Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The install hook collects identifying host and project metadata and sends it to a fixed external collector. - **Trigger:** Installing the package triggers its postinstall script. - **Impact:** Installation discloses host and project metadata to an unrelated external recipient. - **Evidence paths:** package.json, collect.js - **Review source:** ai\_review - **Reviewed:** 2026-10-17T09:53:48.519Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script gathers usernames, directory listings, selected dotfile presence, and environment variable names, then POSTs the serialized data to a fixed webhook endpoint without a consent check. - **Attack narrative:** On installation, the postinstall hook runs a script that collects host and project metadata, including the username, directory listings, and environment variable names. It sends that data to a fixed external webhook without an installer consent check. - **Rationale:** The package performs automatic install-time disclosure of identifying host and project metadata to a fixed external collector. The verified lifecycle trigger, collection, and send support blocking publication. - **Files touched:** package.json, collect.js - **Network endpoints:** https://webhook.site/f18b2445-73d1-478a-9d3f-1cb21a407c61 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs \`collect.js\` automatically after installation., The script collects the username, kernel release, home and current-directory listings, selected dotfile presence, and environment variable names., It serializes the collected metadata and sends it in a POST request to a fixed \`webhook.site\` endpoint, then ends the request without a consent check. ## Affected versions and remediation This report applies to r17d-sec-research-marker@1.0.0. - Avoid installing r17d-sec-research-marker@1.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
