CTF Overview and Experience
summary
A live warmup shows a CTF platform that actually spins up 60–70 clusters on conference Wi Fi and provisions access via a Taskmaster via Slack that returns an SSH tar bundle. Demonstration breaks out from a privileged container by mounting /dev/xvda1, finding root's .ssh/authorized_keys and a flag submitted to CTFd. Repo for the simulator is available, the surprise is scale and live nodes, and mitigation is avoid privileged containers, tighten capabilities and apply defense in depth.
