The security of encrypted Web traffic depends upon a set of Certificate Authorities (CAs). Browsers and operating systems are configured with a list of CAs that they trust. The system is brittle, in the sense that if any of the multitude of CAs that your browser trusts is incompetent or malign, the security of all your traffic is imperiled. I've written several times on the topic of misbehaving CAs; there is a list of links at the end of the post.
In Web trust dies in darkness: Hidden Certificate Authorities undermine public crypto infrastructure, Thomas Claiburn reports on an important paper, Rusted Anchors: A National Client-Side View of Hidden Root CAs in the Web PKI Ecosystem by Yiming Zhang et al. This paper looks at what happens when, by fair means or foul, unofficial entries are added to or replace the CAs in the official list that your browser trusts. Below the fold I discuss their findings.

The $65B Prize
Senator Everett Dirksen is famously alleged to have remarked "a billion here, a billion there, pretty soon you're talking real money". There are a set of Bitcoin wallets containing about a million Bitcoins that are believed to have been mined by Satoshi Nakamoto at the very start of the blockchain in 2008. They haven't moved since and, if you believe the bogus Bitcoin "price", are currently "worth" $65B. Even if you're skeptical of the "price", that is "real money". Below the fold, I explain how to grab these million Bitcoin and more for yourself.

I Confess To Right-Clicker-Mentality
Gault and Pearson explain the meme:
what is the “right-clicker mentality”? Quite literally, it is referring to one’s ability to right-click on any image they see online to bring up a menu and select the “save” option in order to save a copy of the image to their device. In this term we have a microcosm of the entire philosophical debate surrounding NFTs.I join in below the fold.
