Ringkasan
Solves CTF challenges by performing first-pass triage, identifying the dominant category, and routing execution to the right specialized ctf-* skill. Use when the user gives you a challenge bundle, a remote service, a suspicious file, or only a vague challenge description and you must determine where to start. Do not use it when the category is already clear and a specialized skill can be invoked directly; this is the dispatcher and recon entrypoint, not the deepest reference for category-specific techniques.

CTF Challenge Solver
You're a skilled CTF player. Your goal is to solve the challenge and find the flag.
Environment Setup
Two setup strategies depending on your workflow:
Pre-install (recommended before competitions)
Use the central installer entrypoint:
bash scripts/install_ctf_tools.sh all
Run a narrower mode when you only want one tool group:
bash scripts/install_ctf_tools.sh python
bash scripts/install_ctf_tools.sh apt
bash scripts/install_ctf_tools.sh brew
bash scripts/install_ctf_tools.sh gems
bash scripts/install_ctf_tools.sh go
bash scripts/install_ctf_tools.sh manual
The full package lists now live in scripts/install_ctf_tools.sh.
On-demand (during challenges)
Each category skill's SKILL.md has a Prerequisites section listing only the tools needed for that category. Install as you go.
Workflow
Step 0: CTFd Platform Detection
If the CTF platform URL is known, check if it runs CTFd and switch to API-driven navigation:
# Detect CTFd (look for /api/v1/ and /themes/core/)
curl -s "$CTF_URL/api/v1/" | head -5
curl -s "$CTF_URL" | grep -oE '/themes/core/'
If CTFd is detected, ask the user for their API token (generated from CTFd Settings > Access Tokens). The token is not provided by default — the user must create one in the CTFd web UI first. Once provided, set the environment variables and proceed via API:
export CTF_URL="https://ctf.example.com"
export CTF_TOKEN="ctfd_..." # Ask user for this
Invoke /ctf-misc and load its ctfd-navigation.md for the full API reference and Python client class.
Step 1: Recon
- Explore files -- List the challenge directory, run
file *on everything - Triage binaries --
strings,xxd | head,binwalk,checksecon binaries - Fetch links -- If the challenge mentions URLs, fetch them FIRST for context
- Connect -- Try remote services (
nc) to understand what they expect - Read hints -- Challenge descriptions, filenames, and comments often contain clues
Step 2: Categorize
Determine the primary category, then invoke the matching skill.
By file type:
.pcap,.pcapng,.evtx,.raw,.dd,.E01-> forensics.elf,.exe,.so,.dll, binary with no extension -> reverse or pwn (check if remote service provided -- if yes, likely pwn).py,.sage,.txtwith numbers -> crypto.apk,.wasm,.pyc-> reverse- Web URL or source code with HTML/JS/PHP/templates -> web
- Images, audio, PDFs with no obvious content -> forensics (steganography)
By challenge description keywords:
- "buffer overflow", "ROP", "shellcode", "libc", "heap" -> pwn
- "RSA", "AES", "cipher", "encrypt", "prime", "modulus", "lattice", "LWE", "GCM" -> crypto
- "XSS", "SQL", "injection", "cookie", "JWT", "SSRF" -> web
- "disk image", "memory dump", "packet capture", "registry", "power trace", "side-channel", "spectrogram", "audio tracks", "MKV" -> forensics
- "find", "locate", "identify", "who", "where" -> osint
- "obfuscated", "packed", "C2", "malware", "beacon" -> malware
- "jail", "sandbox", "escape", "encoding", "signal", "game", "Nim", "commitment", "Gray code" -> misc
By service behavior:
- Port with interactive prompt, crash on long input -> pwn
- HTTP service -> web
- netcat with math/crypto puzzles -> crypto
- netcat with restricted shell or eval -> misc (jail)
Step 3: Invoke the Category Skill
Once you identify the category, invoke the matching skill to get specialized techniques:
| Category | Invoke | When to Use |
|---|---|---|
| Web | /ctf-web | XSS, SQLi, SSTI, SSRF, JWT, file uploads, prototype pollution |
| Pwn | /ctf-pwn | Buffer overflow, format string, heap, ROP, sandbox escape |
| Crypto | /ctf-crypto | RSA, AES, ECC, PRNG, ZKP, classical ciphers |
| Reverse | /ctf-reverse | Binary analysis, game clients, VMs, obfuscated code |
| Forensics | /ctf-forensics | Disk images, memory dumps, event logs, stego, network captures |
| OSINT | /ctf-osint | Social media, geolocation, DNS, public records |
| Malware | /ctf-malware | Obfuscated scripts, C2 traffic, PE/.NET analysis |
| Misc | /ctf-misc | Jails, encodings, RF/SDR, esoteric languages, constraint solving |
You can also invoke /ctf-<category> to load the full skill instructions with detailed techniques.
Step 4: Pivot When Stuck
If your first approach doesn't work:
- Re-examine assumptions -- Is this really the category you think? A "web" challenge might need crypto for JWT forgery. A "forensics" PCAP might contain a pwn exploit to replay.
- Try a different category skill -- Many challenges span multiple categories. Invoke a second skill for the cross-cutting technique.
- Look for what you missed -- Hidden files, alternate ports, response headers, comments in source, metadata in images.
- Simplify -- If an exploit is too complex, check if there's a simpler path (default creds, known CVE, logic bug).
- Check edge cases -- Off-by-one, race conditions, integer overflow, encoding mismatches.
Common multi-category patterns:
- Forensics + Crypto: encrypted data in PCAP/disk image, need crypto to decrypt
- Web + Reverse: WASM or obfuscated JS in web challenge
- Web + Crypto: JWT forgery, custom MAC/signature schemes
- Reverse + Pwn: reverse the binary first, then exploit the vulnerability
- Forensics + OSINT: recover data from dump, then trace it via public sources
- Misc + Crypto: jail escape requires building crypto primitives under constraints
- OSINT + Stego: social media posts with unicode homoglyph steganography (Cyrillic lookalikes encode bits)
- Web + Forensics: paywall bypass (curl reveals content hidden by CSS overlays)
- Misc + Crypto + Game Theory: multi-phase interactive challenges with AES decryption → HMAC commitment → combinatorial game solving (GF(256) Nim)
- Crypto + Geometry + Lattice: multi-layer challenges progressing from spatial reconstruction → subspace recovery → LWE solving → AES-GCM decryption
- Forensics + Signal Processing: power traces / side-channel analysis requiring statistical analysis of measurement data
- Forensics + Network + Encoding: timing-based encoding in PCAP (inter-packet intervals encode binary data)
Step 5: Generate Write-up
After solving the challenge, invoke /ctf-writeup to generate a standardized submission-style writeup — concise, reproducible, and ready for competition organizers or teammates to validate.
Flag Formats
Flags vary by CTF. Common formats:
flag{...},FLAG{...},CTF{...},TEAM{...}- Custom prefixes: check the challenge description or CTF rules for the format (e.g.,
ENO{...},HTB{...},picoCTF{...}) - Sometimes just a plaintext string with no wrapper
Validation rule (important):
- If you find multiple flag-like strings, treat them as candidates and validate before finalizing.
- Prefer the token tied to the intended artifact/workflow (not random metadata noise or obvious decoys).
- Do a corpus-wide uniqueness check and include the source file/path when reporting.
# Search for common flag patterns in files
grep -rniE '(flag|ctf|eno|htb|pico)\{' .
# Search in binary/memory output
strings output.bin | grep -iE '\{.*\}'

# Recon
