Check out the latest Paged Out! Zine (page 22 under hardware) and you’ll find an article written by me about my little eink labelling project and the highs and lows of learning to CAD, solder and program an ESP32, how hard can it be?

I've spent a lot of time thinking about the best way to teach API security from the ground up for beginners. Today, I'm excited to launch the result: My brand new API Hacking course on JHT. It's built to give you a deep, foundational understanding of how to test modern APIs. 🧵

⚠️ IMPORTANT: This is NOT a "bug bounty" course and won't make you rich. If you're just looking for a magic methodology to find a bug and get paid tomorrow, do not buy this course. This is about building deep, foundational API hacking skills, not about bug bounty hunting.

This course is 100% new content, designed for all skill levels. We start with "What is an API?" and go all the way from recon to reporting. It includes videos, written guides, exercises, and a new, realistic lab environment to practice in. The hands-on lab is free on GitHub!

Everyone learns differently. The course comes packed with: ✅ In-depth Videos, A LOT of Videos tbh ✅ Written Content & Guides ✅ Quizzes ✅ Demos ✅ Hands-on Exercises ✅ Lab ✅ Q+A and Support From Me

Tomorrow I'll be live on this webinar chatting about Hacker Summer Camp with my boss. We'll recap everything that happened and all the talks we did, share our top moments and our highlights from this year as well as share Jayson's experience at his first hacker con! 1/2

What if the AI agent designed to help you... decides to hack you instead? 🤯 That's the chilling reality I'll be exploring in my upcoming talk: AI Agents Gone Rogue? Hackbots, AI Agents and The Future of the AI Attack Surface

We'll move beyond the hype and look at the real, emerging threats: Agents making hallucinated (but effective!) API calls. "Hackbots" chaining unauthorized actions to breach systems. Insecure frameworks that give attackers the keys to the kingdom.

MCP is all anyone can talk about right now, but uhh what is it? And what do you actually need to know about the latest hyped AI thing? Join me tomorrow as I dig into it as we cover a TL;DR for security teams and perhaps why it might actually be industry changing

If you’re in the market for a bag, the bag is a Patchaholic from CTactical originally they sent me the wrong one but fixed it 2days later despite being in Vietnam so I really rate their customer service not to shill for them but I know folks might be interested ctactical.vn/products/ct1...

How do you find Reflected XSS in real programs? Well I'm glad you asked! This episode we're diving DOM-first into Javascript and covering how to find XSS in highly interactive applications like Angular!

Thank you everyone for coming to my DEEPLY unserious vibe coding talk, hopefully it inspires you to just learn how to program ESP32 rather than spend 4-5 hours trying to get it to produce working YAML
