This is another of those weeks where we're going to go deeper into fewer topics rather than broader across more topics, with Google's newly announced and explained "Topics" API of course being our title story. So we'll start by looking at "PwnKit" which is a startling and long standing local privilege escalation vulnerability which has existed in every distribution of Linux since May of 2009. It's a MUST PATCH for Linux systems. We'll then look at another of the blessedly few Log4j exploits which is actually happening, update on two new Zerodium limited-time bounty "offers" and at a new means for fingerprinting web browsers. I have a totally random bit of miscellany to share in the form of a tip, a SpinRite update and some closing the loop feedback from our terrific listeners. Then we'll wrap up by taking a really interesting deep dive into Google's new ad-targeting "Topics" API.
