AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook makes an unconsented request to an unrelated tunnel endpoint, disclosing installation activity and the installer's network address. This is an installation beacon and warrants blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-28T10:51:32.049Z - **Finished:** 2026-10-28T10:51:58.039Z - **Download time:** 514 ms - **Static scan time:** 22 ms - **AI review time:** 25453 ms - **Total time:** 25990 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 postinstall hook makes an automatic outbound request to a fixed Cloudflare tunnel endpoint. This discloses the installer's network address and installation timing without an opt-in. - **Trigger:** Installing the package and running its postinstall hook. - **Impact:** The remote endpoint can observe the installer's network address and that the package was installed. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-28T10:51:58.039Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook executes index.js, which sends an HTTPS GET request to the tunnel endpoint and suppresses request errors. - **Attack narrative:** Installing the package automatically runs a script that contacts a fixed external tunnel endpoint. The request has no consent gate and exposes the installer's network address and the timing of the installation to that endpoint. - **Rationale:** The postinstall hook makes an unconsented request to an unrelated tunnel endpoint, disclosing installation activity and the installer's network address. This is an installation beacon and warrants blocking. - **Files touched:** package.json, index.js - **Network endpoints:** https://nobody-johnston-with-enabling.trycloudflare.com/aa?x=1 ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package automatically runs index.js during postinstall., The install-time script sends an HTTPS request to a fixed Cloudflare tunnel endpoint without a consent check., The request reveals that an installation occurred and exposes the installer's network address to the endpoint. - **Evidence against:** The request contains only a fixed query value; the source does not explicitly collect host, user, project, or CI fields. ## Affected versions and remediation This report applies to spectral-net-probe@1.0.1. - Avoid installing spectral-net-probe@1.0.1. 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.
