Younger Americans have soured on the second Donald Trump presidency, but they are not protesting it. Despite an unpopular Iran war and an even more unpopular Trump administration, college campus protests nationwide have gone silent. And at many schools, student activism is virtually nonexistent.

Introducing Insights: self-serve reporting for security teams by Andrea Meza on 28/05/2026
Security teams running Bug Bounty programs often require similar insights and reporting to prove the value and ROSI for security initiatives, and often ask questions such as: What changed? Where are we spending? Are we improving? What needs attention right now? Until now, answering those questions often meant exporting data, stitching together spreadsheets, or pulling screenshots from [...]

Identifying People Using Wi-Fi Routers on 26/05/2026
Not identifying people based on their use of Wi-Fi routers, but identifying people using Wi-Fi signals. This is accomplished through what is known as WiFi sensing, or the use of WiFi signals to infer information about a physical environment. When radio signals like WiFi travel through a space, they interact with the objects and people around them. Those signals can be reflected, scattered, or abso [...]

What Your Board Gets Wrong About AI Security by Tim Erlin on 18/05/2026
Editor's note: This article was originally published by Craig Riddell on LinkedIn. It has been republished here with the author's permission. Boards are giving AI security more airtime than ever. What they're not giving is the right framing. A year or two ago, AI was mostly a question of experimentation risk.
