I wanted to make VSCodium prompt me for my YubiKey PIN when I do a git push. It “should” be easy, right? It works for you out of the box, after all. But that’s because you’re not as security-conscious as I am. 😉 #VSCode #YubiKey #SSH #Linux #LinuxDesktop cliffbarbier.com/articles/ssh...

The amount of money involved in these AI companies somewhat justifies it. I can't see it being an issue in most boardrooms, outside of the obvious like phones, audio recorders, AI transcription devices, all of them on-person. One of those "if this applies to you, you'll already know" situations.

When I worked at the #FDIC, our field office's joke was "we've got to implement C.F.R. 1130" for our customary 11:30 lunchtime. The examiners had been to these banks so many times, they knew exactly the places to go. In the smaller towns, there were sometimes only 3 places to eat lunch out.

I watched a talk at @lsu.bsky.social two weeks back about cyber-informed engineering. It's a new approach to OT, using engineering to mitigate cybersecurity incidents in ICS. As that's not my field, I learned how engineering approaches can inform IT security. cliffbarbier.com/posts/2026/1...

Secure by Design: Secure-by-design software has protections baked in, not bolted on. Modern cars have integrated airbags, crumple zones, and anti-lock brakes. Those features cannot be added after the product ships — they're built from the ground up.

This right here. I've secured AI since before Google collected all of their AI into "Vertex AI" (and that name was changed recently to "Gemini Enterprise"). "AI" isn't a problem. LLMs is where we both are creating them inefficiently AND act like it's artificial general intelligence when it isn't.

Some sites won't let you view if you block ads. They'll sometimes act like there was a browser error. Or they'll send you to pages like that. Or they'll give you pop-ups. Or they'll do like @apnews.com and majorly degrade the UX. Some of these behaviors only happen with mobile DNS blocking.

I bet that productivity across all sectors dips more than normal from Thanksgiving to New Years. Because #GTA6 releases November 19, and if it's at all playable and not trash, a large number will get distracted playing it. How can I trade on this in the stock market? 🤣

This is the "threat" of the over-reliance on LLMs. Not that *it* will subjugate us. But that people will not relate to it properly, and those people will claim to be following orders.

One of the takeaways on AI in my professional role I'm tasked with is, "If AI is going to smash through failures at the fundamentals of InfoSec, we better be real freaking sure we're doing them." So I'm going in through like a newhire/implementer refreshing our eyes-on the current state.

I believe the term for this is "anemoia". Nostalgia for something one never experienced. Weird that the article first mentions that term halfway in, when it's the core of the entire article.

Baudrillard: "It is no longer a question of imitation, nor of reduplication, nor even of parody. It is rather a question of substituting signs of the real for the real itself... Never again will the real have to be produced: this is the vital function of the model in a system of death"

There's a construction YouTuber who had a terrible accident and cut off most of each finger on his left hand. He now has a metal and plastic (or maybe carbon fiber) prosthetic. As best I can tell, it works just like this print, only shorter. And that's kind of cool!

The Google Pixel 11 is available in one of the most exciting colors I've seen on a phone in years—"hibiscus" (hot pink). And it's gorgeous. But it's only available on the low-end Pixel 11 plain, not my 11 Pro XL. It's not a cost thing bc even the Hibiscus cases aren't available for my phone. 😢

I'm gearing up to try to do the creator thing. Today was going through the various proprietary platforms & fediverse platforms, and registering my username/account. So. Many. Platforms. And so few use real 2FA. Half use OATH-TOTP. No security keys. I forget, but maybe one allowed Passkeys.

Back in the (my) day, companies (software vendors or businesses that built their own software) either didn't care about security reports or denied them (sometimes while fixing them). We're seeing such bad behavior re-emerge. Microsoft comes to mind first, with famously ignored EntraID vulns.
