On this week’s Cyber Security Brief podcast, we discuss our new research into the Elfin espionage group, which we have seen targeting multiple organisations in Saudi Arabia and the U.S. We also talk about one of the big stories of the last week – ASUS’ software update system being hijacked to send out malicious updates, as well as discussing the ongoing issue of insider threats, and some new research into how mobile apps could be compromising your privacy and online security.
