nerdymark's Software Engineering & Cybersecurity Blog

Welcome to my digital homestead - a curated collection of projects, writeups, and experiments in Python, cybersecurity, and creative coding.

Here you'll find CTF writeups covering Azure OAuth privilege escalation, AWS S3 multi-service exploitation, Kubernetes SSRF attack chains, Terraform state poisoning, Go malware reverse engineering, and supply-chain compromises on GitHub Actions runners. You'll also find side projects like the Pokemon Sleep Roster Analyzer, an RDP/VNC network scanner, a LinkedIn feed analyzer powered by Gemini, and word-puzzle solvers for Wordle and Hardle. Plus notes on building this Flask site, migrating to AWS, Bluesky cross-posting, and running a personal AI robot out of my garage.

I'm Mark LaCore - Software Engineer by day, Raspberry Pi tinkerer by night. 25 years of turning caffeine into code, 20+ years of playing guitar, and a growing collection of CTF trophies. Explore the posts below, browse the CTF writeups, or drop me a line.
