I go skating once or twice a week and I usually feel like I’ve done a good workout at the end. But tonight I attended an actual training fitness skating session and wow…. No words lol big eye opener for how fitter I need to get! This year is all about health improvements 🙏

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!

I wrote a post on creating "scalable research tooling for agent systems" and I'm also releasing the companion MCP server which lets you do autonomous Frida instrumentation on Android. Details in thread 👇📲🪝

Introducing my Bug Bounty Masterclass. 100% free.
I've made $2,000,000+ finding security bugs. I spent the last year turning my methodology into a complete blueprint.
4 hours of video - foundations, reconnaissance, web proxies, hands-on challenges, and certification.
Finish it in a weekend and start hacking real-world applications 🐞

So what do you bug bounty guys say? I found a complex chain (auth bypass, code injection -> code exec in gitlab ci -> exfil secrets (prod) via http) - got just 50% of P1 full payout because I am told that some internal system reported immidiately ... fair? not fair?
