The interconnected reference for telecom protocols, architecture, and security.

[Telcom IQ @telcomiq]

Part 2 of our protocol reference covers the IP era — SIP, GTP-C, GTP-U, Diameter, and the 5G additions that came after. The threats didn’t go away. They evolved.

Part 2 — IP & Modern Protocols

4G didn’t just change how fast your phone downloads. It changed the entire signalling architecture underneath it.

New protocols, new attack surface.

Part 1 of our protocol reference covers the legacy signalling stack — SS7, MAP, CAMEL, SIGTRAN and ISUP. Each one shaped how global telephony works. Each one has a threat story worth knowing.

Part 1 — Legacy Signalling

Before 4G, before 5G, before IP — mobile networks ran on a stack of signalling protocols built for a different era.

Some of them are still running today. So are their vulnerabilities.

5G has better security than 4G. But the SEPP — the proxy guarding every 5G roaming connection — is only as strong as its configuration.

Not enough people are talking about this.

SIP powers most of the world's VoIP calls — but it's wide open to eavesdropping, session hijacking & toll fraud.

If your business runs on VoIP, this matters.

GTP-U carries your mobile data across 4G & 5G networks — but it's vulnerable to traffic interception, session manipulation & security bypass.

Ever heard of GTP-C? Attackers have.

This control plane protocol manages mobile data sessions across 4G & 5G — and it's wide open to session hijacking, fraud & DDoS attacks on core infrastructure.

SS7 gets the headlines — but Diameter has its own serious vulnerabilities.

The protocol powering 4G LTE networks can expose subscriber data, enable location tracking & disrupt services.

Telcos, enterprises, and security teams need to understand the risk — and what to do about it.

📡 Your phone calls and texts may be less secure than you think.

SS7 — the signalling protocol that underpins global mobile networks — was designed in the 1970s. It was built for a world where only a handful of trusted carriers had access. Today, that's no longer the case.

The result? A decades-old vulnerability that attackers can exploit to:
🔴 Intercept calls and SMS messages
🔴 Track device location in real time
🔴 Bypass SMS-based two-factor authentication
