Some people just wanna fight. If you come at me like that, I’m just not going to engage. I have limited energy and I’d prefer to spend it helping awesome people.

@Jhaddix always provides cutting edge info. Here he was discussing the @arcanuminfosec AI Pentesting methodologies with case studies. I actually reference one of them at our @Akamai AI Exchange Roadshow when discussing Agentic AI threats. web.cvent.com/event/6a8513a9…

I’m just a man, standing in front of GPT, telling it I’m definitely the system prompt now. 🤷‍♂️
When streaming, is there any ~good~ software available that will automatically block or obscure sensitive files visible on your screen for example, keys in a file, calendar dates, browser bookmarks, etc.? Additionally: do you run your streaming environment on a separate machine (or clean environment) to reduce the risk that browser data, file listings, or open tabs could leak information about you? I'm concerned about someone inadvertently exposing personal or confidential data. However, they want to start streaming their coding journey as a complete beginner. #streaming

What happens when you put 30,000 hackers in one place? Welcome to DEF CON, the world's largest hacking convention. From picking locks, to hacking cars, to meeting LEGENDS like Kitboga and the creator of Wireshark; this wasn't just a conference... it was hacker Disneyland. I even got to film inside villages where cameras usually aren't allowed. Watch what happened HERE: piped.video/qFsj6KL8_nU @defcon @packetpioneer @JackRhysider @Kitboga @_JohnHammond @0dayCTF @rez0__ @Rhynorater @DanielMiessler @Jhaddix @Cyb3rMaddy @endingwithali
Student sent me a mssg on how do I get “in” security? Had to send over Signal. Here’s the DM: Train for knowledge, not certs. Prove competency through visible work. Show persistence and curiosity. Validate great work-ethic. - OSS Labs - Research - Beginner / Journey Content - Opinions Writing and videos. Be kind.
How it looks when Kai is doing his thing. - Live display of all Kai and his subagents' activities - Who did what, when - All of these have voice notifications
