Tom Uren and James Wilson talk about moves from several European governments to ditch Signal and set up their own encrypted messaging systems for internal government use. These efforts are motivated by concerns about phishing and sovereignty, but the solutions being adopted are imperfect and will come with their own set of problems.

They also talk about Fast16 malware. We are only now learning about the second arm of a mid-2000s campaign to delay Iran’s nuclear weapons program that included the infamous Stuxnet worm.
