I am writing this letter after more than a month. There are too many things I want to write about, but, I am going to keep this one very sort, and focused on attacks over mobile phones. From last night, the biggest news on the Internet is about crown prince of Saudi Arabia sending a malware to the richest person of the world, Jeff Bezos.

The story is on almost every news site. The incident happened using some kind of 0day attack via WhatsApp, and this is not the first time. CitizenLab records more than 100 new abuse cases.
