With the bug in the chat, you can add new users without administrator consent.
The German cryptographers had discovered a way to sneak in group chats WhatsApp, which are protected through encryption.
It is reported that with the bug, the attacker gains the ability to add to the chat rooms new users without the knowledge of the moderator. In the end, the server automatically provides the secret keys to a new participant, he gets full access to messages in the conversation.
“This nuance completely eliminates the benefits of end-to-end encryption, as the addition of new members correspondence should be protected”, – said the expert of the Ruhr University Paul Ressler.
To protect yourself, experts suggest to only use private messages instead of group chat.
