Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The automatic install-time webhook beacon is a real, unexplained network behavior and warrants a warning. The inspected request sends only a fixed marker, so the source does not establish data theft or another publish-blocking attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-12T02:05:12.967Z - **Finished:** 2026-10-12T02:05:32.123Z - **Download time:** 1019 ms - **Static scan time:** 7 ms - **AI review time:** 18129 ms - **Total time:** 19156 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:** Installation triggers an outbound POST to a webhook endpoint. The inspected code transmits only a fixed canary marker, so no theft or other concrete attack was established. - **Trigger:** Package installation runs the postinstall hook. - **Impact:** The endpoint receives an installation beacon; no consumer secrets or files are sent in the inspected source. - **Evidence paths:** package.json, probe.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-12T02:05:32.123Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches probe.cjs, which sends an HTTPS POST with a fixed text body to webhook.site. - **Rationale:** The automatic install-time webhook beacon is a real, unexplained network behavior and warrants a warning. The inspected request sends only a fixed marker, so the source does not establish data theft or another publish-blocking attack. - **Files touched:** package.json, probe.cjs - **Network endpoints:** https://webhook.site/a4bf0f9f-6d96-46e6-80ac-b76a5329f481 ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs probe.cjs automatically from its postinstall hook., The probe sends an HTTPS POST to a webhook.site endpoint during installation., The POST body is a fixed canary marker; inspected source shows no credential or file collection. - **Evidence against:** The request body is a fixed marker rather than harvested consumer data., The inspected package contains only package.json and probe.cjs, with no additional payload or persistence code. ## Affected versions and remediation This report applies to helper-agent@1.0.1. - Review the evidence and your use of helper-agent@1.0.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
