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 — 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.

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.

📡 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
