One of the most popular is called WhatsApp Sniffer, whose APK you can download from this same page, although we already told you that it is not worthwhile to waste your time.
The app that aims to break the encryption of WhatsApp. Obviously none of these apps is available on Google Play, first because they involve a violation of the user’s privacy and second because most of them are a fraud and do absolutely nothing of what they promise. So no one should be surprised that from time to time applications arise that promise to provide you with the necessary tools to spy on the conversations of friends and strangers, to know what is being told and stop being behind your back. And it does not escape that is possibly the largest communication channel of our time: instant messaging and its undisputed king, WhatsApp.
Since time immemorial man has managed and has invented mechanisms to spy on their peers and hear about other people’s conversations that do not even come.
