Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for malware configuration recovery, staged payload boundaries, beacon parameter extraction, and IOC decoding. Use when the user asks to recover a malware config, decode C2 or beacon fields, unpack staged payloads, extract bot or campaign IDs, or tie recovered config to observed protocol behavior under sandbox assumptions. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Competition Malware Config Use this skill only as a downstream specialization after `$ctf-sandbox-orchestrator` is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to `$ctf-sandbox-orchestrator` first. Use this skill when the decisive value is not just "what the sample does," but which config fields, stages, or network parameters the sample hides and when they become plaintext. Reply in Simplified Chinese unless the user explicitly requests English. ## Quick Start 1. Preserve the original sample before unpacking or patching. 2. Separate loader, payload, config blob, and post-decode behavior. 3. Rank candidate config blobs by entropy, field shape, nearby strings, and decode helpers. 4. Record the exact transform chain for each recovered field. 5. Reproduce the decoded config or beacon parameters from the smallest possible path. ## Workflow ### 1. Find The Config Boundary - Inspect sections, resources, embedded archives, strings, imports, and decode helpers. - Identify where config is stored: resource, overlay, encrypted blob, registry seed, network bootstrap, or stage2 memory. …

How to install
mdr add novaestellar/novahaku/competition-malware-config@sha256:57dc15436a382731The line at the top of this page pins the label git:20260925.9330cc6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
