Capture the Flag for Developers
summary
Argues that hands-on CTF events beat lectures for retention and gives concrete how‑to: avoid testing production code, deploy use cloud VMs per team (AWS VPC scripted), start from known vulnerable apps or deliberately back out fixes from open‑source, and automate XSS detection with a Selenium bot for XSS to capture flags. Recommends distributing identical Kali images, linear challenge progression (no more than 3–4 core vuln types per class), simple flag plumbing (cookie or per‑user message), and nuke‑and‑rebuild VM recovery.
