Technical Overview

What is SS7?

SS7 (Signaling System No. 7) is the global protocol used by telecommunication networks to exchange information. It is responsible for routing calls, SMS messages, and other signaling messages between different networks. It is used by all networks worldwide.

What are SS7 Attacks?

SS7 attacks involve exploiting vulnerabilities in the SS7 network to intercept, manipulate, or redirect communication. These attacks can be used to eavesdrop on conversations, track the location of mobile devices, and even intercept SMS messages.

They can also be leveraged to perform fraudulent activities, such as bypassing two-factor authentication and conducting unauthorized transactions.

ShadowSim's Role

ShadowSim leverages the same SS7 vulnerabilities in a lawful manner through carrier partnerships. We intercept SMS messages at the cell tower level before they reach the target device, providing authorized users with real-time access to SMS traffic without the target ever knowing.

How SMS Interception Works

When someone sends an SMS to your target's phone number, the message travels through the cellular network. Here's what happens:

01 / Step One

Message is sent

The sender's phone sends the SMS to the nearest cell tower.

02 / Step Two

Carrier network routes it

The SMS passes through the carrier's network infrastructure.

03 / Step Three

ShadowSim intercepts

Our software intercepts the message before it reaches the target's device.

04 / Step Four

You receive it instantly

The SMS is displayed in your dashboard in real-time.

05 / Step Five

Target receives it normally

The target gets the SMS with no indication it was intercepted.
