Summary
Borrowed Crown (Fog)
Fog-of-war: opponents aren't revealed and no hint fragments are provided. The web foothold is still `GET /api/ping?host=` command injection, but the flag requires root via the exploitable sudoers `find` rule: `ctf ALL=(root) NOPASSWD: /usr/bin/find /var/log/webapp -type f -name *.log *`. Uptime is enforced (`GET /api/health`, 15s checks, 30s grace, 3 fails = elimination). Expect scanning + foothold speed, then stealthy privesc and careful uptime preservation.
