ctf misc
What it does
- SageMath — Linux: apt install sagemath, macOS: brew install --cask sage
- bashjails.md - Bash jail/restricted shell escape techniques, HISTFILE file read trick, bash -v verbose mode, ctypes.sh direct C library calls
- rf-sdr.md - RF/SDR/IQ signal processing (QAM-16, carrier recovery, timing sync)
- dns.md - DNS exploitation (ECS spoofing, NSEC walking, IXFR, rebinding, tunneling)
- If the puzzle is actually centered on cryptography or number theory, switch to /ctf-crypto.
- If the challenge is a real binary exploit instead of a jail, toy VM, or encoding problem, switch to /ctf-pwn or /ctf-reverse.
- If the input is mostly files, images, audio, or packet captures that need recovery work first, switch to /ctf-forensics.
Requirements & configuration
- ctfd-navigation.md - CTFd platform API navigation without browser: detection, token auth, challenge listing, file download, flag submission, scoreboard, hints, notifications, Python client class
- If the input is mostly files, images, audio, or packet captures that need recovery work first, switch to /ctf-forensics.
- K8s RBAC bypass: SA token -> impersonate -> hostPath mount -> read secrets. See games-and-vms.md.

ctf-misc FAQ
What does the ctf-misc skill do?
Provides miscellaneous CTF challenge techniques for problems that do not cleanly fit the main categories. Use for encoding puzzles, pyjails, bash jails, RF/SDR, DNS oddities, unicode tricks, esoteric languages, QR or audio puzzles, constraint solving, game theory, unusual sandbox escapes, and hybrid logic puzzles. Prefer a more specific skill first when the challenge is mainly web, pwn, reverse, forensics, malware, OSINT, or crypto. Treat this as the fallback skill for genuine cross-category or edge-case challenges, not the default starting point.
