주요 카테고리에 깔끔하게 속하지 않는 CTF 문제를 위한 다양한 기법을 제공합니다.

ctf-misc란 무엇인가요?

이 기술은 CTF(Capture The Flag) 대회에서 주요 카테고리(웹, 포너블, 리버싱, 포렌식, 악성코드 분석, OSINT, 암호학 등)에 명확히 속하지 않는 애매하거나 여러 카테고리가 혼합된 문제를 해결하기 위한 전문 도구입니다. 인코딩 퍼즐, 파이썬 셸(pyjail), 배시 셸(bash jail), 무선 주파수/소프트웨어 정의 무전(RF/SDR), DNS 변칙, 유니코드 트릭, 난해한 프로그래밍 언어, QR 코드/오디오 퍼즐, 제약 조건 해결, 게임 이론, 샌드박스 탈출, 하이브리드 논리 퍼즐 등 다양한 비정형 문제에 유용합니다. 주로 AI 코딩 어시스턴트(예: Claude Code, Cursor, Codex 등) 또는 터미널 기반 에이전트에서 사용되며, 문제가 명확히 특정 카테고리(예: 웹, 포너블 등)로 분류될 경우 더 전문화된 기술을 먼저 사용하는 것이 좋습니다. 이 기술은 특정 카테고리에 속하지 않거나 여러 영역에 걸친 '애매한' 문제를 위한 최후의 보루 역할을 합니다.

ctf-misc은(는) 무엇을 하나요?

주요 카테고리에 깔끔하게 속하지 않는 CTF 문제를 위한 다양한 기법을 제공합니다. 인코딩 퍼즐, pyjail, bash jail, RF/SDR, DNS 변칙, 유니코드 트릭, 난해한 언어, QR코드 또는 오디오 퍼즐, 제약 조건 해결, 게임 이론, 특이한 샌드박스 탈출, 하이브리드 논리 퍼즐에 사용하세요. 문제가 주로 웹, 포너블, 리버싱, 포렌식, 악성코드, OSINT 또는 암호학인 경우 먼저 더 구체적인 기술을 선호하세요. 이 기술을 진정한 교차 카테고리 또는 예외적인 문제를 위한 대체 기술로 취급하고, 기본 시작점으로 사용하지 마세요.

Individual skills in this repo

This repo contains 10 individual skills — each has its own dedicated page.

ljagiello/ctf-ai-ml

Provides AI and machine learning techniques for CTF challenges. Use when attacking ML models, crafting adversarial examples, performing model extraction, prompt injection, membership inference, training data poisoning, fine-tuning manipulation, neural network analysis, LoRA adapter exploitation, LLM jailbreaking, or solving AI-related puzzles.

ljagiello/ctf-crypto

Provides cryptography attack techniques for CTF challenges. Use when attacking encryption, hashing, signatures, ZKP, PRNG, or mathematical crypto problems involving RSA, AES, ECC, lattices, LWE, CVP, number theory, Coppersmith, Pollard, Wiener, padding oracle, GCM, key derivation, or stream/block cipher weaknesses.

ljagiello/ctf-forensics

Provides digital forensics and signal analysis techniques for CTF challenges. Use when analyzing disk images, memory dumps, event logs, network captures, cryptocurrency transactions, steganography, PDF analysis, Windows registry, Volatility, PCAP, Docker images, coredumps, side-channel power traces, DTMF audio spectrograms, packet timing analysis, CD audio disc images, or recovering deleted files and credentials.

ljagiello/ctf-malware

Provides malware analysis and network traffic techniques for CTF challenges. Use when analyzing obfuscated scripts, malicious packages, custom crypto protocols, C2 traffic, PE/.NET binaries, RC4/AES encrypted communications, YARA rules, shellcode analysis, memory forensics for malware (Volatility malfind, process injection detection), anti-analysis techniques (VM/sandbox detection, timing evasion, API hashing, process injection, environment checks), or extracting malware configurations and indicators of compromise.

ljagiello/ctf-osint

Provides open source intelligence techniques for CTF challenges. Use when gathering information from public sources, social media, geolocation, DNS records, username enumeration, reverse image search, Google dorking, Wayback Machine, Tor relays, FEC filings, or identifying unknown data like hashes and coordinates.

ljagiello/ctf-pwn

Provides binary exploitation techniques for CTF challenges. Use when you already have a vulnerable native target or service and need to turn memory corruption or low-level primitives into code execution or privilege escalation, such as buffer overflows, format strings, heap bugs, ROP, ret2libc, shellcode, kernel exploitation, seccomp bypass, sandbox escape, or Windows/Linux exploit chains. Do not use it when the main blocker is understanding what the binary does; use reverse engineering first. Do not use it for pure web bugs, disk or packet forensics, or standalone crypto/math challenges.

ljagiello/ctf-reverse

Provides reverse engineering techniques for CTF challenges. Use when the main job is to understand how a compiled, obfuscated, packed, or virtualized target works before exploiting or solving it, including binaries, APKs, WASM, firmware, custom VMs, bytecode, game clients, malware-like loaders, and anti-debug or anti-analysis logic. Do not use it when the vulnerability is already understood and the remaining task is exploitation; use pwn instead. Do not use it for pure web workflows, log or disk forensics, or standalone crypto problems unless reversing the implementation is the real blocker.

ljagiello/ctf-web

Provides web exploitation techniques for CTF challenges. Use when the target is primarily an HTTP application, API, browser client, template engine, identity flow, or smart-contract frontend/backend surface, including XSS, SQLi, SSTI, SSRF, XXE, JWT, auth bypass, file upload, request smuggling, OAuth/OIDC, SAML, prototype pollution, and similar web bugs. Do not use it for native binary memory corruption, reverse engineering of standalone executables, disk or memory forensics, or pure cryptanalysis unless the web flaw is still the main path to the flag.

ljagiello/ctf-writeup

Generates a single standardized submission-style CTF writeup for competition handoff and organizer review. Use after solving a CTF challenge to document the solution steps, tools used, and lessons learned in a structured format.

ljagiello/solve-challenge

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.
