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 postinstall network request is a real, unexplained external beacon, so a warning is appropriate. The fixed body and absence of source evidence for sensitive-data collection do not support blocking as malware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-11T22:43:21.821Z - **Finished:** 2026-10-11T22:43:38.204Z - **Download time:** 761 ms - **Static scan time:** 7 ms - **AI review time:** 15615 ms - **Total time:** 16383 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 webhook.site carrying a fixed marker. The source does not establish what receives or uses that marker, so the purpose and impact remain unresolved. - **Trigger:** Package installation runs the postinstall script. - **Impact:** It contacts an external endpoint during installation; no credential or file data is shown being sent. - **Evidence paths:** package.json, probe.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-11T22:43:38.204Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script sends a fixed text body to a webhook.site URL. - **Rationale:** The automatic postinstall network request is a real, unexplained external beacon, so a warning is appropriate. The fixed body and absence of source evidence for sensitive-data collection do not support blocking as malware. - **Files touched:** package.json, probe.cjs - **Network endpoints:** webhook.site ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs probe.cjs automatically during postinstall., probe.cjs sends a fixed canary string in a POST request to webhook.site., The package contains no other files; source does not show credential collection or a response-driven payload. - **Evidence against:** The POST body is a fixed marker, not a value read from the environment or filesystem., The request has no response processing beyond consuming the response. ## Affected versions and remediation This report applies to helper-agent@1.0.0. - Review the evidence and your use of helper-agent@1.0.0 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.
