- When we use WhatsApp and Signal, then there is a method to know, does the receiver read the message or not by seeing the double tick UI. Thus here we can send an malform message which send the device(using phone number) a message who’s message id doesn’t exist but this will send the person who sent the malform message status does the message viewed or not and we don’t even get the notification as the message id is invalid, by this they can track when we are active, which device we’re using and by tracking our suspicious closest circle they can also track are we talking with them
