P1 Security's mission is Securing Operators and Nation-states Critical Mobile Infrastructure to defend against cybersecurity threats and attacks

P1 Security

Physical exposure still creates real compromise paths in modern mobile networks. This live session shares red team lessons learned on how compromise chains can start with physical access and evolve into broader telecom impact, including how defenders can break the chain early with practical, measurable controls.

**What you will learn:**

*   Where physical exposure still matters in modern mobile networks
*   Typical escalation patterns from initial foothold toward sensitive environments
*   Visibility gaps that delay detection and inflate response time
*   Defensive priorities that reduce blast radius and improve evidence during investigations

**Speaker:**

Philippe Langlois, Founder and CEO

**Date and time:**

Thursday 5 February 2026

Physical to 5G Core Compromise

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.

**Exploring O-RAN Security**

**\[Webinar #10 – Thursday, July 3 | 16:00–17:00 CET]**

Open RAN (O-RAN) is rapidly gaining traction as a transformative approach to building mobile networks—bringing promises of cost efficiency, vendor interoperability, and innovation through open interfaces and disaggregated components. But while the benefits are clear, the security implications are far from fully understood.

In this technical webinar, P1 Security’s telecom security expert **Kye Grundy** explores the hidden risks and threat surfaces emerging from O-RAN deployments. We will cover real-world vulnerabilities affecting the O-DU, O-RU, and O-CU components, security gaps in interface protocols like E2 and A1, and how attackers may exploit orchestration layers and multi-vendor integration points.

You’ll also gain clarity on:

*   Common security misconfigurations in Open RAN deployments
*   The evolving threat landscape for disaggregated RAN architecture
*   Lessons learned from recent security assessments and testbeds
*   Recommendations for telecom operators and systems integrators looking to harden their O-RAN infrastructure

Whether you're involved in 5G rollouts, network security architecture, or vendor management, this session will help you understand how Open RAN security is reshaping the risk profile of mobile infrastructure—and what can be done to stay ahead of attackers.
