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. Source confirms an automatic installation beacon that can disclose persistent identifiers and personal Git details without affirmative consent. The recipient is package-aligned and the source provides opt-outs, so the evidence supports a warning rather than a publication block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-23T04:28:23.473Z - **Finished:** 2026-10-23T04:29:42.103Z - **Download time:** 771 ms - **Static scan time:** 233 ms - **AI review time:** 77626 ms - **Total time:** 78630 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 automatically reports identifying environment and checkout details to Hashbrown telemetry. - **Trigger:** The package manager runs the postinstall hook. - **Impact:** The package publisher receives installation and potentially personal Git identity information without an affirmative consent step. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/policy.cjs, install/identity.cjs, install/git-context.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-23T04:29:42.103Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The collector sends an installation event with a persistent per-user identifier and environment data; outside CI it can include Git identity and repository context. Collection is enabled by default, with opt-out variables available. - **Rationale:** Source confirms an automatic installation beacon that can disclose persistent identifiers and personal Git details without affirmative consent. The recipient is package-aligned and the source provides opt-outs, so the evidence supports a warning rather than a publication block. - **Files touched:** install/postinstall.cjs, install/collector.cjs, install/policy.cjs, install/identity.cjs, install/git-context.cjs - **Network endpoints:** https://hashbrown.dev/\_/growth/collect/v1/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs a postinstall hook, which invokes the collector during package installation., The collector builds an installation event with package, platform, runtime, package-manager, environment, and checkout context details., Outside CI, the event may include the configured Git display name and email; it is sent to a fixed Hashbrown collection endpoint., The collector sends by default unless an opt-out variable is set; endpoint overrides are limited to loopback hosts. - **Evidence against:** The collection endpoint is on the Hashbrown domain and accepts installation telemetry for Hashbrown packages., Several telemetry opt-out variables are supported, and the collector does not follow redirects or use the response to configure behavior. ## Affected versions and remediation This report applies to @hashbrownai/anthropic@0.8.0. - Review the evidence and your use of @hashbrownai/anthropic@0.8.0 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.
