Obsidian CEO personally wrote the official Agent Skills for his own app 🤯 These are 5 skills that fix every layer agents get wrong: → obsidian-markdown (wikilinks, callouts, embeds, frontmatter) → obsidian-bases (database views with filters, formulas, aggregations) → json-canvas (visual canvases linked to your notes) → obsidian-cli (search, create, manage tasks from the terminal) → defuddle (clean markdown from any web page) MIT licensed. Works with Claude Code, Codex CLI, OpenCode.

claude-red is a curated library of offensive security skills designed for the Claude skills system. Each skill is a structured SKILL.mdfile that primes Claude with expert-level methodology for a specific attack surface from SQLi to shellcode, EDR evasion to exploit development.

Hacking AI Agents: Lessons Learned Breaking AI Systems ...with Johann Rehberger x.com/i/broadcasts/1jxXgejQZ…

I want to share a quick thought for people in cyber security. This will be my longest tweet ever. I’ve spoken to many lately who are having an existential crisis from the constant posts about “the end of cybersecurity jobs.” Yes, things are changing quickly. This is a significant moment for the tech industry. Change can be uncomfortable. But we’ve seen cycles like this before. • When GitHub and open source took off, people said software engineers would disappear because code was free. • When AWS and cloud computing emerged, people said infrastructure jobs would vanish. • When fuzzing and SAST tools improved, people said vulnerability research would disappear. • Virtualization would eliminate infrastructure jobs. • Mobile computing was going to end desktop dev. • Exploit mitigations would end exploitability. It didn't. Each time automation improved, the amount of software grew faster than the automation. It does feel "different" this time as it's explosive. Some roles will shrink: • repetitive pentesting • basic vulnerability scanning • tier-1 SOC monitoring But other areas are expanding rapidly: • AI system security • supply chain security • identity architecture • autonomous agent security • critical infrastructure protection Historically, every time we eliminate one class of bugs, new classes emerge. Right now people are vibe-coding entire systems, giving AI access to their machines, crossing trust boundaries, and deploying autonomous agents with excessive permissions. The legal and regulatory world is nowhere close to ready. There will absolutely be new failure modes. Humans are amazing and always adapt, finding new ways to do things. The worst thing you can do right now is fall into a doom loop. ...and I’ll be honest, I too have felt the "psychological paralysis" a few times thinking, “Is this time different?” It's especially impactful when it comes from someone I respect in the community. There are certainly unknowns, in an industry where we've become accustomed to predictability. But... the majority of those reactions are usually driven by social media, not reality. Platforms like X reward engagement, and sensational doom posts spread faster than measured thinking. If you see something like: “Holy #$%^! Opus 66.6 just found every bug in Chrome and replaced 50 startups!” …mute it and move on. Instead: Stay curious. Learn the new technology. Adapt your skillsets. Build things. We’ll get through this transition the same way we always have. If I'm wrong then Sam Altman better be right about UBI! :) I'm sure that if this tweet gets any engagement that I'll get some heat for it, but a good friend of mine reminds me often to focus on what you have control over. I'll revisit this tweet at DEF CON 40!

I’ve been through a lot… but I appreciate Arsenio and SPIN Magazine @spinmag for writing this article to help me tell my story so it can help others who have struggled too. You don’t have to become a statistic after abuse. You can still lead with good intentions and push forward to achieve your dreams. Find ways through those locked doors. If you’ve ever suffered from an abusive household or situation, you aren’t alone and I’m here for you. I love you. You are strong. You can do anything you set your mind to. 💜🦾 spin.com/2026/02/alyse-zaval… #hacker #rockstar #abusesurvivor #tour #barelyhuman

Awww yayyyyy!! I’m honored @PhillipWylie 🥰🥹

Over the last few years I have done quite a bit of AI tooling and I thought it was a good time to share some of my learnings. I'm really interested in feedback from other people who are working on similar things! Blog: knifecoat.com/Posts/Scalable… GitHub: github.com/FuzzySecurity/kah…
