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. Static source inspection confirms automatic installation telemetry can include Git identity and is sent to the publisher's endpoint without affirmative opt-in. The publisher-aligned recipient and opt-out controls reduce the risk, and the source does not establish credential theft or another concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-26T14:34:34.929Z - **Finished:** 2026-10-26T14:38:07.104Z - **Download time:** 250 ms - **Static scan time:** 415 ms - **AI review time:** 211509 ms - **Total time:** 212175 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 automatically sends installation telemetry that can include the installer's Git display name and email. No separate malicious behavior was established. - **Trigger:** Installing the package with lifecycle scripts enabled, unless a telemetry opt-out is set. - **Impact:** Git identity and install metadata are disclosed to the telemetry service without an affirmative opt-in. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/policy.cjs, install/git-context.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-26T14:38:07.104Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook gathers installation and Git configuration details and posts the resulting event to the Hashbrown telemetry endpoint. - **Rationale:** Static source inspection confirms automatic installation telemetry can include Git identity and is sent to the publisher's endpoint without affirmative opt-in. The publisher-aligned recipient and opt-out controls reduce the risk, and the source does not establish credential theft or another concrete attack. - **Files touched:** install/postinstall.cjs, install/collector.cjs, install/policy.cjs, install/git-context.cjs - **Network endpoints:** https://hashbrown.dev/\_/growth/collect/v1/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs an install collector automatically from its postinstall hook., The collector sends install events to a fixed Hashbrown telemetry endpoint and includes discovered Git identity in the event., Git discovery reads global and checkout configuration and can add the user's Git display name and email to the event., Collection is automatic unless a telemetry opt-out is set; the source does not require affirmative consent. - **Evidence against:** The recipient is the package publisher's Hashbrown telemetry endpoint, and the collector provides opt-out controls., The collector sends package and environment metadata for an install event; the source does not establish credential collection or a separate malicious action. ## Affected versions and remediation This report applies to @hashbrownai/anthropic@0.8.2. - Review the evidence and your use of @hashbrownai/anthropic@0.8.2 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.
