I subscribed to get text alerts for Claude's status on outages... This was a mistake. How many 8's is the uptime on this thing?

Notepad++ versions and update mechanisms have been compromised since September. Please update to 8.9.1 wherever you have this tool. It's unclear what malicious versions of the tool might do. I Recommend activating incident response for affected hosts.

This rush to repurpose sandbox technologies to become "AI agent boxes" is great to see. Kata is an obvious option... but layering in k8s to agentic workers is going to require another layer that needs hardening.

I'm interested to see where the industry goes

Kata Containers is an open source container runtime, building lightweight virtual machines that seamlessly plug into the containers ecosystem.

How are those "I don't care about privacy, I have nothing to hide" folks doing in 2026?

See you next week at #DistrictCon. Hoping to see some familiar faces. Otherwise here's some good conversation starters that always work on me:
* "We don't know each other but... hi."
* "Would you like a beer?"
* "Any ideas how to get rid of a body?"

Just started my plans for torcamp. Looking forward to another year of insane hacker adventures in nature

As a fan of trying to secure the things that are obviously insecure, GPUs are right up there. Fun write up on how they approach this from a client OS perspective security.googleblog.com/2025/12/furt...

Shout out to the poor engineers at Anthropic that have to support the launch of a half dozen new product features announced today.

I've seen this movie before. Hackers with free time + under reviewed features...🍿

Does anyone else in snow country regularly exchange pictures of snow with friends and families to show how much in their yard?

Do they have a name? Snow-fies? Snow-tographs?

This is what we need to be discussing!

All the AI in the world and Google's cameras still think snow is someone walking

Anyone complaining that genAI image used as page filler are inaccurate or cringe, should be shown the Microsoft Office clip art gallery from the early 2000's

I'm a sucker for books that support my belief that we're all doing infosec poorly or just for the sake of infosec. This has been an interesting read so far

Uh oh. Check your GCP Cloud Run jobs.

I saw a tragically AI-generated version of this poster, so I have recreated a 100% human-made version for all your protest sign needs.

Serious question: how do people buy cars without spending weeks at it? Do you roll into dealerships and just yeet the cash at them?

Took me 3 hours to finally agree that kubernetes will do anything for Node Autoscaling based on available resources ... But it won't do THAT.

I have ChatGPT instrumenting Claude so I can failover when it hits its rate limits. And I feel like that's what you're _supposed_ to do.

Very late on getting this video out the door, but a teeny weeny showcase of the recent Docker for Desktop on Windows & MacOS container escape, CVE-2025-9074 -- proof of concept was included so a simple demo of arbitrary file write & file read on the host: youtu.be/dTqxNc1MVLE
