses are being dragged from one stage to the other. As with any complex telecoms protocol, it contains some flaws that can make it easier for attackers to gain access to user data, commit fraud and cause denial-of-service incidents. Disastrous effects can be the result for millions of subscribers, resulting in loss of revenue and churn. Additionally, there is the potential for disrupting connected IoT networks, such as hospitals, city infrastructures or critical industries like energy production or agriculture.
