History
2009–2014
WhatsApp was founded in February 2009 by Brian Acton and Jan Koum, former employees of2014–2015
On February 19, 2014, one year after a venture capital financing round at a $1.5 billion valuation, Facebook, Inc. (now Meta Platforms) announced it was acquiring WhatsApp for US$19 billion, its largest acquisition to date. At the time, it was the largest acquisition of a venture-capital-backed company in history. Sequoia Capital received an approximate 5,000% return on its initial investment. Facebook, which was advised by Allen & Co, paid $4 billion in cash, $12 billion in Facebook shares, and, advised byThe idea, he said, is to develop a group of basic internet services that would be free of charge to use – 'a 911 for the internet.' These could be a social networking service like Facebook, a messaging service, maybe search and other things like weather. Providing a bundle of these free of charge to users will work like a gateway drug of sorts – users who may be able to afford data services and phones these days just don't see the point of why they would pay for those data services. This would give them some context for why they are important, and that will lead them to pay for more services like this – or so the hope goes.Three days after announcing the Facebook purchase, Koum said they were working to introduce voice calls. He also said that new mobile phones would be sold in Germany with the WhatsApp brand, and that their ultimate goal was to be on all
2016–2019
On January 18, 2016, WhatsApp's co-founder Jan Koum announced that it would no longer charge users a $1 annual subscription fee, in an effort to remove a barrier faced by users without payment cards. He also said that the app would not display any third-party ads, and that it would have new features such as the ability to communicate with businesses. By June 2016, the company's blog reported more than 100 million voice calls per day were being placed on WhatsApp. On November 10, 2016, WhatsApp launched a beta version of two-factor authentication for Android users, which allowed them to use their email addresses for further protection. Also in November 2016, Facebook ceased collecting WhatsApp data for advertising in Europe. Later that month,Since 2020
In early 2020, WhatsApp launched its "dark mode" for iPhone and Android devices – a new design consisting of a darker palette. In March, WhatsApp partnered with thePlatform support
After months at beta stage, the official first release of WhatsApp for iOS launched in November 2009. In January 2010, support for BlackBerry smartphones was added; and subsequently for Symbian OS in May 2010, and for Android OS in August 2010. In August 2011, a beta forWhatsApp Web
WhatsApp was officially made available for PCs through a web client, under the name WhatsApp Web, in late January 2015 through an announcement made by Koum on his Facebook page: "Our web client is simply an extension of your phone: the web browser mirrors conversations and messages from your mobile device—this means all of your messages still live on your phone". As of January 21, 2015, the desktop version was only available to Android, BlackBerry, and Windows Phone users. Later on, it also added support for iOS, Nokia Series 40, and Nokia S60 (Symbian). Previously the WhatsApp user's handset had to be connected to the Internet for the browser application to function but as of an update in October 2021 that is no longer the case. All major desktop browsers are supported except forMicrosoft Windows and Mac
On May 10, 2016, the messaging service was introduced for both Microsoft Windows andApple iPad
As of May 2022, WhatsApp does not run on the iPad. iPad users searching for WhatsApp are shown numerous third-party clients. Several top results have names and logos resembling WhatsApp itself, and some users do not realize they are using a third-party client. Per WhatsApp's policy, using third-party clients can result in the account getting permanently banned. In a 2022 interview with ''Technical

s. On November 14, 2016, WhatsApp added a video calling feature for users across Android, iPhone, and Windows Phone devices.
In November 2017, WhatsApp released a new feature that would let its users delete messages sent by mistake within a time frame of 7 minutes.
Multimedia messages are sent by uploading the image, audio or video to be sent to an HTTP server and then sending a link to the content along with its Base64 encoded thumbnail (if applicable).
WhatsApp follows a " store and forward" mechanism for exchanging messages between two users. When a user sends a message, it first travels to the WhatsApp server where it is stored. Then the server repeatedly requests the receiver to acknowledge receipt of the message. As soon as the message is acknowledged, the server drops the message; it is no longer available in the database of the server. The WhatsApp server keeps the message only for 30 days in its database when it is not delivered (when the receiver is not active on WhatsApp for 30 days).
End-to-end encryption
On November 18, 2014, Open Whisper Systems

announced a partnership with WhatsApp to provide end-to-end encryption by incorporating the encryption protocol used in Signal into each WhatsApp client platform. Open Whisper Systems said that they had already incorporated the protocol into the latest WhatsApp client for Android, and that support for other clients, group/media messages, and key verification would be coming soon after. WhatsApp confirmed the partnership to reporters, but there was no announcement or documentation about the encryption feature on the official website, and further requests for comment were declined. In April 2015, German magazine ''Heise Security

They expressed the concern that regular WhatsApp users still could not tell the difference between end-to-end encrypted messages and regular messages.
On April 5, 2016, WhatsApp and Open Whisper Systems announced that they had finished adding end-to-end encryption to "every form of communication" on WhatsApp, and that users could now verify each other's keys. Users were also given the option to enable a trust on first use mechanism in order to be notified if a correspondent's key changes. According to a white paper

Facebook has stated that Novi would require a government-issued ID for verification and the wallet app would have fraud protection.
Meta ended its Novi project on September 1, 2022.
Controversies and criticism
Misinformation
WhatsApp has repeatedly imposed limits on message forwarding in response to the spread of misinformation in countries such as India and Australia. The measure, first introduced in 2018 to combat spam, was expanded and remained active in 2021. WhatsApp has stated the forwarding limits have helped to curb the spread of misinformation regarding COVID-19.
Murders in India

2018 elections in Brazil
In an investigation on the use of social media in politics, it was found that WhatsApp was being abused for the spread of fake news in the 2018 presidential elections in Brazil. Furthermore, it has been reported that US$3 million has been spent in illegal off-the-books contributions related to this practice.
Researchers and journalists have called on WhatsApp parent company, Facebook, to adopt measures similar to those adopted in India and restrict the spread of hoaxes and fake news.
Security and privacy
WhatsApp was initially criticized for its lack of encryption, sending information as plaintext
In cryptography, plaintext usually means unencrypted information pending input into cryptographic algorithms, usually encryption algorithms. This usually refers to data that is transmitted or stored unencrypted.
Overview
With the advent of comp ...
. Encryption was first added in May 2012. End-to-end encryption was only fully implemented in April 2016 after a two-year process. , it is known that WhatsApp makes extensive use of outside contractors and artificial intelligence systems to examine user messages, images and videos; and turns over to law enforcement metadata including critical account and location information.
In 2016, WhatsApp was widely praised for the addition of end-to-end encryption and earned a 6 out of 7 points on the Electronic Frontier Foundation's "Secure Messaging Scorecard". WhatsApp was criticized by security researchers and the Electronic Frontier Foundation for using backups that are not covered by end-to-end encryption and allow messages to be accessed by third-parties.
In May 2019, a security vulnerability in WhatsApp was found and fixed that allowed a remote person to install spyware by making a call which did not need to be answered.
In September 2019, WhatsApp was criticized for its implementation of a 'delete for everyone' feature. iOS users can elect to save media to their camera roll automatically. When a user deletes media for everyone, WhatsApp does not delete images saved in the iOS camera roll and so those users are able to keep the images. WhatsApp released a statement saying that "the feature is working properly," and that images stored in the camera roll cannot be deleted due to Apple's security layers.
In November 2019, WhatsApp released a new privacy feature that let users decide who can add them to groups.
In December 2019, WhatsApp confirmed a security flaw that would allow hackers to use a malicious GIF image file to gain access to the recipient's data. When the recipient opened the gallery within WhatsApp, even if not sending the malicious image, the hack is triggered and the device and its contents become vulnerable. The flaw was patched and users were encouraged to update WhatsApp.
On December 17, 2019, WhatsApp fixed a security flaw that allowed cyber attackers to repeatedly crash the messaging application for all members of group chat, which could only be fixed by forcing the complete uninstall and reinstall of the app. The bug was discovered by Check Point

in August 2019 and reported to WhatsApp. It was fixed in version 2.19.246 onwards.
For security purposes, since February 1, 2020, WhatsApp has been made unavailable on smartphones using legacy operating systems like Android 2.3.7 or older and iPhone iOS 8 or older that are no longer updated by their providers.

access to private messages was included in the anti-trust case against the latter. As the complaint is heavily redacted due to being an ongoing case, it doesn't disclose whether this alleged tampering with the app's end-to-end encryption or simply Google accessing user backups.
In January 2021, WhatsApp announced an update to their Privacy Policy which stated that WhatsApp would share user data with Facebook and its "family of companies" beginning February 2021. Previously, users could opt-out of such data sharing, but the new policy removed this option. The new Privacy Policy would not apply within the EU, as it is illegal under the GDPR. Facebook and WhatsApp were widely criticized for this move. The enforcement of the privacy policy was postponed from February 8 to May 15, 2021, but WhatsApp announced they have no plans to limit the functionality of the app for those who don't approve the new terms or to give them persistent reminders to do so.
On October 15, 2021, WhatsApp announced that it would begin offering an end-to-end encryption service for chat backups, meaning no third party (including both WhatsApp and the cloud storage vendor) will have access to a user's information. This new encryption feature adds an additional layer of protection to chat backups stored either on Apple iCloud or Google Drive.

In January 2022, an unsealed surveillance application revealed that WhatsApp started tracking 7 users from China and Macau in November 2021, based on a request from the DEA investigators. The app collected data on who the users contacted and how often, as well as when and how they were using the app. This is reportedly not a singular occurrence as federal agencies can use the Electronic Communications Privacy Act to covertly track users without submitting any probable cause or linking a user's number to their identity.
At the beginning of 2022, it was revealed that San Diego-based startup Boldend had developed tools to hack WhatsApp's encryption, gaining access to user data, at some point since the startup's inception in 2017. The vulnerability was reportedly patched in January 2021. Boldend is financed, in part, by Peter Thiel, a notable investor in Facebook.
In September 2022, a critical security issue in WhatsApp Android's video call feature was reported. The integer overflow bug resulted in malicious users being able to take full control of the victim's application once a video call between two WhatsApp users was established. The issue was patched on the day it was officially reported.

There are numerous ongoing scams on WhatsApp that let hackers spread viruses or malware. In May 2016, some WhatsApp users were reported to have been tricked into downloading a third-party application called ''WhatsApp Gold'', which was part of a scam that infected the users' phones with malware. A message that promises to allow access to their WhatsApp friends' conversations, or their contact lists, has become the most popular hit against anyone who uses the application in Brazil. Clicking on the message actually sends paid text messages. Since December 2016, more than 1.5 million people have clicked and lost money.
