WhatsApp

WhatsApp may have this year followed iMessage’s lead in adopting end-to-end encryption for its messages, but a security researcher says that both still have a security flaw that can allow deleted messages to be recovered – either from the device, or remotely from iCloud backups.

Jonathan Zdziarski found the flaw in the current version of WhatsApp.

The latest version of the app tested leaves forensic trace of all of your chats, even after you’ve deleted, cleared, or archived them… even if you ‘Clear All Chats.’ In fact, the only way to get rid of them appears to be to delete the app entirely.

Zdziarski says that data was left behind no matter what deletion method was used: archiving, clearing or deleting threads – and he suggests that the same flaw is present in iMessages …

Popular messaging service WhatsApp has today announced its first desktop client for Mac OS X. The launch of a desktop Mac client comes a few months after the Facebook-owned service launched a web interface and a month after it rolled out end-to-end encryption for all communication.

Although the battle over encryption between the FBI and Apple has currently subsided, the issue of privacy and security in technology continues. Today, WhatsApp is announcing that all messages, photos, phone calls and videos sent over its messaging app will be encrypted end-to-end. This means that no one can access any communications apart from the people in the conversation. This means if WhatsApp is subpoenaed by government for information, WhatsApp will not be able to help them as it simply cannot help them.

Civil rights organizations have expressed strong support for Apple’s resistance to a court order instructing it to create special firmware that would allow the FBI to break into an iPhone – with tech companies doing the same, albeit in a weaker fashion.

The Electronic Frontier Foundation (EFF) posted a statement in which it said that it applauded Apple for standing up for the rights of its customers, and would be making its views known to the court.

Essentially, the government is asking Apple to create a master key so that it can open a single phone. And once that master key is created, we’re certain that our government will ask for it again and again, for other phones, and turn this power against any software or device that has the audacity to offer strong security […]

EFF applauds Apple for standing up for real security and the rights of its customers. We have been fighting to protect encryption, and stop backdoors, for over 20 years. That’s why EFF plans to file an amicus brief in support of Apple’s position.

The Verge notes similar support from both the American Civil Liberties Union (ACLU) and Amnesty International …

Today, WhatsApp has announced a pretty major shift in its business model. The popular chat client is going completely free. Facebook-owned WhatsApp used to run on a trial model: users could use the app for free for a year. Subsequent years would cost $0.99 cents each. The paid model notably made WhatsApp stand out from the crowd, as almost every other social networking is free to use from the customer perspective. Although WhatsApp will stop charging customers from today, it will take a few weeks for the payment UI in apps to go away as app updates roll out to the store.

WhatsApp says although a 0.99 cent charge is not onerous, it prevented growth as a lot of customers do not have access to credit cards. This is its major motivation for taking out the annual revenue model. Naturally, users of WhatsApp will wonder how the application plans to monetize going forward ….

The highly popular WhatsApp messaging service owned by Facebook appears to be adding a new feature that allows iPhone users to chat in the browser using a web app. The feature is called WhatsApp Web and became available on various platforms including Android and Windows Phone earlier this year, but the feature was absent for iPhone users at the time “due to Apple platform limitations.” Using the chat service on the web requires running WhatsApp on a corresponding smartphone.

For several months we’ve followed the U.S. government’s attempts to work around encryption in chat apps, even taking the hyperbole to an illogical extreme at one point, but we haven’t yet seen similar threats from other nations… or at least, we hadn’t until today.

British prime minister David Cameron said today that unless the government is given backdoor access to encrypted messaging services, he’s just going to outlaw them:

Although this isn’t an actual update to the app, WhatsApp is now sporting a nifty new feature that—although small—might make a big difference in how users of the messaging app stay in touch with their friends. The Facebook-owned app, which would previously show double check marks if a sent message had been received, now goes one step further and turns those check marks blue if the message has been read.

The latest update to the popular, Facebook-owned WhatsApp Messenger app for iPhone hit the App Store with a long list of new features for users including the ability to share slow-mo videos from the iPhone 5s and trim clips down right in the app without having to edit the video in the Photos app.

Chatting with photos also received improvements with the ability to add captions and snap and share photos even faster added. Improvements and changes to location sharing, app wallpapers, and new notification tones are included. The latest version also allows users to move chat logs and contact groups away to an archive. Complete list of changes below…

Yes, another secure and ephemeral messaging app. There’s Wickr, Snapchat, Confide, so what makes Wiper Messenger different? I’ve had the chance to play around with the new free chatting app on iOS, and it seems to act as a fusion of WhatsApp, Snapchat, and Wickr. The app prompts you for your email address or phone number in order to create your account, and then you are brought to a fairly simple interface with three tabs across the bottom: Chats, Contacts, and More. Let’s go tab-by-tab:

A few years ago, Skype was the rockstar of the messaging world, but now with smartphones and mobile messaging apps like WhatsApp, Facebook Messenger, and iMessage, Skype’s iPhone feature-set and application have begun to stagnate. However, the Skype development team has not been standing still. The Microsoft-owned company is revealing today that it is nearing the launch of a completely revamped Skype application for the iPhone and iPod touch. I met with lead Skype designer Guilherme Schneider last week for an exclusive preview and an interview regarding the new software, and the application certainly seems impressive…
