    German researchers have discovered a method of secretly infiltrating groups on WhatsApp, although it is not exactly easy. Security is one of the fundamental pillars of communication. Being able to talk safely without others reading our messages seems not to be possible on WhatsApp, at least as far as group conversations are concerned. Now we explain it to you!

    Spying on WhatsApp groups secretly is possible but not easy

    As Wired explains to us, at the World World Crypto conference in Zurich, Switzerland, a team of researchers from the German Ruhr University tried to test the security of three messaging applications. Signal, Threema and WhatsApp.

    All three have some security issues, although those of Signal and Threema don't seem very dangerous. Whatsapp; However; it appears to have serious security concerns. To be clear, the German research team stated that anyone who manages to sneak into WhatsApp's servers can self-invite themselves into any user group.

    WhatsApp by default encrypts all chats with a type of encryption known as end-to-end. This encryption ensures that even if our messages go through a server, only the sender and recipient of the message will be able to read them.

    In the case of groups, we have the guarantee that only the users of a group are able to read the messages. This premise falls upon the moment someone is able to join a group without problems.

    Despite the seriousness of the problem, we must keep in mind that this vulnerability can only be exploited by someone who manages to break into the company's servers. Company personnel, highly skilled hackers and government agents. 😉 This is a door that is always open… for them!

    The research team insisted that with certain techniques, it is possible that users of the conversation will not receive the message that the new user (in this case the spy) has read or deleted before them.

    Those at Wired contacted a WhatsApp spokesperson on the phone, who confirmed that the security hole exists, but if someone could sneak into their servers and join a group, all users would receive a notification that a new user has been invited. to the group, so all users would be aware of the attack.

    Although we are not always so vigilant!
