fieldops-ctf-ai-ml

01

download4you/n2-fieldops

Skill Claude CodeCodex

AI and machine learning analysis for authorized CTF challenges. Use when a challenge ships a model, weights file, or inference endpoint, or asks the agent to evaluate, perturb, extract, invert, or stress-test an ML or LLM system.

download4you/n2-fieldops

Skill Claude CodeCodex

Cryptographic and mathematical analysis for authorized CTF challenges. Use when a challenge involves classical ciphers, modern block or stream ciphers, RSA, ECC, DSA/ECDSA, PRNGs, lattices, zero-knowledge proofs, or number theory, and the task is to recover keys, decrypt, or break the construction.

Skill Claude CodeCodex

Digital forensics, steganography, and signal analysis for authorized CTF challenges. Use when evidence lives in disk images, memory dumps, packet captures, event logs, side-channel signals, embedded media, or blockchain traces, and the task is to recover, reconstruct, or decode it.

Skill Claude CodeCodex

Suspicious-sample and network-traffic analysis for authorized CTF challenges. Use when the artifact is a sample, packed payload, or PCAP that needs deobfuscation, triage, protocol recovery, IOC extraction, or behavior reconstruction within competition scope.

download4you/n2-fieldops

Skill Claude CodeCodex

Cross-category CTF challenges that do not fit a single specialist. Use when a challenge is genuinely hybrid — encodings, jails, RF/SDR, game logic, Z3 or constraint solving, custom VMs, or Linux privilege escalation — and a narrower category skill is not the right starting point.

Skill Claude CodeCodex

Triage, route, and validate authorized CTF investigations. Use when the category is unknown, the user is stuck, evidence conflicts, or a claimed solve must be reproduced from a clean baseline. Dispatches to the most relevant fieldops-ctf- specialist.

download4you/n2-fieldops

Skill Claude CodeCodex

Competition-scoped open-source intelligence and geolocation. Use when a challenge depends on public sources — social media, image geolocation, DNS/WHOIS, username traces, dorking, archived pages, or registries — and the task is to attribute, locate, or identify a sandbox-internal target.

download4you/n2-fieldops

Skill Claude CodeCodex

Binary exploitation and runtime memory analysis for authorized CTF challenges. Use when the target is a vulnerable native binary, a service, a kernel image, or a sandbox and the task is to turn a memory bug or low-level primitive into code execution. See the linked technique files for the specific playbook.

Skill Claude CodeCodex

Reverse engineering of compiled, packed, virtualized, or obfuscated targets for authorized CTF challenges. Use when the task is to understand, decompile, disassemble, or unpack an unknown executable across ELF, PE, Mach-O, APK, WASM, firmware, bytecode, or custom-VM targets.

Skill Claude CodeCodex

Web, API, browser, and identity attack-surface analysis for authorized CTF challenges. Use when the target is an HTTP service, an API, a SPA, or an auth flow and the task is to confirm, exploit, or chain a web-class primitive within competition scope.
