Collect external context without touching the target aggressively.
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
# Passive Recon ## Goal 用被动来源建立目标画像，并找出值得后续主动验证的资产。 ## Tools / Inputs - DNS、证书透明度、wayback、favicon、公开搜索、历史 JS ## Constraints 1. 被动信息不是漏洞，只是线索。 2. 历史资产需要验证是否仍在线。 3. 发现历史 JS/API 后交给 JS analysis。 4. 发现子域名要按业务价值排序。 5. 避免大规模主动探测。 ## Chain Questions - 哪些历史资产可能仍指向现网后端？ - 哪些子域名像管理、测试、导出、API、SSO？ - 历史 JS 是否暴露已删除但未下线接口？ - 哪些线索值得进入 Phase 1 排序？

How to install
mdr add hellodqy/mastermind-bug-bounty/passive-recon@sha256:5fd53f65ab0a2655The line at the top of this page pins the label git:20260709.a882698, 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.
