Facebook, which owns WhatsApp, has denied the flaw is a problem. The firm's Chief Security Officer Alex Stamos wrote on Twitter that the bug is not effective because WhatsApp users are notified when new members join conversations. Once a person has infiltrated a conversation, everyone in the chat automatically shares secret keys with that user.
This means they have access to all future messages, but cannot view past ones. The researchers suggest that those seeking absolute privacy should stick to one-to-one chats or use a different encrypted messaging service. Experts found that anyone with control over WhatsApp's servers can add people to private group chats, including staff, hackers and governments who legally demand access.
But there is no [sic] a secret way into WhatsApp groups chats. He said that there are multiple ways to verify group chat members, adding that users are notified of anyone new joining, including those without permission. The news comes just months after WhatsApp's highly-anticipated 'Delete For Everyone' feature was found to have a major flaw.
Mr Stamos added that WhatsApp does not intend to fix the bug because it would means removing invite links, which millions of people use per day. The innovative November update allowed users to delete messages within seven minutes of sending them. While users were not able to see the message within WhatsApp after it was deleted, they could still see it in the notification log on Android devices.
Researchers found in November that deleted messages were actually still on the device, and could easily be accessed through the app's Settings.

In fact, many Jabber servers run Tor hidden services to make it so Tor users can connect without having to leave the Tor network at all. Off-the-Record OTR is an encryption protocol that can add end-to-end encryption to any chat service, including Jabber. In order to have an encrypted chat, both sides of the conversation need to use chat software that supports OTR. ChatSecure for Android has great built-in support for creating anonymous throw-away secret identity accounts.

Download and install Tor Browser. Open it, and load this article in that browser instead of the one you were using. There are hundreds of Jabber servers to choose from. You can find lists of some of the public Jabber servers here and here. Which should you choose? Still, you might want to pick one that you think is unlikely to hand over logs to your government, and that is happy with Tor users making secret identity accounts. The most common way that people create Jabber accounts is directly through their chat software.
Because of this, I recommend that you choose a Jabber server that lets you create a new account on their websites, so you can do it from Tor Browser instead of your chat program. Here are a few Jabber servers that you can create new accounts on using Tor Browser, chosen at random from the public lists: Ready to get started? Pick a Jabber server. Create a Jabber account using Tor Browser. Now keep note of the server you created it on, your username and your password, and move on to the next sections for Android or Mac OS X or Windows and Linux.
Make sure you know which Jabber server you created your account on and what your username and password are. Make sure Tor Browser is open. While Tor Browser is open, a Tor service will be running in the background on your computer. When you close Tor Browser, the Tor service stops running.
Go ahead and open Tor Browser and keep it open for the rest of this tutorial. With the Contacts window selected, click Adium in the menu bar at the top and choose Preferences.

Now switch back to the Account tab. Type your Jabber ID. Adium should now attempt to connect to your secret identity account over Tor. You are now anonymously connected to your secret identity account using Tor.

The next step is to set up an OTR encryption key. Each person who wishes to use OTR needs to generate their own key, which is a file that gets stored locally on the device you use for chatting. Each key has a unique string of characters called a fingerprint associated with it — no two keys share the same fingerprint.
With the Contacts window selected, click Adium in the menu bar and choose Preferences. Go to the Advanced tab, and click on Encryption in the left sidebar. Select your secret identity account and click the Generate button to generate a new encryption key. In this example, I just created a new OTR key for my pluto1 xmpp. If you want to have a private conversation with someone, tell them your Jabber username and server as well as your OTR fingerprint.
After they create an anonymous Jabber account and an OTR key, get them to tell you what their username, server and fingerprint are too. Once you start an encrypted conversation with them, you will be able to see their fingerprint and they will be able to see your fingerprint. If the fingerprint they gave you matches the fingerprint you see in Adium, you can mark that contact as trusted. And if the fingerprint you gave them matches the fingerprint they see in their chat program, they can mark you as trusted.

This step is confusing, but also important. They told me their Jabber account is pluto2 wtfismyip. First I select the Contacts window and then click the Contact menu bar at the top and choose Add Contact. Then I click the Add button to add them as a contact. First you need them to consent to let you see their status.
So now I need to wait for pluto2 to login and approve my contact request. Now all I need to do is double-click on their name to start chatting with them. Before it sent my message, Adium started a new OTR encrypted session. Does the fingerprint that pluto2 gave me match the fingerprint that I see in that box?
