About

Whatsapp is a carrier-free messaging app that allows phone-to-phone messaging over the Internet, creating a free method for text-message style communication internationally. The app, which is owned by Facebook, is the biggest messaging app in the world, with over 900 million users as of September 2015.

History

Founded in 2009 by two ex-Yahoo employees, WhatsApp was originally created as a status-showing app, and named due to its linguistic similarity to "What's Up?".^[3] When Apple released push notifications for the iPhone in June 2009, WhatsApp enabled them for status changes, and introduced a messaging feature; within a few months more than 250,000 people had downloaded the app.^[1] Later that year, after receiving a seed investment, WhatsApp introduced a version for Blackberry, which allowed Blackberry users and iPhone users to communicate for free via messaging internationally.

The company switched from a free structure to a $0.99/year plan to keep the system from growing too fast. By 2011, WhatsApp was usually found in the top 20 apps list in the iPhone app store. By February 2013, the app had more than 200 million users, and it had doubled that number by the end of 2013; as of September 2015, the app has over 900 million users.^[1] It is most popular in India, where it has over 65 million users, but people worldwide use it on both Android and Apple phones. In 2014, the company was acquired by Facebook for $19 billion. Many users disagreed with the acquisition, and moved their messaging to competing services like Line and Telegram after a service outage.^[4]

Features

WhatsApp allows anyone with the app to message anyone else with the app, which is common in messaging, but it also allows people with the app to message anyone with a cell phone number as well, but using the smartphone's wifi connection instead of its cell connection. This innovation freed the phone from international data and text-messaging fees, and made it easier for people to communicate by text messaging to their friends and family in other countries.^[5]

WhatsApp interfaces on iPhone and web.

In November 2014, WhatsApp introduced a feature called "Read Receipts," which showed other user if their message had been seen or not, but the feature annoyed many and they introduced a method of disabling it a week later.^[6] In January 2015, WhatsApp introduced VoIP calling, allowing people to use the app to make phone calls to people in other countries for a lower rate.

Malicious WhatsApp Clone

On November 3rd, 2017, Redditor ^[8] E_x_Lnc posted on the /r/Android subreddit a series of screenshots revealing two different WhatsApp apps being sold in the Android store. The images show the original "WhatsApp Messenger" app (shown below, left) and the fraudulent "Update WhatsApp Messenger." Within a week, the post received more than 600 points (91% upvoted) and 130 comments.

Later that day, another Redditor^[9] megared17 explained that that extra bytes, which "are a unicode space at the end," allowed the app to be registered under the name "WhatsApp Inc." Essentially, the makers of the fake app added several spaces at the end of the publisher name, "WhatsApp Inc."

Another Redditor,^[10] dextersgenius, responded to megared17 stating that the app is "an ad-loaded wrapper which has some code to download a second apk, also called 'whatsapp.apk.'" The "Update WhatsApp Messenger" installs ads and other software without the user's knowledge.

As of November 6th, the "Update WhatsApp Messenger" app has been downloaded more than one million times. Several news outlets covered the story, including BBC,^[11] Mashable,^[12] The Daily Dot^[13] and more.
