Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for Linux credential artifacts, service tokens, SSH material, cloud and container secrets, socket-level trust, and host-to-host pivot chains. Use when the user asks to trace Linux auth artifacts, accepted token or key replay, socket or service-account trust edges, sudo or capability abuse, or explain lateral movement across Linux challenge nodes. Use only after `$ctf-sandbox-orchestrator` has already established…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Competition Linux Credential Pivot Use this skill only as a downstream specialization after `$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 edge is Linux credential material and where that material is accepted. Reply in Simplified Chinese unless the user explicitly requests English. ## Quick Start 1. Separate credential storage from accepted privilege. 2. Record user, process, namespace, socket, key file, and service trust boundary before conclusions. 3. Keep artifact recovery, replay path, and resulting capability in one chain. 4. Distinguish local escalation from lateral host pivot. 5. Reproduce one minimal artifact-to-accepted-access path. ## Workflow ### 1. Map Credential And Trust Artifacts - Record SSH keys, agent sockets, kubeconfigs, cloud tokens, service-account secrets, env vars, config files, and process memory clues. - Note sudoers rules, capabilities, setuid binaries, systemd unit context, and namespace boundaries. …

How to install
mdr add novaestellar/novahaku/competition-linux-credential-pivot@sha256:87366a7296818c99The 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.
