Dear Sentinels

Hi and welcome! Chomping at the bit to start reading, well I shan't stand in your way ☺. First we will look at digital communication privacy and security. Tips and tricks and all that jazz, then well turn to the academic article.

In this weeks academic article we are returning to WhatsApp, again. A University of Vienna team did two studies: “Careless Whisper: Exploiting Silent Delivery Receipts to Monitor Users on Mobile Instant Messengers” and “Prekey Pogo: Investigating Security and Privacy Issues in WhatsApp's Handshake Mechanism”. In both these studies they found serous cracks, but we will focus of the first article in this newsletter.

But first, though, let's return to news from the web.
