Meta fixes easily bypassed WhatsApp ‘View Once’ Privacy Feature.

A privacy flaw in WhatsApp, an instant messenger with over 2 billion users worldwide, is being exploited by attackers to bypass the app's "View once" feature and view messages again.

The Zengo X Research Team found that Meta implemented this feature in what the researchers described as a "neglectful manner," allowing attackers to easily save and share copies of "View once" messages.

"We had responsibly disclosed our findings to Meta, but when we realized the issue is already exploited in the wild, we decided to make it public to protect the privacy of WhatsApp's users," Zengo's CTO Tal Be'ery said.

#CyberSecurity #WhatsApp #Privacy #ViewOnce: "Tal Be’ery, a security researcher who has been researching WhatsApp privacy issues for several months, recently discovered the bug. On Monday, Be’ery published a blog post detailing his findings.

Be’ery provided TechCrunch with a live demo of the bug last week, in which he showed he was able to capture and save a copy of a picture that TechCrunch sent as “View Once,” while he was using WhatsApp on the web.

“The only thing that is worse than no privacy, is a false sense of privacy in which users are led to believe some forms of communication are private when in fact they are not,” said Be’ery, who is the CTO and co-founder of crypto wallet Zengo, in his blog post. “Currently, WhatsApp’s ‘View Once’ is a blunt form of false privacy and should either be thoroughly fixed or abandoned,” wrote Be’ery."

I just learned of the biggest #bullshit feature I heard of: "view once" images in #WhatsApp. The idea is that if you send an image and select the "view once" option, the receiver may only "view it once". After that, it's deleted. And they claim it "prevents screenshots". How? I have no idea.

It doesn't matter because the whole concept is bullshit, of course.

WhatsApp Adds Snapchat-Like, View Once, Disappearing Photos

Facebook's WhatsApp chat application is adding a feature that was initially popularized by Snapchat: view once, disappearing photos and videos. The app is rolling out support for the feature this week.

Facebook says that even though photos and videos have only grown in importance for most people, it doesn't believe that everything shared needs to have a permanent digital record. In addition to the need for some level of privacy inherent in some photos, Facebook also says that not every photo taken of every event needs to take up space on a smartphone's camera roll.

To that end, Facebook is adding new "View Once" photos and videos to WhatsApp which will disappear from the chat once they have been opened, which the company says will give users more control over their privacy. View Once photos will be clearly marked with a new "one-time" icon.

After the photo or video has been viewed, the message will appear as "opened" to, as Facebook explains it, avoid any confusion about what was happening in the chat at the time.

Any photo or video sent in as "view once" will not be saved in the recipient's Photos or Gallery, and once the photo has been viewed it won't be viewable again. That media also cannot be forwarded, saved, starred, or shared, and a sender can only see if a recipient has opened a view one photo or video if they have read receipts turned on. If a recipient doesn't open the photo or video within two weeks of it being sent, WhatApp automatically expires it from the chat and it will not be viewable.

As was the case with Snapchat, WhatsApp's view once photos aren't protected against screenshotting or screen recording the media before it disappears, and senders won't be notified if someone takes a screenshot or screen recording.

Facebook says that as is the case with all messages sent on WhatsApp, View Once media is protected by end-to-end encryption so even WhatsApp can't see them. That said, Facebook has a sordid history when it comes to privacy that dates back as far as 2006. Most recently, Facebook chose not to notify users if they were affected by the massive data breach that affected over half a billion people.
