How to Hack Phone Network to Spoof the Number


This article is for learning purpose ONLY!

The Beginning of Everything!

Phreaking was the first type of modern hacking, performed when personal computers did not even exist and telephony was analog.

The first Phreakers became the first Hackers and gave us everything we have today in terms of communication hacking.

Phreaking is a slang term coined to describe the activity of a culture of people who study, experiment with, or explore telecommunication systems, such as equipment and systems connected to public telephone networks. The term phreak is a sensational spelling of the word freak with the ph- from phone, and may also refer to the use of various audio frequencies to manipulate a phone system. Phreak, phreaker, or phone phreak are names used for and by individuals who participate in phreaking.

What is Spoof?

Spoof is a technique of “forging” … in this case forging a phone number…

But what is that for?

For everything! If you don’t understand this you are in the wrong profession!

But if you are a dumb lammer from Kali and Offensive Security i will help you understand.

Let’s imagine that there is a security company called OffSecDUMBS, if you want to attack one of they customers you can Spoof the number of that company and call the customer, use social engineering and get everything you want!

After all, why wouldn’t the client trust a call “coming straight” from the office of the security company he hired?

Social engineering is the key! There are millions of possibilities and hundreds of methods!

Phreaking nowadays

Phreaking has evolved a lot but has become less and less known, but nowadays there are more things we can do related to Phreaking!

  1. Free Calls.
  2. Free Internet.
  3. Listen Calls.
  4. Spoof numbers.


Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS).

How to Spoof a Phone Number?

For that we will need three things:

  1. An Android Smartphone
  2. A VoIP Gateway App
  3. The PHREAK NUMBER App (developed by me)

What is a VoIP Gateway? Any application that can make VoIP calls (Thousands on PlayStore)… I like TalkU.

Hack TalkU

How the Hack works?

The first step is creating and setup a account on TalkU, the application will link your real phone number in the calls as all others VoIP gateway.

Don’t worry about that because using the PHREAK NUMBER App we will be able to change it…

Now install the PHREAK NUMBER App, open and give Root permission to it.

In the first look the application appear to be simple but it is not!

Now you need press the button “Copy FILES” that will copy the necessary files…

When the files copy is done you will see the screen like this:

Now you are able to see the “Actual Phone NUMBER”, your “TalkU UserID” (never show this.) and the CIPHER in the database.

The next step is type the number that you want to Spoof in the TextBox… let’s put a number that don’t exist only to test if the gateway allows it.

I will use the number “5511912345678”, type it and press the button “CHANGE”

Now you can see in the logs that the number has been changed, like the CIPHER too.

Ok, at this point everything is perfect so let’s press the button “HACK” who will apply all these new settings to the TalkU gateway.

So, as we can see the HACK is complete and we need to test our new Spoofed phone number.

Open the TalkU app and try to make a call to a number that you have and let’s see the Caller-ID.

I’ll try call The Cracker Technology number…

We can see in the TalkU app the message: “Call From: 11912345678.”

This is what appear in the device who receives the call:
