Heading to DEFCON. Couldn't find anyone that made this so I wrote it: A flipper zero NFC canary: keep it in your pocket or bag to keep track and alarm when someone tries to scan your gear while you're walking around the con. github.com/antitree/nfc...

Few days away from leaving for #toorcamp I'm going to post on a few platforms and see which gets the most hits. I'm super nervous the answer is going to be "meet us at 40m"
k8s security training. People asking me what they should do to learn about kubernetes security well here you go.
Time to level up on K8s security. I won't oversell my Agentic AI-Aided #Kubernetes Attack & Defense class - I'll just let 4 people I respect say what they got out of it. @blackhatevents.bsky.social Las Vegas in August! tinyurl.com/bhus26-kube-... @malwarejake.bsky.social @grahamhelton.bsky.social
Tomorrow is my last day at @chainguard.bsky.social Best company ever. I may kick myself for leaving but I will definitely kick myself if I don't try out the next opportunity. I've been a fan of this company from its inception. Marketing to 4-10 year olds in my neighborhood since 2023
No judgement but if you eat out of anything labelled a "carton", you might be stress eating and I'm with you.

Idk how many times I've installed Obsidian at this point. I think at least 25. Only to uninstall no more than 5 days later.
I get very frustrated when feel like I can see a really different future of infosec and yet at the same time I'm fiddling with legacy paradigms and old thinking. There are two types of security teams right now, legacy and forward looking. Which teams have you seen that are turning the corner?
By the way, we just published another privilege-escalation CVE in ingress-nginx: github.com/kubernetes/k... 🚨 This will be the final, final release. Please migrate off ingress-nginx as soon as possible. 🚨

I did say that! Ingress-nginx *is* an infinite CVE piñata! You hit it with a stick and vulns fall out 😁
Reminder to pay attention to all those things calling themselves a sandbox. Especially looking at you "docker sandbox".
The irony that a k8s seccomp generation tool had an overly restritive seccomp policy _on itself_ causing it to crash and not generate seccomp profiles, is a fantastic example of the problem. Thanks.
Yeah, but does your city have...

I always exhaust myself putting together a talk and the cycles are always the same: * I have a good idea * Write out talk for idea * I hate my idea * Smash head against keyboard, write dozen new tools, hack previous slides to shambles, throw gibberish placeholders into a new deck * ... * Present
Rule #608: It's handy to have a local mirror of a random swath of 3000 container images for emergencies.
Seccomp container profile bypass: runc casts your seccomp's errnoRet to int16 before passing it to libseccomp. errnoRet=65536 > int16(0) > SCMP_ACT_ERRNO(0) > kernel returns 0 errors == syscall goes from blocked to allowed
I need to hear this as much as anyone: In 2026, nobody will care if you were right
Present in front of 1000 people. No biggy. Present in front of the guy that wrote App Armor.

NEW: For months, I’ve been working on the story of Peter Williams, the former U.S. defense contractor who stole several hacking tools and then sold them to a Russian broker. Here’s what we know about the case, what we still don’t know, and a peek behind the scenes at how I reported this story.

It's been a while since I've been working on some stuff and went "it would be even better if this had it's own domain..."
I have a visceral reaction to this stuff because we are repeating history. Keep them coming. The corpus grows. github.com/beelzebub-la...

My BSidesSF talk was accepted! I've always had a lot of respect for this con so I'm excited to be chosen. Details aren't out yet but I still get really psyched and nervous for talks like this. LFG
Good morning Vitamin D deficiency. Where's the Andrew Huberman protocol for when you haven't seen the sun in 3 months and your country is collapsing. Zinc?
The @bsidesbuffalo.bsky.social CFP is still open through March. You should submit that talk idea that you have. Reasons why: * It'll be an even better idea once you write it down * You're going to kick yourself in a month for not submitting * You're smarter than you think www.bsidesbuffalo.org/cfp/
