This week we add Bruce Schneier's thoughts about the theoretical feasibility of contact tracing apps; we touch on our government's feelings about DNS over HTTPS; we look at yet another whacky way of exfiltrating data from an air-gapped computer; we examine a new vulnerability that has already damaged some large high-profile enterprise infrastructures; we note Adobe's latest round of critical updates, another welcome service coming from Mozilla, a dispiriting bit of over-the-top political correctness from the UK, and Google's plans to clean up the mess which is the Chrome Web Store. We then share a bit of errata, miscellany and SpinRite news, then take a look at China's proposed changes to the fundamental operation of our global Internet.
