r17d-sec-research-marker@1.0.0
SECURITY RESEARCH POC MARKER - install-script execution test in managed dev sandboxes. Labeled; unpublished immediately after verification. Collects metadata only (usernames, directory listings, file EXISTENCE). No secret values, no persistence.
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe 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.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installing the package triggers its postinstall script.
Impact
Installation discloses host and project metadata to an unrelated external recipient.
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.
AI 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.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
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.
