Graham Cluley reports:

WhatsApp likes to brag about its end-to-end encryption, but researchers from Germany’s Ruhr University Bochum have discovered a flaw that could allow unwanted eyes to spy upon your private group chats.

In a technical research paper that explores the end-to-end security of three different secure messaging apps capable of allowing “private” group chats, researchers found the most serious shortcomings in the immensely popular WhatsApp platform.

The research paper, presented at the Real World Crypto security conference in Switzerland, describes how it would be possible for a complete stranger to add themselves to an encrypted WhatsApp group chat. Although past messages sent to the group would not be visible to the intruder, they could receive future messages.

  1. I was just doing a Google search on what’s app users looking up non contact users and harassing them with sexual comments.

    This literally just happened to me yesterday. I was contacted by a random number on what’s app where I was being sent salacious messages with pictures of myself. It really freaked me out. I deactivated the app.

    I didn’t know if happened to other people on what’s app so I did a quick Google on this came. The search brought me to your Aug 26 2016 blog. I was unable to leave a comment.

    Have you heard about this kind of incidents on what’s app? What happened to me was not okay. I don’t want someone else to have to go through something like that

  2. Also I got this pop up after I submitted my comment that I am currently browsing.
    What does that mean on your site?

  3. What popup did you get? There’s no popup from my site when people submit comments.

  4. I dont know if this screen shot came up. You may find an email about this as well.

    What does that mean about browsing on your site? Do readers or commenters need to be concerned about this?
