TelcoSec Talk: A Deep Dive

If you want a clear and honest look at how telecom networks were actually attacked in 2025, this session is for you. TelcoSec Talk: A Deep Dive into 2025 Attacks takes you inside the real incidents that kept operators awake this year, from long running infiltrations to large scale customer data compromises.

During this live technical walkthrough, you will see how attackers moved across roaming links, abused signalling protocols, exposed SIM keys, and took advantage of misconfigurations inside 4G and 5G cores. We will show you what really happened, why it worked, and what operators could have done to catch it earlier.

Our experts, El Mehdi Regragui and Kye Grundy, break down four major attacks step by step and explain the techniques, entry points, and behaviours that matter most for defenders. If you work in mobile network security, core operations, or regulatory oversight and you want practical insight instead of generic summaries, you will get real value from this deep dive.

By the end of the session you will have a clearer picture of today’s active threats, the gaps attackers consistently target, and the concrete actions that can help reduce exposure across SS7, Diameter, GTP, SIM authentication flows, and backend systems.
