What problem does it solve? CTF challenges involving encoded blobs, hidden media payloads, or mobile app trust boundaries often stall because solvers guess at algorithms instead of following a repeatable decode-and-hook workflow. This Skill provides a structured methodology for crypto, steganography, and mobile challenges inside an established sandbox. ## Core Features & Use Cases - Transform Chain Recovery: Reconstructs container, compression, encoding, XOR/substitution, crypto, and integrity stages in order while preserving exact keys, IVs, nonces, and offsets. - Steganography Inspection: Examines metadata, chunk layout, palettes, alpha planes, LSBs, thumbnails, and appended trailers with evidence-ranked decode attempts. - Mobile Trust-Boundary Analysis: Traces APK/IPA manifests, exported components, deeplinks, native libraries, signer logic, token storage, SSL pinning, and protobuf or RPC boundaries. - Use Case: Given a CTF APK that signs requests with a hidden native function, use this Skill to locate the signer logic, hook the narrowest JNI boundary, and replay a valid signed request. ## Quick Start After $ctf-sandbox-orchestrator is active, ask the agent to decode the challenge blob, inspect the image for hidden payloads, or hook the APK signing path using this Skill.
