How to spy WhatsApp Messenger on Nokia, iPhone & Android

WhatsApp is a cross-platform messing application used by smartphones. It allows users to communicate instant messages and share media via 3G or WiFi with other users on the platform. Back in may 2011 WhatsApp had a security breach when hackers realized that messages were being transmitted unencrypted via plain text which left accounts open for hi-jacking. WhatsApp finally released a security update for this problem and the system became locked down.

In this article i will talk about alternative methods of hi-jacking WhatsApp messages and other protocols using a variety of methods.

The first hack im going to talk about will spoof WhatsApp and have it think you are somebody else allowing you to communicate under an alternative name. This hack works by tricking the WhatsApp Verification Servers by sending a spoofed request for an authorisation code intended for an alternative phone. This method is also known to work on several other IM applications based on iOS, Symbian & Android devices.

SPY 1

Install WhatsApp on your device
WhatsApp now starts a counter where it sends a verification message to its servers. If this verification fails after a specific time then WhatsApp offers alternative methods of verification. A message can be blocked by changing the message center number or pushing the phone into Airplane mode.
WhatsApp now offers an alternative method of verification
Choose verify through SMS and fill in your email address. Once you click to send the SMS click cancel to terminate the call for authorisation to the WhatsApp server.
Next we need to do some SMS-Spoofing
There are numerous ways of doing this for free. A quick google search will pull up a vast amount of services which can spoof email addresses.

If you are using an iPhone use the following details in the SMS spoofer application.

To: +447900347295
From: +(Country code)(mobile number)
Message: (your email address)

If you are using another device then check your outbox and copy the message details into the spoofer application and send the spoofed verification.

You will now receive messages intended for the spoofed number on your mobile device and you can communicate with people under the spoofed number.

SPY 2

The second attack I’m going to talk about is a little bit more professional. For users who can pull of MITM (Man in the Middle) Attacks this is a sure way to rake in data from a public network. I came across the script at the 0×80 blog so i I tried it on several public networks in Dublin (thanks to the karma code). The amount of data you can pull in from people sitting around you in a short amount of time is quite unreal. The code is written in Python so its nice and simple to work with and edit to make it work for similar chat applications.
You will also need to parse the traffic so check this link: http://www.secdev.org/projects/scapy/
Before you have a look at the code you may want to note that WhatsApp blurts out even more information for us to see. Doing a MITM Attack and peeking at the packets we can see that WhatsApp prints the mobile number and the name of the user your target is speaking with. This is important to note this because this data can be used for some social engineering (calling the person to pull more information from them) or by checking web resources such as Facebook or LinkedIn to find their address, email accounts, websites and what ever else your hunting for.
