WhatsApp will soon let you switch from voice to video calls

The vulnerabilities found in Threema and Signal are relatively harmless compared to the problems researchers found with WhatsApp, because of the relative ease with which new people can be inserted into private groups without any permission.

WhatsApp Messenger, which has made our lives easier and connected people like never before seems to be making headlines yet again.

A flaw in WhatsApp's group messaging protocol means that, despite its vaunted end-to-end (E2E) encryption, messages can still be read by unwanted eyes, researchers from Germany's Ruhr University Bochum have found.

"The confidentiality of the group is broken as soon as the uninvited member can obtain all the new messages and read them", Paul Rösler, on of the co-authors of the paper, told Wired. The flaw here is obvious: since the group management messages are not signed by the administrator, a malicious WhatsApp server can add any user it wants into the group.

Responding to the report, WhatsApp said, "We've looked at this issue carefully".

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. Also, if the attacker controls the server, he or she can block the messages sent by users who might question the new addition or warn others about it. "And if not, the value of encryption is very little". Facebook-owned chat company WhatsApp is testing a new feature that will allow one admin to remove the other one from the post of group admin.

In addition, Netanyahu will give an inaugural speech at the Raisina Dialogue and will preside the Indo-Israeli CEO forum in Delhi. Israel is a major weapons supplier to India, exporting an average of $1 billion of military equipment each year.

Have you ever been bombarded with hundreds of notifications from a WhatsApp group, and chose not to read any simply because there were tons of messages and a lot of them did not seem to matter to you? This is an obvious security concern as all the messages sent after the insertion of the new entity can be intercepted.

In every WhatsApp group, users see a special blue message when someone joins or leaves a group.

For additional security, users can easily verify the security code of other group members.

Hackers and spies could secretly eavesdrop on your private WhatsApp conversations, security researchers have claimed.

WhatsApp recently started testing another new group chat feature called Restricted Groups, which lets you force everyone else in your group to stop chatting. We say so as it is common for us to mute large groups that will result in skipping important conversations and messages. "If I hear there's end-to-end encryption for both groups and two-party communications, the means adding of new members should be protected against".
