Four years after Facebook Inc. bought WhatsApp for $22 billion, it is formally starting the messaging app on a new mission: bringing in revenue. WhatsApp on Wednesday detailed plans to sell advertisements and charge big companies that use its service to interact with customers, launching its first major revenue streams as growth at Facebook’s main app is starting to decelerate.

First, and this was pointed out by our tipster Nitin, is the fact that WhatsApp can re-download media that was deleted from the device's storage. I can't say how new (or old) this is. It's been years since I've deleted some WhatsApp media, but a friend did so several months ago and asked me how to get them back. The option wasn't there then. So the best I can guess is that it's relatively new-ish.

The Facebook CEO can’t be trusted.

Unlike Facebook and Instagram, WhatsApp has received little attention for its influence on voters. But in one Indian state, the messaging service became a prime election tool.

“It is time for me to move on... I’m taking some time off to do things I enjoy outside of technology, such as collecting rare air-cooled Porsches, working on my cars and playing ultimate frisbee,” WhatsApp co-founder, CEO and Facebook board member Jan Koum wrote today. The announcement followed shortly after The Washington Post reported that Koum would leave due to disagreements with Facebook management about...

A pioneering fingerprint technique used to convict a drugs gang from a WhatsApp message "is the future" of how police approach evidence to catch criminals.

In 2014, Facebook bought WhatsApp for $16 billion, making its co-founders — Jan Koum and Brian Acton — very wealthy men. Koum continues to lead the company, but Acton quit earlier this year to start his own foundation. And he isn’t done merely with WhatsApp — in a post on Twitter today, Acton told his followers to delete Facebook.

In the four or so years since it launched, end-to-end encrypted messaging app Signal has become the security community's gold standard for surveillance-resistant communications. Its creators have built an encryption protocol that companies from WhatsApp to Facebook Messenger to Skype have all added to their own products to offer truly private conversations to billions of people. And it's done so as a non-profit with, at any given moment, a tiny staff that includes just two or three full-time coders. Now imagine what it might accomplish with actual Silicon Valley money behind it.

As Cape Town braces for the day when it will run out of water, a campaign to donate water to its residents has become a social media phenomenon.

Afghanistan has ordered the suspension of WhatsApp and Telegram to resolve "technical problems", officials said Saturday, sparking outcry among social media users. Facebook-owned WhatsApp and Telegram are popular messaging apps among smartphone-using Afghans -- including Taliban and Islamic State jihadists. So far state-owned Salaam Network is the only internet provider to obey the order, which applies from November 1 to November 20, telecommunications ministry spokesman Najib Nangyalay told AFP.

Open door: Cumulative effect of missteps led the Guardian to overstate the potential impact on the security of users’ messaging

A thirty-strong group of security researchers have co-signed an open letter calling for the Guardian to retract a story it published last week that had claimed mobile messaging app WhatsApp contains a “backdoor”. “Unfortunately, your story was the equivalent of putting “VACCINES KILL PEOPLE” in a blaring headline over a poorly contextualized piece,” writes academic Zeynep Tufekci, who organized the open letter.

A security vulnerability that can be used to allow Facebook and others to intercept and read encrypted messages has been found within its WhatsApp messaging service. Facebook claims that no one can intercept WhatsApp messages, not even the company and its staff, ensuring privacy for its billion-plus users. But new research shows that the company could in fact read messages due to the way WhatsApp has implemented its end-to-end encryption protocol.

Messaging services such as WhatsApp, Facebook Messenger and Gmail will face tough new rules on the tracking of users under a revision to the ePrivacy Directive proposed by the European Commission on Tuesday. The new legislation seeks to reinforce the right to privacy and control of data for European citizens, with messaging, email and voice services – such as those provided by Facebook, Google and Microsoft – forced to guarantee the confidentiality of conversations and metadata around the time, place and other factors of those conversations.

WhatsApp retains and stores chat logs even after those chats have been deleted, according to a post today by iOS researcher Jonathan Zdziarski. Examining disk images taken from the most recent version of the app, Zdziarski found that the software retains and stores a forensic trace of the chat logs even after the chats have been deleted, creating a potential treasure trove of information for anyone with physical access to the device. The same data could also be recoverable through any remote backup systems in place.

A Brazilian judge ordered an indefinite blackout of the WhatsApp messaging service on Tuesday, only to be overturned within hours by the country's supreme court. First reported by O Globo, the order comes after temporary blackouts issued in December and May, both of which were overturned by higher courts in a matter of days. Unlike previous orders, today’s blackout had no set expiration period, and was intended to continue until the company complies with a previously issued request for WhatsApp messages related to an ongoing investigation.
