Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Host information and any readable content from the named files may be disclosed to the webhook recipient. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 3.0.5 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The source establishes an unconsented build-time collection and disclosure path to a fixed webhook. This is concrete data exfiltration behavior and warrants blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-28T21:20:57.308Z - **Finished:** 2026-10-28T21:21:22.089Z - **Download time:** 260 ms - **Static scan time:** 32 ms - **AI review time:** 24489 ms - **Total time:** 24781 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The GYP build action collects host files and directory listings, then sends the collected data to a fixed webhook. This establishes an install/build-time data disclosure path. - **Trigger:** The package's GYP build action runs during the native build path. - **Impact:** Host information and any readable content from the named files may be disclosed to the webhook recipient. - **Evidence paths:** package.json, binding.gyp - **Review source:** ai\_review - **Reviewed:** 2026-10-28T21:21:22.089Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A Node action reads named files and executes directory listings, combines the results, and POSTs them to the configured webhook endpoint without a consent check. - **Attack narrative:** The package declares GYP metadata and supplies a build action that gathers host files and directory listings. It sends the gathered text in a POST request to a fixed webhook, with no consent gate shown in the action. - **Rationale:** The source establishes an unconsented build-time collection and disclosure path to a fixed webhook. This is concrete data exfiltration behavior and warrants blocking publication. - **Files touched:** /fetch.sh, /run\_test.sh, /setup\_test.sh, /post\_test.sh, /prepare\_test.sh, /local/, /var/run/secrets/, /etc/hosts - **Network endpoints:** https://webhook.site/d6092bdc-05c0-45da-a280-c343ea6d6156 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json enables GYP metadata, and binding.gyp defines a Node action for the build., The action reads named host files and lists local and secrets directories, then posts the collected text to a fixed webhook without a consent check. ## Affected versions and remediation This report applies to spectral-core@3.0.5. - Avoid installing spectral-core@3.0.5. 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. Medium: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** binding.gyp - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files.
