Hey, I'm Karlo.
Most people online know me as AccidentalRebel. I work in security, build tools, and write about what I find.
By day, I lead L2 security operations for a 24/7 SOC and run a content engineering team at TryHackMe, where we build hands-on security training used by 3M+ people worldwide. Before cybersecurity, I spent 10+ years as a software engineer: games, web apps, dev tools, low-level systems. I think like an attacker, but I build for defenders.
What I Do
I sit at the intersection of security and AI. That means:
- Detection engineering and threat hunting. Building and tuning detections in Microsoft Sentinel, investigating what the automated systems miss.
- Security tool development. I don't just use tools, I build them. VGL4NT (ML-based malware classification), shcode2exe (shellcode analysis), Claudecker (AI agent containment), and others.
- AI x Security. Exploring how AI changes both sides of the security equation, from AI-powered detection to AI as an attack surface.
What I Write About
Every week I publish a Cybersecurity x AI News Roundup. Curated analysis of where AI and security collide, with editorial commentary drawn from hands-on experience. No hype, no vendor pitches, just what matters and why.
I also write deep dives on malware analysis, reverse engineering, and the tools I build along the way. If you've taken a room at TryHackMe, we may have already crossed paths.
Background
- Computer Engineer by training. The hardware-to-software full stack.
- 10+ years in software engineering before pivoting to security
- SANS GIAC GSLC certified
- CISSP (in progress, May 2026)
Let's Talk
I'm always up for conversations about security engineering, AI in security, or interesting problems that need building.
