What is WhatsApp?
We all know how this starts, from the beginning of course. Let’s learn how to hack a Whatsapp account. Whatsapp is a cross-platform instant messaging application that allows users to chat, text, share media, for instance, videos and voice messages with individuals or groups. Since its launch in 2009, it has quickly become the most globally popular messaging app with over 1.5 billion monthly active users. The app was created by Brian Acton and Jan Kuom, however, it is presently owned by Facebook.

Use QR code
This is a fraudulent attempt used by hackers to obtain sensitive information such as login details like usernames and passwords. Whatsapp phishing involves extracting the QR Code from Whatsapp Web then displaying it on a new page. If the victim 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 the QR code. The phishing program particularly uses node.js and socket.io for the website and selenium responsible for scripting browsers that communicate with the Whatsapp web client. To begin with, the program starts at Http and a socket.io server. If a new client connects to socket.io, the application will request a selenium instance to start a new browser and connect to web.whatsapp.com. Afterward, it will fetch the QR code data and send it to the client via the web socket connection. The client javascript then shows the QR code to the user. When the QR code gets scanned Whatsapp will authenticate the selenium controlled browser and store some tokens in the local storage and document cookie. Data is extracted then saved into a text file.

Moreover, hackers may also use keylogger applications to hack into a WhatsApp account. A keylogger is a software program that records every keystroke that a targeted user types into their mobile device. It does this by secretly monitoring the victim’s input and keeping a log of all keys that are pressed then saves the data for later use. In this case, when your target user opens WhatsApp in his or her phone, the keylogger collects all the information they type into the device and saves it for you. There are several types of keyloggers available only on the web including mSpy and iKey monitor.
